4 1 INTRODUCTION & METHODOLGY 1.1 OBJECTIVES The key objectives of this study were: 1. To provide marketing data on biocides, major personal care products using biocides, suppliers and customers. 2. To identify and analyse the trends taking place within the biocides industry. 3. To define the distribution channels in the industry. 1.2 METHODOLOGY The report is based on over 30 interviews conducted throughout the globe. In each industry analysis, BI contacted Personal Care Product manufacturers, biocide manufacturers, Suppliers, Distributors and trade associations by telephone and conducted unstructured interviews typical of the type used in industrial market research. In addition to interviews, the report also summarises suppliers' product literature, data from trade associations, BI databases and our monthly information report. 1.3 ACCURACY OF THE INFORMATION BI believes our estimates to be within 20% of the actual value. The accuracy of the information is dependent on many factors such as the number of interviews conducted per application, industry concentration and industry usage patterns. In order to increase our accuracy, BI increases the number of end-user interviews where an industry is fragmented and continues to interview until there is similarity in responses. Also all conclusions and data per industry were confirmed with the key manufacturers of biocides. 1.4 DEFINITIONS Biocide manufacturers are defined as companies who manufacture biocide active ingredients in-house. For example Ashland, BASF, Clariant, Corbion, DowDuPont, Emerald Kalama, Galaxy, Guangzhou Tinci, Lanxess, Lonza, Merck, Salicylates, Schulke, Shandong Ailitong, Sunpu, Symrise, Thor and Vivimed. CHAPTER

5 Biocide Blenders / Formulators are defined as companies whose majority of sales comes from purchasing biocides which they blend into their own products. For example Chemipol, Induchem, Inolex, Jeen, Lincoln Manufacturing, Lipo, Protameen, Rita, Schulke & Mayr, Sharon Laboratories and Tri-K etc. Distributors act as agents for both active manufacturers and biocide blenders. They are the most popular choice of supplier for small end-users. Distributors sell a range of additives and so will be making deliveries to end users and therefore biocides tend to be combined with other products which allow the distributor to be competitive. Prices are in U.S. dollars and are at active manufacturer level unless stated. The exchange rates used are as in Table 4 Table 4: Currency Conversion Rates $ Currency EUR CNY JPY GBP Source: Volumes are reported in tonnes based on a 100% active biocide basis. In the case of formulated products, the data is reported with a typical percentage of the formulated product. CHAPTER

6 2 END USER ANALYSIS 2.1 TARGET MARKET Biocides are used in personal care applications to inhibit or kill microorganisms in the product while a smaller amount are used to inhibit or kill microorganisms on the end user. The specific functionality in the product determines a biocide's status as a bacteriostat, antidandruff agent or preservative. As a result, the biocides analysed in this report can be classified into three main types: (1) Preservatives (2) Bacteriostats (3) Antidandruff Agents. Preservatives are used in the majority of personal care products while a limited range of personal care products contain bacteriostats and antidandruff agents. For example, antidandruff shampoos contain a preservative in addition to an antidandruff agent. The personal care industry is comprised of a wide variety of products used to cleanse, protect or beautify the body. Personal care products are generally classified into four categories: (1) Toiletries (2) Skin Care (3) Colour Cosmetics (4) Fragrances. Toiletries are the largest group within the personal care industry and include such products as shampoos, mouthwashes and deodorants. Typically formulated with aqueous compounds, toiletries are particularly susceptible to microbial contamination. The majority of toiletries must have biocides to protect them before and during usage. Skin care products are used to soothe and refresh the skin. They are also formulated with aqueous compounds and therefore must have effective and long lasting preservation systems to protect the products before and during consumer use. Colour Cosmetics include face makeup, lipstick and nail colouring. They are not normally formulated with aqueous compounds but may become contaminated with water during use and must therefore be preserved. Preservatives are used in these formulations to prevent contamination with potentially pathogenic microbes e.g. eye makeup preservation as the eye is vulnerable to microbes such as Pseudomonas. The most common microbial contaminants that personal care products can be exposed to are described in the following table:. Table 5: Main Microbes Found in Personal Care Products BACTERIA MOLDS YEAST Aerobacter spp. Alternaria spp. Candida spp. Alcaligines spp. Aspergillus spp. Cryptococcus spp. Bacillus spp. Botrytis spp. Saccharomyces spp Escherichia spp. Cladosporium spp. Zygosaccharomyses Pseudomonas spp. Mucor spp. Sarcina spp. Penicillium spp. Staphylococcus spp. Rhizopus spp. CHAPTER

10 3 BIOCIDE COMPARISON 3.1 PRESERVATIVES Preservatives are used in personal care products to prevent product spoilage by microbial contamination and growth. Preservatives are selected for their ability to kill contaminating bacteria, fungi and molds over the use-life of the products, while not exhibiting skin irritation or sensitization. It is commonly accepted that different biocides will not perform equivalently in any given system, making a true comparison of cost effectiveness impossible. However, the relative costs can be approximated by comparing suppliers prices and recommended use levels for the most typical personal care formulations. Some common preservatives used in personal care formulations are shown along with their trade name, suppliers and prices in the following table:. Table 9: Comparison of Preservatives used in Personal Care Chemistry Trade Name Supplier % AI in Formulated Price formulation $/Kg 2-Brono-2-nitro propane-1,3 diol Bronopol BASF 100% 8 Benzoic acid, Euxyl K701 Schulke & Mayr 12 dehydroacetic acid, ethylhexylglycerin, phenoxyethanol CMIT/MIT Kathon CG DOW 1.5% 5 DMDM Hydantoin Glydant Lonza 55% 8 Diazolidinyl Urea Germall 11 Ashland 100% 10 Imidazolidinyl Urea Germal 115 Ashland 100% 10 Methyl paraben Nipastat Clariant 100% 4 Propyl paraben Nipastat Clariant 100% 4 Phenoxyethanol Phenoxetol Clariant 99% 6 Quaternium 15 Dowicil 200 Dow 95% 20 CHAPTER

11 3.2 ANTI-MICROBIAL COSTS IN SYSTEM Biocides are included in raw material costs and as shown in the following table, the cost of treating personal care products with a preservative ranges between $ 5 per tonne to $120 per tonne and amounts to a maximum 3% of raw material costs (Assume costs of raw materials is $4,000 / tonne). The costs of using antidandruff agents is more expensive than preservatives and can be up to 22% of the total raw material costs as shown in the following table:.

CHAPTER

12 4 BIOCIDE CONSUMPTION 4.1 GLOBAL AND REGIONAL ANALYSIS The global market for Biocides in Personal Care products is $ 954 million. Europe is the leading region for Biocide consumption. The leading Biocides consumed in the global Personal Care products market are alcohol type with sales of $ 187 million as shown in the following table which segments the market by biocide active ingredient per geographical region:. Table 11: Biocide Sales by Type within Personal Care BIOCIDE AMERICAS ASIA PACIFIC EUROPE GLOBAL ($M) ($M) ($M) ($M) Alcohol Amines Bronopol Chlorhexidine Chlorphenesin Climbazole CMIT/MIT Formaldehyde Releasers (including dmdm hydantoin, quaternium ) IPBC Ketoconazole MIT Organic Acids Parabens Phenolics PHMB Polyaminopropyl biguanide Piroctone Olamine Quats Selenium Sulfide Silver Triclosan Zinc pyrithione Other TOTAL Alcohols are widely used in the personal care industry with sales of $ 187 million. Alcohols are used as preservatives and bacteriostats. Alcohols can be divided into lower molecular CHAPTER

13 type alcohols which are used for disinfecting hands and surfaces whereas the higher molecular type alcohols tend to be used as preservatives. Phenoxyethanol is the leading alcohol used accounting for nearly 70% of consumption. Phenoxyethanol is followed by benzyl alcohol at 20 % and the remainder includes phenethyl alcohol, phenylpropanol etc. Bronopol has sales of $ 22 million. Bronopol is extremely effective in combination with numerous other biocides, for example certain isothiazolones, quarternary ammonium salts and IPBC. Using these biocides together with bronopol will provide synergistic benefits which are less expensive, and reduces application rates. The leading manufacturer of Bronopol is BASF followed by DOW and numerous generic manufacturers. 5-Chloro-2-methyl-4-isothiazolinone and 2-methyl-4-isothiazolinone (CMIT/MIT) has sales of $ 38 million within the global personal care industry. The CMIT/MIT biocides are used in a ratio of 3:1 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one (CMIT/MIT). They are supplied as a 1.5% aqueous solution. The leading manufacturer is DOW. CMIT/MIT has broad activity against both Gram-positive and Gram-negative bacteria and it is also very effective against yeast. It is effective over a broad ph range from 1-8. CMIT/MIT can be used alone or in combination where it offers the following benefits: (1) Broad spectrum antibacterial activity (2) Low cost effect in low ph systems (3) Broad regulatory approvals (4) Low VOC / solvent free (5) Pale colour (6) Speed of kill. The major disadvantages to CMIT/MIT are: (1) Chlorinated (2) Unstable at high ph (3) Inactivated by amines (4) Poor temperature stability (5) Deactivated by reducing agents (6) Requirement for stabilisers such as formaldehyde or metal ions (7) Skin sensitiser (8) Volatile 1,1-Hexamethylene-bis 5-p-chlorophenyl biguanide gluconate (Chlorhexidine) is used within preservation of personal care products and Oralcare with sales of $ 10 million. It is popular as it has excellent persistence, good activity against all microorganisms, low toxicity and irritancy. The main disadvantages are poor biodegradability and discolouration to teeth. The leading suppliers of Chlorhexidine are Evonik, Medichem, Mölnlycke Health Care, RN Pharmaceuticals, Schutz and Xttrium. Chlorhexidine is used within the Corsodyl Mouthwash range from GSK which contains 0.2% Chlorhexidine Gluconate and 5.7 % Ethanol. Climbazole is a popular antidandruff agent used in personal care products with sales of $ 19 million at active manufacture level. Climbazole is sold as a 100% active powder and the product is used in antidandruff shampoos at use levels ranging from 1% and 2% by weight. Due to regulatory restrictions, Climbazole is only registered to be used in Asia and Europe. Bayer is the leading manufacturer of climbazole and the product is licensed to Symrise for the personal care industry. Symrise has many patents on the use of climbazole in antidandruff shampoos. CHAPTER

14 Formaldehyde Releasers provide a broad spectrum of antibacterial and antifungal activity with a relatively rapid speed of kill. They have combined sales of $ 81 million to the personal care industry. The most popular formaldehyde releaser used in the personal care industry is DMDH Hydantoin. It is effective against gram positive and gram negative bacteria. It is used in combinations with CMIT/MIT, parabens, quats or iodopropynyl butyl carbamate to provide a broader spectrum of activity in stay-on and rinse-off products. It has good water solubility which makes it a popular choice for clear products. The leading manufacturer of DMDM Hydantoin is Lonza who also provide it in a number of formulations with other actives i.e. IPBC. The second most popular group of formaldehyde releaser biocides are Diazolidinyl urea / Imidazolidinyl urea. They are highly effective against gram-positive and gramnegative bacteria. Diazolidinyl urea / Imidazolidinyl urea are often used in combination with parabens. Leading end uses include leave on products such as colour cosmetics, facial treatments, hand and body products and sun care preparations. Ashland is the leading manufacturer of Diazolidinyl urea / Imidazolidinyl urea followed by generic producers. Another popular formaldehyde releaser is sodium hydroxymethylglycinate. Another formaldehyde releasers used in the Personal Care industry is Quaternium 15 which is the designated name for 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride and is a formaldehyde donor. Quaternium 15 is active against gram-positive and gram-negative bacteria, as well as yeasts and moulds. It is effective against such gram-negative bacteria as pseudomonas aeruginosa and pseudomonas cepacia. Quaternium 15 is mainly used in creams, eye makeup and shampoos. The main manufacturers of formaldehyde releasers are Ashland, Clariant, DOW, Lanxess, Lonza, Schulke & Mayr, Thor and Troy. 3-Iodo-2-propynylbutyl carbamate (IPBC) has sales of $ 16 million and is used within the personal care industry where antifungal activity is required. IPBC can be supplied in a VOC free formulation and is very effective against mould fungi. The leading supplier of IPBC blends to the Personal Care industry are Lonza and Ashland. Ketoconazole is the second most popular antidandruff agent used in personal care products with sales of $ 27 million at active manufacture level. Ketoconazole is sold as a 100% active powder and the product is used in antidandruff shampoos at use levels ranging from 1% and 2% by weight. Johnson & Johnson is the leading consumer of the product which is used in the Nizoral line of antidandruff shampoos. Janssen is the leading manufacturer of ketoconazole for the personal care industry. CHAPTER

15 2-methyl-4-isothiazolinone (MIT) is used as a preservative within the personal care industry with sales of $ 24 million. The biocide was developed and patented by DOW (tradename is Neolone). MIT has a lot of the benefits of CMIT/MIT without the chlorine. The product is used as a preservative where it can be used alone or in combination with other biocides. MIT has global regulatory approval for the personal care industry, a key criteria in the selection process for biocides at some multinationals. For the future, MIT will decrease in sales as regulatory authorities restricts its use to ineffective levels. Organic Acids are widely used as preservatives in the Personal Care industry with sales of $ 173 Million. Organic acids are helpful against microbes as low ph suppresses microbial growth and spore germination is delayed. The leading organic acids used in the personal care industry are benzoic acid, sorbic acid and dehydroacetic acid. Less popular organic acids used in the Personal Care industry are Acetic Acid, Formic Acid, Lactic acid, Propionic Acid and Salicylic Acid. Some organic acids do not make any preservative claims and so do not have to be registered as a biocide. This makes them attractive to biocide formulation and personal care manufacturers. There is a trend towards organic acids due to the perceived notion that they are safer than synthetic chemicals. The main disadvantage of organic acids are the high dosages required to achieve an effect as illustrated in the table below: Table 12: Minimum Inhibitory Concentration for Natural versus CMIT/MIT BIOCIDE MIC Value (ppm) Aspergills Niger MIC Value (ppm) Pseudomonas Aeruginosa Benzoic Acid CMIT/MIT 4 4 Dehydroacetic acid ,000 Parabens were the number one biocide used in personal care products but their sales are declining and now estimated at $ 65 million. Parabens are esters of parahydroxybenzoic acid where the ester can be methyl, ethyl, propyl, butyl etc. They are more effective than organic acids at higher ph levels. Parabens are used most often for their activity against yeast and mould. Methyl paraben is more water soluble than propyl paraben and is considered more effective in certain formulations. These formulations are often incorporated in a ratio of 2:1 of methyl to propyl parabens. The leading manufacturer of Parabens is Clariant followed by many generic producers such as Napp, Protameen, Salicylates & Chemicals and Ueno. Sales of parabens will continue to decline in the future as they are being restricted by governments and industry associations. For example, the Danish authorities introduced a ban on the use of propyl- and butyl-paraben in products for children under the age of three. In addition, the CHAPTER

16 Scientific Community on Consumer Safety (SCCS) has proposed a complete ban on isobutyl-paraben and to restrict the amount of propyl- and butylparaben to 0.19% in cosmetic formulations. Piroctone Olamine is a popular antidandruff agent especially in Europe with sales of $ 15 million at active manufacture level. Piroctone olamine is sold as a 100% active powder and the product is used in antidandruff shampoos at use levels of 1% by weight. Clariant is the leading manufacturer of piroctone olamine. Clariant is followed by generics such as Ecochem based in China. Polyhexanide (polyhexamethylene biguanide, PHMB) is a polymer used as a preservative in make-up removers, cleansing tissues with sales of $ 7 Million. It was classified under the CLP Regulation as carcinogenic since January L Oreal is the single biggest purchaser of PHMB where it widely used in their makeup removers via their brands Garnier, Vichy and La Roche-Posay. Since the ban, Beiersdorf has removed PHMB from all their make-up removers and replaced with Benzethonium chloride. The leading supplier of PHMB is Lonza followed by Pareva and Chinese producers. Polyaminopropyl biguanide (PAPB) is used within deodorant body sprays and cleaning solutions for contact lens with sales of $ 8 million. It is popular as it has excellent persistence, good activity against all microorganisms, low toxicity and irritancy. The leading suppliers of PAPB are Lonza (Cosmocil CQ) and Quingdao Kingnod Chem in China. Quaternary ammonium compounds (or quats) are used as bacteriostats and preservatives in the personal care industry with sales of $ 51 million. A large number of quats are offered to personal care manufacturers and formulators, differing by type and alkyl group length chain. The most popular quats in the personal care industry is cetylpyridinum chloride which is used in mouthwashes and feminine deodorants. The leading suppliers of cetylpyridinum chloride are Vertellus and Jubilant. Benzethonium chloride is widely used in underarm and foot deodorants. It is used at levels of up to 5% in products that stay on the skin. Alkyl dimethyl ammonium chloride (ADBAC) is used within personal care products exhibiting disinfectant purposes. Other popular quats are dialkyl dimethyl ammonium and benzyl/ethyl ammonium chloride. Lonza is the leading manufacturer of Quats to the personal care industry, followed by Akzo, Jubilant, Mason, Stepan and Vertellus. Selenium Sulfide is used as an antidandruff agent in personal care products with sales of $ 19 million at active manufacture level. Selenium sulfide is also known as selenium disulfide, is CHAPTER

17 a bright orange powder prepared from selenious acid and hydrogen disulfide. Selenium sulfur is incorporated into a formulation in a precipitated or colloidal form and is used as a relatively inexpensive antidandruff agent. Chattem (100 % owned by Sanofi-Aventis) is the leading producer and consumer of the product, which is used in the Selsun Blue line of antidandruff shampoos. Silver consumption in Personal care is estimated at $ 1.8 million at manufacture level. Silver is widely used in Japan. Silver is normally supplied as a 1% - 3% a.i. formulation and added by a number of methods to give 0.1% in the final product. Silver is supplied with carriers such as glass, zeolite, zirconium phosphate, titanium dioxide, ceramics and silica gel. The silver ion is gradually released from the carriers and becomes an active biocide. The costs of silver formulations are $150 per kg. Ishizuka, Kanebo, Sinanen and Toagosei are the leading manufacturers of silver. Triclosan (2,4,4 -Trichloro-2-hydroxy-diphenylether) is used as a bacteriostat in body washing cleaners, deodorants, toothpaste and mouth rinses with sales of $ 23 million. Triclosan is suitable for such applications as it is odour free, kind to the skin and very effective against gram positive bacteria. The product is relatively insoluble and is normally incorporated into personal care products by predissolving it in a surfactant concentrate. Triclosan allows personal care manufacturers to make antimicrobial claims. The leading manufacturer of triclosan is BASF followed by Generic producers. Triclosan is supplied as 96% active substance in powder form and in formulations with varying active substance concentration. The leading enduser is Colgate who use triclosan within their oralcare range of products. Triclosan (100% ai) is used at 0.2% of the final product. Zinc pyrithione is the leading biocide used in personal care products with sales of $ 113 million at active manufacture level. Zinc pyrithione is sold as a 48% active dispersion and as a 100% active powder. The product is used in various antidandruff shampoos at use levels ranging from 1% - 2% by weight. Procter & Gamble is the leading consumer of the product which is used in the Head and Shoulder line of antidandruff shampoos. Lonza is the leading manufacturer of zinc pyrithione followed by API and Janssen for the personal care industry. OTHER has sales of $ 34 million and includes a broad range of products including allantoin, dipyrithione, dibromo dicyanobutate (CTFA adopted name ismethyldibromo glutaronitrile), sodium pyrithione, natural biocides which are on annex of cosmetic regulations. Methyldibromo glutaronitrile is extremely effective in combination with numerous other CHAPTER

18 biocides such as phenoxyethanol, isothiazolones and IPBC. For the future, sales of methyldibromo glutaronitrile will decline due to sensitisation. The leading supplier of methyldibromo glutaronitrile is Lubrizol. 2-Dibromo-2,4-dicyanobutane is used primarily for its activity as a preservative. The primary source of exposure is Euxyl K-400 in which it is combined with phenoxyethanol in a 1:4 ration. Euxyl K400 is effective at low concentration against both bacteria and fungi for the preservation of cosmetic and personal care products. The most popular formulation is methyldibromoglutaronitrile (MDGN) + phenoxyethanol, and it is sold under the trade name Euxyl K-400. It was once a very popular cosmetic preservative in Germany. The manufacturer (Schulke & Mayr, Hamburg, Germany) recommends a use concentration between 0.05% and 0.02% depending on the product to be preserved. 1,2- Dibromo-2,4-dicyanobutane is also been available as a biocide in latex paints, plastic dispersion paints, adhesives and metalworking fluids under the trade name Tektamer 38. Within the EU Dibromodicyanobutane is only allowed in rinse-off cosmetics, e.g. in showergels, bath -gels, washing emulsions, shampoos. Many of the other materials are used in natural preservatives which are growing in usage within the Personal Care industry. A recent example was Vedeqsa, a subsidiary of Spanish company Lamirsa, who introduced AMINAT and AMINAT-PQ to the Personal Care industry. The active ingredient is LAE or Lauric arginate. CAS number: INCI name: Ethyl lauroyl arginate HCl. The composition: 20% LAE in propylene glycol. AMINAT-PQ will be sold as an Antimicrobial agent for oral care products, especially mouth wash solutions and toothpastes. It will be sold as an Antimicrobial for antiseptic hand wash products and deodorants. The Saltigo active ingredient Saltidin -in chemical terms 1-(1-methylpropoxycarbonyl)-2-(-2- hydroxyethyl)piperidine or simply icaridin -is not an insecticide. It simply repels insects by acting on their odorant receptors, disabling their ability to recognize humans as blood donors. Consumer organizations give top marks to insect repellents containing the active ingredient Saltidin, and it is recommended by the World Health Organization (WHO) as the substance of choice for malaria prophylaxis. "Unlike other repellents, Saltidin does not attack coatings or plastics and is virtually odorless. Furthermore, it does not have a sticky feel on the skin," says Dr. Christoph Peters, Saltidin Business Manager at Saltigo. 4.2 MULTI-FUNCTIONAL INGREDIENTS There is a trend towards combining biocides with multi-functional ingredients (do not appear on annex of cosmetic regulations as preserving is not their main function). Such products are growing due to the perceived notion that they are more natural than synthetic biocides. Multifunctional ingredients include a broad range of material such as glycol, herbs, plant extracts, mineral raw materials and vitamins. We estimate the following multi-functional ingredients to CHAPTER

19 be the most popular: Caprylyl glycol (increases activity of certain preservatives), Ethylhexyl glycerin (decrease surface tension of cell membranes thereby increase contact surface for preservatives), Caprylic acid (increase activity of certain preservatives), Glyceryl caprate (as above), Ethylenediaminetetraacetic acid (EDTA Chelator) (increase permeability of cell membranes, making them more sensitive to preservatives. Currently it is estimated that 20 % of all personal care products are not using preservatives due to product packaging and/or composition making preservatives unnecessary. The personal care companies use certification organisations, such as Ecocert (based in France), BDIH*{BundesverbanddeutscherIndustrie-und Handelsunternehmen}, NaTrue in Germany, The Soil Association in the UK, National Organic Program in USA to certify their products. Ecocert is Europe s best known certification body for organic products working in more than 80 countries worldwide. The demand for its certification is growing, but is a relatively recent trend. Valerie Lemaire for Ecocert comments: Ecocert is working on European harmonization with other European certification bodies from Italy, Germany and England to set up common European standards. It is normal to combine multi-functional ingredients with conventional and mild preservatives. The following are popular preservative formulations with multifunctional ingredients: Activon is Korean and developing sustainable active ingredients like propanediol via Biotechnology. The company supplies personal care companies in Asia with Activonol-PAF E91 (Phenoxyethanol & Ethylhexylglycertin) Activonol-3 is propanediol and 100 % natural glycol derived from biofermentation process. It is used as solvent, humectant, emollient and preservative booster Activonol -5 has pentylene glycol which is a moisturizer and solvent and good antimicrobial effect and excellent synergistic antimicrobial effect with glycols and preservatives Activonol-6 is 1,2-Hexanediol which can be used solely as an antimicrobial. Active Microtechnologies focuses on preservation alternatives in the Personal Care and Cosmetics Industry. They supply Synercide Herbal Fusion which contains Synercide Herbal Fusion which consists of oregano, thyme and rosemary extracted in caprylyl and hexylene glycols. In this system, the glycols act as more than just a solvent as they are understood to provide emollient and humectant properties. INCI Name:Hexylene Glycol (and) Caprylyl Glycol (and) Origanum Vulgare Leaf Extract (and) Thymus Vulgaris (Thyme) Leaf Extract (and) Rosmarinus Officinalis (Rosemary) Leaf Extract (andacterial and antifungal ingredients derived from citrus fruit. The Israel-based company has created an extraction method to harness the preservative power of citrus peel. CHAPTER
