1 AMAZE XT POLYMER (28-29A) Dehydroxanthan Gum Performance naturally Today s consumers are educated, driven to succeed and demanding. They want healthy hair that looks good and feels good. Individuality is very important a driving factor in their quest for a look of their own. They use their hairstyles as forms of self-expression. And, they want their hair styling products to be as individual as they are, while providing exceptional performance. AMAZE XT styling polymer provides the benefits that meet these needs by offering unprecedented lasting hold with good feel and minimal flaking. It raises the bar on performance from hair styling gels like nothing before. APPLICATION AREAS AMAZE XT is a naturally derived, multifunctional styling polymer. It has been developed to provide outstanding long-lasting hold under highly humid conditions, without the tack and flaking often associated with gels. AMAZE XT offers not only the fixative properties, but it also serves as the thickener, simplifying the formulation and manufacturing process. It is suitable for use in gels, glazes, spray gels, mousses, creams/lotions, pomades and other styling aids. FEATURES/BENEFITS Long lasting hold under high humidity Multi-functional: fixative and thickener/suspending agent Ease of use: easily dispersed with no neutralization required Smooth feel Ease of detangling and combing (less mechanical hair damage) Minimal flaking Restylability Naturally derived AMAZE XT INCI Name : Dehydroxanthan Gum Typical Properties: Appearance Off-white free flowing powder ph (1% solution) ~ 5 Viscosity (1% solution) ~ 3, cps Viscosity (2% solution) ~ 5, cps Europa: Sempach-Station, Switzerland, Tel: +41 () , Fax: +41 () , personalcare.europe@nstarch.com Americas.: Bridgewater, New Jersey, U.S.A., Tel: , Fax: , personalcare.usa@nstarch.com Asia/Pacífico: Singapore, Tel: , Fax: , personalcare.asia@nstarch.com

2 PERFORMANCE PROPERTIES AMAZE XT offers unprecedented style retention under high humidity conditions compared to competitive polymers marketed for use in styling gels. Hair that is treated with AMAZE XT exhibits 95% curl retention after 24 hours at 7 F and 9% RH, a 4% improvement over the next best performing competitive polymer (Figure 1).

Figure 1: AMAZE XT gives unprecedented shape protection to curls, even in highly humid conditions, maintaining 95% curl retention after 24 hours. Subjective evaluations were conducted by trained panelists on hair tresses to determine the performance of AMAZE XT compared to a traditional gel system. In this study, hair tresses were treated with a 1% AMAZE XT gel, a 2% AMAZE XT gel, or a 4% PVP K- 9/Carbomer gel. The panelists evaluated the hair tresses both in a wet and a dry state. As shown in Figure 2, regardless of use level, AMAZE XT showed significant improvement over the PVP gel in dry comb, dry feel, dry detangling, and wet feel. Stiffness is a performance benefit that can be altered by varying the level of AMAZE XT. In this figure, the 1% AMAZE XT gel is considered less stiff than the 4% PVP gel, while the 2% AMAZE XT gel is considered similar in stiffness. Dry Comb * Dry Detangling * Stiffness Figure 2: AMAZE XT is significantly superior in wet and dry feel, dry detangling, dry combing and flaking compared to a traditional PVP gel. It has been observed that the AMAZE XT gels are not as tacky as traditional gels. To verify this, eight panelists were asked to apply a 1% AMAZE XT gel into one hand and a 4% PVP K-9 gel into the other. The panelists rubbed the gels into the hands until dry and identified the hand/gel with more residual tacky feel. Unanimously, the panelists determined the AMAZE XT gel to be less tacky (Figure 3).

3 AMAZE XT is unique in that it serves as both the fixative and the thickener, allowing for the production of a hair styling gel with only one ingredient. It easily disperses into water, reducing the gel manufacturing time significantly compared to PVP/Carbomer. To demonstrate this, 1g batches were made side-byside in the laboratory. The time required to put the PVP K-9 into solution and hydrate the carbomer was nearly six times longer than that required to disperse the AMAZE XT (Figure 4).

Figure 5. Viscosity increases with increasing use levels of AMAZE XT. To better understand the flow properties of AMAZE XT several experiments were conducted to determine the effect of shear on the gel. In the first study, a 1% AMAZE XT gel was compared to a leading commercial gel (PVP/carbomer based). The viscosity of the gels was monitored while increasing rates of shear were applied. As seen in Figure 6, the AMAZE XT gel has shear thinning pseudoplastic rheological flow, similar to the commercial gel. Rheological Profile SOLUTION PROPERTIES Because AMAZE XT is multi-functional, it is important to understand its solution properties. As shown in Figure 5, the solution viscosity increases with increasing concentrations of AMAZE XT.

4 In addition to flow properties, it is equally important to know the gel behavior once the shear is removed. Figure 7 shows the results of a study whereby the viscosities of the 1% AMAZE XT gel and the commercial (PVP/Carbomer) gel are evaluated first at low shear, followed by high shear and then low shear once again. The AMAZE XT gel demonstrates that it is shear thinning, and recovers quickly following high shear. Viscosity (Pas) Viscosity Recovery Following High Shear 1% AMAZE XT Commercial gel (PVP/Carbomer) Time (s) Figure 7: AMAZE XT gels provide easy application for consumers. The high shear experienced from rubbing the gel between the hands reduces its viscosity, allowing for good spreading through the hair. Once on the hair and the shear has been reduced, the viscosity rebuilds to its original level, keeping the gel in place and preventing dripping. In addition to its thickening abilities, AMAZE XT acts as a suspending agent. When a 1% AMAZE XT gel is subjected to low levels of stress, it remains relatively undisturbed. It has a high elastic/storage modulus (G ), indicating good suspending ability (Figure 8).

Encapsulation beads and air bubbles are known to remain suspended in AMAZE XT gels for 3 months in a 45 C oven. AMAZE XT gels are affected by varying ph (Figure 9a,b) and by the addition of high levels of salt (Figure 1a,b). The peak viscosity can be achieved at ph As the ph decreases, the gel clarity is reduced, and conversely, the gel clarity improves slightly with increasing ph. The addition of monovalent salt (>.25%) to an AMAZE XT gel causes the viscosity to decrease. Although a gel structure is still maintained, it can reduce the clarity of the system. Lower levels of monovalent salt (e.g. sodium chloride) or divalent salt (e.g. calcium acetate) at less than.1% will not affect the viscosity or clarity of an AMAZE XT gel.

6 UV Stability Another factor to consider regarding gels is the impact of UV light. Typically, a UV filter is added to traditional PVP/Carbomer systems to protect the gel integrity from the damaging effect of UV light. To better understand the UV stability of AMAZE XT gels a study was conducted whereby an AMAZE XT gel and a PVP/Carbomer gel, with no UV filters, were exposed to UV light in a controlled chamber for 4 weeks. After the exposure period, the gels were removed from the chamber. The PVP/Carbomer gel showed a color change from water white to yellow, and it exhibited a destruction of the gel structure, with a significant loss of viscosity. The AMAZE XT gel showed good stability under UV light with no change in color, clarity or viscosity. Unlike PVP/Carbomer systems, AMAZE XT gels do not require the addition of sunscreen for protection of the gel integrity. COMPATIBILITY WITH OTHER INGREDIENTS AMAZE XT is anionic in nature and is compatible with a wide range of materials commonly used in gels, such as silicones, propylene glycol, glycerin, proteins, vitamins, disodium EDTA, tetrasodium EDTA, sodium phosphate and low levels of FLEXAN II (Sodium Polystyrene Sulfonate). A blend ratio of 3:1 AMAZE XT:FLEXAN II is recommended. For emulsion products such as creams, lotions, and low viscosity glazes, AMAZE XT can be formulated with cationic polymers (e.g. <.5% CELQUAT H-1). It can be used with other styling polymers like acrylate (including the AMPHOMER, BALANCE series) polymers, polyurethane polymers (including DynamX ), as well as with PVP and PVP/VA. If desired, it can also be combined with additional thickeners (e.g. Carbopol series, STRUCTURE XL, STRUCTURE 21, STRUCTURE 31, native xanthan gum, or hydroxyethylcellulose). Formulation Guidelines Supplied as a free-flowing powder, AMAZE XT is very simple to use. No heating is required, and it goes into solution very quickly, with no neutralization required. Solubility AMAZE XT is soluble in water and ethanol (< 3%). Clarity is maintained in hydroalcoholic solutions where the ethanol level is less than 3%. Neutralization AMAZE XT requires no neutralization. Preservative Systems Glydant Plus Liquid (DMDM Hydantoin and Iodopropynyl Butylcarbamate) is the most effective preservative system for AMAZE XT. A recommended starting level is.3% Glydant Plus on a liquid basis. Other recommended preservatives are Geogard 221 (Dehydroacetic Acid and Benzyl Alcohol) and Natrulon PC-15 (Cinnamaldehyde and Potassium Sorbate). Paraben-based preservatives may reduce the viscosity of AMAZE XT gel formulations.
