FEATURES Subject to Japanese standards as for QD ingredients: highly rated in terms of safety IPD performances: Solubilising (hydrotrope) & humectant properties Manufacturing aid : processes of many cosmetic formulations made easier Improves sensory profiles of finished products Repair effect on damaged hair IPD can be easily added to cosmetics formulae, even in consistent amounts without inducing instability
& BENEFITS Addition of hydrophilic actives in anhydrous systems or lipophilic into aqueous systems made easier Efficient skin moisturiser Enhanced skin feel in toiletries, skin care & make-up Foam & viscosity booster in sodium lauryl ether sulphates (SLES) based systems Binder-aid in compact powders Repairing effect on damaged hair Reduces ethanol content in fragranced formulae
FORMULATING with IPD Hair and body cleansing formulae Good thickening effects & interesting foam properties After-shave gel Reduces sticky feel of the formula Liquid foundation Increases transparency & natural look without affecting spreadability, shine & massage time Lipstick Supports a high gliding application, the uniformity of the trace and the long-lasting shine effect Eye-shadow Improves shine & resistance to breakage Toothpaste Replaces PEG-8 leading to an improvement of the foam & a decrease of the viscosity control without changing the product taste
MISCIBILITY OF IPD * Asymmetric chemical structure (very hydrophilic & completely lipophilic non-polar site) Fully miscible in water, with some polar fatty esters (adipates, sebacates, ratio 1/1) Not soluble in Caprylic/capric triglyceride, vegetable oils, silicone oils, polydecene CARRIER & SOLUBILISER * Good solubiliser of lipophilic actives (e.g. Salicylic acid, resveratrol) Acts as a carrier of: hydrophilic actives in anhydrous systems lipophilic actives in aqueous systems Solubilises difficult actives such as glycyrrhetinic acid, salicylic acid, resveratrol or Boswellia serrata extracts leading to clear solutions at room temperature *Studies performed by Dr Luigi Rigano
WETTING & DISPERSION PROPERTIES * Good wetting properties with FeO2, (ratio 1/1) & with TiO2 (ratio 4/5) Shows better dispersion properties with silica powders than glycerine or sorbitol Helps polymers in powder form to swell more rapidly in water (pre-gel), e.g. Xanthan Gum, cellulose gum, Aristoflex AVC at room temperature Improves clarity of aqueous gels made of these polymers with no variation of viscosity (except with hexyl ethyl cellulose at 1% where viscosity is boosted) COMPATIBILITY with SURFACTANTS SYSTEMS * When used @ 1-1.5%, viscosity of SLES system is boosted, foam & stability are increased In mild surfactant systems, optimum value of IPD is 2% Improved skin feel with more emollience vs. reference *Studies performed by Dr Luigi Rigano
COMPATIBILITY in O/W EMULSIONS * Combining IPD & waxy emulsifiers leads to pasty/viscous blends that are easier to use (energy saving) STABILITY & PARTICLE SIZE * When used @ 5% in the water phase, oil droplets are finer compared to the same formula without IPD (anti ageing cream) O/W emulsion *Studies performed by Dr Luigi Rigano
Active 0 or x % SKIN CARE * A O/W emulsion with 5% IPD shows an immediate hydrating effect Ultrez 10 (carbomer) Lanette 16 (cetyl alcohol) Cithrol GMS (Glyceryl stearate/peg 100 stearate) Parrafin oil AAB2 (Paraffinum liquidum) 0.15% 1% 3% 3% Synergistic association with sorbitol (5%) lengthens the effect up to 2 hours Better results vs. traditional moisturizer Na hyaluronate (0.5%) TEA 0.6% Germaben II (PG, diazolinidyl urea, methyl-, propyl parabens) Deionised water 0.7% Bal. to 100% Study protocol: 5 volunteers application on forearm average value after 10 measurements made by corneometer *Studies performed by IRFAQ France
MOISTURISING EFFECT ON SKIN * Active 0 or x % Ultrez 10 (carbomer) 0.15% Lanette 16 (cetyl alcohol) Cithrol GMS (Glyceryl stearate/peg 100 stearate) Parrafin oil AAB2 (Paraffinum liquidum) 1% 3% 3% TEA 0.6% Germaben II (PG, diazolinidyl urea, methyl-, propyl parabens) 0.7% Deionised water Bal. to 100% *Studies performed by IRFAQ France
HAIR CARE * IPD provides repairing effects on damaged hair and satisfactory sensorial results in oil-based hair cleansers Effect on damaged hair: synergistic effect observed with sorbitol (ratio 1:1) in damaged hair treatment (aspect improved) Treatment with IPD & sorbitol (5%/5%) improves the smoothness of damaged hair vs.; IPD alone hydrolyzed proteins addition of glycols to sorbitol Smoothness effect is evaluated as hair sliding by drop height (ring test) & coefficient of static friction (sliding angle test) *Studies performed by IRFAQ France
HAIR CARE * Static friction: IPD & sorbitol protect hair shafts by closing cuticles IPD DPG BG PG Isopentyl diol Dipropylene glycol Butylene glycol Propylene glycol *Studies performed by IRFAQ France Caucasian hair locks supplied by Secher Fesnoux
HAIR CARE * Ring test: IPD & sorbitol protect hair shafts by closing cuticles 15 10 5 0 IPD DPG BG PG Isopentyl diol Dipropylene glycol Butylene glycol Propylene glycol *Studies performed by IRFAQ France Caucasian hair locks supplied by Secher Fesnoux
HAIR CARE * Repair effect clearly visible by SEM Untreated damaged hair Dipped for 30 minutes in a IPD/sorbitol solution (5% each) Shampoos: IPD has a good influence on the foam of cleansing systems & improves hair shine of oil-containing formulae Oil based shampoos containing IPD lead to better combing and softer feel on hair *Studies performed by IRFAQ France
MAKE-UP * IPD improves the sensorial performances of make-up products, without affecting their stability COMPACT POWDERS: use level 3-5% powders; 5-10% eye-shadows IPD allows to reduce the amount of binders (direct addition to the powders) IPD improves drop test challenge IPD improves shine and pick-up when added @ 5-6% LIPSTICK: use level 2-3% IPD improves performances of lipsticks: soft feel, sliding, shine, trace) IPD does not affect drop point (below 5%) CAST FOUNDATIONS: use level in poured products: 5-10% IPD improves the casting phase of too viscous foundations heated @ 80-85 C IPD thus improves the skin application performances: pick-up, spreading, sliding *Studies performed by Dr Luigi Rigano
MAKE-UP Remover * Evaluation & scoring by volunteers of 5 make-up remover solutions with 10% of various diols Pads impregnated with 1g of solution were applied 10 times to remove foundation & lipstick Make up remover based on IPD showed excellent performance at removing lipstick while leaving nice skin after feel *Studies performed by IRFAQ France

ALCOHOLIC PERFUMERY * Perfect miscibility with many fragrances & aromas (1/1) Adding 10% of IPD to a hydro-alcoholic solution containing 1% perfume maintains transparency and reduces alcohol level (from 30 to 20%) Preparation of milder body perfumes with a lower amount of alcohol and with no sticky skin feel is now possible ORAL CARE * IPD is suitable for use in standard & transparent toothpastes Easier introduction of aroma during manufacture (ratio 1/1) Better dispersion & quicker swelling of silica powders Improves foam quality Suggested amount in toothpastes: 5-10% *Studies performed by Dr Luigi Rigano
