1 Sun Protection Boosting Performance with Multi-Functional Technology

2 How to Achieve Maximum SPF in Sun Care Formulations? Good Spreadability Incorporation of Film-Formers Complete Solubilization of Crystalline Sunfilters Boosting the Dielectric Constant Inolex has several products to address these performance issues.

3 Solubility & Spreadability LexFeel 7 Ultra-dry, fast spreading emollient ensures even coverage Less greasy than typical sunscreen emollients Solubilizes more sunscreen than C12-15 alkyl benzoate LexSolv A Super-solubilizer to prevent recrystallization of UVA filters Safe, effective, globally approved

6 Benefits of Film Formers Creating an even film of UV protection For products to be efficient/effective they must evenly coat the rough topography of the skin. Creating a thicker film (increased path length for photons) Simply by doubling the film thickness you get up to 100X the protection against UV rays! Increasing Water/Wear Resistance

8 Lexorez 100 & Key Features Leading polyester polymers used in sunscreens to provide waterproofing and water resistance. They are 100% active liquid and are dispersible in organic UV absorbers and emollients. They can also be used in color cosmetics with SPF (lipsticks, mascara, foundations) to provided transfer resistance. Use level ~ 3% Patented Inolex technology

14 Maximize UV Filter Efficiency and Photostability by Boosting Dielectric Constant Organic UV absorbers convert the sun s radiation into electronic excitation energy. Excitation energy has several possible outlets: Destructive e.g., isomerization, bimolecular reactions Non-Destructive e.g., heat, fluorescence, energy transfer Materials with a high dielectric constant tend to promote nondestructive pathways and lead to: More photostable formulas Increased SPF values
