Q1: What is the primary function of DOWSIL EP-9610 in cosmetic formulations?
A: DOWSIL EP-9610 is a hydrophobic silicone-based powder designed to enhance sensory properties—delivering a soft, silky, non-greasy skin feel—while improving powder cohesion, blendability, and oil absorption in makeup and skincare products.
Q2: Is DOWSIL EP-9610 compatible with common cosmetic actives and preservatives?
A: Yes, it demonstrates broad compatibility with typical cosmetic ingredients including UV filters, vitamins, peptides, and conventional preservative systems. However, compatibility testing under final formulation conditions—including pH, temperature, and shear—is recommended to confirm stability and performance.
Q3: How should DOWSIL EP-9610 be incorporated into formulations?
A: It is typically added during the dry-blending stage for powders or dispersed into the oil phase for emulsions. For optimal dispersion, gentle mechanical mixing or high-shear processing may be used depending on the base system and desired particle distribution.
Q4: Does DOWSIL EP-9610 impact the SPF performance of sunscreen formulations?
A: While not an active UV filter, DOWSIL EP-9610 does not interfere with the photostability or efficacy of common organic and inorganic UV filters when properly formulated. Its inclusion may support even film formation and reduce whitening, but SPF validation must be conducted on the final product.
Q5: What are the recommended storage conditions for DOWSIL EP-9610?
A: Store in a cool, dry place away from direct sunlight and sources of heat or moisture. Keep containers tightly sealed to prevent humidity uptake and maintain optimal flow and dispersibility characteristics.
