Q1: What is the primary function of DOWSIL 9702 in formulations?
A: DOWSIL 9702 is a free-flowing silicone elastomer powder designed to provide soft-touch feel, improved slip, reduced tack, and enhanced surface smoothness in personal care and cosmetic formulations—especially in powders, sticks, and anhydrous systems.
Q2: Is DOWSIL 9702 compatible with common cosmetic actives and pigments?
A: Yes, DOWSIL 9702 demonstrates broad compatibility with typical cosmetic ingredients including metal oxides (e.g., titanium dioxide, zinc oxide), organic pigments, emollients, and waxes. It is generally stable in non-aqueous, low-polarity systems but may require evaluation in highly polar or reactive environments.
Q3: How is DOWSIL 9702 typically incorporated into formulations?
A: It is commonly added during the dry-blending stage for powder-based products or dispersed via high-shear mixing in molten wax/oil phases for solid stick formats. Pre-blending with a portion of the base powder or carrier oil helps ensure uniform distribution and prevents agglomeration.
Q4: Does DOWSIL 9702 affect the stability or shelf life of finished products?
A: When properly formulated and stored under recommended conditions, DOWSIL 9702 contributes to long-term physical stability by reducing particle cohesion and minimizing phase separation in anhydrous systems. Its inert silicone nature supports oxidative and thermal stability in typical cosmetic use conditions.
Q5: Can DOWSIL 9702 be used in rinse-off applications?
A: While primarily optimized for leave-on and anhydrous formats, DOWSIL 9702 can be included in rinse-off products where temporary sensory benefits are desired—however, its impact will be transient due to rapid removal during rinsing, and performance should be verified in final product testing.
