Request SDS →This material is a powder blend of polycaprylylsilsesquioxane (a crosslinked silicone resin) and alumina (aluminum oxide, CAS 1344-28-1). The alumina component functions as an opacifying, texturizing, and viscosity-controlling powder in cosmetic and personal-care formulations.
Frequently Asked Questions
What is polycaprylylsilsesquioxane and alumina used for?
It is a powder blend used in cosmetic and personal-care formulations as an opacifier, texturizer, and viscosity/rheology modifier. The alumina component provides opacity while the crosslinked silicone resin modifies feel and spreadability.
What does the alumina component do in this blend?
Aluminum oxide (alumina, CAS 1344-28-1) functions as an opacifying and texturizing powder and helps control viscosity in formulated bases. It is commonly used in color cosmetics and decorative product systems.
What is the function of the silsesquioxane resin in the blend?
Polycaprylylsilsesquioxane is a crosslinked silicone resin that contributes to film, texture, and spreadability of the powder phase. It pairs with the alumina to deliver combined opacity and feel benefits in formulations.
What is the CAS number for the alumina in this product?
The alumina (aluminum oxide) component carries CAS 1344-28-1 and formula Al2O3. Reference this CAS together with the full blend name on any CoA or SDS request to confirm composition.
How is this powder blend supplied in bulk and what handling documentation is available?
It is supplied as a dry powder blend in standard industrial packaging for formulators. Request the SDS and CoA for GHS classification, particle/handling data, and lot specifications before ordering; pricing is available by bulk quote.
