Phenylpropyldimethylsiloxysilicate

Phenylpropyldimethylsiloxysilicate (CAS 207692-01-1) is a silicone resin used in personal care formulations and industrial coating systems. It functions as a rheology modifier and surface-active agent.

This material controls texture, film formation, and substrate wetting across a range of formulated products. In color cosmetics and skincare, it improves the slip, spreadability, and long-wear performance.

It is frequently used in foundations, primers, and sunscreens by modifying the sensory profile of silicone-based formulations. Coating and adhesive formulators use it to adjust viscosity and enhance surface adhesion.

The resin is particularly effective on low-energy substrates. In sealant and elastomer systems, it contributes to film integrity and compatibility with other silicone components during the manufacturing process.

Polymer compounders may incorporate it as a surface modifier to improve interfacial bonding and processing behavior. This versatility makes it a staple in high-performance chemical manufacturing and design.

The product is typically supplied as a liquid or resin solution, often in a carrier solvent or blended with cyclopentasiloxane for cosmetic applications. Technical-grade material is the standard offering.

Industrial uses include coatings, adhesives, and polymer systems. Cosmetic-grade variants are available for personal care applications, with documentation suitable for regulatory compliance in those markets.
