Phenylpropyldimethylsiloxysilicate

Phenylpropyldimethylsiloxysilicate (CAS 207692-01-1) is a silicone resin for personal care formulations and industrial coating systems.

Where is Phenylpropyldimethylsiloxysilicate used?

• Color cosmetics and skincare: improves slip, spreadability and long-wear performance
• Foundations, primers and sunscreens: modifies the sensory profile of silicone-based formulations
• Coatings and adhesives: adjusts viscosity and enhances surface adhesion, particularly on low-energy substrates
• Sealants and elastomers: contributes to film integrity and compatibility with other silicone components
• Polymer compounding: surface modifier for interfacial bonding and processing behaviour
• It functions as a rheology modifier and surface-active agent.

Good to know: Cosmetic-grade variants come with documentation suitable for regulatory compliance in those markets.

Commercial specifications

• Liquid or resin solution, often in a carrier solvent or blended with cyclopentasiloxane for cosmetic applications
