Common Name(s): Peg/ppg-modified silicone,water-soluble silicone,hydrophilic silicone emulsifier

CAS Number: N/a

DESCRIPTION

What It Does: Delivers silicone conditioning (smooth skin feel, low friction, water resistance) in water-based formulations where pure dimethicone is incompatible โ€” providing the sensory benefits of silicone with aqueous phase compatibility.

Why It's Used: Peg/ppg silicones bridge the incompatibility between dimethicone and aqueous formulations โ€” the grafted peg/ppg chains provide sufficient water affinity for aqueous dispersion while the si-o backbone provides the characteristic silicone sensory benefits.

How It Works: Peg or ppg chains grafted onto the silicone backbone via si-o-chโ‚‚ linkages provide hydrophilicity (hlb increases with peg chain length). the amphiphilic structure enables self-emulsification and aqueous dispersion while the polydimethylsiloxane backbone provides low surface energy (20 mn/m) for smooth skin glide.

SCIENTIFIC NOTE

Peg-modified silicone hlb varies from 3 (short peg, w/o) to 15 (long peg, o/w) โ€” the peg chain length selection determines whether the ingredient functions as a w/o co-emulsifier or o/w emulsifier/solubiliser.
