BIS(PPG-7 UNDECENETH-21) DIMETHICONE.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A sophisticated polyether-modified silicone designed to bridge the gap between aqueous and lipid phases in high-performance emulsions. It serves as an amphiphilic conditioning agent that optimizes product spreadability while imparting a weightless, silky finish to the skin's surface.

Summary

Skin Conditioning Emulsion Stabilizer Sensory Modifier Surfactant Emollient

Science

Mechanism of Action

This large-molecule polymer anchors to the skin's surface to create a breathable, non-occlusive barrier that prevents moisture loss. Its unique structure, featuring both hydrophilic PPG/Undeceneth chains and a lipophilic dimethicone core, allows it to stabilize complex formulations while providing immediate tactile smoothness and reducing surface friction.

Key findings

  1. 01 Demonstrated significant enhancement in pigment distribution and texture silkiness in SPF and foundation matrices (US Patent 10,137,073).
  2. 02 Proven to reduce surface friction and improve tactile combability without traditional polymer buildup in topical applications (WO 2010/149798).

Because it is often utilized as a functional co-emulsifier rather than a standalone active, it is rarely 'dusted' for marketing purposes. In precision skincare, levels below 0.1% are generally insufficient to provide the characteristic sensory and stabilization benefits.
