CETYL DIGLYCERYL TRIS(TRIMETHYLSILOXY)SILYLETHYL DIMETHICONE.

Valuable CAS 1466529-58-7 / EMULSION STABILISING, SURFACTANT - CLEANSING

A high-performance, branched silicone emulsifier engineered to create sophisticated water-in-oil textures without the use of PEG-based chemicals. It provides a unique, breathable moisture barrier that stabilizes complex mineral sunscreens and pigments while maintaining an exceptionally light, non-tacky finish.

Emulsion Stabilizing Surfactant Pigment Dispersant Skin Conditioning

Science

This multi-functional molecule utilizes a branched architecture featuring a diglycerol hydrophilic head and cetyl lipophilic chains. By significantly lowering interfacial tension, it facilitates the creation of stable emulsions and prevents the agglomeration of inorganic UV filters like Zinc Oxide, while simultaneously forming a non-occlusive, hydrophobic film that reduces transepidermal water loss.

As a primary functional emulsifier and stabilizer, this ingredient is rarely 'dusted' because its physical presence is required for the formula's structural integrity. Concentrations below 0.2% would likely fail to provide the necessary dispersion for mineral pigments or UV filters.

Stability

Exhibits excellent stability across a broad pH range; however, structural integrity is maximized when the internal water phase is fortified with electrolytes like Magnesium Sulfate or Sodium Chloride (0.5-2.0%).
