DIISOSTEAROYL TRIMETHYLOLPROPANE SILOXY SILICATE.

Valuable / SKIN CONDITIONING

Diisostearoyl trimethylolpropane siloxy silicate is a silicone polymer that forms a water-resistant film on the skin, effectively preserving moisture and preventing dryness. It acts as an emollient, enhancing skin hydration, while providing uniform spreadability and a lubricating feel. This ingredient also extends the wear of makeup and protective creams by forming a long-lasting, hydrating layer.

Skin conditioning Emollient Film-forming

Science

This silicone polymer functions by creating a water-resistant film on the skin's surface, which acts as a barrier to minimize moisture loss and combat dryness. It delivers emollient properties, contributing to enhanced skin hydration, and ensures a smooth, uniform application with a noticeable lubricating sensation. Furthermore, its film-forming capability extends the longevity of cosmetic and protective formulations by maintaining a hydrated interface.

Conflicts

  • Requires careful formulation to ensure the final product is non-irritating.
  • For products with potential incidental inhalation, the raw material must contain less than 0.1% crystalline silica, or repeated-dose inhalation studies are required if crystalline silica is 0.1% or greater to confirm no adverse effects.
  • Insufficient safety data currently exists, thus use in airbrush formulations should be avoided.

Safety

CIR Status
Safe with restrictions
Sensitization risk Low

The CIR Expert Panel considers surface-modified siloxysilicates, including this ingredient, safe for cosmetic use when not expected to be incidentally inhaled and when formulated to be non-irritating. For products that may lead to incidental inhalation, safety is contingent on crystalline silica content being below 0.1% in the raw material, or on demonstrated safety via repeated-dose inhalation studies if crystalline silica is 0.1% or higher. Data remains insufficient for determining safety in airbrush applications. EWG Skin Deep rates common concerns such as cancer, allergies & immunotoxicity, developmental and reproductive toxicity, and use restrictions as 'LOW'.
