Science
Mechanism of Action
This ingredient functions by significantly reducing the surface tension between immiscible liquids, acting as an effective emulsifier to create and stabilize oil-in-water systems within cosmetic formulations. Beyond its crucial role in formulation stability, Polyglyceryl-6 Tristearate is anticipated to contribute to skin conditioning, promoting a softer and smoother skin feel. It supports the skin's natural moisture balance and helps reinforce its protective barrier, which can mitigate the impact of environmental stressors. Drawing parallels to related polyglyceryl esters, it may also enhance the penetration of active ingredients into the deeper skin layers and reduce the perception of oiliness on the skin.

Stability
As a polyglycerin fatty acid ester, Polyglyceryl-6 Tristearate demonstrates robust stability with excellent resistance to both salts and acids. It effectively functions as an oil-in-water emulsifier, forming stable emulsions whose optimal performance is influenced by its concentration and the overall compositional synergy of the formulation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Polyglyceryl-6 Tristearate, alongside 273 other polyglyceryl fatty acid esters, is safe for use in cosmetics under current practices and concentrations, provided that the finished formulations are non-irritating. A specific maximum concentration for Polyglyceryl-6 Tristearate was not designated, but the entire group was deemed safe as used.
