C10-18 Triglycerides Polyglyceryl-3 Esters Phosphates

A sophisticated hybrid emulsifier that combines biomimetic C10-18 triglycerides with polyglyceryl phosphate technology to create stable, skin-friendly formulations. This multifunctional ingredient melts at skin temperature for enhanced sensory properties while providing superior emulsion stability compared to traditional emulsifiers. Its dual anionic-nonionic nature makes it particularly valuable for PEG-free clean beauty formulations.

Science

Mechanism of Action

Functions as a hybrid emulsifier where the C10-18 triglyceride backbone provides skin-mimetic emolliency with a 36°C melting point for optimal absorption, while the polyglyceryl-3 phosphate group creates electrostatic stabilization through anionic charge distribution, resulting in robust emulsions that resist destabilization from electrolytes and active ingredients.
