Science
Mechanism of Action
This ingredient acts as a dual-function component, serving as both an emollient and a surfactant. As an emollient, it conditions the skin by imparting softness and smoothness, thereby promoting skin health. Its emulsifying capability allows it to stabilize oil-in-water mixtures by reducing surface tension, forming fine, uniform emulsions. The sunflower oil portion naturally provides antioxidant and anti-inflammatory benefits through its Vitamin E content, offering protection against environmental stressors. Additionally, its rich linoleic acid profile contributes to its lightweight texture and ready absorption, while lecithin supports the skin's natural barrier.

Stability
Polyglycerol esters generally exhibit robust thermal stability and good resistance to acids and salts. However, their ester linkage makes them susceptible to accelerated hydrolysis in the presence of strong acids or bases. Degradation by lipases is also a potential concern.
Safety
Safety Profile
The CIR Expert Panel has deemed polyglyceryl fatty acid esters, the chemical class to which this ingredient belongs, safe for cosmetic applications at current usage levels, provided formulations are non-irritating. These esters are recognized for being biodegradable, biocompatible, non-carcinogenic, and non-toxic. Safety assessments showed no adverse effects, even when tested at a concentration of 5 weight percent.
