About

A silicone-based surfactant that helps deliver ingredients into the skin while providing a smooth, silky feel.

PEG-24 Trisiloxane is an alkoxylated silicone surfactant used to improve the spreadability and skin feel of cosmetic formulations. Like other PEG-modified silicones, it balances the properties of silicone polymers with ethoxylation. Concerns exist regarding potential contamination with 1,4-dioxane, which is regulated in the EU, though modern manufacturing maintains levels well below safety limits. The ingredient is not specifically restricted under EU Regulation 1223/2009 but falls under general surfactant safety assessments for cosmetic use.
