PERFLUOROOCTYLETHYL TRISILOXANE

Description

Perfluorooctylethyl trisiloxane is a synthetic silicone-based compound widely used in cosmetic and skincare formulations. This multifunctional ingredient serves as an emollient, lubricant, and water-repellent agent, contributing to improved product texture and performance.

The molecule consists of a perfluorinated carbon chain attached to a trisiloxane backbone, resulting in unique physicochemical properties. Its low surface tension allows for smooth application and even distribution on the skin, while its film-forming capabilities help create a protective barrier. This barrier function aids in reducing transepidermal water loss and enhancing skin hydration.

Perfluorooctylethyl trisiloxane is particularly valued in long-wearing makeup formulations, sunscreens, and water-resistant products due to its ability to impart water repellency and improve product adherence to the skin. It also functions as a carrier for other active ingredients, potentially enhancing their delivery and efficacy.

While generally considered safe for cosmetic use, ongoing research examines its environmental impact and potential bioaccumulation. Formulators often use this ingredient in concentrations ranging from 0.1% to 5%, depending on the desired product attributes and regulatory guidelines.
