PEG-10 NONAFLUOROHEXYL DIMETHICONE COPOLYMER.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING

PEG-10 Nonafluorohexyl Dimethicone Copolymer is a silicone derivative prized for its skin and hair conditioning capabilities. It forms a breathable film on the skin's surface, promoting moisture retention and enhancing product aesthetics and spreadability. This ingredient also exhibits surfactant properties, contributing to its versatility in various cosmetic formulations.

Skin Conditioning Hair Conditioning Emollient Film-forming Skin Protectant Emulsifier Surface Tension Reducer

Science

Mechanism of Action

This copolymer operates by creating a lightweight, permeable film on the skin, which conditions, lubricates, and protects while allowing vital oxygen and nutrient exchange. Its substantial molecular structure prevents significant absorption, acting as a surface-level skin protectant. It effectively binds water, minimizing transepidermal water loss, and imparts a luxurious, silky feel. Beyond moisture retention and enhanced spreadability, it can offer a subtle optical effect, visually minimizing the appearance of fine lines and pores for a smoother, more radiant skin impression. Its ability to decrease water's surface tension further highlights its surfactant characteristics.
