Valuable CAS - / HAIR CONDITIONING, HUMECTANT, SKIN CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG/PPG-23/23 Butyl Ether Dimethicone is a versatile silicone copolymer designed to enhance skin feel and formulation stability. This multi-functional ingredient acts as an emollient, humectant, and emulsifier, contributing to skin conditioning and optimizing product texture. It effectively forms a protective film on the skin's surface.

Summary

Emollient Emulsifying Skin-Conditioning Humectant Surfactant Hair Conditioning Agent

Science

Mechanism of Action

This ingredient operates by forming a protective, yet non-occlusive, film on the skin, which contributes to its conditioning and emollient properties. As a humectant, it actively attracts and binds water, thereby boosting skin hydration. Furthermore, it functions as a surfactant and emulsifying agent, helping to stabilize formulations by depressing surface tension and ensuring uniform dispersion of diverse components.

Key findings

  1. 01 Clinical evaluations conducted on the broader class of Dimethicone Copolyol, which includes PEG/PPG-23/23 BUTYL ETHER DIMETHICONE, consistently demonstrate a low potential for skin irritation and sensitization.
  2. 02 Specifically, a 40% aqueous solution of Dimethicone Copolyol was identified as a non-primary skin irritant.
  3. 03 Further testing of undiluted Dimethicone Copolyol, alongside an unspecified concentration in a study involving 201 volunteers, confirmed its nonirritating and nonsensitizing characteristics.
