Valuable CAS 27306-78-1 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING, SURFACTANT - FOAM BOOSTING

PEG-8 TRISILOXANE is a multifaceted silicone derivative engineered to enhance both skin texture and formulation stability. It acts as an effective skin conditioning agent and emollient, promoting soft, smooth skin, while also facilitating the stable emulsification of oil and water components in cosmetic products.

Summary

Skin Conditioning Emollient Cleansing Agent Emulsifier Surfactant - Foam Boosting

Science

Mechanism of Action

This ingredient functions primarily as a skin conditioning agent and emollient, contributing to a smoother and softer skin feel. Its silicone structure provides a notably low surface tension, which enables excellent spreading qualities and allows for the formation of a lightweight, vapor-permeable protective film on the skin's surface. Additionally, PEG-8 TRISILOXANE serves as a surfactant, crucial for cleansing, emulsifying, and boosting foam production, thereby aiding in the stable integration of disparate phases within formulations.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) panel has determined PEG-8 TRISILOXANE to be safe as used in cosmetics. However, manufacturers are advised to ensure that levels of potential impurities, specifically ethylene oxide (below 5 ppm) and 1,4-dioxane (below 1 ppm), are minimized during the production of polyethylene glycols (PEGs). While not typically sensitizing to normal skin, components like PEG-8 have been associated with mild immediate hypersensitivity and contact dermatitis in individuals with compromised or damaged skin, such as burn patients, due to increased absorption. It is generally permitted as a food additive.
