Science
Mechanism of Action
This ingredient functions by creating a lightweight, protective film on the skin's surface, a characteristic of silicone polymers. This film contributes to moisture retention by reducing transepidermal water loss and provides lubrication, thereby improving the skin's feel and facilitating the smooth application and spread of formulations. It is expected to act as a skin and hair conditioning agent, an emollient, and potentially a co-emulsifier, contributing to formulation stability and aesthetic properties.

Stability
As a PEG-modified silicone, DIMETHICONE PEG-7 UNDECYLENATE is characterized by its water-dispersibility, which allows for easy removal and prevents undesirable buildup on skin or hair. It is generally considered straightforward to formulate into various cosmetic systems.
Safety
Safety Profile
While a specific Cosmetic Ingredient Review (CIR) report detailing DIMETHICONE PEG-7 UNDECYLENATE was not identified, the broader class of Dimethicone and related substituted-methicone polymers, including PEG-modified dimethicones, has been extensively evaluated. The CIR Expert Panel concluded these ingredients are safe for use in cosmetic products, noting their large molecular weight makes significant skin absorption unlikely. Dimethicone is also recognized by the FDA as an approved skin protectant, and regulatory bodies like the FDA and European Commission deem PEG-Dimethicone derivatives safe within recommended concentrations.
