Science
Mechanism of Action
This ingredient operates by forming a surface film on the skin, providing conditioning benefits and a smooth feel without penetrating the epidermal layers. As a surfactant, it effectively depresses surface tension, serving as an emulsifier to blend oil and water phases, a wetting agent, and a lubricant in formulations. It also contributes to emulsion stability and can enhance the efficacy of biocides.

The Formula
Formulation
Stability
Compositions incorporating PEG/PPG-22/22 Butyl Ether Dimethicone demonstrate robust stability across a wide spectrum of pH levels and temperature variations. Its hydrophilic polysiloxane structure, due to PEG moieties, facilitates solubility in both water and alcohols, with water solubility increasing with a higher number of alkoxy groups.
Safety
Safety Profile
The broader category of 'dimethicone copolyol', which encompasses PEG/PPG-22/22 Butyl Ether Dimethicone, was affirmed as 'safe as used' by the CIR Expert Panel in 1982 and reaffirmed in 2005. However, the 2014 CIR report noted a specific lack of reported usage concentrations in the VCRP for this particular ingredient, prompting a request for more specific data. No dedicated SCCS opinion or specific FDA regulatory status beyond VCRP reporting was identified.
