PEG/PPG/BUTYLENE/DIMETHICONE COPOLYMER.

Valuable / FILM FORMING

This multi-functional silicone copolymer forms a breathable film on the skin's surface, effectively reducing transepidermal water loss to maintain optimal hydration. It also functions as a conditioning agent, enhancing skin smoothness and improving the aesthetic feel and stability of cosmetic formulations.

Science

Mechanism of Action

PEG/PPG/BUTYLENE/DIMETHICONE COPOLYMER operates by creating a protective, vapor-permeable film across the skin's surface. This polymeric layer significantly diminishes transepidermal water loss (TEWL), thereby preserving moisture and promoting a smooth, supple skin texture. Beyond its hydrating properties, it lubricates the skin, offering a protective shield against environmental stressors, irritants, and microbes. In product formulations, it serves as a conditioning agent and a co-emulsifier, adept at stabilizing challenging oil and water mixtures, particularly water-in-silicone emulsions, while improving spreadability and imparting a silky, non-greasy finish.

Stability

The incorporation of PEG and PPG groups into dimethicone significantly boosts its water-solubility by introducing polarity. This characteristic enables it to effectively bridge and stabilize oil and water phases, making it particularly useful for forming and stabilizing water-in-silicone emulsions.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed dimethicone copolyols, a category that includes PEG/PPG Dimethicone variants, concluding they are safe for use in cosmetics. A primary concern is the potential presence of 1,4-dioxane, a possible human carcinogen, as a byproduct of the ethoxylation process; therefore, rigorous filtration during manufacturing is imperative to mitigate this risk. This ingredient is approved for 'EWG VERIFIED' products, albeit with restrictions and warnings, particularly for inhalable product forms due to potential respiratory concerns or if toxic impurities are present. While specific maximum concentrations for this exact copolymer were not explicitly found, related PEGylated oils have been deemed safe at concentrations up to 100%.
