Mechanism of Action
Functioning as an amphiphilic compound, PEG/PPG-12/35 Copolymer reduces surface tension to facilitate the uniform dispersion of immiscible liquids, forming stable emulsions. This mechanism ensures product stability and enhances texture. Its capacity as a viscosity control agent further refines formulation rheology, potentially contributing to a light, silky, and cool skin feel. Related polymer classes also suggest roles in film formation and humectancy, aiding in moisture retention and the solubilization of oily components within water-based systems.

Stability
Due to its polyethylene glycol component and nonionic surfactant nature, PEG/PPG-12/35 Copolymer exhibits solubility in both water and alcohol. Its amphiphilic properties are ideal for stabilizing emulsions by effectively interacting with both aqueous and oil phases. Related polymers within this class are generally stable and effective across a wide pH range.
Safety
Safety Profile
While PEG/PPG-12/35 Copolymer lacks a dedicated CIR report, it is classified within the 'Polyoxyalkylene Siloxane Copolymers' category, which the CIR generally considers safe. Clinical studies on similar ingredients, such as Dimethicone Copolyol, indicated non-irritating and non-sensitizing properties. However, general discussions exist regarding potential immunogenic reactions associated with PEGs due to widespread exposure, though this is not specifically highlighted for this copolymer at typical cosmetic concentrations.
