Science

Mechanism of Action

On the skin, PEG/PPG-16/17 Copolymer functions as an effective cleansing agent and surfactant, gently lifting impurities. Its amphiphilic structure enables it to emulsify immiscible substances, such as oil and water, creating stable product formulations. Furthermore, it acts as a humectant, actively drawing and binding moisture to the skin to enhance hydration. As a solvent and solubilizer, particularly its water-soluble polypropylene glycol components, it aids in dispersing and incorporating other ingredients. Certain PEG types within its structure are also known to facilitate the enhanced penetration of co-formulated active ingredients into the skin.

Not reviewed
Sensitization risk Low

While PEG/PPG-16/17 Copolymer itself has not undergone a specific CIR safety assessment in the provided data, related PEGs and PPGs are generally recognized for their very good skin tolerance. These compounds typically induce minimal to no ocular or dermal irritation, possess extremely low acute and chronic toxicities, and exhibit negligible penetration of intact skin. Their sensitizing potential on healthy skin is considered very low. However, it is noted that a closely analogous compound, PEG/PPG-17/6 copolymer, has been highlighted as requiring further safety study.
