PEG-22/DODECYL GLYCOL COPOLYMER
PEG-22/DODECYL GLYCOL COPOLYMER is a synthetic polymer made of polyoxyethylene chains joined to dodecanediol units. In the INCI name, “PEG-22” refers to an average number of ethylene oxide units along the chain, so it does not describe one single molecule with a fixed size.
PEG-22/DODECYL GLYCOL COPOLYMER: what it is
PEG-22/DODECYL GLYCOL COPOLYMER is a synthetic polymer made of polyoxyethylene chains joined to dodecanediol units. In the INCI name, “PEG-22” refers to an average number of ethylene oxide units along the chain, so it does not describe one single molecule with a fixed size.
The available chemical description also gives an average proportion between ethylene oxide and dodecanediol units. That arrangement brings together a portion that interacts more readily with water and another with a more oil-like character, which helps explain its place in preparations that need different components to stay evenly dispersed.
PEG-22/DODECYL GLYCOL COPOLYMER: what it does in cosmetics
In cosmetics, PEG-22/DODECYL GLYCOL COPOLYMER is an emulsifying surfactant. In practical terms, it helps water and oily components remain mixed, supporting a more even look and texture in a cream, lotion, or another product made from two phases.
It is also classified as a light stabilizer: its purpose is to help the formulation resist deterioration caused by light exposure, not to act as a sunscreen on the skin. This describes an expected role in the product itself; it does not by itself show a treatment, moisturising, or skin-protection effect.
PEG-22/DODECYL GLYCOL COPOLYMER: conditions and care
Clinical reports have linked PEG-22/dodecyl glycol copolymers in creams to allergic contact dermatitis. They do not establish frequency or general risk; if a product causes a reaction, stop using it and seek professional advice.
