A functional stabilizer. Safe.
PEG-45/Dodecyl Glycol Copolymer is a copolymer that works as a stabiliser and co-emulsifier. In creams and lotions it keeps the formula homogeneous, helps bind the phases and improves the final texture. It is a technical support ingredient, not a headliner. This is a functional formula component, not a skincare active. Its role is product stability and feel, not treating skin. It does not moisturise or correct on its own. It delivers exactly what is asked of it: a stable emulsion and a uniform feel. Applied topically it has no systemic relevance, so it can be used during pregnancy and breastfeeding. Tolerability is good, with low irritation and allergy potential. It suits sensitive skin. Because it is used in modest amounts and serves a structural function, it is rarely the cause of a skin reaction.
