Ceteareth-2
What Ceteareth-2 is & what it does
Ceteareth-2 is a polyethylene glycol ether of cetearyl alcohol with a low degree of ethoxylation (2 units). It is commonly used as an emulsifier and surfactant that helps blend oil and water phases, and its low ethoxylation gives it an oil-loving, co-emulsifier character. It is typically paired with higher-ethoxylated partners to build stable emulsions in creams and lotions. It is a functional formulation ingredient rather than a skincare active.
