Ceteareth-23
What Ceteareth-23 is & what it does
Ceteareth-23 is a polyethylene glycol ether of cetearyl alcohol, made by ethoxylating fatty alcohols. It functions mainly as a nonionic emulsifier and surfactant, helping oil and water phases blend into stable creams and lotions, and it can also act as a solubilizer. It is widely used across emulsions, including sunscreen bases, for a smooth uniform texture. It is not a UV filter itself and carries no concerns flagged here.
