Oleth(s)" are the polyoxyethylene ethers of oleyl alcohol, an unsaturated monohydric alcohol with the linear formula CH3(CH2)7CH= CH(CH2)7CH2OH (for comparison see: laurethe as polyoxyethylene ether of lauryl alcohol; stearethe as polyoxyethylene ether of stearyl alcohol, etc.). In the term "oleth", the numbering shown below indicates the average number of ethylene oxide units per mole. For oleth-50 this is 50 ethylene oxide units per mole.

Oleth-50 is used in cosmetic formulations. The polyoxyethylene ether acts as a surfactant (washing-active substance) and cleansing agent (cleans the body surface).
