Octyldodeceth-10 (inci)

Octyl dodecether(s)" are the polyoxyethylene ethers of octyl dodecanol (for comparison see: laurethe as polyoxyethylene ether of lauryl alcohol; steareth as polyoxyethylene ether of stearyl alcohol, etc.). In the name of octyldodecethes, the inserted numbering means the average number of ethylene oxide units per mole. Octyldodeceth -10 is the INCI designation for a polyoxyethylene ether with 10 ethylene oxide units per mol.

Octyldodeceth-10 is used in cosmetic formulations. The substance acts as surfactant (washing-active substance) and as emulsifier (changes the interfacial tension of liquids like water and oil so that they can be mixed together).
