Applications
UsesDiethyleneglycol Monolauryl Ether is a useful synthetic intermediate in the synthesis of quaternary ammonium salt cationic surfactants.
Useslaureth-2 is a surfactant and emulsifying ingredient. It is the polyethylene glycol ether of lauryl alcohol. Increasing the number of moles (laureth-3, laureth-7, and so on) usually makes the product milder.
