    I had the same experience with Ceteareth-25, and I believe they must be similar. If you want to check if this is an emulsifiyer, try to make an emulsion with it in a regular way (put it in an oil phase and melt it then mix with hot water phase). Cetyl Alcohol won’t form an emulsion.

    What temp are you melting and combining the phases at? Bring to at least 82 c and mix well. Cet 20/25 likes to clump when water is added until mixed from my experience.

    I would contact your supplier and make sure it is what you ordered.
