  • Where to find Ceteareth-25 and PVP/VA Copolymer in Portugal?

    Posted by Jorge on March 8, 2024 at 6:05 am

    Hello, chemist.

    I am currently involved in a project to develop a series of clear water based hair waxes. Thanks to the invaluable inputs of professional formulators here in the forum (I am a pharmacist with limited experience in cosmetic formulating), I was able to achieve the desired consistency, texture and transparency but the hold is lacking. Here is the basic formula:

    Water: 51%

    Ceteareth-20: 30%

    Propylene glycol: 8%

    Glycerol: 7%

    Polysorbate 20: 2%

    PVP: 2%

    I tried increasing PVP level but it makes the gel more opaque and doesn´t increase the hold that much.

    In almost all the beanchmarks, I see that the most used ingredient (besides water) is Ceteareth-25 but I can´t find any supplier in Portugal.

    Would appreciate any help you can provide or tips about substitutions.

    Thank you.

    @Jorge Brenntag should be distributing all over the Iberian Peninsula. They feature BASF and SABO, two manufacturers of ceteareth-25.

    No luck dealing with Brenntag. I am considering ordering from China via Alibaba. Any recommendation?
