  • Molar ratio of cationic surfactant: fatty alcohol for best conditioning effect

    Posted by Abdullah on May 17, 2022 at 8:05 am

    What molar ratio of cationic surfactant: cetearyl alcohol gives best conditioning effect for hair?

    If cationic surfactant is Behentrimonium chloride or Behenamidopropyl dimethylamine

    @Pharma there are some informations that show adding fatty alcohol improves combing. 

    Like this chart about Behenamidopropyl dimethylamine. 
    It shows 1% BAPDMA+ 3% fatty alcohol has almost the same combing force reduction as 2% BAPDMA+ 2% fatty alcohol.
    Any comments on this?

    Pharma said:

    Conditioning is mainly done by the cationics whilst fatty alcohols give the creamy consistancy (the more fatty alcohol, the higher viscosity).
    Aim for a whole numbered ratio between 1:1 and 1:6 (at least, that’s what the science behind it dictates -> in cosmetics, always regard theory with caution and prove it right or wrong by trial and error).

    Got it
    Thanks
