    There’s some stuff that I sometimes notice in my daily life as a cosmetic formulator, and I would like to bring some of them to discuss here sometimes.

    So, one thing that I noticed is that sometimes Cetrimonium Chloride decreases the viscosity of conditioners. Has anyone noticed this too? What is the concentration range (%) that you normally use at conditioners and hair masks formulations? 

    Thanks in advance 🙂

    Yes, it can do that since it is a cationic surfactant and will interact with charged micelles and other electrolytes. But it could also increase viscosity depending on what else is in the formula.  The conditioner I worked on, we used ~0.5 - 1% cetrimonium chloride.  Hair masks are just thickened conditioners so you can use the same level for those.

    @Perry 1% cetrimonium chloride which is 0.3% cationic surfactant?

    Was there another silicone or cationic surfactant in this product?
