Cetrimonium chloride and viscosity
Hey,
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 🙂
Best regards,

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?
