  • Cetearyl Alcohol + Cetrimonium Chloride => The harder Emulsifier

    Hair conditioner!
    .
    Hi all,
    When emulsifying the Cetearyl Alcohol (4%) in water, it’s diluted.
    However, when adding 1.5% Cetrimonium Chloride (still having 4% Cetearul Alcohol), it’s harder.
    I can’t know why it’s so magical! Is there reaction between them?
    Can you tell my why?
    Thanks for all!
    Best regard!

    Not enough ingredients to create a stable formula. See the following 3 examples with Cetrimonium Chloride

    What do you mean by “it’s harder”?  Do you mean that it is thicker?  Do you mean that it is more opaque?

    The answer comes down to the microscopic structure of the particles in the solution. It’s not a chemical reaction between them, it is a physical arrangement of the molecules.

    This isn’t exactly the components of your system but this phase diagram demonstrates some of the different structures that happen at different concentrations of surfactant/water/oil. Each of those different structures will affect the viscosity / clarity of your system.
