  • Salt Spray - Separation

    Hello, 

    I have recently tried formulating a salt spray but I noticed separation once it started cooling down. 

    The ingredients are:

    Water
    Amodimethicone
    Trideceth-12
    Cetrimonium Chloride
    Magnesium Sulfate - 3%
    Cetearyl Alcohol 
    Polysorbate 60
    Sodium Chloride - 0.2%
    Citric Acid 
    Phenoxyethanol 

    I mixed the salts in the water and then heated it to 75-80 deg C before adding
    Amodimethicone
    Trideceth-12
    Cetrimonium Chloride
    Magnesium Sulfate
    Cetearyl Alcohol 
    Polysorbate 60

    It was stable until I turned off the heat. White chunks started forming and floating on top. 

    Did I not heat it enough? Was there too much salt? 

    Any advice would be appreciated! 

    Thank you!

    @Cosmetic_Chemist Can you try one sample without salts? Some emulsions don’t tolerate high amounts of electrolytes.
