  • Sodium cocoyl question

    Posted by Roberto on September 20, 2018 at 12:31 am

    I had cooled off my oils to 50 degrees and my sodium cocoyl which i have melted with water and have cooled off to 50 degrees (I have mixed 1 part of sodium to 3 part of water)

    After the final mixing and pouring in the mold after 24 hours later my Bar shampoo 
    isn’t getting hard enough, not as hard as i had expected.

    What seems to be the problem?
    Thanks for any feed back.

    If you want advice you’re going to have to list the entire formula.

    There are a number of problems here.
    1. This is not a shampoo bar formula - It seems like half of a soap formulation (with no sodium hydroxide) with some mysterious “sodium cocoyl” ingredient added.
    2. What is the full name of the “Sodium Cocoyl” you are using? There are many ingredients starting with “Sodium Cocoyl”. Sodium Cocoyl Isethionate? Sodium Cocoyl Glutamate? Sodium Cocoyl Sulfosuccinate?
    3. What are you trying to create here? A soap bar for washing hair or a syndet shampoo bar?
    I would recommend joining swiftcraftymonkey’s website for some good starting formulations (https://swiftcraftymonkey.blog) for shampoo bars.

    Your bar isn’t getting hard enough because the oils and sodium cocoyl isethionate are liquid at room temperature. You can’t substitute a surfactant for the lye and expect a saponification reaction to happen.
