  • Hair wax (solid stick format) does not solidify completely in the bottom part

    Posted by jonathan02 on July 10, 2024 at 9:28 am

    Hello everyone. I am trying to make a hair wax packaged in a deodorant push up stick. so my goal to make a very solid formulation.

    this is my formulation

    CCT

    Beeswax

    Sunflower Oil

    Jojoba Oil

    Coconut Oil

    Polysorbate-80

    Cocoa Butter

    Cetyl Alcohol

    BTMS-50

    Candelilla Wax

    Vitamin E Oil

    But after using it, I observe the bottom part is relatively “liquidy” as compared to the top part. What causes this? It looks like liquids are settling at the bottom part? I am bothered that it is not as homogeneous as possible. Is it because the bottom part is not exposed with air?

    Hello,

    I have experience in formulating anhydrous formula with polysorbate inside.

    I assume that liquid at the bottom of the stick is polysorbate-80.

    Based on my previous experience, polysorbate can’t completely miscible with oil phase and will precipitate since it has higher density than the oil.

    May i know why you add polysorbate in your hair wax formulation? I think you don’t need to add polysorbate. Usually i add polysorbate in anhydrous formulation such as cleansing balm or stick as a surfactant/cleanser. But in hair wax, you don’t need surfactant inside.

      Thank you for the insight. I put polysorbate 80 to make it easily washable in the hair after. Is there anything i can put in place of polysorbate 80 to make it easy to wash off?

    Chances are some oils and waxes are not compatible (different polarity can impact miscibility when mixed), so you better check that before. A non-ionic surfactant like the polysorbate you have is more useful when there’s water present, because it acts better in a protic media.

      Ohhh. That’s something that i have never known before. Can you give me an example of this so I can understand it better? But thank you so much, will definitely be looking into this
