  • Help with hair volume on shampoo & Preservative

    Posted by kannes on October 1, 2022 at 1:45 am

    I’ve made a shampoo bar recently.  It has really nice suds, cleans really nice without feeling drying, it’s smoothing and leaves a really nice shine to hair.  It formed a really nice hard bar.  It performs almost exactly as I wanted it to except one thing…hair volume feels a little less than average, just a little bit flatter/limper than I wanted.  Is there something I can adjust to bump up the volume a little without drying out hair?

    I wanted to get a working formula before I add a preservative.  If there are any specific preservatives that you think might be more compatible with this formula, any suggestions would be greatly appreciated.  Thanks so much for your time!  

    Sodium cocoyl isethionate (powder form) 50%
    Sodium Lauryl Sulfoacetate 17%
    Cocamidopropyl Betaine 10%
    BTMS 25 6%
    cetyl alcohol 4%
    stearic acid 2.5%
    hydrolyzed rice extract 2%
    *Repair Vita Oil 2%
    polyquaternium 7  1.5%
    panthenol 1.5%
    sodium lactate (60%) 1.5%
    artichoke leaf extract 1%
    brassica oil copolymer 0.5%
    mango seed butter 0.5%

    * Repair Vita Oil contains sunflower seed oil, macadamia seed oil, quinoa seed extract, coconut oil, gardenia flower extract, rosemary leaf extract and tocopherol.

    I have a moisture analyzer.  Testing a finished bar that’s hardened for a week says it has 3.06 % moisture content.

    @kellymila The Behentrimonium in your BTMS could potentially react with one of your anionics, forming an insolue compound that deposits on hair and weighs it down. Could you try one sample wothout BTMS?
