  • Am I mixing ingredients properly?

    Hello,

    When I making shampoo, I start with water and then add water soluble ingredients one at a time. When I add these ingredients, I mix for 1 minute (at 600 rpm for a 200ml sample). Then I begin adding in the oil phase (surfactants) one at a time and also mix these for 1 minute each. That is until I get into adding PEG-150 distearate. I understand that this is not the best thickener, but my formula calls for it. Because they are flakes and need to be heated, I add them into the beaker and the heat the beaker until they melt. After which, I mix for 1 hour so as to let it cool down. I then add in fragrance, claims oils, and one last solubilizer before adding preservative. When I add these final ingredients during the cool down, I only mix them for 1 minute each, and I notice my hair is a little frizzy even though I’ve dropped the Sulfonate down from 13% to 10% still no significant improvement. Is it possible I’m overmixing the sulfonate and/or undermixing the OliveM300 in the cool down? My current actives are as follows.

    Alpha Olefin Sulfonate - 10%

    Decyl Glucoside - 2%

    PEG-150 Distearate - 2%

    OliveM 300 - 1%

    PQ10 - 0.5%

    PQ7 - 0.4%

    Any advice would be appreciated!

    If those levels of PQ’s arr of active material, then you’re using too much. Also, you need some emolliency (silicones are used for that).

      I have silicones in the paired conditioner. Wouldn’t it be redundant to add silicones to the shampoo? If not, do I need any extra suspending agents or should I just be able to add it in after cool down?

    Consumers want to feel also conditioning from the shampoo, so silicones are always welcome. You can check big brands’ hair products, and you’lk find silicones both in shampoo and conditioners. If you use ether silicones or microemulsions, you might not need a suspending agent, but for macro and flluid silicones, you do.
