  • Is this formula mild enough as a baby wash

    Posted by Abdullah on March 1, 2023 at 9:01 pm

    I am trying to make a baby Shampoo that is gentle for babies skin and also cleans and foams will.

    As i cant test it on babies i have to ask here if this formula is mild enough.

    Ingredients in active

    SLES 5%

    Disodium laureth sulfosuccinate 2.5%

    CAPB 0.5%

    Cationic guar 0.2%

    Glyceryl Oleate 0.2%

    Xanthan gum 0.2%

    EDTA 0.1%

    Nacl 5.5%

    Fragrance 0.005

    CMI MI 3ppm

    Formaldehyde as formalin 74ppm


    pH is 6

    Anionics: CAPB ratio 14:1

    Is this formula mild enough as a baby wash Product?

    I wouldn’t use CMI/MIT in a baby product. Plus, Formaldehyde is already banned in cosmetics (formaldehyde donors can still be used). I wouldn’t use that much NaCl either (if you increase CAPB you’d get higher viscosity without using that much salt, and would also make your product milder).

      Can you tell me why you don’t like that mach nacl?

      What is the side effect of that much or even higher nacl?

      During use the Product gets diluted at least 10 times and it will be less than 1% nacl during application.

    When you have charged molecules, increasing ionic strenght of your system (like adding high levels of an inorganic salt) could be a risk for stability over time. Perhaps in your system it could work, but I prefer to reduce the risk as much as possible.

      Is this the amount of nacl that increases the risk of instability or it’s ratio with total surfactants?

      For example in a liquid foam wash with 2.7% total surfactants i use 1.8% nacl. The ratio nacl: surfactant is 1:1.5 in both formulas.

      Will this also have such chance of instability even it has low nacl but high compared to amount of surfactant?

      And what type of testing will predect such instability?

    It’s the contribution of all ionic species, but mostly of the inorganic salts. You could check instability by placing a sample in the fridge for at least 1 month.

      What temperature minimum?

      Is 0°c enough?

    The usual (2-5°C).
