  • Question about a Garnier brand shampoo bar with oils in it (with photos! 🤩)

    Posted by Margaret on November 21, 2023 at 5:31 pm

    I recently bought a Garnier brand shampoo bar because I figured its pH is probably WRONG, since there is NO mention of a pH adjusting ingredient. PLUS I wanted to test its lather since it has oils in it.

    Yes, I only have pH sticks, yes I know they are not good, but they are “good enough for rock ‘n roll” and for my amateur purposes. ANYhow….

    The Garnier bar is around pH 6.5. The photo does not quite show the colors of the bands accurately.

    The photo of the 2 bowls of water show what the water looked like after I washed my hands of the shampoo bars, after I tested the lather, out of curiosity:

    The CLEAR rinse water on the LEFT is of a shampoo bar made with 89% surfactants and ZILCHO oils/butters. In case you’re wondering, its pH is around 5.

    The CLOUDY rinse water on the RIGHT is the gross-smelling Garnier shampoo bar.

    1) Could the Garnier rinse water be cloudy because of the oils they use? They have added hydrogenated vegetable oil, caprylic/capric triglycerides and the tiny amounts of the marketing claim ingredient oils.

    2) Is the following a fair guess for the % of the first 3 ingredients?:

    - sodium cocoyl isethionate 41%

    - hydrogenated vegetable oil 9% (it might be Cegesoft HF 62)

    - sodium coco-sulfate 8%

    I came up with the above %s by looking at 22 different formulae from manufacturers and suppliers of cosmetic ingredients. I looked at the few formulae that had the same 2 surfactants AND oils (various types) and looked at those formulae ingredient ranges for an idea of what Garnier might be using, roughly. I cannot find the MSDS for the Garnier shampoo bars from which I could get a rough idea of ingredient %s, for my morbid curiousity.

    Thanks for your thoughts!

    If the turbid solution settles over time in the bottom (precipitation), that might be the coacervate that has formed upon dilution.
