Lactic Acid
Is anyone aware of lactic acid being used as an exfoliant rather than a pH adjuster in shampoo? We’re looking at a water soluble formula good for fine hair: water, ammonium laurel sulfate, cocamidopropyl betaine, jojoba seed oil, hydrolyzed milk protein, mucopolysaccharides, biotin, lactic acid, polyquat 10, cocomide mea, glycol stearate, polysorbate 20, tetrasodium edta, citric acid, ammonium chloride, DMDM hydantoin
Would not the citric acid be sufficient?

- Yes. -
Thanks. The inclusion is throwing me. It might be possible that it’s serving as an emollient, but the chance of exfoliation of the cuticle worries me

Lactic acid is not used for exfoliation as I really doubt the hair or scalp would need exfoliation. My guess is that actic acid is part of one of the blends.
Use citric acid to adjust your pH. It’s more than effective. -
My guess would be that either they’re using the lactic acid as their pH adjuster and the citric acid is coming in as part of a pre-blended raw material, or vice-versa. If you’re buying each component seperately, you should be fine with using just citric acid.

My guess is that they are including the Lactic Acid as a multifunctional to (1) Adjust the pH and (2) Lactic Acid will strip the outer keratin layer to make hair softer and more manageable. Is this a general purpose shampoo is it a shampoo targeted at people who have thick, hard to manage hair?

Thanks for the replies. It would be targeted for general use, which is what caused my concern.

Sorry to revisit this subject, but at a pH of 4.5-5.5 (which is what we would want) would the lactic acid work only as an emollient and not act as an exfoliant?

It’s there as a pH adjuster without much other benefit.
