Hi friends, at the moment I am working on how much and lipstick formulas for hair, and I have a question what is the normal pH level for lipstick. I get 7.5, is this normal? Or is it necessary to lower? In confusion. I would be grateful for any help. Thank you in advance.
Comments
A waterfree product has no pH, so there's no pH to measure.
Ok, confusion solved.
Water - 64%
Cetearet 25 - 20%
Polysorbate 80 - 2%
Propylenglicole - 2%
Vegetable glycerine - 2%
PVP k30 - 4%
PEG 40 - 4%
Color - 1%
Scent - 1%
Scent fixatore - 0,5%
