What normal PH for waterbase hair pomade

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.

  • pH of a lipstick? Or do you mean a water containing lipbalm (with a creamy consistence)?
    A waterfree product has no pH, so there's no pH to measure.
  • @Soory dont lipstick, google translate, waterbase hair pomade i meen.

    Ok, confusion solved. ;) I think it's best if you post the compete formula of the pomade. It's very hard to say anything without knowing more details.

    Typically, hair products have a lower pH...say 5.0 - 5.5.  
  • @Doreen, this is formula thats i work now:
    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%
    Preservative - 0,5%

    Product is good, but PH i meen dont good...
  • @Perry, so i and think that 7,5 is more than normal.
  • How are you measuring pH? pH of the water part or pH of final product?
  • Hi Perry ! And everybody !  Can anyone recomand a ph tester for cometics? l need to chekc ph for my moisturizer (with other then the strips) and a thicker hair product. 
  • @Dirtnap1 ;measure the pH of the final product.
  • What are you using to measure the pH? What temps? After cure or while still hot?
  • @ Dirtnap1, I change the finished product after cooling

    Hi Perry , I read in ' Pouchers cosmetics and perfume ' pH of hair products should be between 5.5 to 6.2  .

    @Aziz - I don't really agree with that advice.   Here's a good article looking at pH of hair and hair care products.
    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4158629/

    "There is no standardized value for the shampoo final pH, and this is not a mandatory issue. The pH value is not informed on the labels. As the hair fiber has a pH of 3.67, a pH closer to 3.67 has less possibility to increase the negative electric charge that normally involves the capillary fiber. To address the treatment of the scalp, shampoos must not have a pH higher than 5.5."
