  Azelaic acid 10% and urea 10%+

  Posted by Goldspice on August 5, 2023 at 2:16 pm

  Hi all,

  I am awaiting an initial meeting with a cosmetic manufacturer who I’m sure will answer this but I wondered if anyone on here can shed some light in the interim.

  Is there any reason a product can’t contain 10% azelaic acid and 10-20% urea? What if the product also had 10% lactic acid? The type of product would probably be something you’d apply 2-3 times a week as an intensive treatment.

  Basically - is there any way to make the above work with the right additional ingredients? Any glaring issues with pH’s, solubilities etc that would make it impossible to create?

  I’m not a chemist myself, but curious to know if it is possible to achieve prior to my meeting with the company.

  Thanks

  Mostly, that is just too much acid to be putting on a person’s face! Skin irritation could be a big issue. Also, Lactic acid works best below a pH of 4.0 whereas Azelaic acid works best at a pH of 4.9. So, adjusting the pH to a mid-point would just make both ingredients less effective.

  I wouldn’t recommend doing this.

    Thanks Perry 🙂 I was hoping for it to be a body product but it seems too much even for that. I’ll re-evaluate things, thank you
