  Preservative systems for skin creams

  Posted by Joanna_Nguyen on November 11, 2024 at 7:30 pm

  I’m currently making a daily skin cream, however I’m not sure if my preservative system is ok, I’m afraid it’s too much, please advise me. My formula is as follows:

  0.3% Caprylyl Glycol

  0.1% Butylated Hydroxytoluene

  0.1% Sodium Benzoate

  0.5% Phenoxyethanol

  BHT is not an antimicrobial preservative.

  What’s pH?

    Yes, since my formula has 0.5% resveratrol, 0.5% extract, I want a little BHT to stabilize the formula

    Also my desired pH would be around 5.5-6.0
