  Fragrance selection and testing in hair straighteners

  Posted by Cafe33 on November 24, 2024 at 2:25 pm

  What key factors should I consider when selecting and testing fragrances for use in a hair straightening cream that will be exposed to heat during application? Specifically, how can I evaluate their thermal stability and compatibility with active ingredients? Would testing on a mannequin head with 100% human hair help in anyway ?

  pH of cream is <2.0

  Thanks in advance
