Home Cosmetic Science Talk Formulating IPBC usage rate in combination with phenoxyethanol or DMDM hydantoin

  • IPBC usage rate in combination with phenoxyethanol or DMDM hydantoin

    Posted by abdullah on January 15, 2022 at 1:52 pm
    IPBC has recently gained my attention as a fungicide because it is effective at very small amount.

    My questions is
    How much IPBC+phenoxyethanol or IPBC+ DMDM hydantoin is a good starting point for preserving lotion and also how much for shampoo?

    ~100 ppm.  Benzoate prob better for shampoos.

    @PhilGeis 100ppm is the upper limit. Should i use this amount even when combined with phenoxyethanol or DMDM hydantoin?
