  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?

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