which preservative would you choose?
I need to choose a preservative for my shower gel formulation. I used DMDM H at the supplier’s recommendation, but this is a protector with restrictions. my confidence was damaged.
I have specified 2 different protectors, but I cannot understand what to decide according to. The pH range of my shower gel is 5.5-6.
I was caught between “ethylhexylglycerin & phenoxyethanol” and “dehydroacetic acid & benzoic acid” mixtures. What is important for selection other than price comparison? thanks…
