Light sensitivity of formalin & DMDM hydantoin in shampoo with transparent package
Posted by Abdullah on August 3, 2022 at 3:32 amDoes light exposure reduce the efficacy of formalin or DMDM hydantoin in shampoo that has a transparent package and no UV absorber?

I have not seen this in practice & have tested numerous shampoos/conditioners that are exactly as you describe

I tested a few formulas using formalin but the vast majority were DMDM Hydantoin
