Is it necessary to wear mask or special glasses when working with formalin?
I am currently trying to shift to using formalin as preservative for my shampoos because of it’s effectiveness, no impact on viscosity and very affordable price. I will go to DMDM hydantoin in the future.
The shampoo is made cold process.
I currently wear no mask or glass when making samples in a small closed room or during manufacturing in a big room and kind of open because i didn’t feel the need for it. I have worked with only phenoxyethanol, benzyl alcohol and fragrance as volatile ingredients.
Yesterday i purchased some formalin and did smell it from close , it was very unpleasant and disturbing for my eyes and nose but two of my colleagues who didn’t try to smell it from that close felt nothing whe filled one bottle from another bottle of formalin.
My question is
is it safe to work with formalin in closed room for making samples or big and open room for production without wearing mask or special glasses?
