How, when and why do formaldehyde donors release formaldehyde?
Suppose DMDM hydantoin for example in a Shampoo formula. It has formaldehyde but it is not free at first.
Here are some questions.
1. Does it releases the Formaldehyde by Time? For example release specific percentage each month until all of them are released?
2. Does it release formaldehyde when it is needed? For example if it gets contaminated it releases some formaldehyde to kill the microbes and if didn’t get contaminated don’t release formaldehyde too?
3. Or it has any other plan on when to do or don’t release formaldehyde?
