    good morning 
    i want to ask you if any one have an idea about how can we add the formaldehyde in a solution of prepared keratine mix at the end and which percentage can i use. because i have already prepared mixes and i want to add formaldehyde to it.
    thank you

    In my country I don’t think it is legal to use formaldehyde. It is a known carcinogen.

    … and formaldehyde-free formulations don’t work nearly as well.

    That’s why using a formaldehyde donor like DMDM Hydantoin, Imidazolidinyl Urea, or Diazolidinyl Urea can work.

    Do formaldehyde donors pass regulations for free formaldehyde (after being left standing for a while so enough formaldehyde has been released)?

    It’s legal at 0.1% as a preservative, not as an active ingredient.
