Preservatives Which Can Itch

Preservatives are a common source of skin irritation or allergic reaction in cosmetics and hair products. This is a short list of common offenders to suspect if a product causes problems for you:

Benzyl alcohol
Imidazolidinyl urea
Diazolidinyl urea
Sodium Hydroxylmethylglycinate
Methyl, Propyl, Butyl, and Ethyl Parabens
DMDM hydantoin
Methylisothiazolinone©Science-y Hair Blog 2013

Those in italics are formaldehyde releasers. Formaldehyde is an excellent preservative, but can be commonly irritating to skin and is dangerous to breathe (carcinogenic).©Science-y Hair Blog 2013

  1. Benzyl alcohol is a popular one, I think that may explain why I am not able to use some popular conditioners as leave-ins e.g. Tressemme Naturals.
