I always thought that alcohol denat. stood for denatured alcohol. For example, in the perfume industry, the two main ingredients are the fragrance (usually essential oils) and alcohol denat. You'll probably also have a few more ingredients that are supposed to keep the scent on longer. Anyway, Denatured Alcohol is just ethanol that is denatured so you get sick when you drink it. It is cheaper to use vodka which is not denatured ethanol in these perfumes but it is illegal. Yeah that was always my take on it, not sure what it does on hair though... I'd like to know I apologize if any of this info is wrong.
It's extremely drying. Any product I've used on my hair with alcohol denat. in it has left my hair a frizzy, dry mess. Just earlier this evening I found an old tube of Garnier gel that I cast aside after 2 uses resulting in dry hair, I looked at the ingredients to see what's in there, and it smacked me in the face: ALCOHOL DENAT.
