For consumers, identifiable numbers of approved colorants and dyes are
very, very helpful! People who may be sensitive to colorants and dyes
often know exactly what they are sensitive to ... and if they see the
specific content, that helps! If you have listed precisely what you
include, that is excellent.
I've seen ppd termed both dye and colorant ... I suspect there is a
lot of confusion in the marketplace. In any case, it is good that you
offer a product that doesn't harm people. In respect to your colored
henna products, I try to ALWAYS distinguish in my posts and lectures
between colored henna and ppd black henna so manufacturers of harmless
products will not be impuned.
And, I never mind being corrected. I rely on a lot of sources for my
information, and its good for me to know when one of my sources is
incorrect!
