Yep.
I guess my point I am not making very well is: to the comment of what we've seen here at tPF being reactions to the photoinitiators - is that the allergies are actually most commonly to the acrylates. Almost all the nail products we're talking about have some type of acrylate. (If it's true Shellac has none at all, then this makes sense why people can wear it.)
What we do know: acrylates are reactives to which we are exposed during the curing process. They are highly common allergens. They are in many types of plastics and glues but once hardened no longer give off the allergens. If you under-cure you are therefore increasing your exposure.
If it's true that no photointiators are acrylates, then it also follows that the allergies we've seen here are most likely not to photoinitiators. We've conjectured alot back in the beginning. (I only use the words most likely since people can be allergic to just about anything).
I just went thru the Gelish Base ingredients as an example (cause it has the least, lol!) and the only ingredient that isn't an acrylate or doesn't turn into one when compounded is Hydroxycyclohexylphenyl Ketone. (Oh and there is a dye). That last one is indeed an organic photoinitiator. Whether it's the only one, I'm not sure. So to your other point, you may be correct and I may have just proved my hunch totally wrong about photointiators also inclduing some acrylates. I for sure just found at least one that is not.
So I've worn myself out on that one. If I'm still not making sense, then I will just have to live with that.
- is there's lots we don't know. So it's not always knowledge. But we learn more and more as go.
