Hey look, Lead in Lipstick, Genius, but you guys aren't a one trick pony, (I'll leave you two to argue which of you is the head, and which is the butt in this metaphorical pony suit. :P) I believe to reallllly wet people's willys would be another book! Maybe explaining the latin on the back of their products, and how they work with the other chemicals. I think this would be a desirable index to anyone who genuinely wants to know more about they are buying, or people who want a desk reference for when they're making cosmetics. You guys, not only have the knowledge, but the skillset to do it. You know like a for dummies cosmetics chemicals index.
If that doesn't work you can always sell sexy calendars on Amazon.
