WOW! I ground through it. I guess I must have skipped class the day we covered cosmetics grade units. Well, fair enough. I suspect it is obvious to anyone with any science background that such units are quite silly at best, but because the cosmetics industry is a common source for a material we have use for, and they choose to use silly units, then by golly, I guess we need to understand silly units. I am just that much smarter today! Thanks for the education!
