Not many. Really not many. Here are some lists of who owns what. I’m intentionally omitting some of the other brands that are just nail polish like Essie (L’Oreal), or hair products, etc.
Lancome, L’Oreal, Shu Uemera, Urban Decay, It, Maybelline, NYX, The Body Shop
Bobbi Brown, Clinique, Estee Lauder, Mac, Smashbox, Tom Ford, Too Faced
Bare Minerals, Buxom, Integrate, MACquilAGE, NARS
Calvin Klein, Cover Girl, Rimmel
Revlon (owned by Elizabeth Arden?)
This is hardly a complete list. I got tired after an hour of arduous research at the feet of Google search (wink). Feel free to add in comments to this.
