And probably jeapordize exisiting relationships already established. I certainly (from a relabeler's standpoint) wouldn't want to do business with a manufacturer who discloses this confidentail info with the public.
Remember, there's only a couple of manufacturers that pour wax in the country, but dozens of offerings. I know for a fact that many companies go the manufacturer and tell them to alter the color, fragrance and container & that is the only thing that makes it different. Yet I see so many people argue and praise how different they really are??
Also, do really think that a manufacturer that also retails their line would offer a "better" product to someone they make products for? Different yes, but maybe not superior. It's not like the client is the one coming up with the formula. They're just going with the best option offered to them per their specs.
