How do I start my own body wash line?

I want to start my own body wash line and I just wanted to know how I would do that I want to personalize everything from the bottle to the smell to the tint.. If I wanted to work with a company that is all radu established how would I contact them

First come up with a rough theme to market your new product. Hire a chemist to design the wash and start selling it locally. I bet you will do great.
