So I'm sick of paying through the nose for wrinkle creams and I want to make my own. If I come up with something good, then maybe I can manufacture it and sell it to others.
How should I go about doing this?
Does anyone know of any good reference materials on the topic?
If a product label says 'green tea extract', how do you know what extraction method was used (aqueous, alcoholic, something else)? Does that mean it is the whole extract or might it have been fractionated (meaning they are really using a specific substance and you don't know what it is, except that it is a component of green tea extract).
