I don&#;t know where to start as this topic is endless, so l will stick to one product I have more experience with: foundations.

Foundations pigments are made of TiO2 and three iron oxides (yellow, red, and black). No consumer would be able to mix those three themselves to obtain their &#;perfect colour&#;. Ask an artist who paints portraits how long it took them to figure out how to mix human skin colour.

These pigments are not easy to mix. They must be treated (say with methicone) to mix with oil. You need the right type of oil. You need dispersing agents such as polyhydroxystearic acid and hectorites to make it work. You need special equipment (three roll mills etc) to make it work. It&#;s problem after problem after problem. You solve one, and another arises.

Also, foundations are mostly W/Si. W/Si are fussy structures. If your customer adds more of the pigment blend than that base could take, it will separate. If not right away it will do it in a week. If not in a week in a month. The customer won&#;t be happy.

To summarise, there is a lot to it. It&#;s not the same as mixing paint, unfortunately.
