We are using cosmetic ingredients all the time, but often have to buy in more than we need for the projects we are working on. Rather than throw them away we offer them for sale, sometimes at much lower prices than other suppliers.
We don't get stuff in that isn't any good, so you can be sure that these raw materials are the right level of quality for formulating with. Indeed we control our raw materials following the principles of cosmetic Good Manufacturing Practice (cGMP) as laid down in the international standard ISO 22716. So everything is fully traceable and suitable for any cosmetic manufacturing purpose.
Just remember that we don't always have stock of everything on our list.
