    Sorry but at this point I am speechless, not sure what to say any further for a supplier who has no idea what is being supplied to the customer. You cannot index the colors by looking at the shades.

    How could the supplier of the colorant not know this information?

    Colorants are one of the most highly regulated of all ingredients that go into a cosmetic. In the US the FDA actually has to certify all batches of most colorants. It may be different in the EU but typically the EU is even more strict than the US.

    It sounds like you need a new color supplier.

    Mr @perry our colorants have entered to our stock system another cosmetic firm which was bankrupted.So Noone knows about its regular documents where it is.
    So finally,İ have pigments and i want to name them by C.Index numbers.

    best regards Mr.Perry.

    by the way,thnx @Chemist77.

    your best bet is to send them off to an analytical lab for identification; individual dyes and pigments are chemically unique, and can easily be identified with the correct techniques

    @Perry cosmetic colour suppliers in Europe generally sell FDA-certified (F)D&C colours, or colours that meet requirements for European food regulations
