Pigment Dispersion in BB Cream
I am developing BB Cream in that I am using Iron oxide pigments.
I read so many literature and connected with so many supplier like sensient, Merck, Radian,Neelikol, Keol, etc for the pigment dispersion in cream.
everybody are telling that by mixing method we can disperse and use it that trial I have done but each and every trials with different emollients pigments are separating.
than some supplier told me that you have to use coated like pigment with dimethicone coated, coated with silane that also I used but still no result separation are there.
Some supplier are told me that you have to use pre dispersed (paste form) pigments - that also I have tried but still I am in the same page -separation.
Can anybody help that how can I develop a BB cream without pigment separation in the cream.
