Difficulties in working with dispersed pigments
We’re working on some make-up formulations and found it difficult to incorporate pigments (the supplier sent them previously dispersed)
We tried to incorporate it into the oily phase, but the result wasn’t good… the pigment doesn’t seem to be completely incorporated and several “dots” and traces of color remains (we heat the oily phase separately from the aqueous one, mix the pigment in the oily phase and, when both are at 75 ºC, we pour one over the other, proceeding with stirring at 500-800 RPM)
We also tried to incorporate it into the cooling process and, although the color was more beautiful, we still noticed the dots (in this case, we make the entire emulsion, heating the oil and aqueous phases to 75 ºC and then stirring at 800 RPM. When it cools down, we add the dispersed pigments and stir up to 1000 RPM)
We’ve already tested it on a serum (fluid, low oily phase, low coverage) and on a sunscreen (more viscous, higher oily phase, medium coverage), without success
Is there any technique that facilitates the incorporation of these dispersed pigments? It’s our first time working with this type of formulation
Thank you for your time (:
