  • Publication number: 20230097987
    Abstract: Solid pigment dispersions are described which are formulated to a paste consistency during grinding to reduce the pigment particle size and form a dry granular consistency at ambient temperature that is pourable and easy to handle. This allows for stronger, more intense colors and allows for easy integration into a variety cosmetic products. These pigment dispersions are prepared with plant-derived substances, derived from naturally occurring, renewable sources.

  • Publication number: 20100061951
    Abstract: A modified pigment that may include a polymer. The pigment may be directly attached to a nitrogen atom. The nitrogen atom may be attached directly or indirectly to a group that may include —S-Z. S may be a substituted or unsubstituted alkyl group, substituted or unsubstituted aromatic group, or polymer chain having a molecular weight range from about 300 to about 20000. Z may be a hydrogen, carboxyl, sulfonyl, phenolic, phosphoryl, ammonium, trimethylammonium, or tributylammonium group. Also, a modified pigment that may include a polymer. The pigment may be attached to an organic group through a carbon atom that is part of a N—C?N bond. A cosmetic formulation that may include a pigment covalently bonded to an organic group.
