摘要：
PIGMENTS ARE USED TO IMPART COLOR IN FINISHED PRODUCTS. THE PERFORMANCES OF PIGMENTS CAN BE IMPROVED BY COATING WITH SUITABLE MATERIALS RENDERING SUITABLE PROPERTIES. FOR COSMETIC APPLICATIONS THE PIGMENTS ARE USUALLY SURFACE TREATED WITH HYDROPHOBIZING MATERIAL RENDERING THE PIGMENTS HYDROPHOBIC. THIS INVENTION RELATES TO THE USE OF POLYHYDROXY FATTY ACID PRELERABLY DIHYDROXYSTEADC ACID (DHSA) AND/OR METALLIC SALTS OF DIHYDROXYSTEARIC ACID (METALLIC DHSA) TO COAT PIGMENTS IN PARTICULAR PIGMENTS TO BE USED IN COLOR COSMETIC FORMULATIONS. DHSA IS PRODUCED EITHER FROM CRUDE OR REFINED OLEIC ACID OR VIA CHEMICAL TRANSFORMATION OR BIOTRANSRORMATION OF SUITABLE SUBSTRATES, USED EITHER IN CRUDE OR REFINED FROM AND THE METALLIC SALTS ARE PRODUCED EITHER USING CRUDE OR REFINED DHSA. DHSA AND METALLIC DHSA ARE USED TO COAT PIGMENTS AND WHEN THESE COATED PIGMENIS ARE INCORPORATED INTO FINISHED PRODUCTS FORMULATIONS SUCH AS COSMETIC FORMULATIONS, ENHANCED PERFORMANCES ARE OBSERVED. IN COLOR COSMETICS THE ENHANCED PERFORMANCES INCLUDE ENHANCING SKIN ADHESION, BETTER SPREADABILITY, INCREASING STRENGTH OF THE STICK, INCREASING APPARENT SIZE AND INCREASED HYDROPHOBICITY OF MAKE-UP COSMETICS SUCH AS LIPSTICKS, FOUNDATIONS, MASCARAS, EYE SHADOWS ETC.
