Abstract
The present invention solves the problem of providing a method for stabilizing a solid pigment. The problem is solved by a method for stabilizing at least one solid pigment selected from the group consisting of solid carotenoid pigments and solid curcumin pigments, the method comprising the step of mixing the solid pigment with a lipophilic liquid in an amount of 200 parts by mass or less per 100 parts by mass of the solid pigment.

A method for stabilizing at least one solid pigment selected from the group consisting of solid carotenoid pigments and solid curcumin pigments,
- the method comprising the step of mixing the solid pigment with a lipophilic liquid in an amount of 200 parts by mass or less per 100 parts by mass of the solid pigment.
A pigment preparation comprising at least one solid pigment selected from the group consisting of solid carotenoid pigments and solid curcumin pigments,
- the preparation comprising a lipophilic liquid in an amount of 200 parts by mass or less per 100 parts by mass of the solid pigment.
A method for producing a pigment preparation comprising at least one solid pigment selected from the group consisting of solid carotenoid pigments and solid curcumin pigments,
- the method comprising the step of mixing the solid pigment with a lipophilic liquid in an amount of 200 parts by mass or less per 100 parts by mass of the solid carotenoid pigment.
A coated hydrophobic solid particle comprising
- (1) a hydrophobic solid particle and
- (2) a coating layer directly coating the hydrophobic solid particle, the coating layer comprising a lipophilic liquid and no gas.
