20220287939 · 2022-09-15 · ·

The present specification discloses a agent composition for modifying a pigment to dye that imparts tinting strength to the pigment, and a colorant composition in which a pigment is modified to dye using the same. According to the present disclosure, since the pigment has tinting strength on the skin, it is possible to realize various colors of the pigment as it is while having excellent durability when applied to the skin. Accordingly, the pigment may be comprised as a coloring agent in a cosmetic formulation requiring coloring by replacing the dye having a limitation in type and color when used in a cosmetic composition due to a stability problem for the skin. In addition, since the coloring agent according to the present disclosure has an irreversibly stabilized form, it can be widely used without being limited to the pH, formulation, etc. of the cosmetic composition.
