Abstract: A hair darkening dye composition, comprises: 2-98 parts by weight of hair dye; 1-99 parts by weight of darkening agent; 2-98 parts by weight of crosslinking agent; 2-98 parts by weight of emulsifier; 2-98 parts by weight of dyeing auxiliaries; and 0.1-40 parts by weight of pH regulator. The darkening agent is selected from one or more of chitin, chitosan, gelatin, silicon oil and resin. The chitin, chitosan and gelatin have a relative molecular weight of less than 2.7×104, and the silicon oil and resin have a refractive index of less than 1.55.

Abstract: The present invention discloses a color-enhancing detergent for colored textile and a preparation method therefor. The color enhancing detergent for colored textile is composed of the following raw materials in parts by weight: a detergent, a deepening agent, a penetrating agent, a cationic modifier, a fiber modifier, a cellosolve, a diffusing agent, a dye fixing agent, a leveling agent, a dyeing auxiliary, a brightening agent, a bleaching agent, a pH-adjusting agent, and a bluing agent. The detergent can effectively fix the color of the colored textile that is washed and can deepen the original color as well.
