Extraction method of carrot pigment and natural hair dye containing carrot pigment

Abstract

The invention relates to an extraction method of a carrot pigment and a natural hair dye containing the carrot pigment. The extraction method of the carrot pigment comprises the following steps of putting a cleaned and impurity-removed carrot in an agitator for crushing, then adding the crushed carrot into absolute ethyl alcohol for leaching to obtain leaching liquor, filtering and centrifuging the leaching liquor, and taking supernatant liquor for evaporating and concentrating, so as to obtain the carrot pigment. The natural hair dye comprises the following raw materials in parts by weight: an agent A: containing 0.1 to 10 parts of the carrot pigment, 10 to 30 parts of polyhydric alcohol, 1 to 10 parts of surfactant, 1 to 5 parts of thickening agent and 45 to 87.9 parts of water; an agent B: containing 0.5 to 5 parts of metal mordant, 1 to 10 parts of surfactant, 1 to 5 parts of thickening agent and 80 to 97.5 parts of water. All the raw materials in the agent A and the agent B are mixed and uniformly agitated respectively; a pH (potential of Hydrogen) value is regulated to be 5 to 7, so that the natural hair dye containing the carrot pigment can be obtained. According to the extraction method of the carrot pigment and the natural hair dye containing the carrot pigment, the raw materials are easily obtained; a process is simple; the cost is low; the operation is easy; a dyeing effect is natural and lasting.

Description
