| titleOfInvention | A kind of method of extracting chestnut husk brown pigment in chestnut shell and application in hair dye |
| abstract | The invention provides a method for extracting chestnut husk brown pigment from chestnut shells and its application in hair dyes. The extraction method comprises: adding powdered chestnut shells to an ethanol aqueous solution containing ionic liquid and a bond breaking agent, and ultrasonically extracting , after centrifugation, the supernatant was taken to obtain the chestnut husk brown pigment extract. The extraction method provided by the invention adopts the mixed solvent composed of ionic liquid known as green solvent and ethanol aqueous solution to replace the traditional extraction agent, adds a certain bond breaking agent, and is supplemented by ultrasonic technology. The extraction efficiency is high and the effect is good. After the hair dyeing agent prepared from the chestnut husk brown pigment extracted by the method provided by the present invention dyes the hair, the hair has no obvious fading behavior after repeated water washing and ultraviolet irradiation, and the hair scales on the surface of the hair are relatively flat, and there are few Lifting phenomenon, the damage to the internal structure of the hair is less, and the integrity of the hair is better maintained. |
