Bubble-formulation hair dye and preparation method thereof

Abstract

The invention relates to a bubble-formulation hair dye and a preparation method thereof. The hair dye consists of two components, namely a component A and a component B. The component A consists of a dye mixture, a surfactant, a film forming agent, an alkalizer, water-soluble lanoline, water-soluble silicone oil, a humectant, an antioxidant, a heavy metal chelating agent and an essence and is prepared by the following steps of: adding water with the temperature between 45 and 55 DEG C to the film forming agent, and stirring for dissolution; adding the alkalizer, the water-soluble lanoline, the water-soluble silicone oil, the humectant, the antioxidant, the heavy metal chelating agent and the dye mixture, and stirring for dissolution; and finally adding the surfactant and the essence, stirring for dissolution, and filtering the mixture. The component B consists of hydrogen dioxide and phosphoric acid and is prepared by the following steps of: adding the hydrogen dioxide into water, and stirring for dissolution; adjusting the pH value to between 2 and 4 by using the phosphoric acid; and filtering the mixture to discharge the material. The hair dye is characterized in that: the production process is simple; the hair dye has the bubble formulation, is easy to spread uniformly and has good hair dyeing effect; and a user can optionally change the colour of the hair at home.

AI Technical Summary

Problems solved by technology

Paste hair dye contains a lot of salt in the formula, which will reduce the stability of the paste, and there is a danger of emulsion separation. In order to avoid separation, the viscosity must be increased, so it is difficult to apply evenly, and a brush must be used. It is difficult for hair dyers to operate by themselves, and it is difficult to rinse off after use, so it is necessary to wash hair with shampoo after dyeing hair; hair dye shampoo is more convenient to operate than hair dye cream, but it has a fatal disadvantage, it needs to add water when dyeing hair In this way, the amount of water added cannot be controlled, resulting in the uncontrollable content of intermediates in the final hair dyeing, and there will be deviations in the dyed color; propellants need to be added during the production of hair dyed mousse, the production process is more complicated, and there are certain limitations in use and storage. It is dangerous and not environmentally friendly; it is easier to inhale dust when using hair dye powder, which will cause harm to the human body, etc.
