Problems solved by technology

Among carbon-based dyeing black materials, carbon black has good colorability and chemical stability, is safe, non-toxic and low in price, and is widely used in fields such as rubber, plastics and coatings, and has also been reported in hair dyes. The black particle size is small and easy to agglomerate, and the polar groups on the surface are less suitable for wetting, so the dispersion stability is poor. There are problems such as uneven coloring and insufficient color fastness when dyeing black hair with it. Most of them are only used in temporary hair dyes or As a dyeing aid
If it can solve the problems of uneven coloring and insufficient color fastness of carbon black hair dye, it can be regarded as an ideal permanent black hair dye colorant

Abstract

The invention discloses a hair dye for physically dyeing hair by utilizing plant extracts and natural pigments, which is prepared from raw materials such as mulberry leaves, natural carbon black, scutellaria baicalensis, Pu'er cooked tea, bletilla striata, scutellaria baicalensis, and Polygonum multiflorum. The invention also provides an application method of the hair dye. The hair dye of the present invention opens the hair scales through the extract of mulberry leaves, absorbs natural carbon black on the hair scales and sandwiches them between the hair scales, and then uses the extracts of Scutellaria baicalensis and Polygonum multiflorum to close the hair scales , so that the natural carbon black is firmly sandwiched within the hair scales, achieving the color fastness of chemical hair dyes, and the hair surface presents a glossy effect, resulting in a high brightness like fish scales, which will make the dyed black hair thick black shine. The hair dye of the present invention adopts raw materials from natural sources, does not contain chemical substances, is safe and non-toxic, does not hurt hair and scalp, and does not produce side effects on human health. It is good news for pregnant women, sick and infirm, and has good market application. prospect.

Description

technical field [0001] The invention relates to the technical field of daily chemical products, in particular to a hair dye and a preparation method for physically dyeing hair using plant extracts and natural pigments. Background technique [0002] With the gradual increase of silver-haired people and the change of people's aesthetic concept, the market demand for hair dyeing and color fixing products will increase day by day. With the continuous improvement of people's attention to health, chemically synthesized hair dyes contain carcinogenic and strong allergenic chemical dyeing ingredients (such as phenylenediamines, aminophenols, etc.) and some harmful ingredients (such as hydrogen peroxide, ammonia water, etc.) etc.), has received more and more attention. For this reason, people try to seek natural harmless, safer hair dyeing materials. For example, plant pigment hair dyes have achieved certain results, but there are still many problems. Such products still cannot avo...
