Description

Pigment composition for dyeing hair, blackening hair and nourishing hair and application thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a pigment composition for dyeing hair, blackening hair and nourishing hair and application thereof.

Background

Hair dyes are a common cosmetic in people's lives and are a necessity for changing the color of people. Worldwide, hair dyeing is an increasingly important activity, and the number of people using hair dyes in hairdressers, hair salons and at home is rapidly increasing. However, the nature of the chemical dyes in hair dyes presents potential health risks to the user. Most of hair dyes in the market at present use p-phenylenediamine (PPD) or a derivative of PPD as a main component. PPD itself has strong sensitization and can cause cross-sensitization with other various substances [ e.g., azo, aniline, local anesthetics (procaine, benzocaine), sulfonamide, etc. ]. PPD is also readily absorbed transdermally, causing damage to the gastrointestinal tract, nervous system, renal failure, distortion, carcinogenesis, and damage to the immune system. In addition, PPD hair dye is an oxidative hair dye, and the treatment of hydrogen peroxide destroys the original proteins and amino acids, so that dyed hair becomes dry, shiny and elastic, and hair are irreversibly damaged. Therefore, the development of a substitute product for dyeing hair and a method for applying the same, which are nontoxic and cancerogenic, can protect hair, and can reduce the potential harm to human health to the greatest extent.

Although some plant anthocyanin hair dyes have been reported in patent publications or marketed today, JPH04119179a discloses a specific anthocyanin compound, anthocyanin 3-peanut glycoside, in combination with quercetin glucuronide for dyeing wool. Furthermore, this patent relates to dyeing of fibers, in particular made of silk and wool, and requires dyeing conditions of ph2.5 in combination with a temperature of 95 ℃ for 1 hour, which is completely unsuitable for dyeing hair. Although it is suggested to use it as a dye, the technology does not mention the use of the material on hair, or indeed in any cosmetic application.

Chinese patent publication No. CN 101164528A uses plant pigment catechin as melanin precursor, and under the action of ferrous salt, the plant pigment catechin complex forms black on hair, so as to achieve the purpose of blackening. The same principle is adopted in chinese patent publication No. CN 1923164a, so that polyphenol substances in the pericarpium Granati are combined with a metal chelating agent to form a tan complex. US patent 4801302 discloses a method of dyeing hair using hematoxylin and copper salt hair dyes. The hair dye mentioned in the above patent does not have the damage to scalp caused by p-phenylenediamine, hydroquinone and the like, but has the defects that firstly, the adsorption is weak, and even if the complex is formed in the chelation process of the polyphenol substance and the metal ions, the complex is only adhered to the surface of the hair, and does not have strong adsorption effect with the hair, so that the hair dye is extremely easy to fade.

However, the defects of the plant hair dye are still not overcome in the actual hair dyeing process. It is difficult to achieve the desired effect by using a mixture of various agents once, and thus, all of them are required to be applied and washed twice or three times or more, which results in a rather complicated operation process, a dyeing time of up to 2.5 hours or more, poor permeability, easy discoloration, and most of the semi-permanent hair dyes, which directly affect the dyeing effect of the hair dyes, and consumer acceptance is not high.

The surfactant is fatty acid methyl ester ethoxylate sodium sulfonate, decyl sulfobetaine and lauroyl amphoacetate with the weight ratio of (0.3-0.9) 1 to (1-5).

Because the system of the invention contains complex plant extracts and simulated melanin precursors, the lipophilic and hydrophilic components are all present in the system, so that the stability of the system is poor, and the problem of the stability of the composition at normal temperature can be well solved by compounding and using three surfactants. However, the stability of the composition at high temperature or low temperature is not ideal, and the composition is found to be optimal in stability at high temperature, low temperature and variable temperature by repeatedly adjusting the formula, wherein the weight ratio of the surfactant is 1 (1-5) of fatty acid methyl ester ethoxylate sodium sulfonate, decyl sulfobetaine and sodium lauroyl amphoacetate. The three components are compounded under the system of the invention to have synergistic effect, so that the compatibility of the plant extract and the simulated melanin precursor can be better regulated, the oil-water interfacial tension can be reduced to an ultralow level, the oil-water interface is stabilized, and meanwhile, the surfactant is found to promote the oxidative polymerization of the simulated melanin precursor to become melanin, and the dyeing time is shortened.
