Description

Non-oxidative hair dye composition, non-oxidative hair dye comprising the same, and hair dye method using same {nonoxidative hair dye composition, nonoxidative hair dye containing according to and hair dye method using the same}

The present invention relates to a non-oxidizing hair dye composition, a non-oxidizing hair dye containing the same, and a hair dyeing method using the same. More specifically, the dyeing power is excellent, as well as excellent color persistence due to less water drainage after dyeing. A composition, a non-oxidizing hair dye comprising the same, and a hair dyeing method using the same.

In recent years, the development of modern medicine has led to the prolongation of human life and the improvement of the quality of life, and therefore, the importance of healthy life and the desire for beauty of appearance have increased. This desire to look younger and more beautiful than age is manifested in the interest in hair dyeing, which can be expected to have a great effect at a low cost. The most commonly used dyes for hair dyeing include p-phenylenediamine (PPD), m-aminophenol (m-aminophenol), o-aminophenol (o-aminophenol) and resorcinol. In particular, PPD can cause skin rash, eczema and scalp inflammation, causing allergic contact dermatitis, severe swelling of the face and painful bruises, itching, eye pain, vision damage, scalp disease and hair loss. To cause side effects. In addition, the ammonia solution of pH 9-10, which is used for the penetration of chemicals into the cuticle layer in the dyeing process, can cause hair damage although it can achieve the desired color. Hair damage, such as hair splitting or breaking, is impossible to recover and is removed by cutting.

Natural dyes have difficulty in pursuing various color changes and have low fastness and reproducibility. However, natural dyes have emerged as an alternative to hair dyes due to their natural color, non-toxicity to the human body, and less environmental pollutants. In recent studies of natural dyes, anthocyanin pigments, which are multicolored dyes, are not only used as various mordants, but can be applied to hair dyeing by selecting a morbidity condition and a morbidity method to realize various colors with a single pigment.

In general, hair dyes can be classified into permanent hair dyes (oxidative hair dyes), semi-permanent hair dyes (non-oxidizing hair dyes) and temporary colorants according to the durability of the colored color and the characteristics of the composition.

In the case of oxidizing hair dyes, low molecular weight oxidizing dyes cause oxidative polymerization reactions in the hair to form pigments, which are various types of hair dyes because they can obtain various colors and have excellent hair dyeing characteristics. Such an oxidative hair dye composition contains at least one dye precursor and at least one coupler which form a dye by being oxidized by an oxidizing agent, and the oxidizing dye hair dye composition comprises an oxidizing agent consisting of a diluted hydrogen peroxide solution or the like immediately before being applied to the hair. Use by mixing. The purpose of the hair dye is to dye the hair as completely as possible and to maintain the hair dye effect for a long time.

On the other hand, non-oxidative hair dyes are useful hair dyes to provide natural colors close to the primary color to the hair, and the hair damage is relatively small, and can be easily performed at the same time as the perm, the utilization thereof is gradually expanding. Unlike non-oxidative hair dyes, such non-oxidative hair dyes do not use an oxidation reaction, but dye the hair through a mortar reaction of a metal salt and a natural dye.

However, commercially available non-oxidizing hair dyes have a low dyeing effect, and have a disadvantage in that discoloration occurs easily due to water bleeding caused by repeated shampooing.
