Description

Non-oxidative hair dye composition, non-oxidative hair dye composition and non-oxidative hair dye containing thereof 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, excellent dyeing power as well as less water dripping after dyeing, so that non-oxidizing hair dye is excellent It relates to a composition, a non-oxidative hair dye containing the same, and a hair dyeing method using the same.

Recently, with the development of modern medicine, as human life is extended and quality of life is improved, the importance of healthy life and the desire for beauty of appearance have increased. As such, the desire to look younger and more beautiful than age has emerged as an interest in hair dyeing that can be expected to have a great effect at a small cost. The most commonly used dyes for hair dyeing include p-phenylenediamine (PPD), m-aminophenol, o-aminophenol and resorcinol. It contains ingredients, especially PPD, which causes skin irritation, eczema, and inflammation of the scalp, causing allergic contact dermatitis. In severe cases, swelling of the face and painful pain, or itching, eye pain, vision damage, scalp disease, and hair loss Back side effects. In addition, in the dyeing process, an ammonia solution with a pH of about 9-10 used for chemical penetration into the cuticle layer can obtain a desired color, but causes hair damage. If hair damage occurs, such as cracking or breaking of the hair, recovery is impossible and it is removed by cutting.

Natural dyes are difficult to pursue a variety of color changes and have the disadvantages of poor fastness and reproducibility, but they are emerging as alternatives to hair dyes due to their natural color and non-toxic effect on the human body and less environmental pollutants than synthetic dyes. Among recent studies on natural dyes, it has been reported that anthocyanin pigments, which are multicolored dyes, are used not only as a variety of mordants, but also because they can implement various colors with a single color by selecting the mordant conditions and mordant methods, and are therefore applicable to hair dyeing.

On the other hand, in general, hair dyes can be classified into permanent hair dyes (oxidative hair dyes), semi-permanent hair dyes (non-oxidized hair dyes) and temporary colorants according to the durability of the colored color and the properties of the composition.

In the case of an oxidative hair dye, a low molecular weight oxidizing dye causes an oxidative polymerization reaction in the hair to form a pigment. It is a most widely used class of hair dyes because it can obtain various colors and has excellent hair dye characteristics. The oxidizing hair dye composition contains one or more dye precursors and one or more couplers to form a dye by being oxidized by an oxidizing agent, and the hair dye composition for oxidative dyeing is an oxidizing agent composed of a dilute hydrogen peroxide solution or the like immediately before application to the hair. Mix and use. The purpose of using these hair dyes is to dye the hair as completely as possible and to maintain the hair dye effect for a long time.

On the other hand, the non-oxidative hair dye is a hair dye useful for providing natural color close to the primary color to the hair, and has relatively little hair damage and can be easily treated simultaneously with perm, so its utilization is gradually expanding. Unlike the non-oxidizing hair dye, the non-oxidizing hair dye does not use an oxidation reaction, but dyes the hair through a buried reaction of a metal salt and a natural dye.

However, currently commercially available non-oxidative hair dyes have a disadvantage of not only having low hair dyeing effect but also easily discoloring due to water dripping caused by repeated shampooing.
