Glycolic acid contains 2.0 to 6.0 wt%.

Hereinafter, let's take a look at the specific contents of each component constituting the hypoallergenic natural hair dye for companion animals.

1) water

The water is a solvent for dissolving the components constituting the natural hair dye, and when the amount used is less than 40.0 wt%, the uniform mixing composition between each component is not properly made, so overall functionality such as color expression and dyeing properties of the hair dye is reduced. There is a risk of falling, and if it exceeds 55.0 wt%, the flowability is too high and the dyeing operation may not be smoothly performed, so the water is in the range of 40.0 to 55.0 wt% based on the total weight of the hair dye. It is preferable to limit

2) Hydroxy ethylcellulose

The hydroxyethylcellulose (Hydroxyethylcellulose) is a water-soluble polymer obtained by neutralizing, refining, drying, and crushing by reacting ethylene oxide with alkali cellulose by reacting caustic soda with cellulose.

The viscosity characteristics depend on the degree of polymerization of the cellulose body, and it is soluble in cold water and hot water, but is insoluble in almost all organic solvents except for some. When added to water, it becomes a viscous liquid, and in general, when the concentration is doubled, the viscosity is almost 5 to 10 times. The higher the molecular weight, the higher the concentration, the higher the structural viscosity. The aqueous solution is stable in the range of pH 2 to 12, and particularly in the range of pH 4 to 11, has excellent long-term storage stability.

In general, it is used as a thickener, film former, emulsion stabilizer, etc., and when used as a film former, forms a thin film on hair, etc. and gently wraps it.

When the amount of hydroxyethylcellulose used is less than 0.3 wt%, the role of forming a film on the fur of companion animals such as dogs to gently wrap it is insignificant, and when it exceeds 1.5 wt%, the effect of Since the change is insignificant and meaningless, the amount of hydroxyethylcellulose used is preferably limited to 0.3 to 1.5 wt% based on the total weight of the hair dye.

3) Carbomer (2% Solution)

The carbomer is added to the hair dye and used to prevent excessive flow of the agent during dyeing.

The carbomer is a high molecular polymer polymerized with acrylic acid as a thickener and phase stabilizer most commonly used in cosmetics, and when neutralized with an alkali compound, it becomes a transparent gel and has the ability to absorb and maintain water. As a thickener, admixture, and emulsion stabilizer, it is used in various products such as gels, creams, lotions, and shampoos.

When the amount of the carbomer used is less than 10.0 wt%, the viscosity is low and it may flow excessively, and when it exceeds 15.0 wt%, the viscosity is too high and the dyeing operation may not be performed smoothly, so the amount of the carbomer is It is preferable to limit it within the range of 10.0 to 15.0 wt% based on the total weight of the hair dye.

It is preferable to limit it within the range of 1.0-3.0 wt%.

5) Onion skin extract

The onion skin extract minimizes hair damage during hair dyeing and has excellent dyeability, so that it can be dyed without mordant. In addition, there is less generation of harmful oxygen substances in the skin tissue, and because it plays a role of quickly removing harmful oxygen, oxidative stress is relieved and tissue damage is less. This serves to alleviate skin irritation.

The onion skin extract is

After washing the onion skins, drying them in a dark place, and pulverizing them with a dry grinder to prepare a powder,

The onion peel powder is mixed with purified water in the same weight ratio,

Liquid extraction is performed by heating at 100 ° C for 100 to 150 minutes,

Filtering the liquid extracted extract with a glass filter,
