5.0 ~ 10.0 wt% of methyl pyrrolidone,

It contains 2.0 to 6.0 wt% of glycolic acid.

Hereinafter, detailed contents of each component constituting the hypoallergenic natural hair dye for companion animals will be described.

1) water

The water is a solvent for dissolving the components constituting the natural hair dye, and when the amount is less than 40.0 wt%, the uniform blending composition between the components is not properly achieved, so that the overall functionality such as color expression and dyeing properties of the hair dye is not achieved. There is a risk of dropping, and if it exceeds 55.0 wt%, the flowability is too high and the dyeing operation may not be performed smoothly, 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 desirable to limit it.

2) Hydroxy ethylcellulose

Hydroxy ethylcellulose (Hydroxy ethylcellulose) is a water-soluble polymer obtained by neutralizing, refining, drying and crushing by reacting ethylene oxide with alkaline cellulose by reacting caustic soda on cellulose.

Viscosity characteristics depend on the degree of polymerization of the cellulose body and are soluble in cold water and hot water, but are 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 ~ 12, and particularly, has excellent long-term storage stability in the range of pH 4 ~ 11.

In general, it is used as a thickening agent, film-forming agent, emulsion stabilizer, etc. When used as a film-forming agent, it forms a thin film on the hair and gently wraps it.

When the amount of hydroxyethylcellulose is less than 0.3 wt%, the role of forming a film on the fur of companion animals such as dogs and gently wrapping it is insignificant, and when it exceeds 1.5 wt%, the effect is Since the change is insignificant and insignificant, the amount of the hydroxy ethylcellulose used is preferably limited to within the range of 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 is used to prevent excessive flow of the preparation during dyeing.

The carbomer is a polymer polymer in which acrylic acid is polymerized as a thickener and phase stabilizer most commonly used in cosmetics. When neutralized with an alkali compound, the carbomer gradually increases in the form of a transparent gel and has the ability to absorb and retain water. It is used in various products such as gels, creams, lotions, and shampoos as a thickener, blending agent, and emulsion stabilizer.

If the amount of carbomer is less than 10.0 wt%, the viscosity is low and may flow excessively, and if it exceeds 15.0 wt%, the viscosity is too high and the dyeing operation may not be performed smoothly, so the amount of 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.

4) Natural dye

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

5) Onion skin extract

Since the onion skin extract has excellent dyeing properties while minimizing hair damage during hair dyeing, it is possible to dye without mordant. In addition, since there is little generation of harmful oxygen substances in the skin tissue and the role of removing harmful oxygen quickly, oxidative stress is alleviated, resulting in less tissue damage. This serves to relieve skin irritation.

The onion skin extract,

Wash the onion skin, dry it in the dark, and pulverize it with a dry grinder to prepare a powder.

Mixing the onion skin powder with purified water at the same weight ratio,

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

Filtering the liquid extract extracted with a glass filter,

The filtered extract was concentrated under reduced pressure at 63° C. for 15 hours using a rotary evaporator,

The extract concentrated under reduced pressure is dried with a freeze dryer to form a powder.

If the amount of the onion skin extract is less than 0.5 wt%, the dyeing property may be deteriorated and the skin irritation relief function may be deteriorated. The amount of the onion skin extract is preferably limited to 0.5 to 2.0 wt% based on the total weight of the hair dye.

The extract concentrated under reduced pressure is dried with a freeze dryer to form a powder.

If the amount of the joiner extract is less than 0.5 wt%, the dyeing effect and the hair protection effect are insignificant, and if it exceeds 2.0 wt%, the degree of increase of the dyeing effect and the hair protection effect is insignificant, so the amount of the joiner extract is used. It is preferable to limit it within the range of 0.5 to 2.0 wt% based on the total weight of the silver hair dye.

7) spices

The fragrance is a fragrance that resembles the smell of soil, flowers, and grass that animals such as dogs like.

More specifically, it is used by selecting one of vetiver fragrance, chestnut flower fragrance, or eucalyptus fragrance.

The Vetiver fragrance has a smell similar to the earthy odor, and is a fragrance extracted from Vetiver, which is originated from India and Bengal. And the eucalyptus fragrance gives off the smell of grass.

If the amount of the perfume is less than 0.1 wt%, the scent emission is insignificant, and if it exceeds 0.5 wt%, the scent may be too strong and a feeling of rejection may occur.The amount of the perfume is 0.1 to 0.5 wt% based on the total weight of the hair dye. It is preferable to limit it within the range of %.

8) 95% ethanol (Ethanol, 95%)

The 95% ethanol is a solvent that dissolves the powdered natural dye together with the water, and if the amount is less than 13.0 wt%, there is a problem that the natural dye does not spread evenly, and it is necessary if it exceeds 20.0 wt%.
