Embodiment 1

[0033] The permanent hair dye prepared by the natural plant-derived dye of the present embodiment and enzyme is composed of two components of agent I and agent II, specifically as follows:

[0034] Preparation of Agent I: Swell 4g of hydroxyethyl cellulose with 66.2g deionized water, add 3g glycerin, 1.5g simethicone, 25g aucubin (purity 60%), 0.1g water-soluble essence, 0.2g Sodium hydroxymethylglycinate, adjust the pH to 8 with 10% potassium hydroxide, stir for 15-20min, and discharge.

[0035] Preparation of agent II: Heat 37.5g of deionized water to 70-80°C, take 16.88g of deionized water and add 1.8g of triethyl citrate, 0.9g of glyceryl monostearate, 1.1g of Tween-80 at high speed Emulsification and shearing. At this time, the solid content of the emulsified liquid is about 15%. If there are too many foams, add simethicone oil to defoam in an appropriate amount, and then add 9.38g of deionized water to the emulsified liquid, stir to room temperature, and emulsify the liq...

Embodiment 2

[0038] The permanent hair dye prepared by the natural plant-derived dye of the present embodiment and enzyme is composed of two components of agent I and agent II, specifically as follows:

[0039] Preparation of Agent I: Swell 4g of hydroxyethyl cellulose with 64.9g deionized water, add 3g glycerin, 1.8g simethicone, 26g aucubin (purity 60%), 0.1g water-soluble essence, 0.2g Sodium hydroxymethylglycinate, adjust the pH to 8.5 with 10% potassium hydroxide, stir for 15-20min, and discharge.

[0040] Preparation of agent II: Heat 37.5g of deionized water to 70-80°C, take 16.88g of deionized water and add 1.8g of triethyl citrate, 0.9g of glyceryl monostearate, 1.1g of Tween-80 at high speed Emulsification and shearing. At this time, the solid content of the emulsified liquid is about 15%. If there are too many foams, add simethicone oil to defoam in an appropriate amount, and then add 9.38g of deionized water to the emulsified liquid, stir to room temperature, and emulsify the l...

Embodiment 3

[0043] The permanent hair dye prepared by the natural plant-derived dye of the present embodiment and enzyme is composed of two components of agent I and agent II, specifically as follows:

[0044] Preparation of agent I: swell 4g of hydroxyethyl cellulose with 65.6g deionized water, add 2.5g glycerin, 1.5g simethicone, 26g aucubin (purity 60%), 0.2g water-soluble essence, 0.2 g sodium hydroxymethylglycinate, adjust the pH to 7 with 10% potassium hydroxide, stir for 15-20min, and discharge.

[0045] Preparation of agent II: Heat 37.5g of deionized water to 70-80°C, take 16.88g of deionized water and add 1.8g of triethyl citrate, 0.9g of glyceryl monostearate, 1.1g of Tween-80 at high speed Emulsification and shearing. At this time, the solid content of the emulsified liquid is about 15%. If there are too many foams, add simethicone oil to defoam in an appropriate amount, and then add 9.38g of deionized water to the emulsified liquid, stir to room temperature, and emulsify the ...

Abstract

The invention relates to a permanent hair dye prepared from natural plant-derived dyes and enzymes, which consists of the following two components: Agent I (ointment, pH 6-10) and Agent II (powder). Agents Ⅰ and Ⅱ provide dyes and enzymes respectively. After mixing, they form brown to black dendritic polymer precipitates, which can dye hair into brown or black. The permanent hair dye has strong adhesion to hair fibers, natural color and no irritation to skin. Among them, agent II adopts spray-drying microcapsule technology, which effectively solves the problem of poor stability and short shelf life of the enzyme, which is easily affected by environmental factors such as light, heat, oxygen, humidity and pH value due to its active nature. The prepared enzyme powder has good functional properties, stable storage and convenient use. The hair dye of the invention is a permanent hair dye, does not contain aniline toxic substances, is harmless to human body, and does not produce toxic substances to human body during the hair dyeing process, is very safe and has good dyeing effect.

Description

technical field [0001] The invention belongs to the technical field of hair dyeing cosmetics, in particular to a permanent hair dye prepared from natural plant-derived dyes and enzymes. Background technique [0002] Hair dye cosmetics refer to chemical daily products that can change the color of hair. Hair dyeing is actually the hair dye starting from the interface reaction such as contact wetting and adsorption of the outermost layer of the hair epidermis, and then reaching the hair epithelium and hair pith through the complex of the cell membrane to make it soak and diffuse, and "polymerization" occurs depending on the situation. "Reaction, acting on the hair to change its colour, see figure 1 . From the hair dyeing mechanism, according to the different parts of the dyeing, the hair dye can be divided into figure 2 Classify as shown. According to the fastness of dyeing, it can be divided into three categories: temporary, semi-permanent and permanent; according to the ...
