Embodiment 1

[0015] Embodiment 1, the extraction of seabuckthorn pigment

[0016] Using ethanol solution with a volume fraction of 95% as a solvent, the volume of the solvent is 4 to 16 times the mass of seabuckthorn freeze-dried powder, heated and extracted at 50 to 70°C for 2 to 4 hours, and the extracted solution is recycled by rotary evaporation to obtain seabuckthorn yellow pigment. Dissolve seabuckthorn yellow pigment in water, add 10ml of absolute ethanol, then dilute to 50ml with deionized water, measure its absorbance A at a wavelength of 400nm, and calculate the concentration of the extracted pigment.

[0017]

[0018]

[0019] According to the absorbance value, the concentration of seabuckthorn pigment was calculated and compared respectively. The results are shown in the table below and attached figure 1 , 2 , 3.

Embodiment 2

[0022] Embodiment 2, the preparation of seabuckthorn pigment hair dye cream

[0023] Seabuckthorn pigment hair dye creams were prepared according to different proportions.

[0024] ① Agent A contains 0.5g of cysteine, 0.5g of CMC (carboxymethyl cellulose), 5ml of sodium hydroxide with a mass volume fraction of 5%, and 10ml of water; agent B contains 0.01g of seabuckthorn yellow pigment, 0.1ml of absolute ethanol, Glycerin 0.1ml, CMC (carboxymethyl cellulose) 0.05g, water 8ml; agent C contains acetic acid 0.1ml, ferrous chloride 0.2g, sodium sulfite 1g, kason 0.001g, water 10ml.

[0025] ② Agent A contains 1g of cysteine, 1g of CMC (carboxymethyl cellulose), 10ml of sodium hydroxide with a mass volume fraction of 5%, and 20ml of water; agent B contains 0.1g of seabuckthorn yellow pigment, 1ml of absolute ethanol, and 0.3ml of glycerin , CMC (carboxymethylcellulose) 0.1g, water 10ml; agent C contains acetic acid 0.5ml, ferrous chloride 0.3g, sodium sulfite 2g, kason 0.005g, wat...

Embodiment 3

[0037] Embodiment 3, p-phenylenediamine quantitative analysis

[0038] Carry out gas chromatographic analysis of agent B, the chromatographic conditions are: the chromatographic column is a DB-5MS capillary column, the specification is (30m×0.25μm×0.25μm), the initial temperature of the chromatographic column is 90°C, keep it for 1min, and increase the temperature at 20°C / min to 280°C, hold for 15min; split ratio is 50:1, carrier gas is high-purity helium, carrier gas flow rate is 1.0mL / min; splitless injection, injection volume is 0.2μL; inlet temperature is 220°C; mass spectrometry Conditions: transfer line temperature is 280°C, EI ion source temperature is 250°C, solvent delay is 3min, the detection mode is total ion scanning mode (TIC), and the scanning range is 40-450m / z.

[0039] The test results show that the dye B agent prepared according to the scheme of the present invention does not contain p-phenylenediamine and is safer for the human body.

Abstract

The invention discloses a natural hair dye prepared by using seabuckthorn yellow pigment. The natural hair dye includes agent A, agent B and agent C. Agent A includes organic acid, thickener, alkali and solvent; agent B includes pigment, solvent, moisturizing agent and thickener; agent C includes pH regulator, metal salt, preservative, and solvent. The pigment used in agent B comes from seabuckthorn, and the seabuckthorn yellow pigment obtained by extracting with ethanol solution is used as the main component of the hair dye.

Description

technical field [0001] The invention discloses a natural plant hair dye, which mainly uses seabuckthorn yellow pigment and belongs to the field of cosmetics. Background technique [0002] Hair dye cosmetics have the effect of changing the color of hair, commonly known as hair dye. Since the reform and opening up, under the influence of international popular hair color, my country has also launched hair dyes of various shades one after another, which makes my country's hair dye market shine. Most of the hair dyes commonly used in the market are oxidative hair dyes, which do not contain the so-called dyes, but contain dye intermediates and couplers. After the dye intermediates and couplers penetrate into the cortex of the hair, oxidation reactions occur , Coupling and condensation reactions form larger dye molecules, which are enclosed in the hair fiber. A number of studies have confirmed that this oxidative hair dye has certain damage to hair, is highly toxic, and easily ca...
