Description

Technical Field

[0001] This invention belongs to the field of hair dye technology, specifically relating to a hair dye that prevents hair breakage, is hypoallergenic, and repairs hair, and its preparation method. Background Technology

[0002] Hair dye, as an important category in the cosmetics industry, is widely used for covering gray hair, fashion beauty, and personal image management. Based on their dyeing mechanism and durability, hair dyes are mainly divided into three categories: permanent oxidative hair dyes, semi-permanent direct dye hair dyes, and temporary hair dyes. Among these, permanent oxidative hair dyes dominate due to their superior dyeing effect and long-lasting durability.

[0003] However, traditional permanent oxidative hair dyes have an excessively long dyeing time, easily irritate the scalp during the dyeing process, and result in uneven dyeing, damage to hair quality, and breakage. Therefore, solving the problems of long dyeing time, irritation, and breakage associated with permanent oxidative hair dyes is a key research focus in this industry.

[0004] Chinese Patent No. CN 118892437 B discloses a hair dye composition for preventing hair breakage, reducing allergies, and repairing hair, as well as its preparation method and application. The composition consists of agent A and agent B in a mass ratio of 1:0.8-1.5. Agent A is composed of hydrogen peroxide, glycerin, a thickener, cetearyl alcohol polyether, sodium stannate, hydroxyethylidene diphosphate, and water. The raw materials for Agent B are: p-phenylenediamine, sodium sulfite, triethanolamine, urea, Polygonum multiflorum extract, Acorus calamus extract, Nepeta cataria extract, chelating agent, ascorbate, preservative, keratin, trehalose, 4-amino-2-hydroxytoluene, polyquaternium salt, squalane, arbutin, allantoin, bisabolol, emulsifier, polyglutamic acid, stearyl alcohol, wheat germ oil, and water. This technical solution has a good hair dyeing effect, low allergenicity, and good anti-breakage and hair repair effects. However, the dyeing time of this technical solution is as long as 2 hours.

[0005] Chinese patent CN 116570533 B discloses a fast-dyeing hair dye that is a two-component oxidative hair dye, including a dyeing agent and a color developer. The dyeing agent contains oxidative dyes, alkalis, auxiliaries, and hair conditioning agents. The alkalis include, but are not limited to, ammonium hydroxide and diethanolamine. The auxiliaries are a compound of alginate, potassium iodide, and hydrogen iodide. The hair conditioning agents are a compound of fusiforme extract, oyster extract, and hydrolyzed silk protein. The color developer contains hydrogen peroxide solution. Although this technology has a short dyeing time, its repair effect on hair is limited, its tensile strength changes significantly, and its color fastness is poor. Summary of the Invention

[0006] The purpose of this invention is to provide a hair dye that is anti-breakage, hypoallergenic, and repairing, as well as its preparation method. The hair dye provided by this invention, by using specific compound plant extracts and specific emulsifiers, can solve the problems of long dyeing time, irritation, damage to hair, and poor color fastness of traditional permanent oxidative hair dyes.

[0007] To achieve the above objectives, the present invention provides the following technical solution: The first aspect of this invention provides a hair dye that is anti-breakage, hypoallergenic, and restorative, comprising the following raw materials by weight percentage: 8-20% oil phase, 2-5% moisturizer, 2-4% alkali agent, 2-4% cationic polymer, 0.8-1.6% hair conditioner, 2-3% emulsifier a, 0.1-0.5% emulsifier b, 0.5-2% compound plant extract, 0.5-5% dye, 0.3-0.7% antioxidant, 0.2-0.4% fragrance, 0.1-0.5% thickener, 0.1-0.3% chelating agent, 0.1-0.2% emulsifying agent, 0.1-0.2% pearlescent flakes, 0.05-0.2% protein composition, and deionized water to make up the balance to 100%.

[0008] Furthermore, the oil phase is selected from one or more of cetearyl alcohol, paraffin, and liquid paraffin.

[0009] Furthermore, the moisturizer is selected from one or more of glycerin, trehalose, butylene glycol, ethanol, isopropanol, propylene glycol, ethylene glycol, and polyethylene glycol.

[0010] Furthermore, the alkaline agent is selected from one or more of ethanolamine and ammonium hydroxide.

[0011] Furthermore, the cationic polymer is selected from one or more of polyquaternium salt 10, polyquaternium salt 7, polyquaternium salt-22, stearyltrimethylammonium chloride, behenyltrimethylammonium chloride and polysiloxane quaternium salt-8.

[0012] Furthermore, the hair conditioner is selected from one or more of polydimethylsiloxane and cyclopentadimethylsiloxane.

[0013] Furthermore, the emulsifier a is a mixture of lauroyl wheat amino acid potassium and cetearyl alcohol polyether-25.

[0014] Furthermore, the mass ratio of lauroyl wheat amino acid potassium to cetearyl alcohol polyether-25 is 0.5-1:1.5-2.

[0015] Furthermore, the emulsifier b is a mixture of bis-diethoxydiethylenecyclohexane 1,4-dicarboxylic acid ester and methyl glucetol polyether-10.

[0016] Furthermore, the mass ratio of the bis-diethoxydiethylenecyclohexane 1,4-dicarboxylic acid ester and methyl glucetol polyether-10 is 1-2:1.

[0017] Traditional permanent oxidative hair dyes often suffer from problems such as long dyeing time and poor colorfastness due to their coarse texture and uneven mixing with hydrogen peroxide. This invention addresses these issues by employing the aforementioned technical solution, using lauroyl wheat amino acid potassium and cetearyl alcohol polyether-25 as emulsifier a, and bis-diethoxydiethylene cyclohexane 1,4-dicarboxylic acid ester and methyl gluceth-10 as emulsifier b. The combined action of emulsifiers a and b results in a fine paste that allows for faster hair dyeing and longer colorfastness. This is likely due to the synergistic effect of emulsifiers a and b during the emulsification process, which prevents the formation of bubbles in the hair dye and promotes more effective dye penetration, ultimately forming a strong and long-lasting bond.

[0018] Furthermore, the compound plant extract is a mixture of leontopodium alpinum extract, opium cactus extract, and callus culture filtrate of critium maritimum.

[0019] This invention, by employing the above-mentioned technical solution, combines extracts of Edelweiss, cactus, and sea fennel callus culture filtrate. This not only significantly reduces the irritation of hair dye but also reduces hair damage and improves the durability of the dye. This is likely because, in addition to the soothing effects of the extracts themselves, the organic acids they contain can neutralize the damage of alkali to the hair cuticles, while also helping the dye to better penetrate between the cuticles and cortex, effectively locking in the dye and forming a strong, long-lasting bond, preventing the dye from being lost during shampooing or exposure to light.

[0020] Furthermore, the mass ratio of the extract of Edelweiss, the cactus extract and the filtrate of sea fennel callus culture is 3-6:3-6:1.

[0021] Further, the dye is selected from p-phenylenediamine, p-aminophenol, 4-amino-m-cresol, o-aminophenol, toluene-2,5-diamine sulfate, N,N-bis(2-hydroxyethyl)-p-phenylenediamine sulfate, 2-chloro-p-phenylenediamine sulfate, 1-hydroxyethyl-4,5-diaminopyrazole sulfate, m-phenylenediamine sulfate, m-aminophenol, resorcinol, 4-chlororesorcinol, 2,6-dihydroxytoluene, 4-amino-2-hydroxytoluene, 5-amino-6-chloro-o-cresol, 2-amino-2-amino-2-hydroxytoluene, 2-amino-2-amino-6-chloro-o-cresol, 2-amino- ... One or more of the following: 3-hydroxypyridine, 2,6-diaminopyridine, 2,4-diaminoanisole sulfate, 2,4-diaminophenoxyethanol HCl, 2,4-diaminophenoxyethanol sulfate, 2,5-diaminoanisole sulfate, 1-naphthol, phenylmethylpyrazolone, 2-amino-4-hydroxyethylaminoanisole sulfate, 2-amino-6-chloro-4-nitrophenol, 2,6-dihydroxyethylaminotoluene, 5-nitro-2-hydroxyethylaminobenzyl alcohol, and 5-(2-hydroxyethyl)-aminoo-cresol.

[0022] Furthermore, the antioxidant is selected from one or more of sodium sulfite, sodium isoascorbate, butylated hydroxyanisole, butylated hydroxytoluene, and tert-butylhydroquinone.

[0023] Furthermore, the thickener is selected from one or more of hydroxyethyl cellulose, xanthan gum, acrylate / C10-30 alkanol acrylate crosspolymers, and acrylate copolymers.

[0024] Furthermore, the chelating agent is selected from one or more of disodium ethylenediaminetetraacetate, tetrasodium ethylenediaminetetraacetate, and octanoyl hydroxamic acid.

[0025] Furthermore, the fat-applying agent is one or more of behenoxy PG-trimethylammonium chloride, PPG-12-PEG-65 lanolin oil, castor oil ammonium chloride and lauryl lactate.

[0026] Furthermore, the protein composition is a mixture of hydrolyzed keratin / polymethylsiloxane copolymer and lauryl dimethylammonium hydroxypropyl hydrolyzed soy protein.

[0027] Furthermore, the mass ratio of the hydrolyzed keratin / polymethylsiloxane copolymer to lauryl dimethylammonium hydroxypropyl hydrolyzed soy protein is 1-2:1-2.

[0028] A second aspect of this invention provides a method for preparing a hair dye that is anti-breakage, hypoallergenic, and repairing, comprising the following steps: S1. Add half of the deionized water to the emulsifying pot and heat it. S2. Add the moisturizer, cationic polymer, antioxidant, thickener, chelating agent, dye, and compound plant extract to the emulsifying pot and dissolve them. S3. Heat and dissolve the oil phase, hair conditioner, emulsifier a, emulsifier b, and pearlescent flakes, then add them to the emulsification pot for emulsification. S4. After emulsification, add alkali, protein composition, fat additive, flavoring and remaining deionized water and stir until homogeneous to obtain the final product.

[0029] Compared with the prior art, the present invention has the following advantages: 1. This invention uses a combination of extracts from Edelweiss, cactus, and sea fennel callus culture filtrate, which can not only significantly reduce the irritation of hair dye, but also reduce hair damage and improve the durability of hair dye.

[0030] 2. This invention uses lauroyl wheat amino acid potassium and cetearyl alcohol polyether-25 as emulsifier a, and bis-diethoxydiethylene cyclohexane 1,4-dicarboxylic acid ester and methyl gluceth-10 as emulsifier b. The combined action of emulsifier a and emulsifier b can produce a fine paste, which can complete hair dyeing in a short time and has a long-lasting dyeing effect.

[0031] 3. The hair dye provided by this invention can complete the hair dyeing process within 20 minutes and has low irritation. The change rate of the tensile strength of the dyed hair is less than 2%, and the color difference value is less than 3 after 20 cycles of water washing and light exposure.

[0046] Performance Test 1: The hair dye and developer from Examples 1-2 and Comparative Examples 1-8 were mixed evenly at a mass ratio of 1:1 to prepare hair dye cream. Thirty volunteers were selected, and test areas were marked on the back of their necks with a skin pen. 1g of hair dye cream was applied to each test area. After 30 minutes, the hair dye cream was removed from the test areas of the volunteers, and sensory symptoms were recorded. The symptom levels were divided into four levels: × no stinging sensation, × slight itching, × burning sensation, and × stinging sensation. The results are shown in Table 3 below.

[0047] The color developer formula is as follows: by mass percentage, it includes 6% hydrogen peroxide solution, 3% cetearyl alcohol, 2% PEG-40 hydrogenated castor oil, 4% propylene glycol, 3% EDTA-2Na, 0.15% xanthan gum, 0.05% sodium dihydrogen phosphate, 0.01% tetrasodium pyrophosphate, and deionized water to make up the balance to 100%.

[0048] Table 3 Performance Test Results Statistics Table 3 shows that the compound plant extracts directly affect the irritation of hair dyes. Among them, the hair dyes of Examples 1 and 2, Comparative Examples 3, and Comparative Examples 6-8 have lower irritation and lower sensitization. Comparative Example 1: Edelweiss extract was replaced with an equal mass of clove extract; Comparative Example 2: Edelweiss extract was not present; Comparative Example 4: Cactus extract was replaced with an equal mass of ginger root extract; Comparative Example 5: Sea fennel callus culture filtrate was replaced with an equal mass of purslane extract; The resulting hair dye was more irritating.

[0049] Performance Test 2: The hair dye and developer from Examples 1-2 and Comparative Examples 1-8 were mixed evenly at a mass ratio of 1:1 to prepare a hair dye paste. A human hair strand weighing approximately 5 ± 0.5 g and about 15 cm in length was immersed in water for 10 seconds. Then, 10 g of hair dye paste was evenly applied to the hair strand for dyeing. The dyeing process was left on for 20 minutes, followed by rinsing with water and blow-drying. The tensile strength of the hair strand before and after dyeing was then tested according to T / GDCDC 012-2020, and the change rate of tensile strength was calculated using the formula: Change rate of tensile strength = [(Initial tensile strength before dyeing - Tensile strength after dyeing)] / Initial tensile strength before dyeing × 100%. The results are shown in Table 4 below.

[0050] Performance Test 3: In Examples 1-2 and Comparative Examples 1-8, the hair dye and developer were mixed evenly at a mass ratio of 1:1 to prepare hair dye paste. A human hair strand weighing approximately 5±0.5g and about 15cm in length was soaked in water for 10s, and then 10g of hair dye paste was evenly applied to the hair strand for dyeing treatment. The hair was left to stand for 20min, then rinsed with water and blow-dried.

[0051] The dyed hair sample was first soaked in 1000mL of shampoo (the formula is the same as the shampoo formula in Table 4 of Chinese Patent Publication No. CN 114425027 A, with a mass concentration of 5%), shaken and washed for 5 minutes, rinsed with water, blow-dried, and then washed with 80W / m 2The UV wavelength is 200-400nm, and the light is applied for 1 hour, which constitutes one cycle. After 20 cycles, the L1, a1, and b1 values ​​of the dyed hair samples are measured using a colorimeter, and the L0, a0, and b0 values ​​of the dyed hair samples before the cycle are measured. The hair color difference value is calculated as follows: Color difference value ΔE = [(L1-L0)] 2 +(a1-a0) 2 +(b1-b0) 2 ] 1 / 2 The samples of Example 1 and Example 2 after the first cycle are as follows: Figure 1 As shown; the samples of Example 1 and Example 2 after the 20th cycle are as follows. Figure 2 As shown in the figure; the results are shown in Table 4 below.

[0052] Table 4. Statistics on tensile strength and color difference Table 4 shows that the compound plant extracts not only affect the irritation of hair dyes but also reduce hair damage and improve dye durability; emulsifiers can also improve dye durability. Specifically, the hair dyes in Examples 1 and 2 effectively prevent hair breakage and have a longer dye durability. Comparative Example 1 replaced the extract of Edelweiss with an equal mass of clove extract; Comparative Example 2 did not contain Edelweiss extract; Comparative Example 3 replaced the extract of cactus with an equal mass of sea fennel callus culture filtrate; Comparative Example 4 replaced the extract of cactus with an equal mass of ginger root extract; Comparative Example 5 replaced the sea fennel callus culture filtrate with an equal mass of purslane extract. The resulting hair dye showed a large change in the tensile strength of the hair after dyeing, caused some damage to the hair, had a high color difference value, and had poor color fixation effect after dyeing.

[0053] Comparative Example 6 did not contain emulsifier b; Comparative Example 7 replaced potassium lauroyl wheat amino acid with an equal mass of cocamide MEA; Comparative Example 8 replaced methyl gluceth-10 with an equal mass of bis-diethoxydiethylene cyclohexane 1,4-dicarboxylic acid ester. The resulting hair dyes showed a slight increase in the rate of change of hair tensile strength after dyeing, but the color difference value was high, and the color fixation effect after dyeing was poor.

[0054] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
