Description

Technical Field

[0001] This invention relates to acidic decolorizing agents and their preparation methods. Background Technology

[0002] For humans, the pursuit of health and beauty is both a process of self-satisfaction and a means of presenting oneself to others. As living standards improve, people are investing significant energy, time, and capital in pursuing health and beauty. With rising cultural levels, the pursuit of hairstyles and body aesthetics is receiving just as much attention as facial makeup. However, this heightened focus on beauty leads to excessive hair care practices such as perming, blow-drying, dyeing, and manicures, which can have adverse effects, such as physical and chemical damage to the hair and scalp. Furthermore, shampooing often completely removes the natural nutrients, sebum, and moisturizing components that should be retained in the scalp and hair, resulting in dryness, roughness, and even itching. Therefore, there is an urgent need to address these issues.

[0003] Typically, hair bleaching agents are a mixture of an alkaline agent (pH 10.0-11.0) and an oxidizing agent (such as hydrogen peroxide). The alkaline agent and hydrogen peroxide work by bleaching the melanin. During this process, the hair swells, softens, and the cuticle twists and bends, which can cause damage.

[0019] This invention provides an acidic decolorizing agent comprising 30-34 parts by weight of hydrolyzed wheat starch, 28-32 parts by weight of wheat flour, 12-16 parts by weight of potassium persulfate, 4-8 parts by weight of ammonium persulfate, 3.5-7.5 parts by weight of hydroxyethyl cellulose, 1.5-5.5 parts by weight of silica, 1-2 parts by weight of hydroxypropyltrimethylammonium chloride hydrolyzed collagen, 0.8-1.3 parts by weight of guar gum, and 0.8-1... 3 parts by weight of sodium metasilicate, 0.8-1.3 parts by weight of magnesium stearate, 0.8-1.3 parts by weight of magnesium carbonate, 0.8-1.3 parts by weight of disodium EDTA, 0.08-0.12 parts by weight of hydrolyzed keratin, 0.4-0.8 parts by weight of sodium lauryl ether sulfate, 0.3-0.5 parts by weight of titanium dioxide, 0.3-0.5 parts by weight of glucose, and 0.1-0.3 parts by weight of mineral oil.

[0020] The acidic decolorizing agent of the present invention will be described in detail below.

[0021] Typically, hair bleaching agents are used in combination with an alkaline agent (agent 1) with a pH of approximately 10.0-11.0 and an oxidizing agent (agent 2) containing a peroxide (such as hydrogen peroxide). The alkaline agent and hydrogen peroxide work by bleaching the melanin, during which the hair swells, softens, and the cuticle twists and bends, thus causing damage. Therefore, the present invention provides an acidic bleaching agent, preferably with a pH of 4.5-6.5, more preferably 5-6.

[0022] More preferably, the acidic decolorizing agent comprises 31.9 parts by weight of hydrolyzed wheat starch, 30.0 parts by weight of wheat flour, 14.06 parts by weight of potassium persulfate, 6.08 parts by weight of ammonium persulfate, 5.70 parts by weight of hydroxyethyl cellulose, 3.42 parts by weight of silicon dioxide, 1.52 parts by weight of hydroxypropyltrimethylammonium chloride hydrolyzed collagen, 1.14 parts by weight of guar gum, 1.14 parts by weight of sodium metasilicate, 1.14 parts by weight of magnesium stearate, 1.14 parts by weight of magnesium carbonate, 1.14 parts by weight of disodium EDTA, 0.10 parts by weight of hydrolyzed keratin, 0.57 parts by weight of sodium lauryl ether sulfate, 0.38 parts by weight of titanium dioxide, 0.38 parts by weight of glucose, and 0.19 parts by weight of mineral oil.

[0023] Hydrolyzed wheat starch is a hydrolyzed product of wheat starch, prepared by combining wheat starch with fatty acids from olive oil. Therefore, it is an amphoteric surfactant with excellent dispersing ability and skin stability. It revitalizes and promotes the health of skin and hair, while also acting as an active agent that effectively mixes various substances by adsorbing them onto the surface. As a natural ingredient, it also protects hair.

[0024] Wheat flour can be used directly in our diet. It is rich in protein, amino acids, minerals, vitamins, etc. Pharmacological effects include stimulating appetite, providing energy and calories, and also helping to eliminate toxins from the body.

[0025] Potassium persulfate and ammonium persulfate are used as hair bleaching agents.

[0026] Hydroxyethyl cellulose is used as a thickener.

[0027] Silica can reduce inflammation by strengthening hair follicles and improving blood circulation in the scalp.

[0028] Hydrolyzed collagen with hydroxypropyltrimethylammonium chloride can help restore and strengthen hair damaged during the bleaching process.

[0029] Guar gum, an ingredient extracted from guar beans, helps hair retain moisture.

[0030] Sodium silicate accelerates the decomposition of melanin in hair by promoting the breakdown of hydrogen peroxide, thus making the hair's base color brighter. The brighter the base color of the hair, the brighter and more vivid the color will appear after dyeing.

[0031] Magnesium stearate acts as a lubricant and is used in tablet granulation. In this invention, it is used as an acidic decolorizing agent.

[0032] Magnesium carbonate is used as a desiccant, a colorant, and a pH adjuster.

[0033] By using sodium metasilicate, magnesium stearate, and magnesium carbonate in a weight ratio of 0.8-1.3:0.8-1.3:0.8-1.3 to act as an acidic bleaching agent, bleaching can be performed without damaging the hair.

[0034] Disodium EDTA is used as a preservative.

[0035] Hydrolyzed keratin is a hydrolyzed component of keratin obtained through acid, enzyme, or other hydrolysis methods (i.e., an aqueous solution of keratin protein hydrolysate). It is used for hair and skin conditioning. It provides conditioning to hair, revitalizes hair strands, makes styling smoother, and forms a protective film on the hair surface to prevent static electricity. It also maintains elasticity even after bleaching.

[0036] Sodium lauryl ether sulfate is used as a surfactant.

[0037] Glucose is used as a skin moisturizer to maintain skin cells.

[0038] Preferably, the acidic decolorizing agent contains 2-4 parts by weight of a complex functional extract, more preferably, it contains 2.5-3.5 parts by weight.

[0039] The compound functional extract is prepared by the following steps: washing Agrimonia pilosa and Ferula asperata, and drying them at 48-52°C for 2-4 hours; pulverizing the dried Agrimonia pilosa and Ferula asperata, and mixing them in a 1:1 weight ratio to prepare a compound powder; mixing 48-52 parts by weight of the compound powder with 48-52 parts by weight of fermented cocoa extract, and maturing at 8-12°C for 2-4 days; after maturation, filtering to obtain a solid component, mixing 48-52 parts by weight of the solid component with 48-52 parts by weight of purified water, adding 0.8-1.2 parts by weight of Bacillus amyloliquefaciens strain, and fermenting at 28-32°C for 2-4 days; after fermentation, adding 48-52 parts by weight of purified water and extracting at 98-102°C for 9-11 hours to prepare an extract; and concentrating the extract under reduced pressure and freeze-drying it.

[0040] Dragon's tooth grass (Agrimonia pilosa) is a perennial herbaceous plant belonging to the Rosaceae family. According to current research, approximately ten species are distributed in temperate regions of the Northern Hemisphere, as well as Brazil and South America. In Korea, this plant is commonly found in wild mountains, roadsides, and fields, and is also known by various folk names such as Crane Grass, Dragon Sprout Grass, Yellow Sprout Grass, Yellow Dragon Grass, and Earth Fairy Grass. The plant grows to a height of about 15–60 cm, covered entirely in white downy hairs, with alternate, willow-shaped or oblong leaflets. From June to August, clusters of small yellow flowers bloom at the top of the flower stalk. It is widely used in traditional folk remedies and green juice, and is extensively used medicinally to treat lung cancer, liver cancer, esophageal cancer, tumors, as well as for pain relief, hemostasis, antidiarrheal purposes, hematemesis, blood stasis, uterine bleeding, and fever. Recently, many substances in Agrimonia pilosa extract have been widely used as pharmaceutical raw materials, health foods, wild vegetables, and plant nutrients. These include vitamin K, tannic acid, essential oil, luteolin-7-β-glucoside, apigenin-7-β-glucoside, phenolic glucoside, agrimononiin, and agrimonolide. Agrimoniin, in particular, is widely known for its anti-cancer effects.

[0041] Ferula oyster mushroom (Pleurotus eryngii var. ferulae (Pf.)) is a variety of king oyster mushroom. Its English name is Ferula Oyster Mushroom, which literally translates to "Ferula oyster mushroom." In China, it is called Bai Ling Ce Er. It grows wild on Ferula trees in the arid Xinjiang region of China, with a moderate growth temperature of 8–20°C. In Korea, it is suitable for cultivation in spring and autumn. Known for its medicinal properties in China and Central Asia, Ferula oyster mushroom is believed to have effects such as clearing the meridians, relieving coughs and inflammation, and being effective in treating gastrointestinal diseases. According to Korean medical texts, it is a highly functional mushroom effective in detoxifying the body, suppressing coughs, relieving inflammation, and treating gynecological diseases.

[0042] In this invention, after fermentation of Agrimonia pilosa and Ferula asperata, the extracted compound functional extract is used as a decolorizing agent. The compound functional extract utilizes Agrimonia pilosa and Ferula asperata, which are fermented with cocoa extract to increase the effective components. Therefore, the content of effective components such as amino acids is excellent, and the functionality is also outstanding.

[0043] The fermented cocoa extract can be prepared by the following steps: mixing 48-52 parts by weight of cocoa with 48-52 parts by weight of purified water and soaking at 1-5°C for 22-26 hours; after soaking, filtering to obtain solid components, mixing 88-92 parts by weight of the solid components with 8-12 parts by weight of compound mycelium, and fermenting at 28-32°C for 6-8 days; mixing 28-32 parts by weight of the fermented product with 68-72 parts by weight of purified water, heating to 88-92°C, and boiling for 46-50 hours; and after boiling, filtering to obtain the filtrate.

[0044] The composite mycelium is prepared by mixing shiitake mushrooms, birch inoculum, ganoderma lucidum, mulberry fungus, hydrangea, cordyceps, ginseng, oats, barley, and buckwheat in a weight ratio of 1:1:1:1:1:1:1:1:1:1, drying at 48-52℃ for 5-7 hours, and then pulverizing the mixture.

The mixtures were applied to the wig mannequin heads and left for 30 minutes. After washing with warm water, the wigs were dried with a hair dryer.

[0068] The color difference (ΔE) between bleached and untreated hair was measured using a wind photometer under xenon lamp light source conditions of 400-700nm wavelength and 8° reflection angle to analyze the bleaching power. The touch of the hair was expressed on a 5-point scale (5: very good; 4: good; 3: average; 2: poor; 1: very poor). The results are shown in Table 2 below.
