Description

Technical Field

[0001] The invention belongs to the technical field of scalp cleaning and care products, and in particular relates to a cleaning and care composition that can safely dye hair and relieve scalp irritation. Background Art

[0002] The hair dye products on the market mainly use p-phenylenediamine colorant, hydrogen peroxide oxidation agent and ammonia and other chemical cleaning and care combinations to dye the hair. p-Phenylenediamine (p-Phenylenediamine), also known as Urs D, is an organic compound with a chemical formula of C6H8N2. p-Phenylenediamine reacts with oxygen to produce new colors. p-Phenylenediamine has a strong affinity for keratin in hair, which makes it better fix the color during the oxidation process, making the hair dyeing effect more durable.

[0003] However, if p-phenylenediamine enters the water source, it will cause the death or even extinction of many aquatic organisms. On October 27, 2017, the World Health Organization's International Agency for Research on Cancer published a list of carcinogens, and p-phenylenediamine was classified as a Class 3 carcinogen. Although the EU has not yet declared p-phenylenediamine a carcinogen, it has banned 2-chloro-p-phenylenediamine (and its salts), that is, p-phenylenediamine-based cleaning compositions are highly allergenic and have also been banned by the EU.

[0004] Paraphenylenediamine and its derivatives are common cleaning compositions, such as 2-oxy-p-phenylenediamine, 2-chloro-p-phenylenediamine sulfate, 4-nitro-o-phenylenediamine, 4-nitro-o-phenylenediamine sulfate, p-phenylenediamine, p-phenylenediamine HCl, p-phenylenediamine sulfate, etc. It should be noted that some phenylenediamine and its derivatives are not allowed cleaning compositions, such as 2-methyl-m-phenylenediamine, 4-ethoxy-m-phenylenediamine and its salts, 4-methyl-m-phenylenediamine and its salts, m-phenylenediamine and its salts, o-phenylenediamine and its salts, etc. are all banned substances and are not allowed to be used in cosmetics.

[0005] Aminophenol and its derivatives are also common cleaning compositions, such as 2,4-diaminophenol, 2,4-diaminophenol HCl, m-aminophenol, m-aminophenol HCl, m-aminophenol sulfate, p-aminophenol, p-aminophenol sulfate, p-methylaminophenol, etc. These substances can be used in hair dye cosmetics as required. However, aminophenol also has certain side effects. It can interfere with the biochemical processes of cells, interfere with the metabolic pathways of cells, and lead to abnormal cell function; it may cause lipid peroxidation and damage of cell membranes, increase the permeability of cell membranes, and interfere with the exchange of substances inside and outside cells; it may cause DNA damage, including DNA breakage, base damage, or the formation of DNA additives. These damages may cause cell mutations and increase the risk of cancer; they can induce oxidative stress, that is, excessive production of active oxidants in cells, such as free radicals. These free radicals can damage the proteins, lipids and DNA of cells, leading to cell dysfunction.

[0006] Hydrogen peroxide is a common oxidizing agent in hair care compositions, also known as a developer. This raw material, which comes in different forms and strengths, can catalyze color formation and produce longer-lasting colors. The more developer is used, the more sulfur it removes from the hair. Without sulfur, hair becomes hard and light. Therefore, long-term use can cause hair to become dull, split, and even cause severe hair loss. The hair quality is severely deteriorated and the hair will never be restored to a healthy state.

[0007] The "Technical Specifications for Safety of Cosmetics" (2015 edition) contains 75 approved hair care compositions and recommends two HPLC detection methods. Many papers have conducted tests and analyses on imported and domestic hair dye products on the market. The results show that the proportion of products using a single hair care composition raw material has gradually decreased, and compounding is more common. The proportion of 3 to 5 dyes in the formula accounts for more than 60%. According to the determination method of "7.2 p-phenylenediamine and other 32 components" in the "Technical Specifications for Safety of Cosmetics" (2015 edition), the most frequently used cleaning compositions in commercially available products include p-phenylenediamine, p-aminophenol, m-aminophenol, resorcinol, toluene-2,5-diamine sulfate, 4-amino-2-hydroxytoluene, 2-methylresorcinol, 2,4-diaminophenoxyethanol hydrochloride, N,N-bis(2-hydroxyethyl)p-phenylenediamine sulfate, 1-naphthol and other 10 kinds, followed by phenylmethylpyrazolone, 4-amino-m-cresol, 2-amino-3-hydroxypyridine, 4-chlororesorcinol, o-aminophenol, p-methylaminophenol sulfate, 4-nitro-o-phenylenediamine and other 7 kinds. There are as many as 12 kinds of cleaning and care compositions used in imported products, while there are 8 kinds in domestic products. The former is more diverse than the latter. The two also have different preferences for the use of cleaning and care compositions. For example, the most commonly used cleaning and care compositions in imported products are resorcinol, m-aminophenol and toluene-2,5-diamine sulfate, while the most commonly used cleaning and care compositions in domestic products are resorcinol, 4-amino-2-hydroxytoluene and p-phenylenediamine.

[0008] According to the "Cosmetic Safety Technical Specifications" (2015 edition), the maximum allowable concentrations of resorcinol (RCN) are 1.25%, meta-aminophenol (MAP) is 1%, toluene-2,5-diamine sulfate (25DTS) is 4% (calculated as free radicals), 4-amino-2-hydroxytoluene (PAOC) is 1.5%, and p-phenylenediamine (PPD) is 2%. The safety issues of hair dye cosmetics are mainly sensitization and carcinogenicity. Summary of the invention

[0009] The object of the present invention is to provide a hair care composition which can safely dye hair and relieve scalp irritation.

[0010] In order to achieve the above object, the present invention provides the following technical solutions:

[0011] A hair care composition capable of safely dyeing hair and relieving scalp irritation, the hair care composition comprises, by weight, 0.001 to 2 parts of a moisturizer, 0.02 to 0.3 parts of a chelating agent, 5 to 10 parts of a thickener, 2 to 15 parts of an effective component, 3 to 8 parts of a cationic conditioning agent, 0.001 to 1.0 parts of a pH regulator, and 0.01 to 2 parts of a preservative.

[0012] Furthermore, the functional components include 1 to 5 parts of basic dye pigment and 3 to 8 parts of oatmeal acyl anthranilic acid by weight.

[0013] Further, the basic dye pigment can be selected from Basic Brown 16, Basic Brown 17, Basic Yellow 57, Basic Red 76, Blend, Basic Blue 99, HC Blue 16, Blend, Basic Orange 31, Basic Yellow 87, and Basic Red 51. These are stable between pH 4 and 11. The preparation method of the basic dye is as follows: the surface modified toner is subjected to hydrophobic treatment and hydrophilic treatment.

[0014] The present invention uses basic dyes for dyeing, and basic dyes have the following advantages when coloring hair: Mildness: Basic dyes usually do not require the use of strong oxidants (such as hydrogen peroxide), which makes them milder to the hair and scalp and less likely to cause damage or allergic reactions. Easy to use: Since no complex chemical reactions are involved, the application process of basic dyes is relatively simple, and users can do it themselves at home without the help of professional hairdressers. Fast color development: Basic dyes can develop color relatively quickly, and usually only a short waiting time is required to complete the dyeing process. Basic dyes provide a wide range of color options to meet the personalized needs of different users.

[0015] The reason why the alkaline dye has less irritation to the scalp after adding oatmeal yl anthranilic acid in the present invention is that the composition of oatmeal yl anthranilic acid can relieve skin inflammation and itching. Oatmeal yl anthranilic acid may inherit this characteristic and can reduce the irritation of chemicals to the scalp during hair dyeing; oatmeal yl anthranilic acid may form a protective film on the surface of the scalp, reducing the chance of the dye directly contacting the scalp, thereby reducing the potential damage of the chemical to the scalp. It has a moisturizing effect: it can maintain the moisture balance of the scalp and prevent the dryness and discomfort of the scalp caused by the use of chemicals during hair dyeing. Oatmeal yl anthranilic acid is added to the formula, which may reduce irritation by adjusting the pH value of the hair dye to make it closer to the natural pH value of the scalp. Sustained release effect: certain ingredients can control the release rate of the dye so that the dye acts on the hair more slowly, which can reduce the instantaneous impact of the hair dye on the scalp and reduce irritation. By adding oatmeal acyl anthranilic acid, the hair dye formula can become milder, reduce scalp stimulation, and provide a certain care effect, making the hair dyeing process safer and more comfortable.

[0016] Furthermore, oatmeal yl anthranilic acid includes the following components in parts by weight, based on a total of 100 parts: 0.3 to 1 part of 1,2-pentanediol, 0.01 to 0.1 part of 4-tert-butyl cyclohexanol, 0.5 to 2 parts of PEG-40 hydrogenated castor oil, 3 to 6 parts of trideceth-9, 0.001 to 0.005 parts of hydroxyphenylpropionamide benzoic acid, 5 to 10 parts of propylene glycol, and the rest is water.

[0017] The present invention adds oatmeal acyl anthranilic acid, and the various ingredients in this formula can work together to improve the scalp comfort of the care composition and the washing fastness of the color after hair dyeing. 1,2-Pentanediol: It can help other ingredients to dissolve better, while bringing moisturizing effect to the skin, reducing the dry feeling that may be caused by the care composition. 4-tert-butyl cyclohexanol: This ingredient may be used as a fragrance or solvent, and can also help adjust the smell of the formula to make the hair dyeing experience more pleasant. PEG-40 hydrogenated castor oil: It can help oily and aqueous ingredients to mix better, improve the stability and spreadability of the product, and also help the dye to adhere to the hair better. Tridecyl alcohol polyether-9: It is used to improve the wettability and spreadability of the care composition, so that the care composition is easier to be evenly distributed on the hair, thereby improving the dyeing effect. Hydroxyphenyl propionamide benzoic acid: The low concentration of use can also reduce irritation to the skin. Propylene glycol: Propylene glycol can help the active ingredients in the care composition to better penetrate into the cortex of the hair, improve the dyeing effect, and also provide a certain moisturizing effect on the scalp. The formula aims to achieve the following goals: Improve scalp comfort: By adding moisturizing ingredients (such as 1,2-pentanediol and propylene glycol), the dryness and discomfort of the scalp that may occur during the hair dyeing process can be reduced. Improve washing fastness: By increasing the adhesion of dyes (such as PEG-40 hydrogenated castor oil and trideceth-9), the dyeing is made more durable and less likely to fade due to shampooing. The formula design not only takes into account the hair dyeing effect, but also pays attention to user experience and safety.

[0018] Furthermore, the moisturizing agent includes at least one of glycerin, propylene glycol, sodium hyaluronate, panthenol, and butylene glycol.

[0019] Furthermore, the chelating agent includes one or more of EDTA-2Na, EDTA-4Na, caprylhydroxamic acid, and p-hydroxyacetophenone.

[0020] Furthermore, the thickener includes one or more of hydroxyethyl cellulose, xanthan gum, cetearyl alcohol, and PEG-14M.

[0021] Furthermore, the cationic conditioning agent includes one or more of quaternium-80, polyquaternium-10, quaternium-82, polyquaternium-67, dioleoylethyl hydroxyethyl methyl ammonium methyl sulfate, trimethylolpropane tricaprylate / tricaprate, and stearyl trimethyl ammonium chloride.

[0022] The present invention adds a moisturizer and a cationic conditioning agent at the same time, and the synergistic effect of these ingredients in the hair care composition can improve the scalp comfort of the hair care composition and enhance the bleaching and dyeing fastness of the color after hair dyeing. Moisturizer: It can attract and retain moisture, helping to maintain the moisture balance of the scalp. By maintaining the appropriate moisture of the scalp, the dryness and irritation caused by chemicals to the scalp during the hair dyeing process can be reduced, thereby improving the comfort of the user. Cationic conditioning agent: This type of compound is usually positively charged and can interact with the negative charge in the hair, so that the hair becomes soft, smooth, and easy to comb. They can also form a protective film on the scalp, reducing the chance of chemicals directly contacting the scalp and reducing irritation. Moisturizer: In addition to the moisturizing effect, the moisturizer can also help the dye molecules better penetrate into the stratum corneum of the hair, thereby increasing the amount of pigment attached. When the dye penetrates deeper into the hair, the color will be more durable and not easy to be washed off. Cationic conditioning agent: Cationic conditioning agent can enhance the binding force between the dye and the hair fiber. By interacting with the keratin in the hair, they not only make the hair softer and smoother, but also help fix the dye so that it is not easy to fall off. In addition, these conditioners can also fill the damaged parts of the hair, repair the hair scales, and further enhance the adhesion of the dye. The humectant and the cationic conditioner can work together to increase the permeability of the dye to the hair. The humectant helps soften the stratum corneum, and the cationic conditioner strengthens the combination of the dye and the hair through electrostatic action. The two together promote the deeper penetration of the dye into the hair. Reduce chemical irritation: The humectant can reduce the dryness of the scalp, and the protective film formed by the cationic conditioner can reduce the direct irritation of the chemical substances to the scalp. The two together reduce the discomfort during the hair dyeing process. The synergistic effect of the humectant and the cationic conditioner in the washing and care composition of the present invention is that they can not only improve the application experience of the washing and care composition, but also improve the durability of the color after hair dyeing from both physical and chemical levels. Such a formula design takes into account the user's immediate comfort experience and the long-term color retention effect.

[0023] Furthermore, the pH regulator includes one or more of citric acid, sodium hydroxide, arginine, potassium hydroxide, lactic acid, and triethanolamine.

[0024] Furthermore, the preservatives include one or more of benzyl alcohol, dichlorobenzyl alcohol, phenoxyethanol, sodium salicylate, methylchloroisothiazolinone, methylisothiazolinone, sodium benzoate, potassium sorbate, and DMDM ​​hydantoin.

[0025] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows: the present invention utilizes alkaline dyes, which are cationic and water-soluble, and can safely, efficiently and conveniently dye hair, without oxidation or ammonia. Since p-phenylenediamine can be absorbed through the skin, it may cause skin allergies after use, and its pungent smell can easily cause respiratory irritation, and hydrogen peroxide can easily cause hair to dry and turn yellow. In order to avoid the above situation, alkaline dyes can be used to color the hair, because hair scales are more easily opened under alkaline conditions. At the same time, oatmeal acyl anthranilic acid is added, which, as a "sensitive scalp regulator", can reduce the calcium ion flow in the membrane of inflammatory scalp cells, restore it to normal levels, enhance scalp tolerance, and effectively relieve the itching and irritation of the scalp. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 It is a combing force curve diagram of the product of the present invention and the commercially available product. DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the following examples, the cleaning compositions of Examples 1-10 were added to water in weight percentages. The compositions are shown in Tables 1 and 2.

[0029] Table 1 Proportions of Examples 1-5

[0030]

[0031] Table 2 Proportions of Examples 6-10

[0032]

[0033]

[0034] Comparative Example 1

[0035] The difference between this comparative example and Example 1 is that the effective component does not include oatmeal acyl anthranilic acid.

[0036] Comparative Example 2

[0037] The difference between this comparative example and Example 1 is that oatmeal yl anthranilic acid includes the following components in parts by weight, based on a total of 100 parts: 0.2 parts of 1,2-pentanediol, 0.12 parts of 4-tert-butyl cyclohexanol, 0.2 parts of PEG-40 hydrogenated castor oil, 2 parts of tridecyl alcohol polyether-9, 0.009 parts of hydroxyphenyl propionamide benzoic acid, 2 parts of propylene glycol, and the rest is water.

[0038] Performance Testing

[0039] A total of 280 people were followed up in the test, including 140 females and 140 males aged between 20 and 40 years old. The people were randomly divided into 14 groups, with 20 people in each group, and 10 males and 10 females. Each group used the products prepared in Examples 1-12 and Comparative Examples 1-2 to dye their hair once, and repeated the test after eight months, for a total of three times. After each hair dyeing, the itching condition of the head was scored on that day, and the average score of each group was taken to obtain the average score of the itching of the above five application examples.

[0040] Among them, no itching is 5 points, local itching sometimes is 4 points, local itching often is 3 points, itching all over the head is 2 points, and severe itching all over the head is 1 point.

[0041] Test the washing fastness and rinse fastness.

[0042] Washing fastness: Use the commercially available CLEAR silicone-free shampoo to wash and blow-dry the completely dyed black white hair. After 20 cycles, observe the color of the washed hair and divide the color into grades 1-5. The higher the grade, the darker the color and the higher the color fastness after dyeing.

[0043] Rinse fastness: Use common commercially available Yumei bleaching powder and 6-degree hydrogen peroxide, mix the two in a volume ratio of 1:1, and evenly apply them to the hair that has been dyed at the same time. Wash and blow dry after 5 minutes, observe the color of the hair after rinsing, and divide the color into levels 1-5. The higher the level, the darker the color and the higher the color fastness after dyeing.

[0044] The results are shown in Table 1

[0045] Table 1 Performance test results

[0046]

[0047]

[0048] As shown in Table 1, the washing and conditioning compositions of Examples 1-12 can effectively relieve the itching and irritation of the scalp and have high washing resistance. Without adding oatmeal acyl anthranilic acid or changing the formula, the effect is reduced.

[0049] In the hair combing evaluation, we recorded the peak combing force and average combing force of the test sample of Example 1 for product efficacy evaluation. The combing force refers to the friction resistance of the hair to the comb; the peak combing force refers to the maximum combing force of the comb when combing the hair, that is, the peak value of the friction resistance during the combing stroke, which usually occurs at the tail end of the hair; the average combing force is the combing work divided by the distance the comb passes through the hair. In the test, the average combing force of the middle section of the hair is selected for evaluation.

[0050] The principle of hair combing effectiveness evaluation is to record the changes in the peak and average combing force during the process of combing the hair, compare the differences before and after using the test sample, and evaluate the effectiveness. The smaller the peak combing force and the average combing force, the better the smoothness of the hair; the greater the change in the peak combing force and the average combing force, the greater the improvement in hair combing. Figure 1 It can be seen that the hair care and dyeing composition made with the basic dyes prepared in Example 1 has better smoothness than three commercially available hair care compositions.

[0051] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
