Description

Technical Field

[0001] The invention relates to the field of toiletries, and in particular to a composition for hair care, a hair mask and a preparation method thereof. Background Art

[0002] With the development of modern social economy, people are becoming more and more aware of their individuality and are increasingly pursuing fashion and trends. Frequent perming, dyeing and styling have become a common way for many people to improve their appearance. Although these behaviors can improve the appearance in the short term, in the long run, they will inevitably have a negative impact on the hair and gradually affect the health and physiological state of the scalp.

[0003] The chemicals used in perming and dyeing hair (ammonia, hydrogen peroxide, alkaline hair dyes) can cause the hair scales to open or even peel off, causing the hair to lose its original smoothness and luster. The high-temperature perming and chemical hair dyeing process can also break and recombine the disulfide bonds of the hair keratin, weaken the structural strength of the hair, and make the hair prone to breakage and splitting, and lose its elasticity.

[0004] As a product specially designed for hair care, hair mask can provide deep nourishment and repair, making hair glow with healthy luster and vitality; therefore, more and more people are beginning to pay attention to and use hair masks for daily hair care.

[0005] Currently, the mainstream hair masks on the market mostly use small molecule strong cationic quaternary ammonium salt surfactants containing ammonium chloride groups, such as cetrimonium chloride, stearyl trimethyl ammonium chloride and behenyl trimethyl ammonium chloride, as the core ingredients of the emulsification system.

[0006] Among them, cetrimonium chloride has a small molecular weight, the strongest permeability, and a high cationic density, which greatly enhances its electrostatic attraction to the skin and hair. Although it can provide strong conditioning and excellent smoothness, it is more irritating to the scalp and eyes, and has strong surface activity and degreasing effects, which can easily destroy the natural barrier and microecological balance of the scalp. Long-term use may cause dry and sensitive scalp, and even cause dandruff and hair loss problems. When the scalp is exposed to excessive concentrations of cetrimonium chloride for a long time, it may even induce contact dermatitis;

[0007] Like cetrimonium chloride, stearyl trimethyl ammonium chloride is a quaternary ammonium salt cationic surfactant with strong cationic properties. It is often used as a hair conditioner to reduce hair static electricity and provide a smooth feel. Its fatty acid group is 18 carbons, slightly longer than the 16 carbon cetrimonium chloride, and can be effectively adsorbed on the surface of the hair to form a smooth film. Similar to other quaternary ammonium compounds, stearyl trimethyl ammonium chloride is also irritating to the skin and eyes at higher concentrations, and may cause redness, itching, and even inflammation. Frequent use of products containing stearyl trimethyl ammonium chloride may lead to a cumulative effect on the hair and scalp, making the hair heavy and hardened, and even causing problems such as clogged hair follicles and scalp inflammation;

[0008] Behenyltrimethylammonium chloride is also a quaternary ammonium salt cationic surfactant. It has a 22-carbon long-chain alkyl structure and can form a uniform protective film on the hair surface, providing excellent softening and moisturizing effects. It is very suitable for dry and damaged hair. Its irritation is slightly lower than that of cetrimonium chloride and stearyltrimethylammonium chloride, but it is still a strong cationic surfactant and is still quite irritating. Although it has excellent antistatic and softening effects, it can still cause irritation to sensitive skin at high concentrations.

[0009] The mainstream hair masks and conditioners that are popular on the market now have several other problems besides being highly irritating in the emulsified system and not suitable for direct contact with the scalp:

[0010] On the one hand, without a reasonable compatibility system, it is impossible to provide efficient smoothness and conditioning, nor can it provide the silky texture of silicone oil. Therefore, many hair masks are often effective in a short period of time, but in the long run, the hair quality is not really improved, and the scalp environment is not healthy enough;

[0011] On the other hand, most hair masks on the market have strong fragrances, are potentially irritating and allergenic, and cannot provide real emotional healing value; furthermore, most hair masks on the market, because they add a high proportion of cationic polyquaternium salts and quaternized cationic guar gum, although they have strong conditioning effects and good immediate effects, they have a particularly obvious false slippery feeling when rinsed, and are difficult to rinse thoroughly, requiring a lot of water and time to rinse, which is not in line with the current and future environmental protection concepts of energy saving and water saving.

[0012] Based on the above points, future hair mask products should focus on combining efficient natural ingredients with gentle care while providing a sustainable user experience. Therefore, the market urgently needs to develop a hair mask that is truly scalp and hair friendly, gentle, healthy and efficient, easy to rinse, saves time, has a natural scent, and is a high-quality hair mask with emotional healing value.

[0013] CN109464294A discloses a hydrolyzed keratin hair conditioner, which is characterized in that it is made of the following raw materials in percentage: 2-5% hydrolyzed keratin, 1-3% hydrolyzed vegetable protein PG-propylsilanetriol, 1-3% hydrolyzed collagen, 0.5-2% collagen amino acids, 5-10% glycerol, 1-3% cetrimonium methylsulfate, 1-3% cetearyl alcohol, 1-3% panthenol, 1-2% behentrimonium methylsulfate, 0.1-0.3% quaternary ammonium salt-33, 0.1-0.3% guar hydroxypropyltrimonium chloride, 0.1-0.3% allantoin, 0.2-0.4% DMDM ​​hydantoin, 0.1-0.3% disodium EDTA, 0.05-0.2% essence, and the balance is deionized water. The behentrimonium methylsulfate and cetrimonium methylsulfate added to this solution can enhance conditioning and are milder than behentrimonium chloride and cetrimonium chloride, making the hair smooth and easy to manage. However, the formula also contains a variety of cationic ingredients such as quaternary ammonium salt-33 and guar hydroxypropyltrimonium chloride. Long-term use will lead to an accumulation effect on the scalp, making the hair heavy, hardened, lacking in fluffy feeling, and increasing the difficulty of washing. In addition, the conditioner provided by this solution focuses on immediate smoothness and conditioning, lacking real deep and lasting nourishment and long-term repair effects. At the same time, the formaldehyde-releasing properties of the preservative DMDM ​​hydantoin added to the formula may pose potential risks to health. In addition, the use of artificial fragrances added to the formula will also bring potential irritation and allergy problems.

[0014] CN107693420A discloses a nourishing, repairing and brightening camellia fruit hair conditioner, which is made of the following ingredients, measured by mass: 30-50 parts of camellia fruit emulsion, 1-3 parts of behenyltrimethylammonium chloride, 0.5-1.5 parts of behenamidopropyl dimethylamine, 1-2.5 parts of octadecyltrimethylammonium chloride, 3-5 parts of cetearyl alcohol, 1-2 parts of glyceryl stearate, 1-2 parts of PEG-100 stearate, 1-3 parts of jojoba oil, 0.1-0.5 parts of PPG-3 caprylyl ether, 5-8 parts of glycerol, 0.2-0.5 parts of hydroxyethyl cellulose, 10-30 parts of pure water, 0.1-0.3 parts of tocopherol acetate, 0.02-0.05 parts of citric acid, 0.1-0.5 parts of flavor, and 0.05-0.1 parts of kasone. Although this solution uses a high proportion of camellia oleifera lotion and a small amount of jojoba oil, the choice of vegetable oil is too limited. The core component of camellia oleifera lotion is more than 80% of the monounsaturated fatty acid oleic acid, and the core component of jojoba oil is wax esters composed of long-chain fatty acids and long-chain alcohols. However, the compatibility system of these two vegetable oils cannot fundamentally solve the problems of dry and scaly hair.

[0015] In addition, strong cationic conditioning agents such as behentrimonium chloride and octadecyltrimonium chloride are used in the formula. Although these ingredients have excellent conditioning, antistatic and smoothing effects, they can cause irritation to the scalp and hair, especially for sensitive scalps. In addition, long-term use may lead to a cumulative effect, making the hair heavy and losing its natural fluffy feel.

[0016] Furthermore, the use of fragrances in formulas can bring potential skin irritation and sensitization risks, especially for users with sensitive skin. In addition, although the smell of fragrances can mask the chemical smell in the product, long-term use may cause olfactory fatigue or discomfort.

[0017] CN110075011A discloses a vegetable oil conditioning lotion, which is characterized in that it comprises the following raw materials in percentage by weight: 67.07-83.82% of water, 6-8% of cetearyl alcohol, 3-6% of emulsifier I, 2-5% of amino dimethyl siloxane, 1-6% of polydimethyl siloxane, 0.5-1.5% of cyclopentasiloxane, 1-5% of emulsifier II, 0.6-1 .2%, macadamia seed oil 0.8-1.5%, jojoba seed oil 0.5-2%, stearamidopropyl dimethylamine 0.1-0.3%, guar hydroxypropyltrimonium chloride 0.2-0.8%, sodium lactate 0.2-0.4%, methylparaben 0.1-0.2%, propylparaben 0.05-0.1%, sodium hyaluronate 0.01-0.05%, fragrance 0.1-0.8%, fungicide 0.02-0.08%. Although macadamia seed oil and jojoba seed oil are added to the formula, which have good nourishing and repairing effects, the compatibility system in this scheme is not enough to provide deep nourishing effects, especially in repairing damaged hair, the effect is limited;

[0018] Cationic surfactants such as behentrimonium chloride and guar hydroxypropyltrimonium chloride are used as conditioning agents to provide smoothness and antistatic effects. However, these ingredients can irritate sensitive scalps at high concentrations, especially for people with weak skin barrier function. In addition, these ingredients can cause an accumulation effect on the scalp, and long-term use can cause scalp sensitivity or inflammation. The formula includes a variety of silicone oil ingredients such as aminodimethicone, polydimethylsiloxane, and cyclopentasiloxane, and the addition ratio is extremely high. Although silicone oil can provide excellent smoothness and gloss, making hair look healthier in a short time. However, high concentrations of silicone oil will cause an airtight film to form on the surface of the hair, and long-term use will cause clogging of hair follicles and affect scalp health. In addition, the accumulation effect of silicone oil will also make the hair heavy and difficult to wash. In addition, although the fragrance in the formula can enhance the use experience, it will cause potential irritation to the skin and scalp, especially for users who are sensitive to fragrance.

[0019] CN115025032A discloses a mild scalp-contacting hair conditioner, characterized in that it comprises the following raw materials by mass percentage: component A: 0.1-3% hydroxyethyl cellulose and 0.5-4% glycerol; component B: 1.0-7.0% cetearyl alcohol, 0.5-5% bis-aminopropyl polydimethylsiloxane, 0.5-5% behenamidopropyl dimethylamine, 0.5-4% polydimethylsiloxane; component C: 0.1-3% rosemary extract, 0.05-1% hydroxypropyltrimethylammonium chloride hydrolyzed collagen, 0.01-0.5% hydrolyzed wheat protein, Keratin 0.01-0.5%, lauryl dimethyl ammonium hydroxypropyl hydrolyzed wheat protein 0.01-0.5%, hydrolyzed silk 0.01-0.5%, silk extract 0.01-0.5%, aloe vera leaf extract 0.1-20%, olive oil 0.01-3%, avocado butter 0.01-3%, hydrolyzed rice protein 0.01-2%, lime oil 0.01-3%, disodium EDTA 0.01-0.15%, preservative 0.1-0.2% and acid-base regulator 0.01-0.2% and; component D: preservative 0.1-2%, the balance is water. Although this solution performs well in terms of ingredient diversity and mildness, it only selects olive oil and shea butter as vegetable oils. Both of these vegetable oils feel thick on the skin. The proportion of oleic acid in olive oil can reach nearly 80%. Oleic acid feels thicker and greasy on the skin, and the oil film is relatively strong, which is not light and smooth enough. In addition to oleic acid, avocado butter also contains up to 41.2-56.8% stearic acid. Stearic acid has a thicker texture than oleic acid and a heavy waxy texture. After use, hair tends to become heavy and greasy, and lacks a light feeling.

[0020] In summary, existing hair masks are overly dependent on strong cationic surfactants, polyquaternium salts, cationic guar gum and highly concentrated silicone oils, and are too focused on quick and significant immediate results, lacking long-termism. As time goes by, although users feel obvious improvements in the initial stage of use, long-term accumulation will lead to a series of new scalp and hair problems, such as damage to the scalp barrier, itching, dryness, irritation, heavy and hardened hair, and lack of lightness and breathability.

[0021] Future high-end hair masks need to pay more attention to the mildness and safety of long-term use, and need to focus more on long-term protection of health to meet consumers' demand for safe, effective and lasting hair care. Summary of the invention

[0022] The purpose of the present invention is to solve the problems of the prior art hair masks, such as poor conditioning and repairing effect, short duration, strong irritation, false slipperiness, difficulty in rinsing, strong artificial fragrance, and lack of emotional healing value.

[0028] The second aspect of the present invention provides a method for preparing a hair mask, the method comprising: applying the composition of the first aspect, comprising:

[0029] (1) mixing the components in phase A to obtain material I; and

[0030] Mixing the components in phase B II to obtain material II; and

[0031] Mixing the components in phase C to obtain material III; and

[0032] Mixing the components in phase D IV to obtain material IV; and

[0043] The third aspect of the present invention provides a hair mask prepared by the method described in the second aspect.

[0044] The composition for hair care provided by the present invention adopts a specific type of combination A and combination B as the main components; the hair mask prepared by using such a composition has an excellent regulating and repairing effect, can significantly improve the problems of scalp and / or hair damage, itching, dryness, etc., is mild and non-irritating, easy to rinse, not slippery, has a natural smell, and has an emotional healing effect.

[0045] The present invention is completed based on the following mechanism and through creative research.

[0046] The present invention adopts a mild cationic conditioner, and does not adopt the small-molecule high-cation density surfactants with strong irritation such as cetrimonium chloride, stearyl trimethyl ammonium chloride and behenyl trimethyl ammonium chloride, which are the mainstream in the market, nor does it use any polyquaternary ammonium salt and cationic guar gum, but uses behenamidopropyl dimethylamine, and synergistically matches the components 1 and 2 in the present invention;

[0047] Behenyltrimethylammonium methylsulfate is widely regarded as a milder type of cationic quaternary ammonium salt. Its methylsulfate group is more stable than the ammonium chloride group, reducing the potential irritation to the skin. Therefore, it is often used in hair care products that come into direct contact with the scalp, especially in formulas for sensitive scalps, and its long-chain C 22 Its structure makes it ideal for hair care, providing deep moisturizing and smoothing effects.

[0048] Behenamidopropyl dimethylamine is a relatively mild cationic conditioning agent. It is milder than traditional quaternary ammonium salts and has excellent conditioning effects on hair, helping to repair damaged hair and enhance hair softness and elasticity.

[0049] In addition, the present invention has discovered through creative research that a hair mask prepared by synergistically combining specific amounts of rosehip oil, black sesame seed oil, camellia oil, peony seed oil, perilla seed oil, jojoba oil, hydrogenated rapeseed alcohol, and aminodimethicone has an excellent regulating and repairing effect, can significantly improve problems such as damage, itching, and dryness of the scalp and / or hair, is mild and non-irritating, and is easy to rinse and not slippery.

[0050] Among them, rosehip oil is rich in vitamin A precursors and a variety of unsaturated fatty acids, which can deeply repair damaged hair, promote cell regeneration, and improve the elasticity and glossiness of hair. It also has a certain transdermal anti-aging effect;

[0051] Black sesame seed oil is rich in vitamin E, linoleic acid, sesamin, and sesame linolenic acid, and has powerful antioxidant, anti-aging and nourishing effects. It can enhance the strength and elasticity of hair, reduce breakage and split ends, and provide necessary nutrients to the scalp to promote healthy hair growth; camellia oil is rich in monounsaturated fatty acids (mainly oleic acid) and has good moisturizing and antioxidant effects. It can penetrate deep into the hair, repair the damaged cuticle, and enhance the softness and glossiness of the hair. Camellia oil has excellent anti-inflammatory effects and has a good effect on relieving scalp inflammation. Peony seed oil is rich in unsaturated fatty acids and polyphenols, and has strong antioxidant and anti-inflammatory effects. This oil can help repair damaged hair, enhance the elasticity of hair, and protect the scalp from environmental stress. Perilla seed oil is rich in α-linolenic acid (ALA, a ω-3 fatty acid), which has strong anti-inflammatory and antioxidant effects. It helps improve the health of the scalp, especially for sensitive scalps, and enhances the elasticity and flexibility of hair. Among them, jojoba oil is rich in highly stable wax esters, and its composition is very similar to the natural oils of human skin, with excellent moisturizing and conditioning effects. Its light and stable texture can enhance the gloss and softness of hair and provide long-lasting moisture and protection.

[0052] The hair mask prepared by the composition for hair care provided by the present invention does not use macromolecular cationic conditioning agents such as polyquaternium salts and cationic guar gum, and specifically selects a milder and easier to rinse combination A, and synergistically matches a specific amount of combination B, which can be compounded to condition the hair quality, make the hair texture easy to rinse, and make the hair light and fluffy, and not easy to be thick and greasy.
