Description

Hair care composition and preparation method and application thereof Technical Field The invention relates to the technical field of daily chemicals, in particular to a hair care composition and a preparation method and application thereof. Background In the personal care product industry, especially in the area of hair care, consumers are increasingly demanding products that are not only cleansing and suppleness, but also higher comfort, long lasting moisturization and substantivity to the sensitive scalp. Among them, dimethylamine-based conditioning agents have been favored in recent years because of their mild, environmental-friendly and human-friendly properties, and have become one of the key ingredients for research and development personnel to search for new scalp-friendly formulations. However, this type of conditioning agent also has significant limitations such as low viscosity, difficulty in uniform dispersion and effective adhesion to the hair, which directly affects the moisturizing, nourishing and antistatic effects of the product, thus limiting its wide application. Conventional solutions often rely on other adjuvants to enhance the viscosity and residence capacity of dimethylamine-based conditioning agents. Although this approach can solve the above problems to some extent, it can cause an increase in the complexity of the formulation, while too complex formulations can affect the stability of the product, increase the production costs and development cycle, and also can reduce the overall mildness of the product, increase the risk of discomfort or irritation to the skin and scalp, and thus affect the consumer's use experience. Disclosure of Invention In one aspect, the present invention provides a hair care composition comprising, in mass fraction: 1-5% of dimethylamine conditioner; 4.5-10% of fatty alcohol; 0.2-1.0% of dibasic acid; The balance of water. Further, the dimethylamine conditioner is selected from one or more of stearamidopropyl dimethylamine and behenamidopropyl dimethylamine, and the content of the dimethylamine conditioner is 2-4%, and further, 2.5-3.5%. Further, the fatty alcohol is selected from one or more of cetyl alcohol and stearyl alcohol, wherein the content of the fatty alcohol is 4.6-8%, and further, 4.6-6.5%. Further, when the fatty alcohol is selected from cetyl alcohol, the content of the cetyl alcohol is 5-6.5%, and when the fatty alcohol is selected from stearyl alcohol, the content of the stearyl alcohol is 5-6.5%. Further, the fatty alcohol is selected from a mixture of cetyl alcohol and stearyl alcohol, wherein the content of the stearyl alcohol is 1.5-1.8%, and the content of the cetyl alcohol is 3.5-4.2%. Further, the dibasic acid is selected from one or more of itaconic acid (an aspergillus fermentation source) and succinic acid, and further, the content of the dibasic acid is 0.3-0.8%. Further, the mass ratio of the dimethylamine conditioner to the dibasic acid is 5-7.5. The mass ratio of the dimethylamine conditioner to the fatty alcohol is 0.5-0.6. Further, the pH value of the hair care composition is 4-6.8, and further, the pH value of the hair care composition is 4.3-6.6. Further, the viscosity of the hair care composition is 80000 to 140000mPa.S. Further, the hair care composition does not comprise lactic acid, L-glutamic acid. The invention also provides a preparation method of the hair care composition, which comprises the following steps, 1) Mixing dimethylamine conditioner and fatty alcohol, heating to 75-85 ℃, and adding the mixture into hot water at 75-85 ℃; 2) Stopping heating, and cooling to below 45deg.C. The invention also provides an application of the hair care composition or the hair care composition prepared by the preparation method of the hair care composition in preparing shampoo, hair conditioner, hair mask or hair care essential oil. The invention also provides a hair conditioner, wherein the hair conditioner composition comprises, by weight, 0.1-99.9% of a hair conditioner additive, 0-5% of cyclopenta-dimethicone, 0-1% of dimethicone, 0-4% of isohexadecane, 0-4% of coco caprylic caprate, 0-1% of phenoxyethanol, 0-1% of a perfume and the balance of deionized water. The invention also provides a hair conditioner, which comprises, by weight, 0.1-99.9% of the hair conditioner composition, 0-2% of cetyltrimethylammonium chloride, 0-1% of phenoxyethanol, 0-1% of perfume and the balance of deionized water. The beneficial effects are that: 1) The invention discloses a dimethylamine conditioner and diacid neutralization technology, which uses diacid and dimethylamine conditioner to neutralize, and solves the technical problems that the viscosity of dimethylamine conditioner is difficult to be improved and the adhesive force is difficult to be improved in actual use. 2) The hair care composition disclosed by the invention can be widely used in washing-free and cleaning-type hair conditioners, so that active ingredients can better stay on
