Description

Technical Field

[0001] The present invention belongs to the technical field of hair care products, and in particular relates to a light repairing protein hair care composition and application thereof. Background Art

[0002] Hair proteins are sensitive to heat, acid, and alkali, and can stretch and deform under mechanical forces. Hair is damaged to varying degrees during combing, washing, perming, and dyeing. This damages the hair's molecular structure, diminishing its luster, causing it to become dry and prone to split ends, while also reducing its elasticity and strength, making it brittle and easily breakable.

[0003] CN107823057A discloses a white agarwood hair conditioner and its preparation method. The white agarwood hair conditioner comprises an emulsifier, xanthan gum, sea buckthorn oil, sericin, white agarwood essential oil, and bamboo extract water. The white agarwood hair conditioner has a pleasant fragrance, provides nutrients needed for hair, repairs and strengthens hair, and promotes hair cell metabolism. After washing, hair becomes soft, smooth, and shiny, and it resists damage from external factors, providing excellent conditioning and repairing effects.

[0004] CN109771366A discloses a moisturizing and repairing hair conditioner and its preparation process, which is prepared by mixing component A and component B in a mass ratio of 1:2; the component A is prepared by fermenting 20-30 parts by weight of angelica sinensis, 10-15 parts by weight of polygonum multiflorum, 20-30 parts by weight of gallnut, 5-10 parts by weight of glossy privet fruit, 4-8 parts by weight of figwort, and 3-6 parts by weight of cassia seed with a composite bacterial agent; the component B is prepared by fermenting 15-20 parts by weight of enzymatic hydrolyzed aloe powder, 10-15 parts by weight of hydrolyzed keratin, 12-16 parts by weight of oat beta-glucan, 8-12 parts by weight of complex amino acids, 3-6 parts by weight of sodium polyglutamate, 5-9 parts by weight of cetearyl stearic acid, and 0.5-1 part by weight of vitamins. The hair conditioner is safe and non-irritating, easily absorbed by the scalp, can repair damaged hair scales, solve the problems of dry and dull hair, and can supplement the nutrients needed by the hair to promote hair growth.

[0005] Existing hair care products still need to be further improved. Based on this, there is an urgent need to develop a light repair protein hair care product. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a light repair protein hair care composition and its application. The hair care composition provided by the present invention has safe and non-irritating ingredients, and the components are synergistically compatible, and has excellent hair care effects.

Avocado butter, rich in fatty acids and antioxidants, deeply nourishes hair, repairs damage, enhances shine, and reduces frizz. Macadamia nut seed oil, with its high penetrating properties, effectively improves dry, brittle hair while forming a protective film to lock in moisture. Coleus oil, rich in vitamins, prevents hair loss, promotes hair growth, prevents breakage, and improves hair quality.

[0010] The hair care composition provided by the present invention has safe and non-irritating ingredients. The hydrolyzed rice protein, avocado oil, macadamia seed oil and scutellaria baicalensis oil have a synergistic effect and work together to exert excellent hair care effects of repairing, nourishing, preventing hair breakage, moisturizing, anti-static and softening hair.

[0126] Test Case

[0127] (1) Hair bundle cleaning: Take a human ex vivo hair bundle, Asian hair, with a length of 27±0.5 cm, a width of 2.5±0.1 cm, and a weight of 6±0.5 g; apply 14% SLS solution for 1 minute, using the same hand gesture as milking a cow; comb the hair thoroughly to evenly distribute the 14% SLS solution on the surface of the hair bundle, and let it stand; rinse with warm water for 1 minute (water temperature 37°C, water flow rate 75 mL / s, water hardness 80 ppm); comb the hair thoroughly and let it dry.

[0128] Hair damage: Prepare a chemical treatment solution (freshly prepared for immediate use) by mixing 119 g of 30% hydrogen peroxide solution with 91 g of water and adjusting the pH to 9.5 with 25% ammonia. Soak the cleaned hair in 1 L of water for 30 minutes. Apply the chemical treatment solution evenly to the hair, ensuring that all hair strands are immersed in the solution. Leave the solution at 21°C for 30 minutes. Rinse with tap water for 3 minutes to ensure that the solution is completely removed. Repeat this process once, soaking the treated hair in 1 L of water for 60 minutes, then rinse thoroughly. Place the hair strands in a constant temperature and humidity chamber at 21°C and 50% RH.

[0129] (2) The hair conditioner provided in Examples 1-11 and Comparative Examples 1-4 (0.25 mL / g hair bundle) was applied to the treated hair bundles. The conditioner was evenly applied with fingers from root to tip for 60 seconds and then rinsed. A control group was prepared by applying a 14% SLS solution (0.25 mL / g hair bundle) and rubbing the hair evenly from root to tip for 2 minutes and then rinsing. The hair bundles treated with the samples were placed in a constant temperature and humidity chamber at 21°C and 50% RH until ready for testing. Six replicates were set for each sample group in each test, and only one test was performed on each sample group.

[0130] (3) ① Use the electronic balance PRACTUM224-1CN to record the mass of the hair bundle before use and 6 hours after use, and calculate the mass change rate of the hair bundle (%) = [(mass of the hair bundle after use - mass of the hair bundle before use) / mass of the hair bundle before use] × 100%. The larger the value, the better the moisturizing effect of the sample; ② Use a plastic comb to comb the hair bundle 10 times and use the hair volume test system BOLERO Buffle test sample (each hair bundle is combed and imaged within 20 seconds) before use and after 12 hours of use, calculate the hair bundle fly area, calculate the hair bundle fly area change rate (%) = [(hair bundle fly area after use - hair bundle fly area before use) / hair bundle fly area before use] × 100%, the smaller the value, the better the antistatic effect of the sample; ③ first use a wide-tooth comb to unclog the hair bundle (broken hair at this time is not counted in the total number of broken hair), then use a hair combing machine SIRTAKI to automatically comb at a uniform speed of 10,000 times, combing speed of 40 / min, collect broken hair and count, then use an automatic hair combing machine to comb at a uniform speed of 10,000 times (accumulative 20,000 times), combing speed of 40 / min to collect broken hair and count, record the total number of broken hair roots before use and after 72 hours of use, calculate the broken hair root number change rate (%) = [(total number of broken hair roots after use - ④ Use the multi-function hair tester Fibra.one to test the friction and wet combing properties of the hair bundles before use and 72 hours after use: test the friction roller from the roots to the ends of the hair once, and then test it in the opposite direction from the ends to the roots of the hair, and calculate the change rate of the total friction work of the hair bundle (%) = [(total friction work of the hair bundle after use - total friction work of the hair bundle before use) / total friction work of the hair bundle before use] × 100%. The smaller the value, the better the nourishing and repairing effect of the sample; soak the hair bundle with water and control its humidity at 55%, test the total wet combing work of the hair bundle, and calculate the change rate of the total wet combing work of the hair bundle (%) = [(total wet combing work of the hair bundle after use - total wet combing work of the hair bundle before use) / total wet combing work of the hair bundle before use] × 100%. The smaller the value, the better the softening effect of the sample.

[0131] (4) The test results are shown in Table 1. The hair care composition and conditioner ingredients provided by the present invention are safe and non-irritating, and have excellent hair care effects of repairing, nourishing, preventing hair breakage, moisturizing, anti-static, and smoothing. Hydrolyzed rice protein, avocado oil, macadamia seed oil, and scutellaria oil have a synergistic effect, hydrolyzed keratin, sericin, cocodimonium hydroxypropyl hydrolyzed keratin, and argania spinosa kernel oil have a synergistic effect, and alpine edelweiss flower / leaf extract, camellia seed oil, royal jelly extract, and grapefruit peel extract have a synergistic effect. The components work synergistically to exert excellent hair care effects.
