Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and in particular to a conditioning and fluffy composition and application thereof in personal care products. Background Art

[0002] The hair shaft can be divided into three layers: the cuticle, cortex and medulla, and its main component is keratin. The outermost layer of the cuticle is the outer β-layer containing 18-methyl ethyl ester, which is hydrophobic and plays a role in protecting the hair from protein loss. In real life, urban environmental pollution, ultraviolet radiation, hair perming and dyeing, combing and hot drying can cause different degrees of damage to the hair, making the hair frizzy and difficult to comb, dry and dull, split and easy to break, etc.

[0003] In order to solve the problem of damaged hair and difficulty in combing, cationic polymer conditioning agents such as polyquaternium-10 and guar hydroxypropyltrimonium chloride as well as silicone oil, vegetable oil and other fats are usually added to shampoo. Silicone oil, vegetable oil and other fats have a hydrophobic effect, which can improve the hydrophilicity and frizziness of hair. Cationic polymer conditioning agents can help silicone oil and other fats to deposit on the hair, increase the utilization rate of fats and improve combing performance. This is mainly because cationic polymers can form water-insoluble composite salt floc colloids with surfactants during the shampooing and flushing process. The precipitated composite salt floc colloids can carry silicone oil and other fats, allowing the fats to be better deposited on the hair.

[0004] Although adding cationic polymer conditioning agents and oils to personal care products solves the problem of frizzy hair combing, long-term use will lead to the accumulation of oils and compound salt floc colloids, causing the hair to gradually become flat and greasy. This is mainly because the compound salt floc colloids formed by the commercially available cationic polymers with good conditioning effects have a strong binding strength. After being adsorbed on the hair, the compound salt floc colloids are not easy to spread, the film formed is uneven, and it is not easy to be washed off again. Therefore, long-term use will lead to the accumulation of compound salt floc colloids and oils, resulting in flatness and greasiness.

[0005] Therefore, it is necessary to develop a personal care product that has a good conditioning effect without excessive deposition and a greasy and heavy feeling. Summary of the invention

[0132]

[0133]

[0134] 2) Combing test:

[0135] The combing test is a test of the combing force or combing work of isolated human hair bundles using a hair bundle comber. It is used to evaluate the effect of personal care products on improving damaged hair bundles.

[0137] 1. Hair bundle selection: select hair bundles that have not been tested and conduct combing test on them. Select hair bundles with no obvious difference in combing force or combing work for testing of application examples. The hair bundles used for application testing are divided into control group and test group, with 3 hair bundles in each group for each application test.

[0138] 2. Hair bundle pretreatment: Wash the hair bundle with clean water at a temperature of 38±1°C. After washing, dry it in a constant temperature and humidity chamber for use. The conditions of the constant temperature and humidity chamber are set at: 23±0.5°C, 60±5%RH.

[0139] 3. Baseline wet hair combing test (W0): The test group hair bundles are fully wetted with running constant temperature clean water, and 0.2 grams of K12 solution with a solid content of 8% is evenly applied to the surface of the hair bundles at a dosage of 0.2 grams per gram of hair bundles. The application time is about 30 seconds, and it is left to stand for about 1 minute, and then rinsed for about 30 seconds. The treated hair bundles are fixed in the test position and the combing cycle test is carried out.

[0140] 4. Baseline dry hair combing test (D0): The hair bundle after the wet hair test is placed in a constant temperature and humidity chamber for more than 4 hours, taken out and fixed in the test position, and the combing cycle test is performed. The hair bundle after the test is placed in a constant temperature and humidity chamber for use.

[0141] 5. Sample wet hair combing test (Wx): Wet the hair bundle that has completed the baseline combing test with running constant temperature clean water, apply 0.2 grams of sample per gram of hair bundle or the amount in accordance with the sample usage method evenly on the surface of the hair bundle for about 30 seconds, let it stand for about 1 minute, and then rinse for about 30 seconds or skip rinsing. Fix the treated hair bundle in the test position and perform the combing cycle test.

[0142] 6. Sample dry hair combing test (Dx): After the wet hair test, the hair bundle is placed in a constant temperature and humidity chamber for more than 4 hours, taken out and fixed in the test position, and a combing cycle test is performed.

[0143] Calculation of combability improvement effect: Wet hair combability improvement = (W0-Wx) / W0*100%; Dry hair combability improvement = (D0-Dx) / D0*100%.

[0144] The combing test results of the shampoo application example samples are shown in Table 3.

[0151] 3) Comprehensive performance evaluation of product conditioning and fluffyness:

[0152] When using the product, users will pay attention to both the fluffy effect of the product and the wet hair combing effect and the dry hair combing effect of the product. In order to better evaluate the comprehensive performance of the product, the fluffy degree, wet hair improvement degree and dry hair improvement degree of the product after five shampooing are normalized. The normalized data are shown in Table 5, and the comprehensive performance index F of shampoo product conditioning and fluffyness is calculated according to the following formula.

[0153] Conditioning and fluffy comprehensive performance index F = (P × 0.4 + S × 0.3 + G × 0.3) × 100;

[0154] Among them, P is the normalized data of fluffiness using 5 times, S is the normalized data of wet hair improvement using 5 times, and G is the normalized data of dry hair improvement using 5 times.

[0155] The larger the comprehensive conditioning and fluffy performance index F is, the better the comprehensive conditioning and fluffy performance of the product is.

[0156] Application example conditioning fluffy comprehensive performance index F as shown in Table 5, Figure 2 shown.

[0159] 4) Human sensory evaluation of hair spray:

[0160] Thirty-two long-haired women were recruited to use the skin care spray and rate the smoothness of the application process, the feeling of freshness, the smoothness of dry hair, and the fluffiness of dry hair.

[0161] The human sensory evaluation of the hair spray is shown in Table 6.

[0163]

[0164] 5) Inhibition zone test:

[0165] All reagents and equipment used in the experiment were sterilized by high pressure steam in advance and then cooled to room temperature for use. 20 mL of sterilized nutrient agar culture medium was transferred to a glass plate, cooled naturally, and used after solidification.

[0166] Use sterile saline to mix 1 mL of 10 8 ~10 9 CFU mL -1 Nutrient broth of microorganisms (Staphylococcus aureus, Escherichia coli, Salmonella, Malassezia furfur) was diluted to 10 6 CFUmL -1 , make a bacterial suspension. Take 100μL of bacterial suspension and spread it evenly on the nutrient agar medium, gently place the Oxford cup, and add 150μL of sample into the cup. Place all the culture plates in a 4℃ environment for 12h, then take them out and return to room temperature.

[0167] Finally, it was placed at (36±1)℃ and cultured for 1 day, and the size of the inhibition zone was accurately measured.

[0168] The inhibition zone results of the hair spray application example are shown in Table 7.
