Description

Technical Field

[0001] The invention relates to a hair conditioning and fluffy composition, belonging to the technical field of cosmetics, and in particular to a hair conditioning and fluffy composition and application thereof in shampoo 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 liquid oils such as silicone oil and vegetable oil are usually added to shampoo. Silicone oil, vegetable oil and other oils have a hydrophobic effect, which can improve the hydrophilicity and frizziness of hair. Cationic polymer conditioning agents can help silicone oil and other oils to deposit on the hair, increase the utilization rate of oils 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 oils, allowing the oils 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 cause the liquid oil and compound salt floc colloid to precipitate and accumulate, and the hair will gradually become flat and greasy. This is mainly because the compound salt floc colloid formed by the commercially available cationic polymer with good conditioning effect has a high binding strength. After the compound salt floc colloid is adsorbed on the hair, it is not easy to spread, and the film formed is sticky and uneven. During long-term use, the accumulation of sticky and uneven floc and liquid oil will bring a heavy and sticky feeling.

[0005] Therefore, there is a need to develop a shampoo product that has good conditioning effects while not causing heaviness and stickiness during long-term use. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, the primary purpose of the present invention is to provide a composition having a conditioning and fluffy effect which has a good conditioning effect and does not cause heaviness and stickiness after long-term use, and a preparation method thereof.

[0195] The following are the contents of the efficacy test examples including performance tests.

[0196] 1. Fluffiness test:

[0197] In order to reduce the interference of human body in the test result of fluffiness in blowing, combing and living habits, the fluffiness test method of the present invention uses hair bundles for testing. The specific operation method is as follows:

[0198] 1. Pre-cleaning: Wash the hair with 5% SLES solution once, and hang it in a constant temperature and humidity environment to dry overnight for later use;

[0199] 2. Pre-treat the hair bundles with 1% artificial sebum ethanol solution, dry them, do not comb them, and take photos of the hair bundles under this condition in a homemade light box in the laboratory (4 photos per bundle);

[0200] 3. Import the photo into Image Pro image analysis software and calculate the fluffy value (Aera / Pixel) A0 of each strand of hair;

[0201] 4. Wash the hair with the shampoo to be tested, using 0.6 ml per hair, rubbing for 30 seconds, and rinsing for 30 seconds;

[0202] 5. Hang the washed hair in a constant temperature and humidity room (Rh55%, 22℃) to dry overnight;

[0203] 6. Keep the hair bundle in the state of drying, do not comb it, and take photos of the hair bundle under this condition in a homemade light box in the laboratory (4 photos per bundle); Figure 1-2 shown.

[0204] 7. Import the photo into Image Pro image analysis software and calculate the fluffy value (Aera / Pixel) Ax of each strand of hair.

[0205] 8. Calculate the bulkiness using the following formula:

[0206]

[0207] The test results of the fluffiness value of the sulfate shampoo examples and comparative examples containing the conditioning and fluffy composition of the present invention are shown in Table 2. Figure 1 As shown:

[0208] Table 2 Test results of the bulkiness of sulfate shampoo examples and comparative shampoo

[0209]

[0210] From the data in Table 2, it can be seen that the fluffiness improvement of the examples containing the conditioning and fluffy composition of the present invention is much higher than that of the comparative examples.

[0211] The test results of the fluffiness values ​​of the non-sulfate shampoo examples and comparative examples containing the conditioning and fluffiness composition of the present invention are shown in Table 3. Figure 2 As shown:

[0212] Table 3 Test results of the bulkiness of non-sulfate shampoo examples and comparative shampoo

[0213]

[0214] From the data in Table 3, it can be seen that the fluffiness improvement of the examples containing the conditioning and fluffy composition of the present invention is much higher than that of the comparative examples.

[0215] 2. Combing test:

[0216] 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.

[0217] The specific steps of the combing test of the product of the present invention are as follows:

[0218] 1) Hair bundle selection: select hair bundles that have not been tested and perform a combing test on the hair bundles. 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 a control group and a test group, with 3 hair bundles in each group for each application test.

[0219] 2) Hair bundle pretreatment: Wash the hair bundle with clean water at a temperature of 38±1°C, dry it in a constant temperature and humidity chamber for later use, and the conditions of the constant temperature and humidity chamber are set at 23±0.5°C and 60±5%RH.

[0220] 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 cleaning solution per gram of hair bundles are evenly applied on the surface of the hair bundles for about 30 seconds, 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.

[0221] 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.

[0222] 5) Sample wet hair combing test (W1): Wet the hair bundle that has completed the baseline combing test with running constant temperature clean water, and evenly apply 0.2 grams of sample per gram of hair bundle or the amount in accordance with the sample usage method 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.

[0223] 6) Sample dry hair combing test (D1): 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 a combing cycle test is performed.

[0224] 7) Calculation of combing improvement effect: Wet hair combing improvement degree = (W0-W X ) / W0*100%; Dry hair combing improvement = (D0-D X ) / D0*100%.

[0225] The combing forces W0, D0, WX, and D0 of the application example samples after washing the hair bundle once and washing the hair bundle five times respectively X The data are shown in Tables 4 and 5.

[0226] Table 4 Combing force data of sulfate shampoo examples and comparative examples

[0227]

[0228] In Table 4, W1 and W5 of the examples and comparative examples are much smaller than W0, and D1 and D5 are much smaller than D0, which proves that both the examples and comparative examples can improve the combing performance of the hair bundle. However, the combing force of the examples is smaller than that of the comparative examples, which indicates that the conditioning composition of the present invention has a good combing improvement effect in sulfate system shampoo.

[0229] Table 5 Combing force data of non-sulfate shampoo examples and comparative examples

[0230]

[0231] In Table 5, W1 and W5 of the examples and comparative examples are much smaller than W0, and D1 and D5 are much smaller than D0, which proves that both the examples and comparative examples can improve the combing performance of the hair bundle. However, the combing force of the examples is smaller than that of the comparative examples, which indicates that the conditioning composition of the present invention has a good combing improvement effect in non-sulfate system shampoo.

[0232] In order to more intuitively show the improvement degree of dry hair combing property and wet hair combing property of the composition of the present invention in the sulfate system and the non-sulfate system, the improvement degree of combing property is calculated according to the combing improvement calculation formula, and the improvement degree of combing property is shown in Table 6:

[0233] Improvement in wet hair combing S X =(W0-W X ) / W0*100%;

[0234] Improvement in dry hair combing G X =(D0-D X ) / D0*100%.

[0235] Table 6 Combability improvement of hair bundle after one wash and five washes

[0236]

[0237] It can be seen from Table 6 that the modification degree of the dry combing and wet combing of the hair bundle in the examples is much higher than that in the comparative examples, which indicates that the conditioning composition of the present invention can significantly improve the conditioning effect of the product.

[0238] 5. Comprehensive performance evaluation of product conditioning and fluffyness:

[0239] 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. In order to better evaluate the comprehensive performance of the product, the comprehensive performance index F of shampoo product conditioning and fluffyness is calculated according to the following formula.

[0240] Fluffy conditioning comprehensive performance index F X =(I X ×0.4+S X ×0.3+G X ×0.3)×100;

[0241] The larger the comprehensive conditioning and fluffy performance index F is, the better the comprehensive conditioning and fluffy performance of the product is.

[0242] The comprehensive performance index F of conditioning and fluffing of the application example is shown in Table 7.

[0243] Table 7 Application example conditioning fluffy comprehensive performance index F

[0244]

[0245]

[0246] From Table 7, Figure 3-4 It can be seen that the conditioning and fluffing performance of the embodiment are much higher than those of the comparative example, which shows that the composition of the present invention has excellent comprehensive conditioning and fluffing performance.
