Description

Technical Field

[0001] The invention relates to the technical field of hair products, in particular to a hair care composition and an essential oil product thereof. Background Art

[0002] Hair care essential oil refers to a type of hair cosmetics that has essential oil added to it and has hair care effects. Traditional hair care essential oils are made of silicone oil, which has a relatively simple effect and generally only plays a basic role in hair care.

[0003] As air pollution becomes increasingly serious, haze particles and particulate matter in the atmosphere are easily adsorbed on the surface of hair, causing increased friction on the hair surface and reduced combing ability of hair; the high temperature in summer and the frequent use of hair dryers and high-temperature flat irons can seriously damage hair scales, making hair dry, brittle, frizzy and difficult to comb; for this reason, consumers' demand for hair care products that can resist particle pollution and thermal radiation is increasing. Summary of the invention

[0004] The present invention provides a hair care composition, which comprises the following components: Polydimethylsiloxane 20%~35%, Caprylic / capric triglyceride 0.5% to 2%, Polydimethylsiloxane alcohol polydimethylsiloxane mixture 15% to 25%, Triolein 0.5% to 3%, Cyclopentasiloxane 35% to 50%, Argania spinosa kernel oil 0.1% to 2%, Butyl octanol salicylate: 0.1% to 2%, Squalane: 0.5% to 3%, The weight ratio of the Argania spinosa kernel oil to squalane is in the range of 1:1.7 to 1:10.

[0005] The above percentages are the weight percentages of each component relative to the hair care composition. The polydimethicone-polydimethicone mixture is composed of polydimethicone and polydimethicone, providing a means of transporting active ingredients. The viscosity of the hair care composition is adjusted, and the hair care composition is smooth and noticeable during use. The added content is preferably 18-20%.

[0006] The polydimethylsiloxane preferably has a content of 28-32%. The polydimethylsiloxane has a kinematic viscosity of 250-400 cts, preferably 350 cts.

[0007] Among them, the butyl octanol salicylate, as a high dielectric constant oil in the hair care composition, can obtain energy from external conditions such as ultraviolet light, effectively resist damage to the hair by air pollution and heat, and at the same time make the composition effectively brighten the hair color. The added content is preferably 0.8% to 1.5%.

[0008] The caprylic / capric triglyceride in the hair care composition can make the hair shiny, smooth and easy to comb, and its added content is preferably 0.8% to 2%.

[0009] The Argania spinosa kernel oil contains a large amount of fatty acids, alcohols, vitamin E and phenolic compounds, which can promote scalp and hair health, increase the gloss of hair, reduce hair tangles, moisturize damaged hair, increase hair gloss, moisturize without being greasy, nourish the skin, and provide long-lasting moisturizing. The added content is preferably 0.3% to 1.5%.

[0010] The semisqualane is a C13-C16 isoparaffin, which has good conditioning properties in the hair care composition and can enhance combing properties; its added content is preferably 0.8% to 2.5%.

[0011] The weight ratio of the Argania spinosa kernel oil to squalane is preferably in the range of 1:3 to 1:6.5.

[0012] The triolein, i.e. triolein, is a highly stable bio-based oil, rich in more than 90% omega-9 unsaturated fatty acids (oleic acid), and helps to strengthen / repair hair fibers, provide luster to hair and smooth frizz in the hair care composition. The content is preferably 0.8% to 2.5%.

[0013] The cyclopentasiloxane can fill the pores on the surface of the hair and form a protective film to make the hair smoother and softer.

[0014] Especially for dry hair, long-term use of CYC products can reduce frizz and split ends. CYC molecules can form hydrogen bonds with water molecules. CYC has good moisturizing properties, which can reduce dryness and fragility of hair and increase the elasticity and softness of hair, preferably to 42% to 48%.

[0015] The present invention also provides a method for preparing the hair care composition, comprising the following steps: The Argania spinosa kernel oil and the dimethicone alcohol dimethicone mixture are mixed in the aforementioned proportions, and then half squalane is added, followed by adding into a reaction kettle, stirring evenly, and cyclopentasiloxane, dimethicone, triolein, caprylic / capric triglyceride, and butyloctanol salicylate are added, and then the material is filtered out.

[0016] Furthermore, the filtration is performed through a 400-mesh filter.

[0017] The viscosity of the hair care essential oil is in the range of 50 to 500 cps. If the viscosity is too high, the greasy feeling and residual feeling will be too obvious during use. If the viscosity is too low, the hair care essential oil will easily roll off during use, which is inconvenient to operate.

[0018] Viscosity: Use METEK BROOKFIELD viscometer, 25°C, 2# rotor, 80 rpm to test the viscosity of the hair care composition. The refractive index of the hair care composition is in the range of 1.40 to 1.43. If the refractive index is too low, the hair will not be bright enough after use. If the refractive index is too high, the hair will be too bright and look too oily after use.

[0019] Beneficial effects of the present invention 1 The butyl octanol salicylate, triolein and argania spinosa kernel oil in the hair care composition prepared by the present application work together to fully absorb the nutrients in the composition and effectively protect against various risk components in atmospheric pollutants. It nourishes the hair, combines maintenance, effectively improves the hair quality, and makes the hair soft and shiny.

[0020] 2 The hair care essential oil prepared by the hair care composition of the present application has good spreadability, can effectively protect damaged hair from heat radiation and dust, and has good storage stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Table 2 Hair care composition formula

[0034]

[0035] Clarity test 70 ml of each example and comparative example was placed in a transparent glass bottle, and the clarity of each sample was scored by visual inspection. Among them: 9-10 points: completely clear; 7-8: clear; 5-6 points: slightly turbid; 3-4 points: turbid; 1-2 points: severely turbid. The clarity results are shown in Table 3, and the photos of Example 3 and Comparative Example 1 are shown in Table 3. Figure 1 Table 3 Clarity results Example 1 Example 2 Example 3 Example 4 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Comparative Example 6 Comparative Example 7 Clarity 7 8 9 9 2 9 9 9 9 / / Among them, in Comparative Example 1, due to the poor miscibility of Argania spirosa kernel oil and the mixture of polydimethylsiloxane and polydimethylsiloxane alcohol, the system was turbid. The inventor unexpectedly found that by adding semisqualane to the system and adjusting the weight ratio of semisqualane to Argania spirosa kernel oil, the compatibility of the system can be increased and a clear and transparent system can be obtained again. When the amount of semisqualane added is small, such as 1:1, the system is still turbid. When the weight ratio reaches 1:1.7, the system is clear.

[0036] However, as in Comparative Example 2, if too much squalane is added to the system, the viscosity of the composition will be reduced by more than 30%, so that the adhesion of the product on the hair is reduced and the effect of the hair care composition cannot be exerted.

[0037] Efficacy test: 1. Dry combing Test instrument: Hair smoothness tester model EMIC DL-500 1. Wash the hair with shampoo and blow dry it, then balance it at (23±2)°C and relative humidity (60±10)% for 1 hour. Stretch the hair at a speed of 300mm / min and displace 200mm. Take the load value between 100-200mm to test the basic combing work of the hair. 2. Wash your hands again, take 0.3 g of the composition on the palm, rub it evenly, and then apply the hair care composition of Examples 1-4 and Comparative Examples 3-7 on the hair of the experimental group with the palm to make the hair care composition evenly wrapped on the hair. Repeat the above steps to partially test the combing work of the hair after application, and calculate the dry combing work.

[0038] Dry combing work reduction percentage = (basic combing work - combing work after application) / basic combing work The greater the dry combing differential work, the better the dry combing performance of the hair. In order to reduce the measurement error caused by different hair bundles, the same hair bundle was tested 3 times and the average value was taken.

[0039] (ii) Gloss test: Test instrument: Multifunctional analyzer, model Cutometer dual MPA 580 Test conditions: After washing the hair with shampoo and drying it, balance it at (23±2)°C and relative humidity (60±10)% for 1 hour, wash your hands, take 0.3g of the composition on the palm, rub it evenly, and then apply the hair care composition on the hair with the palm, and apply the hair care compositions of Examples 1-4 and Comparative Examples 3-6 on the hair of the experimental group with the palm, and after the hair care compositions are evenly wrapped on the hair for 1 hour, use the Skin-Glossymeter probe to test the glossiness of the hair; the larger the test data, the better the glossiness.

[0040] (III) Anti-particle pollution test Wash your hands, take 0.3 g of the composition on your palms, rub them evenly, and then apply the hair care compositions of Examples 1-4 and Comparative Examples 3-6 on your hair with your palms. The samples were then placed outdoors for 72 hours to test the anti-particle pollution performance of the applied hair care composition.

[0041] (1) Comparison of pollutant particles remaining on hair strands Use an electronic balance to measure the weight of the sample before placing it outdoors, and the weight of the sample after 72 hours, and calculate the weight difference before and after placement. The smaller the weight difference between the sample before and after, the less particles remain on the hair.

[0042] (2) Dry combing test: According to the dry combing performance test steps in (I), test the dry combing performance before and after being placed outdoors for 72 hours. Calculate the combing work difference Percentage increase in dry combing work = (combing work after test - initial combing work) / initial combing work (3): Gloss test According to the test steps in (ii), test the glossiness of the sample after 72 hours.

[0043] (IV) Thermal radiation test Wash your hands, take 0.3g of the composition of Examples 1-4 and Comparative Examples 3-6 on your palms, rub them evenly, and then apply the hair care composition on different hair bundles of the experimental group with your palms to make the hair care composition evenly wrapped on the hair of the experimental group. Then, use a 180°C clamp to stretch the hair bundles from head to tail for 10 times. (1) Hair scale damage test under high temperature: Observe the degree of damage to the hair scales after heat treatment under a microscope. According to the degree of damage to the hair scales, subjective scores are given, ranging from 1 to 10 points (1 point is the lightest damage, 10 points is the most severe damage). 7-8: severe damage, 5-6: damage, 3-4: slight damage, 1-2: no damage (2) Dry combing test at high temperature: 1. Test the basic combing skills before using the hair splint; 2. Test the combing performance of the hair after using the hair clip. Test the combing work before and after high temperature treatment with splints and calculate the difference in combing work Increase in dry combing work = (combing work after using the splint - basic combing work) / basic combing work (3) Gloss test: According to the test steps in (ii), measure the glossiness of the hair after heat treatment. (V) Sensory test 20 people aged 25-35 with long hair were selected. After washing their hair and before blow-drying, according to the amount of hair, about 0.5-1 g of the hair care composition was applied to the palm of the hand. After rubbing evenly, the hair care composition was applied to the hair with the palm of the hand so that the hair care composition was evenly wrapped on the hair. After one use, the hair care composition was rated according to the user's feeling.

[0044] The specific application comfort rating includes: (1) Evaluation of greasiness: (1-2: heavy greasiness, 3: moderate greasiness, 4-5: moderate greasiness) (2) Evaluation of spreadability: (1-2: difficult to spread, 3: moderate spreadability, 4-5: easy to spread) (3) Moisturizing rating: (1-2: average moisturizing, 3: moderate moisturizing, 4-5: good moisturizing) (4) Dirt resistance: (1-2 means poor dirt resistance, 3 means average dirt resistance, 4-5 means good dirt resistance) Table 4 Efficacy test results

[0045] In Comparative Example 3, if the content of polydimethylsiloxane is too high, the hair care composition leaves a strong residual feeling on the hands when applied.

[0046] Comparative Example 4 If the amount of the polydimethylsiloxane and polydimethylsiloxane alcohol mixture is too much, the hair care composition will be too smooth, and the residual feeling on the hair will be heavy, resulting in a poor feeling during use.

[0047] Comparative Example 5: If the amount of cyclopentasiloxane is too much, the hair care composition has poor smoothness and poor dry combing properties.

[0048] If the comparative example 6 does not contain active ingredients, the heat radiation and dust prevention effects are poor, and the hair scales cannot be protected. After heat radiation and dust treatment, the neatness of the hair scales is poor, and many pollutant particles remain on the hair.

[0049] The above specific implementations have been described in detail for the present invention, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
