Description

Technical Field

[0001] The invention belongs to the technical field of hair care sprays, and in particular relates to a hair care spray with a water-oil dual phase and a preferred oil phase formula and a preparation method thereof. Background Art

[0002] Hair is an important part of the human body. It not only affects a person's appearance, but also reflects a person's health status to a certain extent. With the improvement of people's living standards and the pursuit of beauty, more and more people are beginning to pay attention to hair care. Good hair care can keep hair healthy, shiny and smooth, and can also enhance personal self-confidence and charm. In the past, people mainly used traditional hair care products such as shampoo and conditioner to care for their hair. However, these products often have some limitations. For example, shampoo mainly only plays the role of cleaning hair and is difficult to provide hair care effects; while traditional conditioners are mainly based on cationic surfactants, supplemented with moisturizers, fat-filling agents, emulsifiers and other ingredients to improve hair care effects and performance, and thickeners are used to form a polymer film on the surface of the hair to play a hair care role. Therefore, after using the conditioner, it is necessary to rinse the hair, and the hair will feel heavy and sticky, which affects the user experience and comfort; and although general traditional conditioners claim to have a smooth and moisturizing effect, they often have poor effects and cannot achieve the purpose of smoothing and moisturizing the hair.

[0003] Therefore, in order to solve the problem that hair is sticky, difficult to comb and dry after treatment with traditional conditioners, providing a water-oil two-phase hair spray that can solve such problems has important market significance and application value. Summary of the invention

[0029] Beneficial effects of the present invention:

[0030] (1) The raw materials constituting the aqueous phase of the present invention include hydroxypropyl trimethyl ammonium chloride hyaluronic acid, which has a high affinity and strong hydrating effect. The hydroxypropyl trimethyl ammonium chloride hyaluronic acid can penetrate deep into the hair core to repair damaged hair and thus play a role in smoothing the hair scales. In addition, the hydroxypropyl trimethyl ammonium chloride hyaluronic acid can also be deposited on the hair to form a film, which has a strong strengthening and repairing effect, thereby making the hair softer and more lustrous. Polylysine, which has a strong hygroscopicity, is selected to absorb and lock in a large amount of water to keep the hair moisturized. Polyols are selected to reduce the viscosity of the system, which helps to keep the hair light and moisturized after use. That is, the hydroxypropyl trimethyl ammonium chloride hyaluronic acid, polylysine and polyols selected in the present invention can respectively repair damaged hair, keep the hair moisturized and reduce the viscosity of the system, and synergistically reduce the friction between the hair prepared by the hair care spray of the present invention and make the hair light, soft and easy to comb.

[0031] (2) PPG-3 benzyl ether myristate containing benzyl, methyl side chain and fatty chain alkoxy groups is added to the raw materials constituting the oil phase of the present invention to improve the dispersibility of the finished product, enhance the fluidity of the finished product, and improve the skin feel. The benzyl part of the benzyl part can give the product better compatibility with other raw materials. On this basis, caprylic / capric triglyceride with strong affinity for hair is added to provide moisture to the hair as a moisturizing factor. Coconut oil alcohol-caprylic acid ester / capric acid ester is added to form a smooth film on the surface of the hair to moisturize the hair. Trimethylolpropane isostearate is added to increase the smoothness of the hair. Therefore, the hair care spray prepared in this way has the effect of preventing the hair from being dry, dehydrated and rough.

[0032] (3) The plant oil selected in the present invention generally has moisturizing and soothing effects, does not irritate the scalp when used, and can assist other ingredients in the system to strengthen the effect of preparing the hair care spray to prevent hair from drying and reduce friction between hair.

[0178] Test Example 1

[0179] Friction test of hair bundle after washing:

[0180] (1) Test material: flat hair bundle (3.0 g, 15 cm, normal hair bundle);

[0181] Testing instruments: TSH series of hair product efficacy multifunctional tester, electronic balance;

[0182] Test conditions: constant temperature and humidity (21°C, 50% RH);

[0183] Test basis: After applying the hair sprays prepared in Examples 1-12 and Comparative Examples 1-3 to the hair bundles, the friction force was tested. The maximum force required for combing Force Max [N] and the average force (with and without the hair ends) [N] were tested. The smaller the value, the easier the hair is to comb.

[0184] (2) Test process: Friction test

[0185] 1) Randomly select 4 identical flat hair bundles (3.0g, 15cm, normal hair bundles), wash the hair bundles, wipe off excess water, apply 0.1g / g hair sample to each hair bundle, treat for 1min, rinse with running water for 30s, and operate once in total. Dry naturally in a constant temperature and humidity environment (21℃, 50%RH) and balance for 24 hours;

[0186] 2) Use a hair combing instrument to test the friction work of the hair bundle, once for each bundle, and record the friction work value;

[0187] 3) Use EXCEL to perform descriptive statistics of the data, including mean force and maximum force;

[0188] The final test results are shown in Table 1.

[0189] Table 1 Friction test statistics

[0190]

[0191]

[0192] As can be seen from Table 1, the friction force of Example 1-3 group is the largest, followed by Example 7-8 group, Example 10-12 group, Comparative Example 1-3 group, and Example 4-6 group. This indicates that the friction force of Example 7-8 group, in which hydroxypropyl trimethyl ammonium chloride hyaluronic acid and polylysine are added to the aqueous phase, is less than that of Example 1-3 group, but greater than that of Example 4-6 group, in which the optimized oil phase formula and hydroxypropyl trimethyl ammonium chloride hyaluronic acid and lysine are added. The friction force of Example 10-12 group, in which the optimized oil phase and hydroxypropyl trimethyl ammonium chloride hyaluronic acid and polylysine are added to the aqueous phase, is the smallest, and the effect is the best. Therefore, it is believed that the hair care spray product can improve the phenomenon of hair tangling and difficulty in combing during the combing process, thereby achieving the effect of smoothing hair; by comparing Example 4-6 with Example 7-8, it is believed that the oil phase can further improve the hair smoothing effect on the basis of adding hydroxypropyltrimethylammonium chloride, hyaluronic acid and lysine to the aqueous phase; by comparing Example 4-6 with Example 10-12, it is believed that the aqueous phase can further improve the hair smoothing effect on the basis of adding PPG-3 benzyl ether myristate, caprylic / capric triglyceride, coconut oil caprylate / caprate, trimethylolpropane isostearate and vegetable oil to the oil phase.

[0193] Comparative Examples 1-3 certified the synergistic effect of hydroxypropyltrimethylammonium chloride hyaluronic acid, polylysine and polyols in the aqueous phase of the system, and determined that the hydroxypropyltrimethylammonium chloride hyaluronic acid, polylysine and polyols selected in the present invention can respectively repair damaged hair, keep hair moisturized and reduce the viscosity of the system, and synergistically reduce the friction between the hair prepared by the hair care spray of the present invention and have the effect of being light, soft and easy to comb.

[0194] Test Example 2

[0195] Hair bundle moisturizing experiment after washing:

[0196] (1) Test material: human hair bundle;

[0197] Testing instruments: dryer, electronic balance, weighing dish;

[0198] Test reagents: hair spray prepared in Examples 1-12 and Comparative Examples 4-7, AES 14% solution;

[0199] Test conditions: constant temperature and humidity (21°C, 50% RH);

[0200] Test basis: Different moisturizer molecules have different forces on water molecules, and their ability to absorb and retain moisture is also different. The moisturizing effect of the sample on the skin and hair can be tested based on the water loss rate of the sample.

[0201] (2) Test process: Moisture weighing method

[0202] 1) Wash and dry the weighing dish to constant weight and number it, and balance the dryer;

[0203] 2) Select a flat hair bundle (2.5 g, 15 cm, healthy hair bundle), perform basic cleaning with 14% AES solution, and maintain equilibrium at constant temperature and humidity (21° C., 50% RH) for 24 hours;

[0204] 3) Randomly select hair bundles that have been washed and balanced with 14% AES solution, and spray the hair care sprays prepared in Examples 1-12 and Comparative Examples 4-7 on each hair bundle. The spraying method is: hold one end of the hair bundle, spray the hair care spray nozzle at a 45-degree angle to the middle of the hair bundle and 10 cm away from the hair bundle, and spray the front and back of the hair bundle once each.

[0205] 4) Place all weighing dishes on the balanced drying oven partitions to ensure air circulation above and below the partitions. After leaving them for a period of time (0h, 2h, 4h, 6h, 8h), take them out and weigh them, and calculate the moisture retention rate W2 (%).
