Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and in particular relates to a fluffy oil-control composition and a preparation method and application thereof. Background Art

[0002] As people's material living standards improve, hair styling products play an increasingly important role in people's daily lives, carrying people's pursuit of external image. Hair styling is becoming more and more diverse for different age groups, different hair qualities, different hair lengths, different hair shapes, different styling styles, different scenes, etc.

[0003] In recent years, the hair styling market has begun to favor three-dimensional, natural, matte and non-styling effects, that is, the requirements for hair volume, matte and oil control have become more frequent. In order to meet the above needs, hair styling cosmetics that can provide high volume and strong oil control effects have become a very urgent need for consumers.

[0004] At present, the existing technologies mainly have the following directions:

[0005] (1) Adding insoluble powders: Starch and its derivatives, such as corn starch, rice starch, aluminum starch octenyl succinate, etc., mainly achieve the oil control effect by physically absorbing the oil secreted by the scalp. However, when attached to the hair, it can only absorb oil and smooth the hair, but cannot increase the rigidity of the hair or the friction between the hair strands. At the same time, it will increase the burden on the hair, causing the hair to flatten. In addition, due to the large particle size, it may leave unsightly white spots, white flakes, etc. on the hair.

[0006] (2) Adding oil-control active ingredients: niacinamide, PCA zinc, witch hazel extract, lactobionic acid, etc., mainly through biological regulation to control excessive scalp oil secretion. However, it can only play an oil-control role, the onset time is long, and the fluffy and instant oil-control effect is not obvious.

[0007] (3) Adding cationic conditioning agents: Positively charged polymers have a high adhesion to negatively charged hair and can form a thin film on the hair surface. Using the principle of like charges repelling each other, they can increase the volume of the hair. However, due to their large molecular weight, they will increase the burden on the hair and soften the hair, so they cannot achieve a good fluffy and oil-control effect.

[0008] (4) Adding fixatives: polyvinyl pyrrolidone, acrylic acid (ester) / VP copolymer, VP / VA copolymer, etc., mainly to maintain the hair shape and prevent the hair from flattening after the fixative forms a film on the hair surface to achieve a fluffy effect. However, it can only stick the hair together, easily forming strands and looking unnatural, and it cannot increase the rigidity of the hair or the friction between the hair strands. The fluffy effect is not obvious and the fluffy effect lasts for a short time.

[0009] Since most of the existing products on the market have not yet gotten rid of the shortcomings of being too single in function and having insignificant effects, and are unable to meet consumers' increasingly strong styling needs, it is of great significance to provide an oil-control and fluffy product that can effectively control excessive secretion of scalp oil and increase the volume of hair. Summary of the invention

[0010] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a fluffy oil-control composition and a preparation method and application thereof.

[0011] To achieve the above objectives, the technical solutions adopted by the present invention include:

[0012] In a first aspect, the present invention provides a fluffy oil-control composition, comprising the following components in percentage by mass: 0.05-5% fumed silica, 0.05-5% sodium shale oil sulfonate, 0.001-1% capryloyl glycine, 0.6-8% moisturizer, 1-75% organic solvent, 0.2-2% preservative and the balance water.

[0013] The fumed silica of the present invention is prepared from silica by a gas phase method, while the silica commonly used in hair products on the market is mostly prepared by a precipitation method. The two silica preparation processes are different, and the structures and properties are also completely different. The fumed silica is based on silicon chloride as a substrate. After being hydrolyzed and condensed into single silica particles by a hydrogen-oxygen flame at high temperature in a combustion furnace, spherical particles of 7 to 40 nanometers are gradually formed. The particles are called primary particles of silica. They continue to move forward in the direction of the flame in the reaction furnace, and the particles collide and fuse together to form a non-porous, chain-like structure "aggregate". The silica "aggregate" continues to move forward and collide with the airflow in the pipeline, and then connects with each other to form a flocculent, fluffy ultrafine powder material, that is, the final form of fumed silica.

[0014] The fumed silica used in the present invention can be derived from commercially available raw materials, such as 200 (abbreviated as A200), with a specific surface area of ​​200 square meters / gram and a compacted density of about 50 grams / liter, can adhere to the surface of the scalp and hair. In addition to absorbing the oil secreted by the scalp, it can also increase the uprightness of the hair roots, increase the rigidity of the hair, and increase the friction between the hair strands, which can make the hair not flat but naturally fluffy and airy.

[0015] The shale oil sodium sulfonate of the present invention is obtained by drying and distilling the oil rock to obtain crude rock oil, and then obtaining volatile components by vacuum distillation, and then sulfonating to obtain shale oil sulfonate substances. The shale oil sodium sulfonate used in the present invention can be derived from commercially available raw materials, such as the shale oil sodium sulfonate of German Aikeyou Company. PALE, this raw material has high safety and good affinity with the skin. It has the effects of inhibiting sebum secretion, controlling the microbial environment of skin disorders, and soothing.

[0016] The capryloyl glycine of the present invention is obtained by reacting amino acid raw materials with acyl chloride to obtain a crude product, and then refined to obtain a raw material that can be used in cosmetics. The capryloyl glycine used in the present invention can be derived from commercially available raw materials, such as Puri-facteur (capryloyl glycine) of Dongguan Juwei New Material Technology Co., Ltd. This raw material is non-irritating to the skin, can inhibit the activity of 5α-reductase, strengthen the skin barrier, and has the effects of controlling oil secretion, soothing the scalp, etc., making the hair lighter, enhancing the fluffy feeling, and making the scalp healthier.

[0017] Through experimental exploration, it is found that the present invention uses fumed silica, sodium shale oil sulfonate and capryloyl glycine for compounding, and the three cooperate with each other to enable the prepared composition to play a synergistic role in fluffy and oil control, and when any one or two of the three components are missing, the fluffy and oil control effects of the composition are significantly reduced. In addition, when the inventor explored the dosage of each component, it was found that when the dosage ratio of fumed silica, sodium shale oil sulfonate and capryloyl glycine components exceeded the specified range of the present invention, the synergistic effect between the components was not obvious or even produced an antagonistic effect, which led to a decrease in the fluffy and oil control effects of the composition, indicating that the above three components have an ideal synergistic effect within the preferred range of the present invention.

[0018] Preferably, the fluffy oil-control composition comprises the following components in percentage by mass: 0.5-3% fumed silica, 0.1-2% sodium shale oil sulfonate, 0.05-0.2% capryloyl glycine, 1.5-6.5% moisturizer, 19-70% organic solvent, 0.8-1.6% preservative and the balance water.

[0019] Preferably, the fluffy oil-control composition comprises the following components in percentage by mass: 1.5% fumed silica, 1% sodium shale oil sulfonate, 0.1% capryloyl glycine, 5% moisturizer, 50% organic solvent, 1% preservative and the balance water.

[0020] Through experimental research, it was found that when the components of the present invention are combined in the optimal dosage ratio specified above, the obtained composition has the best fluffy and oil-control effects, achieving the effect of three-dimensional hair and matte oil control, and has the highest cost-effectiveness.

[0021] Preferably, the moisturizing agent includes polyethylene glycol-32 and polyethylene glycol-8.

[0022] The present invention selects polyethylene glycol-32 and polyethylene glycol-8 as moisturizers to be compounded with fumed silica, sodium shale oil sulfonate and capryloyl glycine to prepare a fluffy oil-controlling composition. The two moisturizer components cooperate with each other to effectively improve the hydration level of hair, making the hair softer and smoother, and to a certain extent improve the spreadability of the product, so that the composition can be spread on the hair more evenly, while avoiding excessive greasy feeling, which helps to keep the hair light and fluffy.

[0023] Preferably, the mass ratio of polyethylene glycol-32 to polyethylene glycol-8 is (0.5-5):(0.1-3).

[0024] Preferably, the mass ratio of polyethylene glycol-32 to polyethylene glycol-8 is (1-4):(0.5-2.5).

[0025] More preferably, the mass ratio of polyethylene glycol-32 to polyethylene glycol-8 is 3:2.

[0026] Through experiments and investigations, it was found that when polyethylene glycol-32 and polyethylene glycol-8 are compounded in the above-mentioned more preferred dosage range, the touch and lubricity of the composition can be effectively enhanced, and the moisture and gloss of the hair can be maintained, thereby bringing users a more comfortable and ideal use experience.

[0027] Preferably, the organic solvent comprises ethanol; and the preservative comprises p-hydroxyacetophenone and / or 1,2-hexanediol.

[0028] In a second aspect, the present invention provides a method for preparing the fluffy oil-control composition, comprising the following steps:

[0029] S1. Add the moisturizer into water, stir and homogenize until it becomes clear and transparent to obtain phase A;

[0030] S2, adding the preservative, capryloyl glycine and sodium shale oil sulfonate into an organic solvent, stirring and dissolving until clear and transparent, to obtain phase B;

[0031] S3, add phase B into phase A and stir evenly;

[0032] S4, adding fumed silica, stirring and homogenizing until uniform, to obtain the fluffy oil-control composition.

[0033] In a third aspect, the present invention provides use of the fluffy oil-control composition in preparing hair care products.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] (1) The present invention uses fumed silica, sodium shale oil sulfonate and capryloyl glycine for compounding. The three cooperate with each other to enable the prepared composition to exert a synergistic effect of fluffy and oil control, achieving the effect of three-dimensional hair and matte oil control;

[0036] (2) The present invention uses polyethylene glycol-32 and polyethylene glycol-8 as moisturizers to prepare a fluffy oil-controlling composition. The two moisturizer components cooperate with each other to effectively improve the hydration level of hair, making the hair softer and smoother, and to a certain extent improve the spreadability of the product, so that the composition can be applied more evenly on the hair, while avoiding excessive greasy feeling, which helps to keep the hair light and fluffy.

[0051] Comparative Examples 1-8

[0052] The present invention also provides the formulas of the fluffy oil control compositions of Comparative Examples 1-8, as shown in Table 2. The preparation methods of the fluffy oil control compositions provided in Comparative Examples 1-8 are similar to those of Examples 1-5, except that the formulas are different.

[0053] Table 2: Formula of the fluffy oil control composition described in Comparative Examples 1-8 (mass percentage %)

[0054]

[0055] Comparative Example 9

[0056] This comparative example provides a fluffy oil-control composition, which differs from Example 5 only in that conventional precipitated silica is used instead of fumed silica, and the remaining components, contents and preparation methods are the same.

[0057] Effect example

[0058] 1. Fluffy effect test:

[0059] The fluffy oil control compositions prepared in Examples 1-5 and Comparative Examples 1-9 were used as samples to test their fluffy effects. The specific method is as follows:

[0060] Apply hair oil to the hair bundle to simulate the oily state of hair, then evenly apply 1 mL of the sample on the hair bundle from top to bottom, grab the hair bundle evenly, wait for it to dry, and measure the volume of the hair bundle. The test is repeated five times in parallel. A Zeiss Kontron image analyzer connected to a Sony XC-77CE small camera (with a 60mm Nikon AF Micro-Nikkor lens) is used to measure the apparent changes of the hair bundle before and after using the sample. The image of the human model is captured by the camera, and the volume of the hair bundle is obtained after computer processing. Then the volume change rate of the hair bundle before and after the sample is calculated. The data is the average value of 5 evaluations. The specific results are shown in Table 3.

[0061] Volume change rate V(%) = (V 后 -V 前 ) / V 前 ×100%

[0062] Table 3

[0063]

[0064] From the results in Table 3, it can be seen that the fluffy oil-control compositions prepared in the embodiments of the present invention have a better effect in increasing the volume of hair, especially the composition prepared in Example 5 has a volume increase of 39.2%, and the fluffy effect of hair is significantly improved. Figure 1 This is a finished product picture of the fluffy oil-control composition prepared in Example 5. Figure 2 (AC) respectively show the states of the hair bundles when simulating the oily state of the hair and the states of the hair bundles after using the composition described in Example 5 for 1 hour and 3 hours. The pictures show that the composition described in Example 5 can effectively enhance the fluffiness and lightness of the hair bundles, and after using it for 3 hours, the hair bundles can still maintain a good fluffiness effect.

[0065] When comparative examples 1-3 lack fumed silica, sodium shale oil sulfonate or capryloyl glycine respectively, the hair fluffing effect of the composition is significantly reduced, especially when fumed silica is lacking; when any two of the above three components are simultaneously lacking in comparative examples 4-6, the increase in hair volume is not obvious, that is, the fluffing effect of the composition is significantly reduced compared with that in Example 5, indicating that when fumed silica, sodium shale oil sulfonate and capryloyl glycine are used as fluffy and oil-control active ingredients in the present invention, the three cooperate with each other to synergistically improve the fluffing effect of the composition; when the dosage ratio of fumed silica, sodium shale oil sulfonate and capryloyl glycine in comparative examples 7-8 exceeds the specified range of the present invention, the fluffing effect of the obtained composition on the hair bundle is also reduced compared with the embodiment. The above results show that fumed silica, sodium shale oil sulfonate and capryloyl glycine can better play a synergistic role within a specific dosage range, thereby significantly improving the fluffing effect of the composition.

[0066] 2. Oil control effect test:

[0067] The fluffy oil control compositions prepared in Examples 1-5 and Comparative Examples 1-9 were used as samples to test their oil control effects. The specific method is as follows:

[0068] The oil tester SebumeterSM815 is used to test the oil content of the skin. It is based on the principle of photometry. After a 0.1mm thick special matte tape absorbs the oil on the human skin, it will become a translucent tape, and its light transmittance will change. The more oil it absorbs, the greater the light transmittance will be, thus measuring the oil content of the skin.

[0069] 140 subjects with vigorous hair oil secretion, aged between 18 and 60 years old, were selected and randomly divided into 14 groups, 10 people in each group; the subjects did not wash their hair the day before the visit test, and sat quietly for 30 minutes in a test environment that met the standard on the test day. The test site was the forehead-5cm area on the top of the head, and the oil tester Sebumeter SM815 was used to test the skin oil content of the left and right foreheads of the subjects respectively; then 3mL of the sample was evenly applied to the hair of the test site from top to bottom, and the hair bundle was evenly grasped and left to dry. The oil content was measured again at 5h and 8h after the sample, and the average value of each group of test results was taken. Oil content change rate % = (oil content after using the sample-oil content before using the sample) / oil content before using the sample × 100%. The specific results are shown in Table 4.

[0070] After the test, the subjects evaluated the samples using a scoring system based on their experience. The evaluation items included fluffy effect and oil control effect. The scoring standard was 10 points, with 1 point being the worst and 10 points being the best. The evaluation results were the average scores of all subjects in each group as shown in Table 5. The higher the average score, the better the effect.

[0071] Table 4

[0072]

[0073] Table 5

[0074]

[0075] The results in Tables 4-5 also show that the composition prepared in the examples of the present invention has good fluffy and oil-control effects, thereby achieving the effects of three-dimensional hair and matte oil-control, effectively meeting the styling needs of consumers. However, in the comparative examples, due to the lack of the specific components or the dosage ratio exceeding the preferred range, the oil-control and fluffy effects of the composition are significantly reduced.

[0076] Finally, it should be noted that the above embodiments are intended to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
