Description

Technical Field

[0001] The invention belongs to the technical field of daily cosmetics, and particularly relates to a foam-type hair oil-control, wash-free, fluffy aerosol composition and a preparation method thereof. Background Art

[0002] As a typical aerosol product, hair volume spray quickly absorbs oil from the hair, leaving it fluffy and smooth without washing. However, as consumers increasingly prioritize product safety, spray-based products pose a risk of powder inhalation and the large amount of splashing during use can pollute and pose safety risks. Foam formulations perfectly address the safety risk of powder inhalation and prevent splashing during use. Furthermore, water-based formulas can be used in conjunction with various oil-control ingredients to provide long-lasting oil-control benefits. Chinese patent CN113975198A discloses a water-free shampoo mousse, which uses the fermentation product of Candida albicans / glucose / rapeseed methyl ester to be combined with trideceth-10 to make the hair dry and fluffy quickly and solve the problem of dandruff. At the same time, the shampoo mousse can keep the hair dry and fluffy within 6 hours after use. However, the patented technology mainly uses organic reagent ethanol as a solvent, resulting in poor stability of the adsorbent and extract in the ingredients, which makes the production process complicated and the irritation to the scalp is relatively high; Chinese patent CN113975198A discloses a water-free shampoo mousse, which uses the fermentation product of Candida albicans / glucose / rapeseed methyl ester to make the hair dry and fluffy quickly and solve the problem of dandruff. At the same time, the shampoo mousse can keep the hair dry and fluffy within 6 hours after use. However, the patented technology mainly uses organic reagent ethanol as a solvent, which results in poor stability of the adsorbent and extract in the ingredients, which makes the production process complicated and the scalp irritation is relatively high; Chinese patent CN11 4432182A discloses a makeup setting spray with an oil-control effect and a preparation method thereof. The film-forming agent in the spray is compounded with a skin feel regulator and a skin protectant. By inhibiting excessive secretion of sebum and combining the physical adsorption of sebum, it achieves an immediate and long-lasting oil-control effect and reduces oil secretion. However, the oil-control time of the spray is short and the stability is poor. Therefore, the development of an oil-control, long-lasting, and stable, wash-free fluffy aerosol will bring convenience to people's daily life, and at the same time effectively improve scalp health problems, control oil secretion, and alleviate scalp and hair problems such as hair loss. Summary of the Invention

[0003] In response to the problems existing in the prior art, the present invention proposes a foam-type hair oil-control, wash-free, fluffy aerosol composition and a preparation method thereof. The composition has the effect of making hair refreshing and fluffy, controls oil for a long time, is safe and reliable, and is suitable for a wide range of people.

[0004] In a first aspect, the present invention provides a foam-type hair oil-control, wash-free, fluffy aerosol composition, comprising water, an organic solvent, polysorbate 20, silica, aluminum starch octenylsuccinate, HDI / trimethylol hexyllactone crosspolymer, methyl methacrylate crosspolymer, polymethylsilsesquioxane, a composition having 5α-reductase activity inhibitory effect, a fragrance, and a propellant.

[0005] Furthermore, the foam-type hair oil-control, wash-free, fluffy aerosol composition comprises, by mass percentage, 30-70% water, 10-30% organic solvent, 0.5-3% polysorbate 20, 0.1-1% silica, 1-5% aluminum starch octenylsuccinate, 1-8% HDI / trimethylol hexyllactone crosspolymer, 1-5% methyl methacrylate crosspolymer, 1-5% polymethylsilsesquioxane, 2-8% composition having 5α-reductase activity inhibition, 0.1-1% fragrance, and 2-20% propellant.

[0006] Furthermore, the mass ratio of the HDI / trimethylol hexyl lactone cross-linked polymer, the methyl methacrylate cross-linked polymer, and the polymethylsilsesquioxane is 1:1-3:1-3.

[0007] Furthermore, the organic solvent is ethanol.

[0008] Furthermore, the propellant is propane and butane.

[0009] Furthermore, the composition having the ability to inhibit 5α-reductase activity comprises a Forsythia suspensa extract and a filtrate of a Leuconostoc / radish root fermentation product;

[0010] Furthermore, the mass ratio of the Forsythia suspensa extract and the filtrate of the Leuconostoc / radish root fermentation product is 1:4.

[0011] In a second aspect, the present invention provides a method for preparing a foam-type hair oil-control, wash-free, fluffy aerosol composition, comprising the following steps:

[0012] S1. In a reaction kettle, first mix water and a composition having 5α-reductase activity inhibition and stir evenly;

[0013] S2. In an appropriate amount of clean draw cylinder, mix ethanol, polysorbate 20, silica, aluminum starch octenylsuccinate, HDI / trimethylol hexyllactone crosspolymer, methyl methacrylate crosspolymer, polymethylsilsesquioxane and fragrance, and stir to disperse evenly;

[0014] S3, then add the mixed and dispersed liquid in the pull cylinder into the reactor, stir and mix evenly, and the basic liquid is completed;

[0015] S4. Fill the base liquid into the aerosol can, then place the aerosol valve, seal it, fill it with propane and butane, test it in a water bath, code the bottom of the can, install the nozzle, install the outer cover, and pack it into the box.

[0016] Furthermore, the preparation method of the foam-type hair oil-control, wash-free, fluffy aerosol composition is characterized in that the ingredients included in steps S1 to S4 are, by mass percentage, 30 to 70% water, 10 to 30% ethanol, 0.5 to 3% polysorbate-20, 0.1 to 1% silica, 1 to 5% aluminum starch octenylsuccinate, 1 to 8% HDI / trimethylol hexyllactone crosspolymer, 1 to 5% methyl methacrylate crosspolymer, 1 to 5% polymethylsilsesquioxane, 2 to 8% of a composition having 5α-reductase activity inhibitory effect, 0.1 to 1% fragrance, and 2 to 20% propane and butane.

[0017] Furthermore, the composition having the ability to inhibit 5α-reductase activity comprises a Forsythia suspensa extract and a filtrate of a Leuconostoc / radish root fermentation product;

[0018] Furthermore, the mass ratio of the Forsythia suspensa extract and the filtrate of the Leuconostoc / radish root fermentation product is 1:4.

[0019] In a third aspect, the present invention provides a composition having the activity of inhibiting 5α-reductase.

[0020] Furthermore, the composition capable of inhibiting 5α-reductase activity comprises a Forsythia suspensa extract and a filtrate of a Leuconostoc / radish root fermentation product.

[0021] Furthermore, the composition capable of inhibiting 5α-reductase activity may further include polysorbate 20, aluminum starch octenylsuccinate, HDI / trimethylol hexyllactone crosspolymer, methyl methacrylate crosspolymer, and polymethylsilsesquioxane.

[0022] Furthermore, the composition capable of inhibiting 5α-reductase activity may further include water, ethanol, silica, essence, propane and butane.

[0023] The core components of the foam-type hair oil-control, wash-free, fluffy aerosol composition prepared by the present invention include an adsorbent compounded from silica, aluminum starch octenylsuccinate, HDI / trimethylol hexyl lactone crosspolymer, methyl methacrylate crosspolymer, and polymethyl silsesquioxane, achieving an optimal adsorption rate and oil absorption value. When used, the composition can achieve a refreshing and fluffy hair after oil absorption without causing dullness and dryness due to excessive adsorption. At the same time, the HDI / trimethylol hexyl lactone crosspolymer, methyl methacrylate crosspolymer, and polymethyl silsesquioxane components contained therein have the characteristic of increased light transmittance after oil absorption, making them "transparent" after oil absorption, thereby achieving the advantage of not turning white without patting off, and providing a smooth feeling like freshly washed hair after use.

[0024] The hair oil-control, wash-free, fluffy aerosol composition of the present invention is prepared into a foam formulation. The powder in the composition can be evenly dispersed in a solvent, and after being sprayed, there is no splashing or other waste, and the composition can be completely applied to the hair. Moreover, the hair roots that are difficult to reach with spray-type products can be easily reached. Therefore, the composition of the present invention can achieve a comprehensive oil absorption effect without adding a large amount of powder.

[0025] The foam-type hair oil-control, wash-free, fluffy aerosol composition prepared by the present invention achieves its oil-control effect by, on the one hand, fully dispersing the powder and allowing it to remain at the hair roots and other parts of the body, allowing secreted oil to be immediately absorbed. On the other hand, by adding a Forsythia suspensa extract and a filtrate of a Leuconostoc / radish root fermentation product to form a compound oil-control component, the composition significantly inhibits 5α-reductase activity, thereby reducing DHT levels and effectively alleviating excessive oil secretion from sebaceous glands, further promoting the adsorption effect of the compound adsorbent.

[0026] The present invention uses water as the main solvent, and the components of the composition are highly compatible. The adsorbent can be stably dispersed in water, which can greatly simplify the production process and improve the stability of the product and the refreshing feeling during use. The adsorbent powder can quickly and instantly remove oily hair. At the same time, the addition of a composition that inhibits 5α-reductase activity can keep the hair and scalp fresh for a long time.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] (1) The foam-type hair oil-control, wash-free, fluffy aerosol composition of the present invention has a long-lasting oil-control effect. Compared with traditional rinse-off shampoos, the oil-control ingredients can work better and last longer, and are suitable for a wide range of people.

[0029] (2) The foam-type hair oil-control, wash-free, fluffy aerosol composition of the present invention can absorb the oil on the hair after use, making the hair refreshed and fluffy. Compared with common spray types, it has the advantages of less powder, no whitening of hair after use, and no risk of inhalation.

[0030] (3) The foam formulation of the present invention's oil-control, wash-free, fluffy hair aerosol composition uses a much lower amount of propellant than the spray formulation, and there will be no large amount of splashing of liquid and propellant during use, which can greatly reduce the safety risk of the product.

[0031] (4) The foam-type hair oil-control, wash-free, fluffy aerosol composition of the present invention uses water as the main solvent, which can greatly simplify the production process and improve the stability of the product and the refreshing feeling during use. DETAILED DESCRIPTION

[0049]

[0050] Test Example 1: Evaluation of the Cleansing and Fluffy Effect

[0051] Experimental product: foam-type hair oil-control, wash-free, fluffy aerosol composition sample of Example 1-3;

[0052] Number of subjects: 54, divided into 3 groups, with 9 male and 9 female volunteers in each group;

[0053] Experimental Method: Three groups of volunteers used the samples of Examples 1-3 daily. After daily use, the volunteers observed and analyzed the freshness, volume, and duration of the cleansing effect on their hair. Results were considered significant if the hair felt very fresh and fluffy, and the effect lasted for a long time; effective if the hair felt moderately fresh and fluffy, and the effect lasted for a moderate time; and ineffective if the effect was not significant. The average data were collected after 14 consecutive days of testing.

[0054] The observation data records are shown in Table 3-5:

[0055] Table 3 Test results of samples of Example 1

[0056]

[0057] The aerosol composition of the present invention was used on volunteers, and Example 2 was the best solution. It could make hair fresh and fluffy, have oil control effect, and keep the hair in good condition for a long time.

[0058] Test Example 2: Verification of Oil Control Effect

[0059] Purpose and Principle of the Study: 5α-reductase is a membrane protease that relies on reduced coenzyme II (NADPH). It is a key androgen-metabolizing enzyme in the skin, irreversibly converting testosterone (T) to dihydrotestosterone (DHT). DHT is the most active androgen and can induce excessive sebaceous gland secretion. Reducing DHT levels by inhibiting 5α-reductase activity can effectively alleviate excessive sebaceous gland secretion.

[0060] This is an in vitro method. Using a design, the 5α-reductase inhibition rate of a test sample is compared with that of a blank control group. If the inhibition rate of the test sample is superior to (higher than) that of the blank control group, and the statistical difference P value is less than 0.05, the test sample is considered to have a certain degree of oil-control efficacy.

[0061] The experimental method is as follows:

[0062] Experimental group: Example 2 foam-type hair oil-control, wash-free, fluffy aerosol composition sample;

[0063] Control group: water;

[0064] First, weigh the sample and pre-treat it. Add the reagent to the well plate and pre-react at 37°C for 30 minutes. After the pre-reaction is completed, add the enzyme reagent and continue to react at 37°C for 30 minutes. First, add the color developer to each well and develop the color at 37°C in the dark. Then add the stop solution. Measure the absorbance of each well in the upper test, record the data, and calculate the inhibition rate. The results are shown in Table 6.
