Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, specifically relating to a sustained-release, low-irritant, and heat-generating composition, its preparation method, and its application. Background Technology

[0002] Currently, some shampoos contain ingredients such as peppermint and ginger, which can dilate scalp capillaries, promote scalp blood circulation, improve hair follicle nutrition supply, and enhance scalp metabolism through physical stimulation or the action of plant active substances, thereby preventing hair loss. For example, patent CN 109730956 B discloses a ginger shampoo, which is prepared from the following raw materials by weight percentage: ginger 20%-50%, sodium lauryl ether sulfate 10%-15%, polyquaternium-10 0.2%-0.5%, acrylate copolymer 2%-6%, polyquaternium-22 1%-4%, polyquaternium-47 1%-4%, cocamide DEA 1%-3%, cocamidopropyl betaine 6%-10%, lauryl ether-23 1%-2%, argan kernel oil 2%-3%, DMDM ​​hydantoin 0.3%-0.5%, fragrance 0.2%-1%, and pure water as the balance.

[0003] However, the stability and sustained-release properties of active heat-sensing components in plants such as ginger (e.g., gingerol) are relatively poor, resulting in poor storage stability and heat-generating stability when applied to products; in addition, the strong odor of plant components such as ginger and the sensitivity of some people to them limit their application. Summary of the Invention

[0004] In view of the shortcomings and deficiencies of the existing technology, the primary objective of the present invention is to provide a method for preparing a sustained-release, low-irritant, exothermic composition.

[0005] Another object of the present invention is to provide a sustained-release, low-irritant, exothermic composition prepared by the above method.

[0006] Another object of the present invention is to provide the use of the above-described sustained-release, low-irritant, heat-generating composition in shampoos.

[0007] The objective of this invention is achieved through the following technical solution:

[0008] A method for preparing a sustained-release, low-irritant, excitatory composition includes the following preparation steps:

[0009] (1) Add agar, sodium alginate, humectant, thickener, water-soluble preservative and water to an emulsifying pot, heat and stir to completely dissolve the materials, then add skin conditioning agent, vanillyl butyl ether and phenoxyethanol in sequence and stir evenly, keep warm for later use.

[0010] (2) The heat-insulating mixture from step (1) is cooled by dripping it into cooling oil at 0-5°C using a pelletizing machine to obtain spherical objects. The spherical objects are then transferred to a cleaning tank to clean the oil off the surface of the spherical objects, thus obtaining a slow-release, low-irritant, exothermic composition.

[0011] Furthermore, the moisturizer mentioned in step (1) includes at least one of sodium hyaluronate and glycerin.

[0012] Further, the thickener mentioned in step (1) includes at least one of hydroxyethyl cellulose and hydroxypropyl methyl cellulose.

[0013] Furthermore, the water-soluble preservative mentioned in step (1) is sodium benzoate.

[0014] Further, the skin conditioning agent mentioned in step (1) is at least one of pearl powder, synthetic fluorophlogopite, jojoba seed oil, keratin, and hydrolyzed keratin.

[0015] Furthermore, the heating and heat preservation temperature in step (1) is 85-90°C.

[0016] Furthermore, the cooling oil mentioned in step (2) is liquid paraffin, methyl silicone oil or vegetable oil.

[0017] Furthermore, the cleaning tank in step (2) uses an aqueous solution containing a surfactant.

[0018] In the above preparation method, the mass percentage of each material is as follows: agar 10-15%, sodium alginate 0.2-0.4%, humectant 1-3%, thickener 0.4-0.8%, water-soluble preservative 0.3-0.6%, skin conditioning agent 3-6%, vanillyl butyl ether 3-8%, phenoxyethanol 0.5-1%, and the balance is water.

[0019] More preferably, the mass percentage of each material is as follows: agar 10-15%, sodium alginate 0.2-0.4%, sodium hyaluronate 0.05-0.2%, glycerin 1.5-2.5%, hydroxyethyl cellulose 0.25-0.35%, hydroxypropyl methylcellulose 0.25-0.35%, sodium benzoate 0.4-0.5%, pearl powder 0.3-0.5%, synthetic fluorophlogopite 0.4-0.6%, jojoba seed oil 2-4%, keratin 0.1-0.3%, hydrolyzed keratin 0.4-0.6%, vanillyl butyl ether 4-6%, phenoxyethanol 0.5-1%, and the balance being water.

[0020] A sustained-release, low-irritant, exothermic composition was prepared by the method described above.

[0021] Application of the above-mentioned sustained-release, low-irritant, heat-generating composition in shampoos.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] (1) The sustained-release, low-irritation heating composition of the present invention uses vanillyl butyl ether as the heating component. Vanillyl butyl ether is an oil-soluble thermosensitive agent. After being applied topically to the skin, it can quickly produce a mild and lasting pyrogenic effect, including accelerating microcirculation, stimulating subcutaneous fat metabolism, and promoting capillary blood circulation. When applied to shampoo, it can generate a warming sensation, giving consumers the feeling of ginger; in anti-hair loss shampoo, it has the effect of promoting scalp blood flow, enhancing hair follicle metabolic activity, and helping to prevent hair loss.

[0024] (2) The heat sensation of vanillyl butyl ether lasts for several hours and can produce a strong heat sensation with very low dosage. When applied to shampoo, the heat sensation is relatively direct and strong, which can easily cause some irritation and is somewhat different from the sensation of real ginger. This invention uses a specific preparation process to encapsulate the ether, which can achieve a certain degree of slow release under the rubbing force during shampooing, reducing irritation and better simulating the heat sensation of ginger and improving the stability of the heat sensation. Detailed Implementation
