Description

Technical Field

[0001] The invention belongs to the technical field of hair removal patch preparation, and specifically relates to a hair removal composition and application thereof in the preparation of a hair removal patch. Background Art

[0002] As more and more women pay more and more attention to their own image, especially in spring and summer, women's demand for hair removal products is getting higher and higher. Most of the popular hair removal products on the market are chemical type hair removal agents. Chemical hair removal agents are mainly divided into two types: inorganic hair removal agents and organic hair removal agents. Inorganic hair removal agents are mainly sulfides of alkali metals and alkaline earth metals, such as sodium sulfide, calcium sulfide, strontium sulfide, barium sulfide, etc.; organic hair removal agents are composed of thioglycolate, calcium thioglycolate, lithium, sodium, magnesium, strontium and other ingredients. The hair removal principle of hair removal agents is mainly to use the active ingredients in the hair removal agent to corrode the hair through chemical principles, so that the hair gradually becomes brittle and soft and then dissolves.

[0003] Most chemical depilatories on the market currently irritate the skin to varying degrees, and the depilatory effect lasts for a short time. New hair will grow out after about 3-7 days, and frequent use may cause skin redness, swelling, allergies, and thickening of hair. Therefore, developing a new depilatory product and applying it to depilatory patches has good prospects and effects. Summary of the invention

[0011] Preferably, the preparation process of the sweet almond extract in step S2 is: wash and dry the sweet almonds, send them to a grinder for crushing, the crushing temperature is 20-30°C, and the crushed particle size is 1-3mm; then squeeze them in a hydraulic press, control the feed temperature to 45-55°C, the bursting temperature to 50-60°C, the squeezing pressure to 25-35MPa, and the squeezing time to 20-30min, so as to obtain the sweet almond extract; the preparation process of the citrus fruit extract is: take the citrus fruit and crush it to 45-65 mesh, add water at a solid-liquid ratio of 1:10-15 to soak for 30-50min, heat and distill to 2-5h, and cool to obtain the citrus fruit extract.

[0012] Use of the depilatory composition prepared by any one of the above methods in preparing a depilatory patch.

[0013] Sweet almonds usually refer to the seeds in the fruit produced by the almond tree, which is a widely consumed nut. Sweet almonds can not only be eaten directly, but also used to make various foods, such as cakes, candies, beverages, etc. In addition, sweet almond oil is also widely used in cosmetics and personal care products.

[0024] Comparative Example 4 The difference between this comparative example and Example 1 is that no citrus fruit extract is added in step S2, and the other steps are the same.

[0025] Comparative Example 5 The difference between this comparative example and Example 1 is that no soft wax is added in step S3, and the other steps are the same.

[0026] Comparative Example 6 Commercially available depilatories were used for comparison.

[0027] The depilatory compositions obtained in the various embodiments and comparative examples were applied to the preparation of the depilatory patch of CN114568808A, and were used to replace beeswax to prepare the depilatory patch.

[0028] Healthy women with hair removal needs and sensitive skin were selected as subjects. Each subject was divided into groups and took the hair removal patch samples of each embodiment and comparative example and applied them to the places with body hair under the armpits or legs. The thickness of the application was preferably to completely cover the body hair. After waiting for 5 minutes, a paper towel was used to gently wipe against the direction of hair growth, and then rinsed with clean water. After the test, each subject scored the hair removal effect and mildness of the test sample used. The score was scored on a 10-point system, with 1 point as the worst and 10 points as the best. The duration was from the removal time to the growth of new hair. The results are shown in Table 1.

[0029] Table 1 Performance test results

[0030] It can be seen from the above performance test results that Examples 1-3 have good hair removal effects, mildness and effect retention time; in particular, the comprehensive performance of Example 3 is the most outstanding. However, since Comparative Examples 1-6 do not adopt the necessary technical solutions, their corresponding performance tests are significantly worse than those of the Examples. The above experimental results further prove the importance of the technical solutions defined in the present invention for its technical effects.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
