Description

Technical Field

[0001] The present invention relates to the technical field of skin care products, and in particular to an oil-controlling facial cleansing composition and a preparation method and application thereof. Background Art

[0002] Oily skin is a global problem, especially among people aged 15-39, and the root cause of oily skin is the excessive secretion of sebum. Sebum in healthy skin plays an important role in protecting the skin barrier, protecting the skin and hair from friction, regulating transepidermal water loss, maintaining the skin biofilm, and delivering antioxidants. In order to inhibit excessive secretion of sebum and restore the skin to a normal state, a large number of oil-control cosmetics have been studied in the prior art.

[0003] Facial cleansing milk is used to remove excess facial oil, dirt, cosmetic residues, etc., and is one of the essential products for daily skin care. Patent document CN110339110A records an oil-controlling facial cleanser, which achieves the purpose of oil control by adding white oak extract, licorice extract, angustifolia extract, and hydrolyzed red algae extract. However, its oil control effect still needs to be improved, and its oil content 4 hours after cleansing is less than 20% on average compared with the control group (data of Examples 1-5). Patent document CN114762671A records an oil-controlling facial cleanser, which achieves the purpose of oil control by adopting a reasonable combination of Indian bamboo stem extract, tea polyphenols, salvia miltiorrhiza flower / leaf / root extract, lemon balm leaf extract, and nettle extract. However, its oil content 4 hours after cleansing is less than 20% on average compared with the control group, and its oil control effect still needs to be improved. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide an oil-control cleansing composition and a preparation method and application thereof.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0006] In a first aspect, the present invention provides an oil-control cleansing composition, comprising the following components in parts by weight: 45-60 parts of a surfactant, 3-8 parts of a soapberry fruit extract, 1-5 parts of water / glycolipid, 1-3 parts of inulin, and 1-3 parts of water / butylene glycol / Cistanche deserticola extract.

[0007] As a preferred embodiment, the surfactant is selected from at least three of water / sodium cocoyl methyl taurate taurate / sodium chloride, disodium cocoamphodiacetate / water, water / sodium cocoyl glutamate, water / lauryl hydroxysulfobetaine / sodium chloride, and water / sodium lauryl glycol carboxylate.

[0008] As a preferred embodiment, the surfactant includes 20-30 parts of water / sodium cocoyl methyl taurate taurate / sodium chloride, 10-20 parts of disodium cocoyl amphodiacetate / water, and 10-15 parts of water / lauryl hydroxysulfobetaine / sodium chloride.

[0009] As a preferred embodiment, the composition comprises the following components in parts by weight: 24 parts of water / sodium cocoyl methyl taurate taurate / sodium chloride, 12 parts of disodium cocoylamphodiacetate / water, 10 parts of water / lauryl hydroxysulfobetaine / sodium chloride, 5 parts of soapberry fruit extract, 2 parts of water / glycolipid, 1.5 parts of inulin, and 2 parts of water / butylene glycol / Cistanche deserticola extract.

[0010] As a preferred embodiment, in the water / butylene glycol / Cistanche deserticola extract, the mass percentage of Cistanche deserticola extract is 3-5%.

[0011] Cistanche deserticola is a perennial parasitic plant of the Orobanchaceae family. It is mainly distributed in deserts and arid areas. It has extremely high medicinal value and is known as the "desert ginseng". It is a traditional precious Chinese medicinal material in my country. Cistanche deserticola contains rich Cistanche deserticola polysaccharides, phenylethanol glycosides, alkaloids, organic acids, etc. In addition, it also contains a large amount of mineral elements. Cistanche deserticola has the effects of nourishing the kidney and yang, moistening the intestines and relieving constipation; it is used to treat kidney yang deficiency, impotence and premature ejaculation due to insufficient essence and blood, uterine coldness and infertility, waist and knee pain, weakness, and constipation due to dry intestines. Modern pharmacological studies have shown that Cistanche deserticola polysaccharides can improve the body's immune function, promote DNA synthesis, enhance physical strength, improve intelligence, and have obvious anti-aging effects.

[0012] Glycolipid is a water-soluble lipid substance. It has a similar structure to the material that makes up the stratum corneum of the skin. It can quickly penetrate into the skin and combine with the water in the stratum corneum to form a network structure to lock in moisture.

[0013] Inulin is a natural fructan mixture composed of D-furanose molecules connected by β-(2,1) glycosidic bonds, and each inulin molecule end connected to a glucose residue by α-(1,2) glycosidic bonds, with a degree of polymerization (DP) of 2 to 60. Inulin is a soluble dietary fiber that can hardly be hydrolyzed and digested by gastric acid and can only be used by beneficial microorganisms in the colon, thereby improving the intestinal flora environment and further improving the intestinal environment. Therefore, it is mostly used as a prebiotic in the prior art.

[0014] In the experimental study of the present invention, it was unexpectedly found that after adding soapberry fruit extract, glycolipids, inulin and Cistanche deserticola extract to the surfactant, the cleansing composition formed can significantly reduce the skin oil content after 1-8 hours of use, and obtain a very good oil control effect.

[0096]

[0097] Efficacy verification:

[0098] 1. Oil control human efficacy test

[0099] According to the human test method for moisturizing and oil control efficacy of cleansing products in T / GDCA 008-2021, the oil control cleansing milk prepared in the above Examples 1-3 and Comparative Examples 1-6 was tested for oil control efficacy in humans, and the experimental data of each group were the average values ​​of multiple subjects (n≥20, the number of subjects in each experimental group was not exactly the same, but all were 20 or more). The specific method is:

[0100] Healthy Chinese male and female volunteers aged between 18 and 50 were selected and tested to have oily skin (the oil content on both sides of the forehead meets the following criteria: the oil secretion at about 0.5 cm above the left / right eyebrow is greater than 120 μg / cm for men) 2 , Male>100

[0101] μg / cm 2 ).

[0102] The subjects applied the test sample on one side of the forehead (sample group), and the other side of the forehead served as a blank control (blank group). The oil content of both sides of the forehead was tested using the instrument Sebumeter SM815 (CK, Germany) 1h, 4h, and 8h after washing.

[0103] The obtained oil content (unit: μg / cm 2 , which is the average value) and the test results of the reduction rate (%) of the fat content compared with the blank group are shown in Table 3. The calculation method of the reduction rate is:

[0104] Reduction rate = (blank group fat content - sample group fat content) / blank group fat content * 100%

[0105] Table 3

[0106]

[0107] From the results in Table 3, it can be seen that compared with Example 2, the oil reduction rates of Comparative Examples 1-6 at 1h, 4h, and 8h are significantly worse than those of Example 2, indicating that the surfactant, soapberry fruit extract, water / glycolipid, 1-3 parts of inulin, water / butylene glycol / Cistanche deserticola extract in the present invention have obvious synergistic effects after compounding, thereby improving the oil control effect. And from the results of Examples 1-2, it can be seen that the oil control effect achieved by using the component content ratio of Example 2 is the best, and its oil reduction rates at 1h, 4h, and 8h are as high as 44.01%, 47.70%, and 35.71% (as compared with the blank group) respectively. Figure 1 As shown, P value < 0.001, with a very significant difference).

[0108] 2. Evaluation of human efficacy for sensitive skin

[0109] According to the method in TCNMIA 0015-2020 Clinical Evaluation Standards for Soothing Efficacy Skin Care Products, the oil-control cleanser prepared in Example 2 was used as a test sample. The subjects used the test sample once in the morning and once in the evening. The sample was evaluated for its efficacy in sensitive skin by questionnaire survey and lactic acid stinging score at 7d, 14d, 21d, and 28d after using the product. The subjects were healthy Chinese male and female volunteers aged between 18 and 50 years old, and had sensitive skin (lactic acid stinging score ≥ 3 points).

[0110] The subjects were scored for lactic acid stinging pain at 0d and 28d. Figure 2 As shown, 28 days after the subjects used the test sample, the lactic acid stinging score decreased by 18.56% compared with 0 day, with a significant difference (0.001≤P value<0.01).

[0111] The 28 subjects conducted self-evaluation through a questionnaire 7d, 14d, 21d, and 28d after using the test samples. The skin reaction grade standards are shown in Table 4.

[0112] Table 4 Skin reaction grading standards

[0113] Grading Skin reactions 0 No response 1 Faint erythema 2 Erythema, infiltration, papules 3 Erythema, edema, papules, blisters 4 Erythema, edema, bullae

[0114] The questionnaire results showed that the skin reaction grade of 30 subjects after using the test sample for 7d, 14d, 21d, and 28d was 0, that is, no adverse reaction occurred. Therefore, the oil-control cleansing milk prepared by the present invention is suitable for sensitive skin.

[0115] The present invention has many specific application paths, and the above is only a preferred embodiment of the present invention. It should be pointed out that the above embodiments are only used to illustrate the present invention, and are not used to limit the protection scope of the present invention.
