Definitions
- the invention relates to the field of daily cosmetics, and in particular to an oil-controlling and acne-removing shower gel and a preparation method thereof.
- the present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an oil-controlling acne-removing shower gel and a preparation method thereof.
- An oil-controlling and acne-removing shower gel comprises the following raw materials in percentage by weight: 10-18% of a surfactant, 0.3-1% of a thickener, 0.5-2% of sodium chloride, 0.05-0.2% of a pH regulator, 0.1-0.6% of azelaic acid, 0.1-0.5% of capryloyl glycine, 0.1-0.6% of a plant mite remover, 0.2-2% of a sophora flavescens extract, 0.01-0.1% of an epilobium fleischerii extract, 0.1-0.5% of a sugar isomer mixture, 0.1-0.5% of sodium ascorbyl phosphate, 0.5-1.5% of a tremella extract, 0.01-0.2% of a gentian extract, 0.6% of a preservative and the remainder of water.
- the surfactant is composed of sodium laureth sulfate, sodium methyl cocoyl taurate, cocamidopropyl betaine, sodium lauroamphoacetate, and cocamide methyl MEA.
- the plant acaricide is composed of thyme extract, rosemary water, 1,3-propylene glycol, dichlorobenzyl alcohol and phenoxyethanol.
- the thickener consists of tocopherol and PEG-120 methyl glucose dioleate.
- the sugar isomer mixture comprises sugar isomers, water, citric acid and sodium citrate.
- the pH adjuster is potassium hydroxide.
- the above-mentioned oil-controlling and acne-removing shower gel is prepared by a preparation method comprising the following steps:
- Azelaic acid also known as azelaic acid
- azelaic acid is currently mainly used to treat melanoma, chloasma, rosacea, hyperpigmentation, acne, etc.
- Mechanism of action of azelaic acid inhibiting skin oil secretion.
- Androgen especially dihydrotestosterone, induces the activity of sebaceous glands, which is one of the causes of acne.
- 5a-reductase in sebaceous glands can increase the bioconversion of testosterone into dihydrotestosterone, and azelaic acid can produce a competitive concentration inhibitory effect on this reductase, thereby reducing oil secretion of the skin; it has an anti-keratinization effect on normal skin and acne-infected skin, reduces the synthesis of filamentous keratin, prevents excessive keratinization of hair follicles, and unclogs pores.
- the epilobium yaker extract added to the formula also has a strong inhibitory effect on 5a-reductase.
- capryloyl glycine For acne/pimples caused by excessive growth of Propionibacterium acnes, capryloyl glycine has good skin affinity and is mild to the skin. At the same time, it can achieve a good inhibitory effect on Propionibacterium acnes and Staphylococcus aureus in a relatively short time (2min-5min), and has a significant effect on the prevention and treatment of acne and pimples. Therefore, this formula selects capryloyl glycine as the active ingredient to inhibit Propionibacterium acnes, which fully considers its characteristics of short action time and high action efficiency, and also considers its mildness to the skin.
- Sophora flavescens extract has a broad-spectrum antibacterial property, which can not only inhibit the biosynthesis of bacteria, but also affect the biological oxidation process of bacteria.
- the anti-inflammatory mechanism of Sophora flavescens extract is due to the stabilization of the red blood cell membrane, and it has a strong immunomodulatory effect. It can exert its anti-inflammatory effect through the changes in immune cells, cytokines and other inflammatory regulatory factors. It has a good effect on eczema and dermatitis, can relieve skin itching caused by inflammation, and accelerate the repair of acne skin.
- a plant-based mite remover is added to the formula.
- the main active ingredients of the mite remover are: thyme extract, rosemary, water and dichlorobenzyl alcohol. It has a strong killing and repelling effect on various types of mites. It can effectively prevent or relieve acne caused by mites.
- the compatibility mechanism of the acne-removing and oil-controlling ingredients in this formula covers various pathogenesis of acne/pimples, and can achieve more significant acne-removing and oil-controlling effects. At the same time, it also takes into account the mildness and safety of the overall formula, and is suitable for a wider range of people. It can not only be used for acne removal on acne-prone skin, but also for daily cleansing to prevent acne.
- FIG1 is a schematic diagram of the effect of use by subject 1;
- FIG2 is a schematic diagram of the effect of use by subject 2;
- the preparation method is as follows:
- the plant mite remover used in this application is produced and provided by Guangdong Dimei New Material Technology Co., Ltd.

Place about 0.020mL-0.025mL (liquid) of diluted test substance in the patch tester and apply it to the back of the subject with low-allergenic tape. Remove the test substance after 24 hours and observe the skin reaction at 0.5, 24 and 48 hours after removal. Record the results according to the skin reaction grading standard in the "Technical Specification for Safety of Cosmetics" (2015 edition).
- Test substance original cosmetic final product
- Subjects A total of 30 subjects (33 subjects were enrolled and 3 subjects dropped out), including 14 females and 16 males, aged 18 to 40 years old, with an average age of 29.50 ⁇ 6.31 years old, who met the subject inclusion criteria.
- Test environment temperature: 20°C ⁇ 22°C, humidity: 40% ⁇ 60%, and real-time dynamic monitoring.
- At least 30 subjects were recruited to use the test samples for 28 consecutive days.
- the improvement level of acne lesions was evaluated subjectively and by doctors.
- Antera 3D was used to collect and analyze the corresponding parameters of acne on the subjects' backs.
- the test probe SM815 was used to measure the oil content on the skin surface. The changes in various indicators before and after use were compared to determine the acne removal and oil control effects of the product.
- Acute inflammation or other skin diseases on the back such as eczema, lupus erythematosus, seborrheic dermatitis, psoriasis, severe epidermal exfoliation, etc.
- Any medications taken orally or topically in the past month that may affect skin condition or reaction such as antihistamines, antibiotics, insulin, anti-inflammatory drugs, vitamin A, steroid drugs, aspirin, thyroid drugs, etc.

- the subjects are prohibited from using acne-removing, oil-controlling, anti-inflammatory and antibacterial preparations; the subjects are prohibited from dripping, injecting, orally or taking other forms of preparations that affect acne-removing and oil-control tests; the subjects are mainly indoor activities and avoid long-term exposure to outdoor light.
- the subjects filled out a questionnaire in the human efficacy laboratory to evaluate the back condition and record the score.
- the 7-point scoring method was used to score the product in four aspects: skin feel, use effect, mildness and use satisfaction, and then make a judgment, and record it once for each follow-up visit.
- the dermatologists evaluated the acne lesions on the subjects' backs in the photos before using the product (D0) and 28 days after using the product (D28).

The average volume of acne in the test area was obtained through software analysis. The SM815 was used to detect the skin oil value at the test site. The measured value was used as the baseline value (D0). The product was then distributed and the use method was instructed. The subjects were required to return for a visit 28 days (D28) after using the product and undergo the same indicator test.
- test of the same subject should be completed by the same instrument and the same tester.
- the test site should be kept consistent between the two test time points.
- the 7-point scoring method (Table 5) was used to score the product's use effect, mildness, and use satisfaction in the questionnaire.
