Description

Technical Field

[0001] The present invention relates to the technical field of makeup remover gels, in particular to a soothing and acne-clearing makeup remover gel and a preparation method thereof. Background Art

[0002] Makeup removal is an essential step in daily makeup application. While traditional makeup removers, such as cleansing oils and water, can remove facial makeup, they often have some shortcomings. Cleansing oils can clog pores and cause skin problems like acne due to incomplete cleansing, while cleansing water can cause excessive friction and damage the skin barrier.

[0003] For those with acne-prone skin, this product offers acne-fighting and anti-inflammatory benefits during makeup removal. Traditional makeup removers can exacerbate skin inflammation due to irritating ingredients or inadequate cleansing power. Paris polyphylla contains Paris polyphylla saponins VII and VI, which have anti-inflammatory and antibacterial properties, inhibiting Propionibacterium acnes and regulating anti-inflammatory factors. However, this product is rarely used in makeup removers.

[0004] Therefore, a soothing acne-clearing makeup remover gel and a preparation method thereof have become problems that need to be solved urgently. Summary of the Invention

[0005] The purpose of the present invention is to provide a soothing acne-clearing makeup remover gel and a preparation method thereof, which is targeted at people with acne-prone skin and can achieve acne-removing and anti-inflammatory effects during the makeup removal process, thereby solving the problem that traditional makeup remover products are unfriendly to acne-prone skin and easily aggravate inflammation, and providing a makeup remover product that has both cleansing and acne-removing and anti-inflammatory effects.

[0006] To achieve the above object, the present invention provides a technical solution: a method for preparing a makeup remover gel, comprising the following steps:

[0007] S1. Oil phase ratio and preparation

[0008] Portulaca oleracea extract, sweet almond oil, grape seed oil, and rosemary essential oil were heated in a 60°C water bath at a mass ratio of 6:3:1:1 and stirred at a speed of 800 r / min to obtain an oil phase;

[0009] S2. Preparation of Anti-acne and Anti-inflammatory Lotion

[0010] 15 g of Span85 was added to 11 mL of the oil phase, and the mixture was heated in a water bath at 60°C and stirred at 800 r / min for 1 min. 2 mL of the aqueous phase prepared from Paris polyphylla extract and 3 mL of CaCl2 solution were then added, and the mixture was stirred for 2 min under the same conditions to obtain a water-in-oil emulsion.

[0011] S3. Preparation of gel

[0012] Place 20 mL of sodium alginate solution in a 100 mL beaker and stir at 400 r / min for 2 minutes using a 5 cm long stirrer. Add 1 mL of the emulsion to the sodium alginate pool while stirring at 700 r / min. Add a destabilizer to the sodium alginate pool and continue stirring for 1 to 15 minutes to solidify the gel. Wash with double distilled water 2 to 3 times to remove excess sodium alginate, and store the prepared gel in a 0.24 g / L CaCl2 solution.

[0013] Furthermore, the preparation method of the Paris polyphylla extract is as follows: the Paris polyphylla dry rhizome is selected and crushed into 60-mesh particles, and the Paris polyphylla powder is mixed with deionized water in a mass ratio of 1:8; the temperature is set to 80°C in a constant temperature water bath, the extraction time is 2 hours, and extraction is performed twice; 0.1% complex enzyme is added to improve the extraction rate; while hot, it is initially filtered with a 200-mesh filter cloth, and then finely filtered with a 0.45 μm microporous filter membrane to obtain the Paris polyphylla extract.

[0014] Furthermore, the aqueous phase is prepared as follows: 1.7 g of Paris polyphylla extract and 340 g of hydrogel are stirred uniformly at room temperature to obtain an aqueous phase.

[0015] Furthermore, the preparation method of the CaCl2 solution is as follows: weigh 20 g of CaCl2·2H2O and dissolve it in 500 mL of double distilled water to obtain a CaCl2 solution for later use;

[0016] Furthermore, the sodium alginate solution was prepared as follows: 10 g of sodium alginate was weighed and dissolved in 1 L of double-distilled water, stirred at 500 rpm for 6 h, and placed in a 4° C. refrigerator for 24 h for standby use.

[0017] The present invention also provides a soothing acne-clearing makeup remover gel, which is prepared by the above-mentioned preparation method.

[0018] The advantages of the present invention over the prior art are: the present invention extracts Paris polyphylla components through specific temperature, time and complex enzyme-assisted extraction, and incorporates the purslane makeup remover gel matrix at low temperature during the aqueous phase preparation stage, thereby avoiding high temperature destruction of activity and achieving an effective combination of makeup removal and acne-removing and anti-inflammatory technologies.

[0019] The gel prepared by the method of the present invention can reduce the greasy feeling caused by makeup removal and is mainly composed of traditional Chinese herbal ingredients, which increases its safety. The gel prepared by the present invention is added with the medicinal herb Paris polyphylla, which has anti-inflammatory and antioxidant effects on the skin in addition to makeup removal, achieving optimized efficacy and improving user experience.
