[0001] The invention relates to the field of A61K8 / 18, and in particular to a matte milk cap makeup setting spray and a preparation method thereof. Background Art

[0002] Traditional makeup setting sprays are difficult to achieve good waterproof and sweat-proof effects because they do not contain oily film-forming agents. Adding oily film-forming agents can significantly improve the waterproof and sweat-proof effects of makeup setting sprays, but oily film-forming agents, due to their oiliness, can cause problems such as oily glossiness, slow film formation, and compatibility with base makeup, resulting in mottled base makeup or weak makeup setting ability, thus giving consumers a bad experience of use. A Chinese patent (publication number CN 115517983 A) discloses a makeup setting spray and a preparation method thereof, which specifically uses one or more of acrylic acid (ester) / allyl methacrylate copolymer AMP salt, styrene / acrylic acid (ester) copolymer, polyvinyl pyrrolidone, polyester-5, and VP / VA copolymer. Although it can form a film with high adhesion on the skin, it cannot overcome the problem of oily makeup in actual use. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a matte milk cap setting spray, which effectively improves the problems of the setting spray with added oily film-forming agent, such as glossy makeup, slow film-forming speed, and weak setting ability.

[0004] On the one hand, the present invention provides a matte milk cap setting spray, which at least comprises the following components by mass percentage: 0%-5% of aqueous film-forming agent, 0.1%-5% of absorbent, 0.1%-5% of oily film-forming agent, 1%-10% of oily solvent, 0.1%-2% of emulsifier, 0%-1% of antioxidant, and water to supplement the balance.

[0005] As a preferred technical solution, the mass ratio of the oily film-forming agent, the oily solvent and the absorbent is 1:(1-5):(1-5), preferably 1:(1-2):(2-3), and most preferably 1:1.5:2.5.

[0122] Test cycle: 4H

[0123] Test instrument: Sebumeter SM815

[0124] Test principle: The oil content test adopts the world-recognized SEBUMETER method, which is based on the principle of photometer. A special matte tape with a thickness of 0.1mm absorbs the oil on human skin and becomes a translucent tape. Its light transmittance will change. The more oil it absorbs, the greater the light transmittance. In this way, the oil content in the skin can be measured.

[0125] Test environment: Test environment temperature: 21±1℃, relative humidity: 50±10%

[0126] Test method Oil control: The subjects do not use any cosmetics on the day and need to clean their faces before the test. Rest for 20 minutes in a laboratory with a temperature of 21±1℃ and a relative humidity of 50±10%.

[0127] (1) Clean the face with a facial cleanser (with good cleaning power), use sample 1 on the left forehead and sample 2 on the right forehead;

[0128] (2) Use a sebumeter to measure the oil content of the test area before, 2 hours, and 4 hours after use;

[0129] Analysis of test results: The lower the skin sebum value, the better the oil control effect.

[0130] Oil control effect (4h) Figure 5 , Figure 6The results show that: 4 hours after 10 subjects used the samples, the 4-hour oil control effect of Matte Milk Cap Setting Spray #1 (Example 2) was better than that of Matte Milk Cap Setting Spray #2 (Comparative Example 3); 4 hours after 10 subjects used the samples, the 4-hour oil control effect of Matte Milk Cap Setting Spray #4 (Example 1) was better than that of Matte Milk Cap Setting Spray #2 (Comparative Example 3).
