Description

Technical Field

[0001] The present invention relates to the fields of "cosmetic preparation technology", "skin cleaning product field" and "chemical engineering and process field", and in particular to a mild three-layer makeup remover and a preparation method thereof. Background Art

[0002] In the field of cosmetic preparation technology, skin cleansing products are an important research direction. These products are mainly used to remove dirt, grease and cosmetic residues from the skin surface to keep the skin clean and healthy. Among them, makeup remover is a common skin cleansing product, which can effectively remove facial makeup and dirt to restore the skin to its natural state. In the field of chemical engineering and technology, the preparation of makeup remover usually involves the mixing and emulsification process of oil phase and water phase. Through appropriate formulation and process conditions, a makeup remover with good stability and cleaning effect can be obtained.

[0003] Existing makeup removers are mainly in the form of single-layer or double-layer liquids, and their main components include oil phase and water phase. The oil phase is mainly composed of vegetable oil, mineral oil, synthetic oil, etc., which is used to dissolve and disperse makeup and dirt. The water phase is mainly composed of water, moisturizers, preservatives, etc., which is used to dissolve the oil phase and provide moisturizing and cleaning effects. In addition, some makeup removers also add surfactants, thickeners and other ingredients to improve the stability and feel of the product.

[0004] However, existing makeup removers still have some problems in actual use. First, the cleaning power of most makeup removers is insufficient and they cannot completely remove makeup and dirt, especially for waterproof makeup and cosmetics that are worn for a long time. The use process is irritating, causing dry, tight or greasy skin, especially for people with sensitive skin or long-term cosmetic use, which may cause allergic reactions. In addition, during the storage and transportation process, existing makeup removers may also be affected by factors such as temperature and humidity, resulting in stratification, deterioration, etc., affecting the quality and use of the product.

[0005] In view of this, the present invention provides a mild three-layer makeup remover and a preparation method thereof. Summary of the invention

[0006] The object of the present invention is to provide a mild three-layer makeup remover and a preparation method thereof in view of the deficiencies of the prior art.

[0007] In order to solve the above technical problems, the following technical solutions are adopted: A mild three-layer makeup remover, comprising an upper oil phase, a middle water phase and a lower oil phase, wherein the upper oil phase accounts for 9-30%, the middle water phase accounts for 40-82%, and the lower oil phase accounts for 9-30%; The upper oil phase includes one or more of a variety of vegetable oils and / or synthetic oils; The middle aqueous phase comprises inorganic salts, glycerol, glucoside, panthenol, polyaminopropyl biguanide, water and water-soluble pigments; The lower oil phase is triethyl citrate.

[0008] A further improvement based on the technical solution is that the upper oil phase includes one or more of sunflower seed oil, moringa seed oil, golden jojoba seed oil, white meadowfoam seed oil, hydrogenated polyisobutene, and isomeric hexadecane.

[0009] A further improvement based on the technical solution is that the glucoside includes at least one of octyl glucoside, decyl glucoside and octyldecyl glucoside.

[0010] A further improvement based on the technical solution is that the inorganic salt includes at least one of sodium chloride, potassium chloride, sodium sulfate and potassium phosphate.

[0011] A further improvement based on the technical solution is that the water-soluble pigment is a mixed combination of one or more of lemon yellow, sunset yellow, amaranth, indigo, brilliant blue, roselle red, bilberry red, grape purple, and fruit green.

[0012] The present invention proposes another technical solution: a method for preparing a mild three-layer makeup remover, characterized in that the specific preparation steps are as follows: S1. Weigh each raw material of the upper oil phase and stir well; S2. Weigh each raw material of the middle aqueous phase and stir well; S3. After being inspected and qualified, the lower oil phase, the middle water phase and the upper oil phase are added into containers respectively, so as to obtain a three-layer makeup remover.

[0013] Further improvements based on the above technical solution include: Step S4, placing the container in an orbital shaker, setting the rotation speed to 200-300 rpm, and shaking for 5-10 minutes to fully emulsify the three phases; Step S5. After the shaking is completed, the container is allowed to stand for 0.5-1 hour to allow the three layers of makeup remover to separate into layers; Step S6. Observe the makeup remover after stratification to ensure that the interfaces between the phases are clear and each phase is clear, transparent or turbid.

[0014] The above technical solution has the following beneficial effects: 1. The three-layer makeup remover of the present invention is specially formulated so that it can be fully emulsified after being shaken and can be separated into layers after standing. The interfaces of the phases after separation are clear, which not only improves the stability of the makeup remover but also makes it more convenient to use.

[0015] 2. The makeup remover of the present invention has strong makeup removal ability, little residue, and can effectively remove facial makeup and dirt, especially for waterproof makeup and long-wear cosmetics, which is very attractive to modern people who pay attention to skin cleaning and maintenance.

[0016] 3. The makeup remover of the present invention is mild to the skin and does not cause irritation to the skin. After use, the skin does not feel noticeably tight or greasy, which is extremely safe and comfortable for people with sensitive skin or those who use cosmetics for a long time.

[0017] 4. The makeup remover of the present invention is not easily affected by factors such as temperature and humidity during storage and transportation, and is not prone to stratification, deterioration, and other problems, which greatly improves the quality and use effect of the product and reduces the risk of the product. In general, the three-layer makeup remover of the present invention has significant advantages over existing makeup removers in terms of cleaning effect, feel of use, safety, and stability.

[0018] 5. In addition to ensuring that it can remove makeup and grease on the face, it is gentle and non-irritating. It has a different appearance from other makeup removers. The upper oil phase does not contain oil-soluble pigments, but relies on the color of the selected plant oil, and finally appears light yellow. It can be fully emulsified after shaking, and can quickly stratify after standing. After multiple shaking and use, it can still maintain a clear oil-water interface. DETAILED DESCRIPTION
