Description

Technical Field

[0001] This application relates to the field of cosmetic technology, and more specifically, to a bicontinuous phase makeup remover oil and its preparation method. Background Technology

[0002] With the improvement of people's living standards, cosmetics have entered people's daily lives and have achieved unprecedented development. More and more female consumers are using makeup products to beautify their faces. Considering effects such as sweat and moisture resistance, commonly used makeup products include foundation, lipstick, mascara, eyeshadow, and blush. Most of these are oil-soluble or oil-dispersed, containing a large amount of oils, waxes, or silicone oils. These makeup products adhere strongly to the skin after application, making them difficult to remove completely with regular facial cleansers (such as soap-based or synthetic surfactant-based products). If gentle and thorough makeup removal is not performed, residual makeup will accumulate on the skin, making it dull and lackluster. Dirt deposited on the surface can also clog pores, leading to rough, dull skin over time, and causing skin problems such as enlarged pores, blackheads, and closed comedones.

[0003] Makeup removal is the most crucial step in skincare, leading to a booming market for makeup removal products. Cleansing oils are among the most effective cleansing agents, designed based on the principle of "like dissolves like." The cleansing process involves first dissolving makeup and dirt with the oil, then emulsifying it with water before removal. However, current cleansing oils on the market often leave a greasy residue that is difficult to rinse off, failing to achieve thorough makeup removal. Furthermore, current cleansing oil products also suffer from drawbacks such as strong irritation, skin damage, and a lack of skincare benefits. Based on the above, this application provides a bicontinuous phase cleansing oil and its preparation method. Summary of the Invention

[0004] To address the problems of current cleansing oils, such as being greasy and difficult to clean after use, being highly irritating, damaging the skin, and lacking skincare benefits, this application provides a bicontinuous phase cleansing oil and its preparation method.

[0005] In a first aspect, this application provides a dual continuous phase cleansing oil, employing the following technical solution:

[0006] A dual-continuous-phase cleansing oil comprising a phase A component and a phase B component;

[0007] The A phase component includes: squalane, isopropyl palmitate, isopropyl myristate, and emulsifier I;

[0008] The B-phase components include: almond oil, coconut oil-caprylate / capric acid ester, dioctyl carbonate, olive oil, olive fermentation oil, grape seed oil, colorless jojoba oil, burdock seed oil, sea fennel callus culture filtrate, Rosa damascena flower oil, comfrey oil, α-bisabolol, antioxidants, and emulsifier II.

[0009] Preferably, the bicontinuous-phase cleansing oil comprises the following raw materials in weight percentages: squalane 10-30%, isopropyl palmitate 10-30%, isopropyl myristate 10-30%, emulsifier I 5-20%, almond oil 5-20%, cocoyl oleate / caprylate 5-20%, dioctyl carbonate 5-10%, olive oil 0.1-5%, olive fermented oil 0.1-5%, grapeseed oil 0.1-5%, colorless jojoba oil 0.1-5%, burdock seed oil 0.1-5%, sea fennel callus culture filtrate 0.1-5%, Rosa damascena flower oil 0.1-5%, comfrey oil 0.1-5%, α-bisabolol 0.1-0.5%, antioxidant 0.1-0.5%, and emulsifier II 6-20%.

[0010] By adopting the above technical solution, the formula of this application is scientific, the proportions are strict, the raw materials are safe and non-irritating, and it has good skin care and maintenance effects; the makeup remover oil made by mixing phase A and phase B can effectively dissolve various makeup dirt and remove makeup thoroughly.

[0011] Unlike traditional cleansing oils, the dual-continuous-phase cleansing oil of this application can spontaneously and rapidly penetrate makeup without external force. The penetration process continues until the system reaches dynamic equilibrium. The entire makeup removal process is divided into three stages: dual-continuous structure - W / O (or O / W) structure - dual-continuous structure. It can remove both oil-based film-forming makeup (such as lipstick, lip gloss, etc.) and water-based makeup (such as eyeliner, mascara, etc.).

[0012] The dual-phase cleansing oil of this application can hold an appropriate amount of water, can be used on dry or wet hands without affecting the product's effectiveness, and does not require excessive friction during contact with makeup, thus reducing skin irritation and making it gentler.

[0013] Preferably, the emulsifier I is polyglycerol-10 dioleate.

[0014] By adopting the above technical solution and selecting hydrophilic polyglycerol-10 dioleate as an emulsifier, which interacts with the oil components in the formula, the resulting makeup remover is easy to wash off with water and is refreshing and non-greasy.

[0015] Preferably, the almond oil is sweet almond oil.

[0016] By adopting the above technical solution, the B phase component uses mild, gentle, lubricating, and non-greasy sweet almond oil as the base oil. The resulting cleansing oil has the effects of nourishing and moisturizing, soothing and anti-allergy, and can restore the skin to smooth and soft after use.

[0017] Preferably, the olive oil is olive fruit oil.

[0018] Preferably, the olive fermented oil is a compound of Candida albicans / glucose / methyl rapeseed oil fermentation product and olive fruit oil; the mass ratio of Candida albicans / glucose / methyl rapeseed oil fermentation product to olive fruit oil is 4:1.

[0019] By adopting the above technical solution, olive pomace oil has a moisturizing effect, and the fermentation product of Candida albicans / glucose / rapeseed oil methyl ester is rich in a variety of proteins and vitamins, and has the effects of oil control, anti-seborrheic, antibacterial and cleansing. When the two are used together, the resulting makeup remover oil has better moisturizing properties and stronger cleansing ability.

[0020] Preferably, the comfrey oil is a compound of flaxseed oil, comfrey root extract, and tocopherol; the mass ratio of flaxseed oil, comfrey root extract, and tocopherol is 5:4:1.

[0021] By adopting the above technical solutions, flaxseed oil has anti-aging and beautifying effects, comfrey extract has anti-inflammatory and antibacterial effects, and tocopherol has anti-aging and lipid metabolism-improving effects. The three are combined to make comfrey oil, which can be used in makeup remover formulas to effectively enhance the skin care effects of makeup remover.

[0022] Preferably, the antioxidant is a compound of tocopherol and sunflower seed oil; the mass ratio of tocopherol to sunflower seed oil is 1:1.

[0023] By adopting the above technical solutions, tocopherol can increase the antioxidant capacity of cells, maintain and promote reproductive function, and have anti-aging effects; sunflower seed oil can promote the regeneration and growth of human cells and protect skin health. When the two are used together, they can significantly improve the storage stability of makeup remover, remove free radicals in the body, and increase cell activity. The resulting makeup remover has the effects of reducing pigmentation, whitening, and delaying aging.

[0024] Preferably, the emulsifier II is polyglycerol-2-sesquioctanoate and octyldodecyl alcohol; the mass ratio of polyglycerol-2-sesquioctanoate and octyldodecyl alcohol is 1-10:5-10.

[0025] By adopting the above technical solution, and using nonionic emulsifiers polyglycerol-2 sesquioctanoate and octyl dodecanol as the B-phase component emulsifier, the self-emulsifying and penetrating properties of the prepared cleansing oil can be significantly improved. The resulting cleansing oil is safe and gentle, easy to rinse after use, and has a good skin conditioning effect.

[0026] Secondly, this application provides a method for preparing a bicontinuous phase cleansing oil, employing the following technical solution: A method for preparing a bicontinuous phase cleansing oil includes the following preparation steps:

[0027] S1. Weigh out the raw materials of phase A: squalane, isopropyl palmitate, isopropyl myristate, and emulsifier I; weigh out the raw materials of phase B: almond oil, cocoyl oleate / caprylate, dioctyl carbonate, olive oil, olive fermentation oil, grape seed oil, colorless jojoba oil, burdock seed oil, sea fennel callus culture filtrate, Rosa damascena flower oil, comfrey oil, α-bisabolol, antioxidant, and emulsifier II for later use.

[0028] S2. Add the raw materials of phase A, squalane, isopropyl palmitate, isopropyl myristate and emulsifier I, to an emulsifier, heat to dissolve, disperse, degas and cool to obtain phase A;

[0029] S3. Add the raw materials of phase B, namely almond oil, coconut oil-caprylate / capric acid ester, dioctyl carbonate, olive oil, olive fermented oil, grape seed oil, colorless jojoba oil, burdock seed oil, sea fennel callus culture filtrate, Rosa damascena flower oil, comfrey oil, α-bisabolol, antioxidant and emulsifier II, to phase A, disperse them fully, cool and package them to obtain the desired bicontinuous phase makeup remover oil.

[0030] Preferably, in step S2, the heating and dissolving temperature is 75-85℃, the degassing temperature is 55-65℃, and the cooling temperature is 40-50℃.

[0031] By employing the above technical solution, phase A is first prepared, then phase B is added and mixed. Based on the action of emulsifiers I and II, a bicontinuous phase cleansing oil is obtained. This preparation method is simple, the preparation conditions are mild, and it is suitable for industrial production. The resulting cleansing oil possesses both hydrophilic and lipophilic groups, allowing it to aggregate at the oil / water interface. It self-emulsifies upon contact with water, exhibiting rapid emulsification. When in contact with a significant amount of water, it gradually and spontaneously forms a nanoemulsion, minimizing droplet size to encapsulate skin impurities, achieving thorough cleansing and providing an ultra-refreshing feel. During the makeup removal process, this cleansing oil minimizes the surface tension of makeup, achieving a thorough makeup removal effect without repeated rubbing of the skin, and is gentle on the skin barrier.

[0032] In summary, this application has the following beneficial effects:

[0033] This product features a scientifically formulated and precisely proportioned recipe. The raw materials used are safe, non-irritating, and have excellent skincare benefits. It employs a mixture of phase A and phase B to create a bicontinuous phase makeup remover oil that can dissolve various makeup impurities and achieve rapid separation and removal. It has strong cleansing power and thoroughly removes makeup. It self-emulsifies upon contact with water, achieving a thorough makeup removal effect without repeated rubbing. It is gentle on the skin barrier, leaving the skin feeling refreshed and non-greasy after use. Long-term use can increase skin radiance and improve dryness and roughness. Detailed Implementation
