Description

Technical Field

[0001] The invention relates to the field of daily chemicals, in particular to a transparent water-emitting cream and a preparation method thereof. Background Art

[0002] Water-emitting cream is a kind of cream that can produce water droplets by rubbing. After contacting the skin, the water-emitting cream will break due to the temperature of the skin and rubbing, and the water droplets originally wrapped in the water-emitting cream will be exposed, thus creating the seemingly magical "water-emitting" phenomenon. The principle of water-emitting cream is an unstable oil-in-water system. Generally, water-phase substances in water-emitting creams account for about 80%, and oil-phase substances account for about 10%.

[0003] A good water-absorbing cream should not make users feel greasy. It can be used in skin care products such as skin cream, BB cream, sunscreen, etc. Traditional water-absorbing creams only have ordinary moisturizing ability, but water-absorbing creams are so widely used in the field of skin care products that it is worth considering how to improve the performance of water-absorbing creams. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a transparent water-absorbing cream and a preparation method thereof, which solves the problem that the traditional water-absorbing cream has a single skin care performance.

[0005] To achieve the above objectives, the present invention is implemented through the following technical scheme: a transparent water-emitting cream and a preparation method thereof, comprising the following raw materials in parts by weight: 4-10 parts of glycerin, 1-5 parts of propylene glycol, 1-5 parts of butylene glycol, 1-5 parts of PEG400, 1-2 parts of aloe extract, 1-2 parts of plantain extract, 0.5-1 part of L-fucose, 2-4 parts of rose essential oil, 1-2 parts of vitamin E, 4-8 parts of dimethylsiloxane, 3-6 parts of jojoba oil, 1-3 parts of emulsifier, 0.5-1 part of inorganic salt, 0.1-1 part of preservative, and 80-150 parts of deionized water.

[0006] Preferably, the emulsifier is one of polyoxyethylene alkyl ether glycerol fatty acid ester and sorbitan fatty acid ester. The former is a polyoxyethylene type nonionic surfactant, and the latter is a polyol type nonionic surfactant. The former is more hydrophilic than the latter, and both effectively improve the stability of water-oil combination by reducing the interfacial energy between oil and water.

[0007] Preferably, the preservative includes a water-soluble preservative and an oil-soluble preservative, the water-soluble preservative is sodium benzoate, and the oil-soluble preservative is one or more of methylparaben, ethylparaben, propylparaben, and butylparaben.

[0008] Preferably, the method for preparing the transparent water-removing cream comprises the following steps:

[0009] S1: Aqueous phase preparation

[0010] Deionized water, propylene glycol, butylene glycol, PEG400, glycerin and inorganic salt are added into a water phase stirring pot, heated and stirred, the temperature is controlled at about 75°C, and the water phase liquid substance is obtained after being fully stirred;

[0011] S2: Oil phase preparation

[0012] Add rose essential oil, jojoba oil, dimethylsiloxane, oil-soluble preservatives and emulsifiers into an oil phase stirring pot, heat and stir until the temperature is consistent with that of the water phase liquid substance, and stir evenly to obtain the oil phase liquid substance;

[0013] S3: Mixing and stirring

[0014] Transfer the oil phase liquid to the emulsifier, add the water phase liquid into the emulsifier while stirring, and after stirring evenly, lower the temperature to 35-40°C;

[0015] S4: Adding active substances

[0016] After the temperature in the emulsifier drops to 35-40°C, add aloe vera extract, plantain extract, L-fucose, vitamin E and water-soluble preservatives into the emulsifier, continue stirring, and after stirring evenly, lower the temperature to room temperature to complete the preparation.

[0017] Preferably, the inorganic salt in step S1 is sodium chloride.

[0018] The present invention provides a transparent water-release cream and a preparation method thereof, which has the following beneficial effects:

[0019] The invention replaces the high-content chemical oil phase substances in the traditional water cream preparation process by adding rose essential oil and jojoba oil, two aromatic essential oils extracted from natural plants. The rose essential oil has antibacterial, bactericidal and sedative effects and is suitable for any sensitive, red, swollen and inflamed skin. The jojoba oil is also rich in vitamin D and protein and is a good moisturizing and hydrating oil, which can maintain skin moisture, prevent wrinkles and soften the skin. In addition, four natural active substances, namely, aloe extract, plantain extract, L-fucose and vitamin E, are added. The aloe extract can improve the moisturizing ability of the water cream. The plantain extract is a total flavonoid. Like vitamin E, L-fucose has good antioxidant effects. L-fucose is a relatively rare monosaccharide substance with good moisturizing and antioxidant effects. The first three substances are more common and their prices are much lower than L-fucose. Adding them to the water cream in a ratio of 3:1 makes the water cream much more cost-effective. Not only does it make the preparation process more in line with the concept of green and natural skin care, but it also improves the whitening and moisturizing ability of the water cream, and increases the antibacterial and anti-inflammatory ability of the water cream. When the user's skin condition is poor, such as acne, you can still continue to use it without worrying about the excessive content of chemicals in skin care products causing damage to the skin barrier.
