Problems solved by technology

[0003] However, the general water-in-oil system on the market has high requirements on formula, equipment and process
From the process point of view, when raw materials are mixed, a certain heating temperature is required, and it often takes a long time, high-energy homogeneity, and high feeding speed requirements. It is necessary to control the feeding speed, frequency and weight of the water phase, which makes it difficult to produce on a large scale.
From the perspective of formula, the formula is difficult, and various stabilizers and co-emulsifiers need to be added, and the HLB value must be designed reasonably, and it is easy to break the emulsion and leak oil. At the same time, the product is also irritating and the skin feels when the paste is used. Greasy, thick, difficult to apply and other shortcomings

Embodiment 1

[0030] Embodiment 1: A kind of water-in-oil infant buttock protective milk and its preparation method

[0031]

[0032]

[0033] Step 1, completely dissolving the aqueous phase containing polyhydric alcohol;

[0034] Step 2. First use caprylic acid / capric acid triglyceride to homogeneously disperse the zinc oxide in the oil phase, then add other oil phase mixture, homogeneously disperse, then add emulsifier phase mixed phase, stir homogeneously for 10min, Mass speed is 2000r / min;

[0035] Step 3: Add the polyol-containing water phase into the mixed oil phase at one time, stir for 40 minutes, then add lavender essential oil, and continue stirring for 20 minutes to obtain the water-in-oil baby buttock protector.

[0036] The final product is a milky white emulsion. After being inspected at -8°C for one month, and after being cycled at -8°C to 45°C for one month, the product does not delaminate, does not leak water, does not leak oil, and has no obvious difference from the...

Embodiment 2

[0037] Embodiment 2: A kind of water-in-oil sunscreen and its preparation method

[0038]

[0039] Step 1. Disperse phenylbenzimidazole sulfonic acid in the polyol-containing water phase with deionized water, then add aminomethylpropanol to make it transparent, and then add other raw materials in the polyol-containing water phase to dissolve completely;

[0040] Step 2. Homogeneously disperse zinc oxide with caprylic / capric triglyceride and C12-15 alcohol benzoate to obtain a dispersed phase of zinc oxide for use; premix other raw materials in the oil phase except zinc oxide and Add the emulsifier phase to homogeneous stirring to dissolve completely, then add the dispersed zinc oxide dispersed phase, homogeneously stir evenly, and the homogenizing speed is 1500r / min;

[0041] Step 3. Add the polyol-containing water phase to the mixed oil phase, stir homogeneously for 30 minutes, then add essence, and stir homogeneously for 5-10 minutes to obtain water-in-oil sunscreen. The ...

Embodiment 3

[0043] Embodiment 3: A kind of water-in-oil body lotion and preparation method thereof

[0044]

[0045]

[0046] Step 1, completely dissolving the aqueous phase containing polyhydric alcohol;

[0047] Step 2. Stir and mix the oil phase and the emulsifier phase evenly;

[0048] Step 3: Add the polyol-containing water phase to the mixed oil phase at one time, stir for 40 minutes, then add the essence, and stir homogeneously (1500r / min) for 6 minutes to obtain the water-in-oil body lotion.

[0049] The final product is a milky white emulsion. It has been inspected at -8°C for one month, and after a cycle of -8°C to 45°C for one month, the product has no water or oil leakage, and there is no obvious difference from the constant temperature sample at 6°C; after three months of high-temperature stability inspection at 45°C There is no stratification phenomenon for one month; after 2000r / min, 30min centrifugation inspection also does not stratify.

Abstract

The invention discloses water-in-oil cream containing a natural source emulsifier and a preparation method thereof. The problems that an existing water-in-oil cream preparation process is complex, high in difficulty and difficult to produce on a large scale are solved. The method comprises the following steps: firstly, mixing a water phase and completely dissolving, then mixing an oil phase and an emulsifier and completely dissolving, then adding the water phase mixture into a mixed phase of the oil phase and the emulsifier, and homogenizing or stirring; and continuously stirring to obtain the water-in-oil cream containing the natural source emulsifier, wherein the emulsifying agent is a mixture of polyglycerol-3 polyricinoleate and polyglycerol-3 polyricinoleate. The water-in-oil cream prepared by adopting the method has the advantages of extremely simple process, low difficulty, simple components, good stability, light skin feeling, no greasy skin feeling, no heavy skin feeling and good use feeling.

Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a water-in-oil cream containing a natural source emulsifier and a preparation method thereof. Background technique [0002] Water-in-oil systems have been widely used in the cosmetic industry. Its characteristic is that it is easier to spread on the skin than the oil-in-water system, and it is easier to form a continuous protective film with sealing effect on the skin. Therefore, such products have good moisturizing, protective and repairing effects, and also have good water resistance and powder dispersibility, and are widely used in make-up, sunscreen and other products. [0003] However, the general water-in-oil system on the market has high requirements on formula, equipment and process. From the process point of view, when raw materials are mixed, a certain heating temperature is required, and it often takes a long time, high-energy homogeneity, and high feeding...
