Low-viscosity skin lotion and preparation method thereof

Abstract

The invention discloses low-viscosity skin-care emulsion and a preparation method thereof. The preparation method comprises the following steps: firstly, weighing the following components by weight percentage according to a formulation: 1.0 to 3.0 percent of main emulsifying agent, 1.0 to 3.0 percent of auxiliary emulsifying agent, 0.4 to 0.8 percent of stabilizing agent, 17.0 to 27.0 percent of emollient, 0.6 to 1.6 percent of preservative, and the balance being additive and deionized water; and then adding an oil-soluble component into an oil-phase pot, adding a water-soluble component into a water-phase pot, heating the pots respectively, extracting raw materials in the oil-phase pot and the water-phase pot into an emulsifying pot to homogenate the mixture, later cooling the mixture, adding residual components into the mixture, and discharging the skin-care emulsion. The viscosity of the low-viscosity skin-care emulsion prepared by the method is between 1,500 mpa.s and 3,000 mpa.s, emulsion centrifugation does not cause oil-water separation phenomenon, the viscosity of the emulsion is affected by temperature little, and at the same time, the production method for the emulsion has the advantage of simple process and can produce the emulsion by using the prior producing technique and equipment.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a low-viscosity skin care emulsion and a method for manufacturing the low-viscosity skin care emulsion. Background technique [0002] With the deepening of reform and opening up, the rapid improvement of people's living standards, and the continuous expansion of the cosmetics market, consumers not only put forward higher quality requirements for skin care lotions, but also have increasingly stringent requirements for product packaging and aesthetics. At present, most high-grade skin care lotions on the market are low-viscosity lotions, and high-grade hard materials are used as packaging containers such as glass and metal. Because the stability of low-viscosity emulsion is difficult to control, and the technical requirements are higher than those of skin care honey, most high-end low-viscosity skin care lotion products on the market are often found in large multinational companies and joi...

AI Technical Summary

Problems solved by technology

[0004] (2): Micro-emulsion technology is used to manufacture low-viscosity emulsion, but because the manufacturing process is difficult to control, the equipment requires high pressure resistance, complex equipment, and high production costs, this emulsion manufacturing technology is difficult to be adopted by some small cosmetics companies

[0005] (3): Another method of making low-viscosity emulsion is to use solubilization technology, so that water-insoluble skin care oils and essences can be dissolved in water through solubilization technology. The disadvantage of this method of making emulsions is that only a small amount of oil and essence can be added. The product is not good for moisturizing and skin care, and the use of too much solubilizer is very irritating to the skin

Most of the low-viscosity emulsions on the market are controlled within a certain viscosity range, and the viscosity of the emulsion generally does not exceed 3000mpa.s. The reason is that when the viscosity of the skin care emulsion is too high, it will not pour out in a hard material container, making it impossible for consumers to use it. Of course, the viscosity is not as low as possible. When the viscosity of the emulsion is too low (less than 1500mpa.s), the fluidity of the emulsion is too good, and it is not convenient for consumers to use

In addition, the viscosity of the existing emulsion changes greatly due to the influence of temperature, which can easily cause the viscosity of the emulsion to suddenly increase in winter or in cold areas and cannot be poured out of the hard packaging
