Abstract

The invention discloses a low-viscosity emulsion as well as a preparation method and application thereof. The low-viscosity emulsion is prepared from the following components in percentage by weight: 0.5 to 3.0 percent of an emulsifier, 0.01 to 0.2 percent of a polymer without an emulsifying function, 0.01 to 40 percent of grease and the balance of water, wherein the emulsifying agent is prepared from ceteareth-12 (ceteareth-12). The low-viscosity emulsion disclosed by the invention can be prepared by matching a single emulsifier with a low-content polymer without an emulsification function, a large amount of low-polarity to high-polarity grease can be emulsified, and the preparation method of the emulsion is simple in process, relatively low in production cost and suitable for large-scale production; the viscosity range of the emulsion is about 2500-7000 mPa.s, the emulsion is stable after being centrifuged for 30 min at the speed of 3000 rpm, the phenomena of layering, demulsification and the like do not occur after the emulsion is centrifuged for one month at the high temperature of 50 DEG C, and the viscosity is not greatly changed due to the influence of the temperature.

Description

technical field [0001] The invention relates to a low-viscosity emulsion and its preparation method and application. Background technique [0002] With 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 more and more stringent requirements for product packaging and aesthetics, making low-viscosity skin care products on the market. The demand for emulsions is increasing, and transparent or translucent visible materials (hard materials) are used as packaging containers, such as glass, metal and other packaging containers. However, according to the Stokes settlement formula ( Where: r is the particle radius, ρ 1 -ρ 2 is the density difference between the two phases, g is the acceleration of gravity, and η is the viscosity of the continuous phase). [0003] It can be seen that the stability of low-viscosity emulsions is more d...
