A molded body is produced from a molding material including a continuous phase and a dispersed phase by a three-dimensionalization step, a curing step, and a peeling step. The continuous phase of the molding material is a water phase containing a curable compound. In the three-dimensionalization step, the molding material is placed in a container. In the curing step, the curable compound is cured to form a cured product after the three-dimensionalization step. In the peeling step, the container and the cured product are separated after the curing step. In the dispersed phase removal step, the dispersed phase of the cured product is removed after the curing step.

A high internal phase emulsion stabilized by a low content of surfactant and its preparation method thereof are provided. An oil ethoxylate is added to a vegetable oil, and the resulting mixture is uniformly mixed under a low-speed stirring at room temperature. Water is added dropwise to the mixture of surfactant and vegetable oil under stirring, and a homogenization is performed on the obtained dispersed system by a high-shear dispersion emulsification homogenizer to obtain the high internal phase emulsion stabilized by oil ethoxylate. The preparation method requires a low content of surfactant, mild preparation conditions and simple operations. When the oil-phase volume fraction is 83 vol %, the minimum mass fraction of the oil ethoxylate to stabilize the high internal phase emulsion is 0.6 wt %, and the prepared oil-in-water type high internal phase emulsion has excellent stability and shows bright color, delicate odor, hydra feel and being easy to apply.

Provided are a pickering emulsion including: 0.01-20 wt % of particles having an average particle diameter of 10 nm-100 μm, and 0.01-20 wt % of a non-ionic water-soluble polymer, wherein the particles are positioned on an oil droplet surface, and a method of preparing the same.

Provided is a method for producing a homogeneous mixture and the homogeneous mixture using the same. A method for producing a homogeneous mixture comprises stirring two liquid components being immiscible each other; mixing and homogenizing the two liquid components as a first homogenizing stage in a high pressure; applying an ultrasonic wave to the first homogenized two components as a first ultrasonic stage; regulating a weight ratio of the homogeneous components; homogenizing the regulated homogeneous components as a second homogenizing stage in a high pressure; applying an ultrasonic wave to the second homogenized components as a second ultrasonic stage; and generating a homogeneous mixture without any layer separation.

Provided are a pickering emulsion including: 0.01-20 wt % of particles having an average particle diameter of 10 nm-100 m, and 0.01-20 wt % of a non-ionic water-soluble polymer, wherein the particles are positioned on an oil droplet surface, and a method of preparing the same.

This method comprises the following steps: (i) formation of drops of a first phase in a second phase substantially immiscible with the first phase; (ii) flow, in a flow line, of the drops; (iii) recovery of a dispersion comprising drops and second phase in a container; and (iv) injection of a solution into the flow line or at the outlet of the flow line, upstream of the container, the solution comprising at least one raw material which is not or is not very compatible with step (i) and/or step (ii).

The present invention falls within the petrochemical field, specifically in the field of developing standards for physical-chemical analyses. The present invention describes a process for preparing standard synthetic water-in-oil emulsions, which considers the application of the emulsion, the desired HLB, the type of surfactant to be used, and the characteristics of the aqueous and oil phases. The process results in water-in-oil emulsions with high stability. The emulsions obtained by the process of the present invention comprise a combination of surfactants, and present stability of up to 30 hours.
