Explaining everything from the basics to applications of emulsion technology!

Emulsion Technology

What is an emulsion?

An emulsion is a system in which one liquid, such as water or oil, which is insoluble in the other, is dispersed in the form of very fine droplets (droplets) in the other liquid.

The emulsions developed and sold by Nippon Shokubai are liquids in which polymer particles, which are synthetic resins, are dispersed very finely and uniformly in water, with water as the continuous phase. polymer Also called an emulsion.


Nippon Shokubai specializes in emulsion technology, particularly in acrylic emulsion design technology. If you have any problems with various emulsions, please contact us here.

What are the uses of emulsion technology?

①Paints Inks & Coatings

Emulsion technology is used in architectural paints, industrial coatings, paper and textile coatings, and more, providing superior performance while reducing environmental impact.

(Product example)

ACRYSET™ paint resin (acrylic emulsion type)

② Adhesives

Emulsion technology is used as a pressure-sensitive adhesive for a wide range of applications, including paper, wood, and textiles.

(Product example)

ACRYSET™ adhesive resin

3. Cosmetics and personal care products

Emulsion technology is used in many everyday cosmetics and personal care products, including creams, lotions, shampoos, and conditioners.

What are the advantages of emulsion technology?

1. Environmental Consideration

The use of emulsion technology can reduce the use of organic solvents and lighten the burden on the environment. This technology can be used to reduce VOC emissions, an effort that the manufacturing industry has been stepping up in recent years.

② Improved stability

Emulsion technology allows for the stable mixing of liquids that do not normally mix, such as oil and water. If emulsion technology can be used to design a highly stable state, it can improve the product's long-term shelf life. In addition, technology has been developed to increase stability in water by incorporating functional materials that do not normally mix in water into acrylic emulsions.

3) Low viscosity even with high molecular weight

The polymer has a rounded structure in the inner layer (oil layer) of the emulsion, so viscosity does not depend on molecular weight.
