Composition of defoamer

Defoamers are widely used in industries such as latex cleaning, textile sizing, food fermentation, biomedicine, coatings, petrochemicals, papermaking, and industrial cleaning. So how do we understand the composition of defoamers? 

The components of defoamers include active ingredients, emulsifiers, and carriers. The following provides a detailed introduction to the functions of these components:

1. The active ingredients include silicone grease, polyether, fatty alcohol, mineral oil, vegetable oil, metal soap, etc. It has the functions of defoaming, anti foaming, and degassing, while reducing surface tension to improve the defoaming effect of defoamers. 

2. Representative emulsifiers include Tween series, Span series, additives (acrylic polymers), and polyether modified polydimethylsiloxane. It has the function of dispersing small particles of active ingredients, which are easy to disperse in water and have better defoaming and anti foaming effects. 

3. Carriers with water, insoluble or water-soluble solids (such as salts and solid organic compounds, fatty hydrocarbons) facilitate the combination of the carrier and the bubble system, facilitate decomposition into the bubble system, and combine the two. Its low surface tension helps to suppress bubbles and also reduces costs. 

Defoamers are used in the production of various industries to achieve excellent results in eliminating bubbles. However, people only know that defoamers have very good defoaming effects, but few people know that defoamers have an advantage. 

Defoamers have no side effects: It can be said that the absence of side effects is the main reason why organic silicon defoamers are widely used. In daily life, eating a piece of candy may also cause toothache. But defoamers have no side effects. Due to the use of a wide range of chemical elements in the production of defoamers, blending a variety of production materials together will result in a gentlest state. In this case, whether adding defoamers to food or other fields, there is no possibility of any harm to the human body.
