Emulsifier is a kind of surfactant. The function of surfactant is to emulsify, and there are others. The main functions of surfactant are: stain removal, emulsification, solubilization, suspension, foaming and defoaming, There are many kinds of surfactants such as sterilization. According to the classification of use, there are emulsifiers, demulsifiers, antistatic agents, detergents, foam stabilizers, defoamers, and dispersants. These uses can be distinguished according to the magnitude of the HLB value. Wide range of surfactants, including emulsifiers. The HLB value of the surfactant is between 0-40, and the emulsifier is between 2-15, 2-8 is a water-in-oil emulsifier, and 9-15 is an oil-in-water emulsifier.

I will briefly introduce the difference between emulsifiers and surfactants. Then, is it harmful to eat emulsifiers? In terms of safety, emulsifiers have already passed strict toxicological safety evaluations and are very safe. They are not only used in my country, but also in International is also heavily used. However, the use of emulsifiers should also be appropriate, not too much use, excessive use of emulsifiers will also harm the function of the intestinal tract, therefore, everyone should learn more about food safety knowledge, and must promptly go to the relevant department to make food when in doubt Safety detector detection.

With the development of the economy and the improvement of people's living standards, the demand for new types of leather is increasing, and higher requirements are put forward for leather auxiliaries. It is urgent to develop special detergents, softening agents, and waterproof finishing agents for leather products. wait. Fluorosurfactants have high surface area, high heat resistance stability, high chemical inertness, are both hydrophobic and oil-repellent, and are non-toxic or slightly toxic. Silicon-containing surfactants contain both organic groups and silicon elements, high temperature resistance, weather aging resistance, non-toxic, non-corrosive, physiologically inert, and high surface activity. Therefore, it is urgent to develop special leather auxiliaries that contain fluorine and silicon and can endow leather with special properties.
