Surfactants can also be used to clean plastic surfaces. Liu Yali] studied cleaning agents for plastic surfaces. The cleaning agent is composed of Las (sodium dodecylbenzene sulfonate), TX (octylphenol polyoxyethylene ether) and Ta (polyether non-ionic surfactant). It has good cleaning effect on ABS, PVC, PP and phenolic plastics.

There are cationic, anionic and non-ionic surfactants used as antistatic agents. Cationic antistatic agents include antistatic agent Sn, antistatic agent SP, etc., anionic antistatic agents include antistatic agent P, etc., and non-ionic antistatic agents include antistatic agent ECH, etc.

In the textile industry, many dyeing and finishing auxiliaries often use the complex of surfactants. However, the combination of surfactants produces synergistic effects and synergistic effects, and there are functions that a single surfactant does not have. Therefore, the compounding technology and synergistic effect of surfactants, as well as the relationship between the surface characteristics and application properties after compounding, have become an important research direction in the field of printing and dyeing auxiliaries, and also an extremely important research content to improve the quality of printing and dyeing.

The main purpose of the application of surfactant in leather soaking is to help soften the raw leather and restore the fresh skin state. Therefore, surfactants with good wetting and permeability should be selected, among which the effect of non-ionic surfactants is better. Most commonly used are carboxylate type anionic surfactants and polyoxyethylene type non-ionic surfactants, such as ramibang, Pingjia, etc.

Surfactants are also widely used in the production of finishing materials. When preparing pigment paste and polishing paste, sulfated oil should be added as dispersant and wetting agent; When preparing acrylic resin emulsion and nitrocellulose emulsion, adding a certain amount of surfactant can make emulsion stable, fine particles, uniform film formation and good gloss.

When the surfactant solution contains homologues or adds another surfactant or organic or inorganic electrolyte, the physicochemical or surface properties of the solution will change significantly and its application performance will be changed.

Surfactant is an important chemical material, which is called "industrial monosodium glutamate". Its application in leather industry has penetrated into all processes, which affects the quality and performance of finished leather to a great extent. In leather production, its functions of wetting, emulsification, dispersion, penetration and leveling are mainly used to promote or improve the physical and chemical effects of each leather making process, so as to shorten the production time, save chemical materials, improve the production efficiency and improve the quality of leather.

If the concentration of surfactant compound is slightly higher than its CMC, its levelness is better. This is because the solubilization of surfactants plays a decisive role in the levelness, while the cmc value of the complex has no obvious effect on the binding force between dyes and surfactants.

In the textile industry, many dyeing and finishing auxiliaries often use the compound of alkyl glycosides. However, the combination of surfactants produces synergistic effects and synergistic effects, and there are functions that a single surfactant does not have.

In recent years, with the continuous renewal of textile fiber varieties, new synthetic fiber materials such as composite fiber, special-shaped fiber and superfine fiber appear, which puts forward new requirements for printing and dyeing processing.

The synthesis of polymer surfactants has become one of the hot topics in the synthesis of surfactants in recent years. However, there is still a lot of basic work to be further studied in the continuous development of new products and the exploration of the relationship between their structure and performance.

The cationic surfactant obtained by quaternization of triethanolamine and natural oil can give good softness to the fabric. The amino ester obtained by the reaction of stearic acid, oleic acid, palmitic acid and triethanolamine is mixed with polyoxyethylene glycol laurate and methylated with sulfate to obtain fabric softener. In addition, a new softener amide ethyl imidazoline quaternary ammonium salt can replace dhtdmac. This kind of surfactant has low toxicity and is easy to degrade. Tubingalb, a biodegradable cationic active softener developed by chtr breitlich GmbH in Germany, has high directness and has no effect on fluorescent brightener. The treated fabric feels soft and bulky.

Surfactant is a kind of compound that can significantly reduce the surface tension of water at very low concentration. It can associate to form micelles after reaching a certain concentration, so it has a series of physical and chemical functions and corresponding practical applications, such as anti viscosity, emulsification or demulsification, foaming or defoaming after wetting, solubilization, dispersion, washing, anti-corrosion, anti-static and so on Fine chemical products with a wide range of uses.

Biosurfactants also have great development prospects. They are amphiphilic compounds with surface activity produced by the metabolism of biological systems. Compared with chemical synthetic surfactants, biosurfactants not only have high surface activity and strong emulsifying ability, but also have the advantages of non toxicity, non stimulation, fast and complete biodegradation, no environmental pollution and wide source of production raw materials, which are not possessed by general chemical synthetic surfactants. Therefore, there is a great potential demand in the market.

What are the main raw materials of alkyl glycosides? The main raw materials of alkyl glycosides are starch and its hydrolysates. Starch is a renewable natural resource with rich sources? Low cost. Alkyl glycosides are obtained by dehydration of starch hydrolysate glucose with aliphatic alcohols.

Alkyl polyglycoside APG 0814 has a softening effect on the skin and no irritation to the eyes. It is widely used in personal care and household detergents, such as shampoo, bath liquid, facial cleanser, hand sanitizer, etc.

Nonionic surfactants have excellent washing properties and strong decontamination ability even at low concentration; Less foam; Easy to be made into liquid detergent; It does not dissociate when dissolved in water and is not sensitive to hard water and electrolyte
