Practical application of imidazoline:

Imidazoline, as an amphoteric surfactant, is suitable for the combination of anionic surfactants, which can reduce the irritation of products, and has been favored by users for its biodegradability, high purity, low toxicity and other mild properties, and has been further widely used in many fields.

The wetting rate of imidazoline as an amphoteric surfactant is twice faster than that of traditional surfactants. Imidazoline amphoteric surfactant can be used as an excellent solvent enhancer to enhance this property, and its excellent stability and transparency properties are more suitable for the formulation of higher solid products. The excellent performance of amphoteric surfactant is also that it has foaming stability, and the stabilizer suitable for foam has more excellent foaming property than the traditional product, and the foam quality generated by it is milky, smooth and rich.

1. Textile additives

Antistatic agent is an additive that is added to the complex or directly coated on the surface of the product to reduce the surface resistivity or volume resistivity of the plastic, moderately increase the conductivity, and prevent the accumulation of static electricity.

Antistatic agents can be divided into external antistatic agents and internal antistatic agents according to different methods of use. External antistatic agent is also known as coating agent, general water, alcohol and other appropriate solvents into a solution, through impregnation, spraying or brush coating and other methods to treat the surface of plastic products, and then dry to remove the solvent, to obtain products with antistatic agent coated surface. The effects of cationic surfactants were the best, followed by amphoteric, anionic and non-ionic antistatic agents.

Imidazoline, as an important cationic surface active product, is an excellent softening agent and antistatic agent in the formulation of textile additives and daily chemical products. Imidazoline amphoteric softener used in acrylic fibers has a good softening effect, and can also be used in fiber softener, cellophane anti-sticking agent and fiber rich oil agent.

Imidazoline has good permeability and cleaning power, dispersing ability to calcium soap, resistance to hard water and electrolyte, and can be used as an efficient cleaning agent for wool, woolen, silk and chemical fiber and other high-grade fibers after combining with other ionic surfactants.

Imidazoline has an affinity for fibers, and can be used in combination with cationic surfactants or alone as a lubricating, soft and antistatic treatment of various fibers.

Amphoterimidazoline derivatives used for fabric softness should generally have longer alkyl groups at the 2 positions than lubricants and detergents, so as to have a better affinity with the fiber. Imidazoline can also be used as a levelling agent in the dyeing of nylon, ethylene fiber and acetate, and has lubricating and antistatic properties. When combined with non-ionic surfactants, imidazoline can be used as a finishing agent in wool processing to soften, lubricated, improve feel and appearance.

Imidazoline amphoteric surfactant can be used in silk dyeing industry, using this softener can replace soap to refine real silk, to achieve no yellowing, and to obtain excellent results in the whiteness and grade of products. Using imidazoline softener to treat polyester spinning products can wash away the remaining dyes and pigments after viscose dyeing, reduce the friction coefficient and improve the spinnability of viscose top strips.

2. Leather industry

Imidazoline amphoteric surfactant is a fat and softener in the leather industry. It can replace sulfonated castor oil when combined with mineral oil, emulsifier and other softeners, which can greatly improve the luster and feel of suede leather, and can also process broken skin into soft skin, greatly simplifying the production process.

Leather is a complex of fiber protein, in order to obtain the corresponding softness, it must form a layer of lubricating oil between it and the fiber, so as to loosen the fiber and reduce the friction between the fibers. Amphoterimidazoline softener can be combined with other oils or diluted with water, and can improve the flexure and tensile properties of protein fibers by brushing, coating and softening.

Due to the robustness and irreversibility of this effect, it can prevent the recrystallization of the leather fiber in the drying process and the loss of oil caused by oxidation and volatilization of the leather or leather products in the placing process, resulting in the hardening and brittleness of the leather. It can keep the leather soft, plump, smooth, elastic and other effects for a long time.
