How much do you know about the wetting and solubilization effects of surfactants
Wetting effect, requirement: HLB: 7-9 Wetting is defined as the phenomenon where the gas adsorbed on a solid surface is displaced by a liquid. Substances that can enhance this displacement capacity are called wetting agents. Wetting is generally categorized into three types: contact wettin...Read more -
The development of green surfactant technology and products
Green surfactant technology and products have advanced rapidly, with some achieving internationally leading standards. The production of novel green surfactants using renewable resources such as oils and starches has become a major focus in recent research, development, and industrialization effo...Read more -
Application of Surfactants in Asphalt Pavement Construction
Surfactants have extensive applications in asphalt pavement construction, mainly including the following aspects: 1. As Warm Mix Additives (1) Mechanism of Action Warm mix additives are a type of surfactant (e.g., APTL-type warm mix additives) composed of lipophilic and hydrophilic groups ...Read more -
What are the principles behind the emulsifying and solubilizing actions of surfactants?
The steadily growing global trend of surfactants provides a favorable external environment for the development and expansion of the cosmetics industry, which in turn imposes increasingly higher demands on product structure, variety, performance, and technology. Therefore, it is imperative to syst...Read more -
What do you know about crude oil demulsifiers
The mechanism of crude oil demulsifiers is rooted in the phase-transfer–reverse-deformation principle. Upon addition of a demulsifier, a phase transition occurs: surfactants capable of generating an emulsion type opposite to that formed by the emulsifier (known as reverse-phase demulsifiers) come...Read more -
What are the factors that contribute to emulsion stability
Factors Governing the Stability of Emulsions In practical applications, the stability of an emulsion refers to the dispersed phase droplets’ ability to resist coalescence. Among the metrics for gauging emulsion stability, the rate of coalescence among dispersed droplets is paramount; it can be d...Read more -
What are the applications of nonionic surfactants
Nonionic surfactants are a class of surfactants that do not ionize in aqueous solutions, as their molecular structures lack charged groups. Compared to anionic surfactants, nonionic surfactants exhibit superior emulsifying, wetting, and cleaning capabilities, along with excellent hard water toler...Read more -
What are fatty amines, and what are their applications
Fatty amines refer to a broad category of organic amine compounds with carbon chain lengths ranging from C8 to C22. Like general amines, they are classified into four major types: primary amines, secondary amines, tertiary amines, and polyamines. The distinction among primary, secondary, and tert...Read more -
What are the classifications of fabric softeners?
A softening agent is a type of chemical substance that can alter the static and dynamic friction coefficients of fibers. When the static friction coefficient is modified, the tactile feel becomes smooth, allowing for easier movement across the fibers or fabric. When the dynamic friction coeffici...Read more -
What are the applications of flotation
Ore beneficiation is a production process that prepares raw materials for metal smelting and the chemical industry, and froth flotation has become the most important beneficiation method. Almost all mineral resources can be separated using flotation. Currently, flotation is widely applied in th...Read more -
What is flotation?
Flotation, also known as froth flotation or mineral flotation, is a beneficiation technique that separates valuable minerals from gangue minerals at the gas-liquid-solid interface by exploiting differences in the surface properties of various minerals in the ore. It is also referred to as “...Read more -
What are the functions of surfactants in cosmetics?
Surfactants are substances with a highly unique chemical structure and are widely used in the cosmetics industry. They serve as auxiliary ingredients in cosmetic formulations—though used in small quantities, they play a significant role. Surfactants are found in most products, including facial cl...Read more
