The main functions of surfactants in cosmetics include emulsification, dispersion, solubilization, foaming, cleaning, lubrication and softening. Surfactants are widely used in cosmetics and play an important role. The performance of the surfactant used in cosmetics is not only its single performance

In the oil removal process of pre-plating treatment, a large amount of foam produced by stirring or blowing will interfere with the cleaning effect, such as excessive foam rising will lead to the overflow of the working fluid, which not only causes waste of materials, increases the cleaning cost, bu

There are many determinants of the effect of negative-cationic surfactants on surface activity, and there is a synergistic effect when the structure of both sides is suitable. In the mixed system of negative-cationic surfactants, rod-like micelles are easily formed after mixing with each other due t

Levelling agent O-25 is also known as cetyl stearyl alcohol polyether, cetyl stearyl alcohol polyoxyethylene ether, C16-18 alcohol polyether, Pinga 0.Its performance and application are as follows:1, in the printing and dyeing industry, it is widely used as a levelling agent for direct dyes, VAT dye

Water dispersion system is commonly used to analyze the relationship between surfactant structure and dispersion. As a hydrophobic solid particle, it can adsorb the hydrophobic group of the surfactant, and if it is an anionic surfactant, the outward-facing hydrophilic genes have the same charge and

Fatty alcohols are alcohols with aliphatic groups of 8 to 22 carbon atomic chains. Fatty alcohols usually have an even number of carbon atoms and a hydroxyl group attached to the end of the carbon chain.One of the raw materials of surfactants used in detergents. The general formula is ROH. The R of

The broad concept of penetrant refers to a class of chemicals that can help the substance that needs to be permeated to penetrate the substance that needs to be permeated, and the industry generally uses surfactants (which can be anionic or non-ionic) or organic or inorganic solvents. Penetrants are

Polyethylene glycol PEG combined with pharmaceutical polymers, successfully developed can stay in the human blood for 5h nanospheres, in addition to containing drugs and medical tracers, but also to eliminate the rejection of immune cells, the smooth delivery of drugs to specific focal areas, but al

Food, clothing, housing and transportation, "clothing" is the basic needs of life.With the progress of society, dressing tends to pursue beautiful fashion. But beautiful to wear, tired to wash.In order to make clothes clean and easy to wash, detergents are constantly introduced: from soap, to laundr

Combustion is a REDOX reaction of luminescence, heat, flame and smoke, and the combustion of substances must meet three necessary conditions, that is, combustible, accelerant and fire source. Modern science has found that for some complex combustion, there is a fourth condition - the chain reaction.
