Cationic Surfactant - an overview | ScienceDirect Topics
A cationic surfactant is a type of chemical compound that is used as a template to synthesize silica mesophases in different reaction conditions. It is selected for the systematic investigation of the formation of mesoporous silica materials.
Surfactant - Wikipedia
The head of an ionic surfactant carries a net positive, or negative, charge. If the charge is negative, the surfactant is more specifically called anionic; if the charge is positive, it is called cationic. If a surfactant contains a head with two oppositely charged groups, it is termed zwitterionic, or amphoteric. Commonly encountered ...
Cationic surfactants: A review - ScienceDirect
2023年4月1日 · Cationic surfactants have gained significant interest since their introduction. Their properties and adsorption behavior onto different surfaces have driven the development of a plethora of surfactants with distinctive functionalities.
What are Cationic Surfactants? (with pictures) - AllTheScience
2024年5月21日 · Cationic surfactants are basically soaps or detergents, in which the hydrophilic, or water-loving, end contains a positively-charged ion, or cation. Typical examples are trimethylalkylammonium chlorides, and the chlorides or bromides of benzalkonium and alkylpyridinium ions.
Cationic Surfactant - an overview | ScienceDirect Topics
Cationic surfactants contain a hydrophilic positively charged group, for example, long-chain amines, acylated diamines, and polyamines, and their salts and quaternary ammonium salts such as cetyl trimethyl ammonium bromide (CTAB) and cetyl trimethyl ammonium chloride (CTAC).
Shampoo and Conditioners: What a Dermatologist Should Know?
Conditioner molecules contain cationic surfactant which gives a positive electric charge to the conditioner. The negative charge of the hair is attracted to the positively charged conditioner molecules, which results in conditioner getting deposited on the hair, especially on areas where there is degree of weathering.[ 1 , 42 , 43 ] This is ...
Cationic Surfactants | Encyclopedia MDPI
2023年3月24日 · Cationic surfactants are a type of surfactant that carry a positive charge on their hydrophilic (water-loving) head group. They are commonly used in a variety of industrial and personal care applications, including fabric softeners, hair conditioners, disinfectants, and more.
Surfactants - SpringerLink
Cationic Surfactants. The most common cationic surfactants are the quaternary ammonium compounds (Jungermana 1970; Rubingh and Holland 1991) with the general formula R′R″R″′R″″N + X −, where X − is usually chloride ion and R represents alkyl groups. These quaternaries are made by reacting an appropriate tertiary amine with an ...
Synthesis and characterization of cationic surfactants and their ...
2019年6月10日 · The synthesized cationic surfactants are found effective in increasing the solubility and bioavailability of drugs. By varying alkyl chain length, we can vary CMC so we can control retention time of drugs in body.
What is a Cationic Surfactant Definition, Examples, Features
Cationic surfactant is a type of surfactant with a positive charge on its hydrophilic end. A common example of cationic surfactant is alkyl ammonium chlorides.
