In this study, a series of four surface-active compounds—N-alkyl betaine ethyl ester
chlorides, C n BetC2Cl—were synthesized and characterized in aqueous solutions. As with …

In aqueous solution aggregation behaviors and the microenvironment characteristics of the
micelle assemblies of five novel betaine surfactants, N-(3-alkoxy-2-hydroxypropyl)-N, N …

The term" betaine" is used to refer to the glycine betaine, but also its derivatives and an
organic compound carrying a quaternary nitrogen. Glycine betaine is an amphoteric small …

A series of surface‐active betaine esters of medium‐to long‐chain alcohols has been
synthesized. The hydrophobic parts used were decyl, dodecyl, tetradecyl, and oleyl chains …

Five novel zwitterionic surfactants with alkylbetaine structure incorporated by hydroxypropyl
group have been prepared. The structure and composition of these compounds of high …

Three types of undecanoic and 10-undecenoic acid-based surfactants were synthesized in
the present work: amphoteric amidobetaines, cationic amidobetaine chlorides and nonionic …

Cocamidopropyl betaine (CAPB) is widely used in personal care and industrial products,
due to its mildness, simple synthesis, valuable surface active properties and synergism with …

Recent studies have shown that the surfactants bearing an ultra‐long hydrophobic chain (>
C18) exhibit unique self‐assembly properties. However, their synthesis and surface …

Two new classes of gemini cationic surfactants—hexanediyl‐1, 6‐bis [(isopropylol)
alkylammonium] dibromide {in the abbreviation form: CnC6Cn [iPr‐OH] and CnC6Cn [iPr …

The unsaturated long-chain carboxybetaine and hydroxy sulfobetaine were synthesized by
the reaction of unsaturated octadecyl tertiary amine with sodium chloroacetate and 3-chloro …
