Cleavable surfactants are of interest for several reasons. Above all, the development of surfactants with weak bonds deliberately built into the structure is driven by the need for improved biodegradability of amphiphiles. The breakdown may be catalyzed by enzymes, and biodegradation would be the normal mechanism in sewage plants. Alternatively, the surfactant may degrade by chemical means, e.g., induced by acid, alkali, ultraviolet (UV) light, heat, or ozone. Acid- and alkali-labile… 
Development of Cleavable Surfactants
Abstract Cleavable surfactants are of great interest for numerous reasons. These are amphiphiles in which a weak linkage has been deliberately inserted, normally, but not always, between the
Cleavable Surfactants: A Comparison between Ester, Amide, and Carbonate as the Weak Bond
Cleavable surfactants, i.e., surfactants in which a weak bond has deliberately been inserted into the molecule, are of interest when remaining surface-active material at a surface can cause problems.
Nonionic ortho ester surfactants as cleavable emulsifiers.
There was a good correlation between increase of droplet size and degree of surfactant decomposition, and the change in emulsion stability, thechange in droplets size and the rate of surfACTant hydrolysis were studied at acidic pH at room temperature.
Synthesis of Cleavable Aryl Sulfonate Anionic Surfactants and a Study of their Surface Activity
A series of cleavable aryl sulfonate anionic surfactants were synthesized from cyanuric chloride, aliphatic amine and H-acid mono sodium salt. Their structures were identified by 1H NMR, Infrared
Gemini ester quat surfactants and their biological activity
It was found that the compounds with a long hydrocarbon chain showed higher activity, which proves that they incorporate more easily into the lipid bilayer of the erythrocyte membrane and affect its properties to a greater extent.
Hydrolysis driven surface activity of esterquat surfactants.
Interfacial behavior of two classes of esterquat surfactants, quaternary alkylammmoniumesters and amino acid betaine (trimethylglycine) esters of fatty acids were examined both experimentally and theoretically and it was found that surface activity of the mixture of surface active compounds resulting from the es terquat basic hydrolysis increases with time.
Carbamate-bearing surfactants: Micellization, solubilization, and biological activity
Abstract Herein novel cationic carbamate-bearing surfactants have been synthesized and characterized as effective building blocks for the development of polyfunctional nanosystems showing
Synthesis of cleavable silicone surfactant for water-repellent application
Polymeric silicone-based surfactants were prepared by the reaction of polyethylene glycol, maleic anhydride, polydimethylsiloxane, silicone oil, titanium isopropoxide, and sodium hydrogen sulfite.
Design of Stimuli-Responsive Dynamic Covalent Delivery Systems for Volatile Compounds (Part 2): Fragrance-Releasing Cleavable Surfactants in Functional Perfumery Applications.
The cleavable surfactant imine hydrolysed to release the covalently linked fragrance aldehyde and upon dilution showed a blooming effect for the hydrolytical fragrance release and a more balanced performance of a solubilized perfume by retaining the more volatile fragrances and boosting the evaporation of the less volatileFragrances.
Surfactant-free microemulsions with cleavable constituents
Abstract Surfactant-free microemulsions (SFME) comprising a cleavable hydrotrope/hydrophobic component were investigated regarding potential applications for green, microemulsion-mediated extraction
