Sugarand oligo(ethylene oxide)-based surfactants behave quite differently despite of both being non-ionic surfactants. In a large number of studies the properties and behaviour of these two different kinds of surfactants were addressed. However, it was only recently that an extensive investigation has been carried out on the properties of respective mixtures focussing on mixtures of β-C12G2 (n-...

On admixture of non-ionic surfactant of the alkyl or dialkyl polyglycerol ether class and cholesterol with subsequent hydration in aqueous media, microscopic lamellar structures formed are known as niosomes or non-ionic surfactant vesicles. Method of preparation of niosome is same as of liposome technology i.e. hydration by aqueous phase of the lipid phase which may be either a pure surfactant ...

A systematic study of the physico-chemical properties of a series of new catanionic surfactants with ionic liquid properties is reported. Importantly, by avoiding environmentally unfriendly halide and imidazolium based moieties highly tunable surfactant ionic liquids have been prepared.

Cellulose nanofibrils (CNFs) present unique opportunities for rheology modification in complex fluids. Here we systematically consider the effect of ionic and non-ionic surfactants on the rheology of dilute CNF suspensions. Neat suspensions are transparent yield-stress fluids which display strong shear thinning and power-law dependence of modulus on concentration, G' ∼ c(2.1). Surfactant additi...

Twenty-two ionic and nonionic surface-active agents were applied to a standardized pea root meristem test system. Mitosis was inhibited by 16 surfactants at concentrations of 0.1% v/v. Two surfactants caused a slight depression in the mitotic index; the remaining four had no recognizable effect. Several compounds were irreversibly toxic at levels of 0.1% v/v. Five of the six known biodegradable...

In droplet-based microfluidics, non-ionic, high-molecular weight surfactants are required to stabilize droplet interfaces. One of the most common structures that imparts stability as well as biocompatibility to water-in-oil droplets is a triblock copolymer surfactant composed of perfluoropolyether (PFPE) and polyethylene glycol (PEG) blocks. However, the fast growing applications of microdrople...

Fundamental experimental data for moisture absorption of non-ionic polydisperse surfactants with differing ethylene oxide (EO) content and variable aliphatic portions were measured at relative humidities between 0 and 95% at 25 °C. Remarkable differences in moisture absorption were observed between surfactant classes but also within one series of surfactants differing in either EO content or th...
