“…This could probably be explained by that hydroxyl groups and ring oxygens are working as acceptor sites of sodium ions. [13]. In the XIC of m/z 371, corresponding to C12 monoglycosides, two peaks with almost the same height are seen (Fig.…”

“…A considerable number of papers have dealt with analysis of APG using several different techniques: colorimetric determination [6], thin-layer chromatography [7], GC-MS [8], several HPLC methods [9,10], HPLC-MS [11][12][13], MALDI-TOF-MS [9] and both static and LC-NMR [12]. Reversed phase HPLC has been shown useful for the separation of alkyl glycosides with regard to alkyl chain length, DP and isomer composition (␣-vs. ␤-anomers, pyranosides vs. furanosides and (1-4) vs. (1-6) binding) [11][12][13].…”

“…Because of their good foaming properties and synergy with other surfactants, they have found application in dishwashing and laundry detergents and in other cleaning products (Zgola-Grzeskowiak et al, 2008). Also, their good skin tolerance makes them suitable for mild personal-care products (Kuhn and Neubert, 2004). They are prepared on the basis of renewable raw materials, namely (starch/sugar) and fatty alcohols (vegetable oils).…”

This study examines the primary and ultimate biodegradation of a non‐ionic surfactant, an alkylpolyglucoside, in ready biodegradability tests. The surfactant concentration was tested by the anthrone method, while the ultimate biodegradation (mineralization) was analyzed by the total organic carbon determinations. The influence of the concentration on the extent of primary and ultimate biodegradation and the kinetics of degradation also were determined. The primary and ultimate biodegradation was studied at different initial concentrations—15, 25, 50, 75, and 100 mg/L. The increasing concentration of test chemical from 15 to 100 mg/L resulted in a decrease in the relative maximum mineralization rate and longer estimated lag times by a factor of approximately 4.3. During the degradative process, two different stages were noted; these are better described with Quiroga and first‐order kinetic models, respectively. For the study of the influence of concentration, the parameters characteristic of the biodegradation profiles in the different biodegradation assays were evaluated.

Surfactants are a wide group of chemical compounds which have a large number of applications due to their solubility properties, detergency, endurance of water hardness, as well as emulsifying, dispersing, and wetting properties. Surfactants have a characteristic structure, with one or several hydrocarbon chains that form the lipophilic part of the molecule (or the hydrophobic part of the molecule) and one or several polar groups that form the hydrophilic part. These compounds, also called surface-active agents, can have different lengths and degrees of unsaturation in the hydrocarbon chains, as well as in the polar groups, giving rise to a wide variety of surfactants with different properties. Surfactants can be classified as ionic or non-ionic, depending on the nature of the hydrophilic group. The ionic surfactants are disassociated in water, forming ions. Notable within this group are organic acids, and their salts are anionic surfactants, while bases-amines of different degrees of replacement-and their salts are cationic surfactants. Some surfactants contain both acid and basic groups. These surfactants may be anionic or cationic and are therefore called amphoteric, or ampholytic. Surfactants constitute a group of substances in which the main characteristic is their accumulation in the interfaces, solid-liquid or liquid-gas, weakening the surface tension of the liquid. This property enables the formation of foams and the penetration of solids as a wetting agent, leading to wide and varied applications of these compounds [1]. These substances are widely used in household cleaning detergents, personal-care products, textiles, paints, polymers, pesticides, pharmaceuticals, mining, oil recovery, and the pulp and paper industries. Detergents and cosmetics involve the mayor use of these compounds. After use, residual surfactants and their degradation products are discharged to sewage-treatment plants or directly to surface waters. Several of these compounds are not biologically degradable

Characterization of Mixtures of Alkyl Polyglycosides (Plantacare) by Liquid Chromatography-Electrospray Ionization Quadrupole Time-of-Flight Mass Spectrometry

Abstract: The presented LC/ESI-QTOF-MS approach allows to analyze and characterize various APG products, such as Plantacare. The ability of this LC/ESI-QTOF-MS approach to analyze mixtures of APGs with other surfactants is demonstrated.
