Author Denis Sasseville 1 Affiliation 1 From the Division of Dermatology, Department of Medicine, McGill University Health Centre, Montreal, Quebec, Canada. The initial reaction conditions were first optimized at 2. The effects of structural variations on their physico-chemical and biological properties have been evaluated for a Alkyl glucosides and alkyl poly-glucosides are widely used as wetting agents, surfactants and emulsifiers in several industrial and cosmetic products. 5 Decyl glucoside is the most frequently used For low concentrations, the highest level of biodegradability was achieved by APG-R8-10DP1. The raw materials are typically starch and fat, and the See more Alkyl glucosides are surfactants synthesized through the condensation of long-chain fatty alcohols and glucose, extracted from vegetal, renewable sources. EC number. Search. Green circle - The chemical has been verified to be of low concern based on experimental and modeled data. Previously, the mutants of Dalbergia cochinchinensis Pierre dalcochinase showed potential in the synthesis of oligosaccharides and alkyl glucosides. At a given temperature the branched surfactants have slightly larger axial Resorcinol alkyl glucosides 7–12 were developed as novel tyrosinase inhibitors based on the structure of rhododendrin. 2-ethylhexyl glucoside, isooctyl glucoside, 2-propylheptyl glucoside, and isodecyl glucoside. fatty alcohol alcoxylates and alkyl glucosides) were supplemented to induce a low-foam profile that is A process for the preparation of higher alkyl monosaccharides and oligosaccharides which are surface active. The β-glucosidase-catalyzed synthesis of n-alkyl-β-d-glucosides through the condensation of glucose and n-alcohols with alkyl chain lengths of 6 to 12 was carried out in a biphasic system, where . For example, Decyl Glucoside with a degree of polymerization of 1. Development of GLUT1-targeting alkyl glucoside-modified dihydroartemisinin liposomes for cancer therapy Nanoscale. They are known as well-tolerated and are usually added to the primary surfactants in order to reduce the irritating potential of the main foaming agents. The substances have been examined by means of microscopy, crossed polarizers, 1H-NMR self-diffusion, 2H-NMR quadrupolar splittings, and small angle X AG 6206, Alkyl glucoside, Alkylglucosides, AG™ 6206 is a low foaming alkyl glucoside, non-ionic surfactant, based on a short chain fatty alcohol and glucose. Relevant identified uses of the substance or mixture and uses advised 39 Alkyl glycosides or alkyl polyglycosides (APGs) are non-ionic surfactants synthesized by 40 condensation of one or more carbohydrate units and a fatty alcohol; they are specifically named 41 alkyl glucosides if the carbohydrate is a glucose molecule. Commercial production of these surfactants is carried out in multiple steps through Long-chain alkyl glucosides, such as octyl and decyl β-d-glucopyranosides (OG and DG, respectively), are regarded as a new generation of biodegradable, non-ionic surfactants. Alkyl glucosides are surfactants synthesized through the condensation of long-chain fatty alcohols and glucose, extracted from vegetal, renewable sources and are used in various leave-on and rinse-off cosmetics and are considered of low irritancy and allergenicity. 6 mol of an alcohol (Exxal 10) of formula (II), wherein R is a Cg alkyl having a methyl substitution of about 2. 9 M 1-butanol. Enzymatic synthesis of alkyl glucosides, via reverse hydrolysis or Alkyl-glycosides and -polyglycosides are environment friendly, non-ionic surfactants with favourable properties like biodegradability and chemical stability. In this study, the N189F Long-chain alkyl glucosides, such as octyl and decyl β-D-glucopyranosides (OG and DG, respectively), are regarded as a new generation of biodegradable, non-ionic surfactants. The 3. The surfactants are made via different synthesis routes. IDENTIFICATION SAFETY DATA SHEET LAURYL GLUCOSIDE REVISION 5, DATE 01 JAN 2023 Form 21047, Revision 3, Page 2 of 10, 13-Jan-2025 02:26:06. 6 is a mixture of decyl monosaccharide Long-chain alkyl glucosides such as octyl β-d-glucopyranoside (OG) and decyl β-d-glucopyranoside (DG) are amphipathic non-ionic surfactants with wide-ranging applications, from cleaning products, food and cosmetic ingredients, drug carriers and solvents for membrane proteins (Wang et al. 2023 Mar;37(3):e334-e337. For example, the wide review of alkyl glucosides properties and applications was prepared by von Rybinski and Hill . It involves the direct glucosidation of higher alkanols, omitting the double alcohol interchange by careful adjustment of the reaction conditions primarily by limiting the rate of formation of the water of reaction and the rate of oligomerization. Their simple structure allows for rapid metabolism into glucose and the corresponding long-chain alcohol (which is subsequently converted to the corresponding fatty acid) — both of which are normal components of food. Some non-ionic surfactants are not only emulsifiers or solubilisers but foamy detergents. An allergy to one alkyl glucoside can cause cross-reactivity to other glucosides and therefore, if there is a high suspicion of contact allergy to a specific glucoside, this needs to be tested separately. Ecology and Toxicology of Alkyl Polyglycosides. Food & Nutrition Formulations We demonstrate how rather hydrophilic surfactants can be used for solubilizing simultaneously water and alkane. I. Contact dermatitis 80(5), 286-290. 3139 Allergic contact dermatitis to alkyl glucosides: Epidemiological situation in Spain J Eur Acad Dermatol Venereol . In addition to lending his industry expertise to Prospector, George consults with personal care and cosmetics suppliers. These were synthesized from 2,4-dibenzyloxybenzaldehyde using either the Wittig or the Horner-Wadsworth-Emmons reaction with Koenigs-Knorr glycosylation as key steps. 3 µM about 4 times more potent than that of kojic acid (3), a typical tyrosinase inhibitor 2. Patch testing with alkyl glucosides: Concomitant reactions are common but not ubiquitous(2019-05-01) One or more human case studies show possible immune or allergenic effects: Allergic contact dermatitis caused by alkyl glucosides(2014-03-01) Cleaning action and surfactant properties of a series of alkyl glucosides, having high detergent power, emulsifying capacity, and biodegradability and low foaming capacity, were studied. The present paper describes the preparation of molecular assemblies of industrially produced AOG, which is a mixture composed of different length of alkyl chains (C9-C12) with oligoglucoside moiety with a few (1 An extracellular β-glucosidase (β-glu x) from Sclerotinia sclerotiorum was used as catalyst for the synthesis of gluco-oligosaccharides (GOSs) and alkyl-glucosides. Human patch testing shows that incidence of alkyl glucoside-induced allergic dermatitis is relatively high. The Image J software was applied for semi-quantitative analysis of The alkyl glucosides named in this safety assessment are reported to function primarily as surfactants. Boozalis E, Patel S. (2012).
