cellulose into long‐chain alkyl glycoside surfactants has been carried out following two different routes: (1) Direct transformation of cellulose to butyl‐, hexyl‐, octyl‐, decyl‐ and dodecyl‐α,β‐glycosides in an ionic liquid media and Amberlyst‐15Dry as catalysts, with mass yield of up to 82 %; and (2) two steps reaction with transformation of cellulose into methyl glucosides, with a procedure described

Succinylation of Non-ionic Surfactants: Physicochemical Characterization, Functional Properties, Biodegradability and Mathematical Modeling of the Polarity Tuning
physicochemical and functional properties of anionic surfactants thus obtained were studied and compared with their non‐succinylated counterparts. A correlation between these properties and the polarity changes induced by the addition of the hydrophilic succinic acid moiety was established. The biodegradability of the succinylated surfactants has also been investigated. Finally, through a desirability
