An ethoxylated alkyl phosphate (anionic surfactant) for the promotion of activities of proteases and its potential use in the enzymatic processing of wool

Pretreatments of wool fabrics with cationic, anionic or non-ionic surfactants were investigated to reduce surface tension and improve the wettability of the fibres in order to promote protease activity on the fibres in subsequent processes. Results showed that an ethoxylated alkyl phosphate (specific anionic surfactant) as well as the widely used non-ionic surfactant was compatible with proteases in the enzymatic treatment of wool. There is therefore a potential for using specific anionic surfactants to achieve efficient enzymatic scouring processes.
