Abstract

A digestion assistant for lignocelluloses, containing one or more members selected from among nonionic surfactants represented by general formula (1): wherein R<1> is branched C4-C24 alkyl, m is such integers of 1 or above as to give an average of 4 to 20; A<1> is C3-C4 alkylene; and n is such integers of 0 or above as to give an average of 0 to 15, with the proviso that when the average of n is 1 to 5, the moiety in square brackets takes a random or block bonding mode.
