Abstract
Mercerization wetting compositions comprising a compound of the formula ##STR1## where R.sub.1 is hydroxyl or --SO.sub.3 M, R.sub.2 is C.sub.4 -C.sub.18 alkyl, M is an alkali metal, n is 0 or 1, and m is from 2 to 6 are described. The mercerization wetting compositions of the invention are high-wetting and low-foaming. Moreover, the compounds are readily biodegradable.
Claims7
