An improved polyethylenimine adduct for cellulosic products is prepared by condensing polyethylenimine with 0.05-0.4 mole of a C12-C22 fatty acid and thereafter capping the residual free amino groups by reaction in aqueous solution at 0*-50* C. with epichlorohydrin. The resulting product is an effective softener, sizing agent, and wet-strength additive for paper and other cellulosic products with superior color stability and increased resistance to yellowing. |
