Novel quaternary phosphonium salts, bearing one or more carbamate groups attached through nitrogen, are prepared by condensing a hydroxymethyl phosphonium salt having the formula [R.sub.4-n P(CH.sub.2 OH).sub.n ].sup.+ X.sup.- with an alkyl carbamate having the formula NH.sub.2 CO.sub.2 R'. The products, which have the general formula [R.sub.4-n P(CH.sub.2 NHCO.sub.2 R').sub.n ].sup.+ X.sup.-, are useful as finishing agents for imparting flame retardant or durable press properties to cotton fabrics.
