Abstract: Compositions including a quaternary amine antiseptic component having a concentration of at least about 0.04% by weight; a poly carboxylic acid chelator having a concentration of at least about 0.05 M and/or an alphahydroxy acid buffer having a concentration of at least about 0.05 M; a (C8-C12) 1,2 alkane diol; and optionally water are provided. The compositions have a pH greater than or equal to 3.5 and less than 5.5 at 23° C. In certain embodiments, water is present in the composition at a greater weight percent than each of the quaternary amine antiseptic component; the polycarboxylic acid chelator, if present; the alphahydroxy acid buffer, if present; and the (C8-C12) 1,2-alkane diol. In certain embodiments, water is present in the composition at a greater weight percent than any other component.

Abstract: A method of making a nonwoven fiber web comprises: providing a melt-blown nonwoven fiber web comprising bonded primary fibers having an average fiber diameter of 2 to 100 microns, wherein the primary fibers comprise a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units; opening at least a portion of the melt-blown nonwoven fiber web to provide loose primary fibers; combining the loose primary fibers with secondary fibers; and forming a secondary nonwoven fiber web comprising the primary fibers and secondary fibers. A fiber web preparable according to the method and a multicomponent fiber including a first phase comprising a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units and a second phase comprising a non-biodegradable polymer.
