Disclosed is a thermoplastic composition comprising an unreacted mixture of a poly(lactic acid) polymer, a polybutylene succinate polymer or a polybutylene succinate adipate polymer, or a mixture of such polymers; and a wetting agent. The thermoplastic composition exhibits substantial biodegradable properties yet is easily processed. The thermoplastic composition is useful in making multicomponent fibers or nonwoven structures that may be used in a disposable absorbent product intended for the absorption of fluids such as body fluids.
