摘要:
A sorbent material is provided comprising a porous substrate, such as a nonwoven web, having a wetting chemistry distributed substantially throughout the substrate. The wetting chemistry can comprise (a) an aliphatic alcohol ethoxylate; (b) one or more of an alkyl sulfosuccinate, an alkyl sulfate and a sulfated fatty acid ester and, optionally, (c) a fatty acid ester ethoxylate. Various formulations are provided having low metal ion concentrations, anti-static properties and/or good absorption characteristics for a broad spectrum of liquids.
