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.
L'invention porte sur un matériau sorbant comprenant un susbtrat poreux, tel qu'une bande non tissée, dans la quasi totalité duquel est réparti un produit chimique mouillant. Ce produit chimique mouillant peut comprendre: (a) un éthoxylate d'alcool aliphatique, (b) un ou plusieurs alkyl sulfosuccinates, un sulfate d'alkyle et un ester d'acide gras sulfaté et, éventuellement, (c) un éthoxylate d'ester d'acide gras. L'invention porte également sur différentes formulations ayant de faibles concentrations d'ions métalliques, des propriétés antistatiques et/ou de bonnes caractéristiques d'absorption sur un large spectre de liquides.
