  • the invention also provides a process for rinsing glass or ceramic articles by contacting the articles with a rinse aid composition provided according to the invention.
  • surfactant is a term of art which is defined in "Surfactants", Europa Press, 3rd Edition as the contemporary name for surface active agents, the class of chemical products whose molecules are able to modify the properties of a liquid/gas or liquid/liquid interface by lowering the surface, or interfacial, tension with associated changes occurring in other properties such as wetting. Those skilled in the art are in a position to select suitable surfactants and surfactant combinations to attain the purposes of the invention.

Abstract

L'invention concerne une composition de nettoyage de surface dure, alcaline, aqueuse, contenant des tensioactifs. Cette composition est destinée à être utilisée dans le lavage d'articles en céramique, en matière plastique ou en verre et comprend un tensioactif éther-carboxylate ou un tensioactif éther-carboxylate en combinaison avec un tensioactif alkyle polyglycoside. L'utilisation de cette composition de nettoyage dans le lavage du verre permet d'obtenir une bonne rétention de la mousse pour les bières et d'éviter d'avoir recours à une composition séparée facilitant le rinçage ou de réduire son utilisation. Le tensioactif ou la combinaison de tensioactifs a des propriétés facilitant le rinçage.
