Title (EN) METHOD OF DISHWASHING COMPRISING DETERGENT COMPOSITIONS SUBSTANTIALLY FREE OF POLYCARBOXYLIC ACID POLYMERS
(FR) PROCÉDÉ DE LAVAGE DE LA VAISSELLE COMPRENANT DES COMPOSITIONS DÉTERGENTES SENSIBLEMENT EXEMPTES DE POLYMÈRES DE POLY(ACIDE CARBOXYLIQUE)
Abstract:
(EN) Methods of dishwashing to remove soils are disclosed, including a first detergent wash step, wherein the detergent is substantially-free of water conditioning agents including polycarboxylic acid polymers and phosphonates, followed by a second step of rinsing under high temperature with a water conditioning agent, namely polycarboxylic acid polymers. The methods result in little to no precipitation forming on the treated ware due to the treating of the hard water before it contacts the alkalinity source which prevents precipitation and/or flocculation from occurring.
(FR) L'invention concerne des procédés de lavage de vaisselle pour éliminer les salissures, comprenant une première étape de lavage par un détergent, le détergent étant sensiblement exempt d'agents de conditionnement d'eau comprenant les polymères de poly(acide carboxylique) et les phosphonates, suivie d'une deuxième étape de rinçage à haute température avec un agent de conditionnement de l'eau, à savoir des polymères de poly(acide carboxylique). Les procédés entraînent peu à pas de formation de précipitation sur l'article traité en raison du traitement de l'eau dure avant qu'il entre en contact avec la source d'alcalinité, ce qui empêche la survenue d'une précipitation et/ou d'une floculation.
