Title (EN) PH NEUTRAL DERUSTER COMPOSITION
(FR) COMPOSITION DE PRODUIT DÉROUILLANT DE PH NEUTRE
Abstract:
(EN) The present invention relates to a deruster composition of neutral pH which is designed to remove corroded metal from metal surfaces. The deruster composition can be used to remove rust or tarnish, and can also be referred to as a metal brightener. The deruster composition has a pH in the range of 5 to 8, where the composition comprises: water; at least one surfactant and at least one chelating agent; where at least one surfactant is an alkyl polyglycoside and at least one chelating agent is an aminopolycarboxylic acid. The ability to operate within a neutral pH range reduces damage to the metal during cleaning. In addition, hazards to operating personnel are minimised.
(FR) La présente invention concerne une composition de produit dérouillant de pH neutre, qui est conçue pour éliminer du métal corrodé de surfaces métalliques. La composition de produit dérouillant peut être utilisée pour enlever la rouille ou le ternissement et peut également être dénommée brillanteur de métal. La composition de produit dérouillant a un pH dans la plage de 5 à 8, la composition comprenant : de l'eau; au moins un tensioactif et au moins un agent chélatant, ledit au moins un tensioactif étant un polyglycoside d'alkyle et ledit au moins un agent chélatant étant un acide aminopolycarboxylique. La capacité à agir dans une plage de pH neutre réduit les dommages causés au métal pendant le nettoyage. En outre, les risques pour les utilisateurs sont réduits à un minimum.
