Title (EN) ACIDIC LIMESCALE REMOVAL COMPOSITIONS
(FR) COMPOSITIONS ACIDES ELIMINANT LE TARTRE
Abstract:
(EN) The present invention relates to liquid acidic thickened compositions having a viscosity of at least 10 m Pa s, when measured with a Carrimed rheometer at 5 N/m2 at 20 °C, and a pH below 4, said composition comprising a thickening system comprising a zwitterionic surfactant and an anionic surfactant at a weight ratio of said zwitterionic surfactant to said anionic surfactant of at least 2:1, and from 0.1 % to 70 % by weight of the total composition of an acid. Said compositions deliver excellent limescale removal performance as well as outstanding greasy soap scum cleaning on hard-surfaces. The compositions are suitable for the cleaning of non-horizontal and horizontal surfaces.
(FR) Cette invention concerne des compositions acides, liquides et épaissies qui possèdent une viscosité d'au moins 10 mPa s, telle que mesurée à l'aide d'un rhéomètre Carrimed à 5 N/m2 et à une température de 20 °C, et un pH inférieur à 4. Cette composition contient un système épaississant qui comprend un tensioactif zwittérionique et un tensioactif anionique, ceci selon un rapport en poids du tensioactif zwittérionique par rapport au tensioactif anionique d'au moins 2:1. Cette composition comprend également de 0,1 à 70 % d'un acide par rapport à son poids total. Ces compositions offrent d'excellentes capacités d'élimination du tartre ainsi qu'une étonnante capacité de nettoyage de résidus de savon gras sur des surfaces dures. Ces compositions conviennent au nettoyage de surfaces horizontales ou non horizontales.
