CA 2473037

The invention relates to the use of a composition for cleaning the outside of means of transportation. Said composition contains a) at least one tertiary amino oxide of formula R1R2R3NO, whereby R1 represents an alkylamidoalkyl, alkenylamidoalkyl, alkoxypropylamidoalkyl or alkenylamidoalkyl group having between 8 -18 C-atoms, R2 and R3 represent, independently from each other, low molecular alkyl radicals or hydroxyethyl radicals or hydroxypropyl radicals, b) at least one alkali metal salt of polyasparaginic acid having a molecular weight of between 5.000 g/mol - 50.000 g/mol, or a polyglutaminic acid having a molecular weight of between 5.000 g/mol - 50.000 g/mol, or a mixture of both substances, whereby the weight ratio of the components a):b) is between 10:1 and 3000:1.

L'invention concerne l'utilisation d'une composition servant au nettoyage extérieur de moyens de transport, contenant a) au moins un oxyde d'amine tertiaire de formule R¿1?R¿2?R¿3?NO, R¿1? désignant un groupe alkylamidoalkyle, alkénylamidoalkyle, alcoxypropylamidoalkyle ou alkényle-amidoalkyle ayant entre 8 et 18 atomes de C, R¿2? et R¿3? désignent, indépendamment l'un de l'autre, des restes alkyle de faible poids moléculaire ou des restes hydroxyéthyle ou hydroxypropyle, b) au moins un sel de métal alcalin d'acide polyaspartique de poids moléculaire compris entre 5.000 et 50.000 g/mole, ou d'acide polyglutaminique de poids moléculaire compris entre 5.000 et 50.000 g/mole, ou un mélange des deux substances, le rapport en poids des constituants a):b) étant compris entre 10:1 et 3.000:1.
