CA 2248790

Aqueous, liquid hard surface detergent compositions having improved cleaning and good filming/streaking characteristics contain an amine oxide polymer at critical levels. Preferred formulas contain an amount of PVNO effective to provide an improvement in spotting/filming after at least three rewettings of the glass; hydrophobic solvent; detergent surfactant selected from the group consisting of anionic surfactants, amphoteric detergent surfactants including zwitterionic surfactants; and mixtures thereof; and the balance being an aqueous solvent system comprising water and, optionally, non-aqueous polar solvent.

Des compositions de détergents aqueuses liquides pour surfaces dures présentant des caractéristiques supérieures de nettoyage et ne formant pas de films/traînées contiennent un polymère d'oxyde aminique à des niveaux critiques. Les formules préférées contiennent une quantité de PVNO (poly(4-vinylpyridine n-oxyde)) efficace destinée à éliminer la formation de taches/films après au moins trois réhumidifications du verre, d'un solvant hydrophobe, d'un tensioactif détergent choisi dans le groupe constitué de tensioactifs anioniques, de tensioactifs de détergents amphotères y compris des tensioactifs zwitterioniques, et leurs mélanges, le solde étant constitué d'un système de solvants aqueux comprenant de l'eau et facultativement un solvant polaire non aqueux.
