Definitions

  • the subject of the application is a cleaning agent for hard surfaces, in particular glass, which is applied by means of a spray dispenser in the form of a foam on the surface to be cleaned and fatty alcohol sulfate and / or fatty acid sarcosinate and isopropanol and butyl glycol.
  • the foam produced during spraying sticks well even on vertical surfaces, but decays quickly when wiping with a quiet crackling and leaves almost no residue on the cleaned surface; In particular, no streaking or streaking is observed.
  • the cleaning agent When cleaning hard surfaces, it is always desirable that the cleaning agent is in turn completely removed after successful removal of the soiling and dries residue-free if possible. In particular, on glass surfaces otherwise remain unsightly streaks and streaks, which can only be removed by increased workload. Furthermore, it is desirable, especially for vertical surfaces, such as windows or mirrors, that the cleaning agent does not run off immediately after application, but adheres to the contaminants for a certain time to allow a better release of the dirt. This can be effected, for example, by applying the detergent in the form of a foam. However, this foam should quickly disintegrate during subsequent wiping with a cloth, sponge, leather or other suitable substrate to ensure the desired residue-free cleaning.
  • the object of the present invention was therefore to provide an aqueous cleaner for hard surfaces with good cleaning performance, which on the one hand forms a stable and well-adhering foam, on the other hand, quickly decays during wiping and leaves as few residues when removing.
  • an aqueous cleaner for hard surfaces, in particular glass which is applied by means of a spray dispenser in the form of a foam on the surface to be cleaned and fatty alcohol sulfate and / or fatty acid sarcosinate and isopropanol and butyl glycol, has a particularly good cleaning performance.
  • the resulting foam adheres particularly well to the surface to be cleaned, so that the dirt wets and dissolves for a longer time, on the other hand, the foam decomposes but quickly when wiping and can be removed almost residue and streaks. At the same time, a crackling sound is heard when the foam breaks down greater degree of contamination is increased, so that the user can simultaneously experience the effect of the agent sensually.
  • the subject of this invention is therefore an aqueous hard surface cleaner which is applied by means of a spray dispenser in the form of a foam on the surface to be cleaned and containing a fatty alcohol sulfate and / or fatty acid sarcosinate and isopropanol and butyl glycol.

Abstract

L'invention concerne un produit de nettoyage pour surfaces dures qui est appliqué sur la surface à nettoyer à l'aide d'un système de distribution par aspersion se présentant sous la forme d'un tuyau. Ce produit de nettoyage contient un sulfate d'acide gras et/ou un sarcosinate d'acide gras, tel qu'un isopropanol ou un butylglycol. Le produit de nettoyage selon l'invention peut être utilisé dans un procédé pour nettoyer des surfaces dures, en particulier du verre, sans laisser de traces. La décomposition de la mousse de nettoyage au cours du procédé selon l'invention pour nettoyer des surfaces dures peut être perçue acoustiquement sous forme de crépitements.
