Definitions

  • the present invention is in the field of hard surface cleaning compositions; in particular antifoaming composition for use in detergent compositions having foaming and cleaning characteristics in the main wash, yet significant foam reduction during rinse.
  • One way of saving water is to reuse the water and another way is to reduce the amount of water being used.
  • Washing processes including laundry, dishwashing and other household cleaning processes, require large amounts of water throughout the world. These are daily chores in which the use of water and a detergent cannot be avoided. Consumers usually like to see a lot of foam while washing as they associate foaming with detergent efficiency. However, it's rinsing that often takes a lot of effort and uses excess of water. This is predominantly caused by the consumer perception that they need to continue rinsing until the rinse water is no longer foaming. Thus, it has been a challenge to provide consumers with a cleaning composition that maintains the foam in the main wash while exhibiting an antifoaming effect during rinse.
  • US 4,869,842 discloses a liquid cleaning composition for use as a hard surface cleaner, comprising a base liquid composition comprising a base composition of an anionic surfactant, a non-ionic surfactant, a non-polar grease removal solvent, a water soluble detergent builder salt, optionally a perfume and a dye and water; and an abrasive.

Abstract

La présente invention porte sur le domaine des compositions de nettoyage de surfaces dures. Fournir aux consommateurs une composition de nettoyage qui conserve sa mousse pendant le lavage principal tout en manifestant un effet antimousse lors du rinçage est un véritable défi. Un objet de la présente invention est donc de fournir une économie d'eau dans les processus ménagers en fournissant une composition antimousse présentant un effet antimousse uniquement pendant le rinçage, tout en conservant des caractéristiques de moussage pendant le lavage principal. On a découvert qu'un effet antimousse peut être obtenu uniquement pendant le rinçage lors de processus de nettoyage de surfaces dures grâce à une composition antimousse comprenant essentiellement un agent tensioactif non ionique, un acide gras et une particule hydrophobe, la particule hydrophobe étant un abrasif inorganique revêtu d'un acide gras.
