Definitions

  • the present invention relates to a laundry cleaning composition; in particular, a solid laundry detergent composition having a desirable foam profile during the laundering process.
  • Synthetic detergents are widely used for laundering fabrics, due to their efficiency in cleaning and stain removal.
  • formulated laundry detergent composition includes various additives to provide improved cleaning and sensorial benefits. Proper foam level is a sensorial benefit which most consumers desire during the laundering process.
  • Foaming or sudsing is an important factor to consider when formulating a detergent composition. Foam is a significant consumer cue and acts as the primary reason by which a consumer perceives that a composition is having a cleaning effect. Unfortunately, while foam is easy to generate, it also needs to be removed from the substrate after cleaning. High volume of foam in the washing cycle typically results in foam being carried over to the rinse liquor and requiring additional time, energy, and water to thoroughly rinse the laundered articles. It is therefore advantageous to have high foam volume generation at early stages in the wash cycle for consumer acceptance. Followinged by quick collapse of the foam to a lower volume toward the end of the wash cycle, these aspects of the foaming profile of a detergent composition allows for complete cleaning and minimum wastage of clean water.

Abstract

La présente invention concerne une composition détergente pour la lessive possédant un profil de moussage souhaitable pendant le processus de blanchissage. Un objet de la présente invention consiste à procurer une composition détergente présentant un bon profil de moussage. Encore un autre objet de la présente invention consiste à procurer une composition détergente réduisant la quantité d'eau requise pour le rinçage. Les présents inventeurs ont découvert qu'une composition détergente possédant un tensioactif détersif anionique primaire spécialement sélectionné, lorsqu'elle est présente en combinaison avec un cosurfactant et un agent anti-mousse, permet de manière surprenante une bonne formation de mousse dans la phase de lavage tout en éliminant rapidement la mousse pendant la phase de rinçage.
