  • the present invention relates to bleach-containing detergents. This technology may find an application in laundry detergent compositions, soaking detergent compositions, or any other compositions for household applications or the like.
  • perborate As a source of available oxygen in granular bleach-containing detergent compositions for use in hot or humid environments.
  • the inclusion of a bleaching system in a granular detergent formulation helps to improve the cleaning performance of the detergent and is common practice in the laundry industry.
  • the inventors have found that in granular bleach-containing detergent compositions, it is the perborate that causes the increase in the mean particle size of the detergent composition during storage in conditions of high temperature and high relative humidity. Whilst not intending to be bound by theory, it is thought that in these conditions, sodium perborate monohydrate is hydrated to sodium perborate tetrahydrate. Sodium perborate tetrahydrate forms a gel that binds other detergent ingredients, thus forming detergent components of an irregular and increased size. This increase in the mean particle size of the detergent components results in a product that is of coarse appearance and not acceptable to the consumers.
  • the inventors have suprisingly found that when selected sodium percarbonate is used instead of sodium perborate as a source of available oxygen in a granular bleach- containing detergent composition with a bulk density of less than 570g/l, the problem of increasing particle sizes is alleviated. It has been found that when such products are stored under hot and/or humid conditions, for example, after being simultaneously exposed to 32°C and 80% relative humidity for 24 hours, the detergent composition retains its main particle size, in that it has a mean particle size of 100% to 130% of the original mean particle size. This results in a product that remains attractive to the consumer, which is of great benefit to the laundry industry and is especially applicable to handwash applications.
  • the inventors have found that, after storage in such, the detergent composition retains its bulk density, in that it has a bulk density of 90% to 100% of the original bulk density. This results in a product that can still be effectively and accurately dosed during the washing process.

Abstract

La présente invention porte sur une composition détergente ayant une masse volumique apparente inférieure à 570g/1 et qui se caractérise en ce que la source de percarbonate comprend un sel de percarbonate, et en ce que, après avoir été exposée simultanément, pendant 24 heures, à 32 °C et à une humidité relative de 80 %, la composition détergente a une granulométrie moyenne comprise entre 100 % et 130 % de sa granulométrie d'origine. La présente invention porte également sur une composition détergente granulaire contenant un agent de blanchiment et dont la masse volumique apparente est inférieure à 570g/1. Cette composition comprend un source de percarbonate et moins de 0.06 % en poids d'un silicone extractible supprimant la lessive de savon. La source de percarbonate comprend un sel de percarbonate et se caractérise en ce qu'elle possède moins de 2 % en poids d'ions de chlorure. La composition détergente peut également être utilisée dans des zones climatiques à température élevée et à forte humidité relative.
