Abstract

processo para preparar uma partícula de detergente seca por atomização, partícula de detergente seca por atomização obtida a partir do processo e composição detergente para lavagem de roupas. a presente invenção se refere a um processo para preparar uma partícula de detergente particulada de fluxo livre por meio de uma técnica de produção de pasta fluida e secagem por atomização. particularmente, se refere ao processo para preparar uma pasta fluida com menor alcalinidade para a produção de partículas de detergente secas por atomização para lavagem de roupas. é, portanto, um objeto da invenção prover um processo para preparar uma solução detergente para uma partícula de detergente seca por atomização que provê a incorporação de maiores níveis do tensoativo detersivo enquanto fornece boas propriedades de pó. os presentes inventores encontraram que uma partícula de detergente seca por atomização, preparada a partir de uma pasta fluida com alto teor de tensoativo detersivo na presença de um sal silicato e/ou dissilicato de metal alcalinoterroso formado in situ, formado pela reação de um silicato de metal alcalino com um sal de metal alcalinoterroso, e um sal silicato de metal alcalino fornece excelentes propriedades de pó e vida útil prolongada sem aglutinação. é surpreendentemente encontrado que a partícula fornece o ph desejado na solução de lavagem necessária para um bom desempenho de remoção de manchas sem ser agressivo para as mãos ou tecidos.process for preparing a spray-dried detergent particle, spray-dried detergent particle obtained from the process and laundry detergent composition. The present invention relates to a process for preparing a free-flowing particulate detergent particle by means of a slurrying and spray drying technique. particularly, it relates to the process for preparing a slurry with lower alkalinity for producing spray-dried detergent particles for washing clothes. It is, therefore, an object of the invention to provide a process for preparing a detergent solution for a spray-dried detergent particle that provides for the incorporation of higher levels of the detersive surfactant while providing good powder properties. The present inventors have found that a spray-dried detergent particle prepared from a slurry with a high content of detersive surfactant in the presence of an in situ formed alkaline earth metal silicate and/or disilicate salt formed by the reaction of an alkaline earth metal silicate Alkali metal with an alkaline earth metal salt, and an alkali metal silicate salt provides excellent powder properties and extended shelf life without caking. It is surprisingly found that the particle provides the desired pH in the washing solution necessary for good stain removal performance without being harsh on hands or fabrics.
