Abstract

Une composition adoucissante pour textiles, sous forme solide, par exemple sous forme d'une poudre ou de comprimés, contient une lipase. En ajoutant une lipase à une composition solide plutôt que liquide, on améliore la stabilité de l'enzyme pendant la durée de conservation de la composition. En outre, on peut réduire l'hydrolyse des composés adoucissants pour textiles, composés qui sont enclins à la dégradation hydrolytique comme, par exemple, les esters.
