Abstract

L'invention concerne du sulfonate d'alcane secondaire comprenant essentiellement du sulfonate d'alcane secondaire solide à fines particules et un additif. Ce sulfonate d'alcane secondaire granulaire s'obtient par broyage et mélange de sulfonate d'alcane secondaire avec un additif, de préférence de l'acide silicique à fines particules. Le sulfonate d'alcane ainsi obtenu s'utilise dans des détergents et des nettoyants ou directement pour produire des extrudats, des pièces moulées ou des produits compactés.
