Abstract

L'invention concerne des granulés colorés présentant une stabilité de couleur améliorée. Les granulés colorés comprennent (a) un noyau coloré comprenant un colorant et (b) un revêtement de sel entourant le noyau constituant de 1 à 50 % p/p du granulé et comprenant au moins 60 % p/p d'un sel ayant une humidité relative constante à 20 °C d'au moins 60 % (sulfate de sodium), qui forme une couche continue ayant peu ou pas de trous. L'invention concerne également une composition détergente solide comprenant un tensioactif, un adjuvant et le granulé coloré, comprenant en outre de préférence un composant de système de blanchiment.
