STABILIZED SODIUM CARBONATE PEROXYHYDRATE

摘要

The invention relates to stabilized sodium carbonate peroxyhydrate (SCPH) particles having a coating layer comprising a mixture of lithium sulphate an d sodium sulphate, said sulphates preferably being present in substantially equimolar amounts. The coated SCPH particles can be prepared by fluidized be d coating. The coated SCPH particles have good stability when used in detergen ts containing zeolites.
