LAUNDRY PRETREATMENT WITH PEROXIDE BLEACHES CONTAINING CHELATORS FOR IRON, COPPER OR MANGANESE FOR REDUCED FABRIC DAMAGE.

摘要

The present invention relates to the use of a liquid composition comprising a peroxygen bleach and a compound chelating copper and/or iron and/or manganese, for pretreating fabrics before said fabrics are washed, whereby the loss of tensile strength in said fabrics is reduced. The present invention further encompasses a process for pretreating soiled fabrics as well as compositions suitable to be used in said process.
