BLEACH-FREE LAUNDRY POWDER DETERGENT WITH NANOPARTICLES

摘要

A bleach-free laundry detergent composition containing zero-valent iron nanoparticles. A small amount of nanoparticles with a size range of about 100 nm to about 500 nm replace the bleach and consequently the bleach activator in the laundry detergent composition. These nanoparticles are capable of oxidization which makes them an appropriate alternative for the bleach in a laundry detergent.
