Osmose Bleach Powder (Sodium Percarbonate)


The Osmosis Whitening Agent revives whites and colors by dislodging residues present in fabrics. The active oxygen it releases on contact with water makes it a powerful stain remover and degreaser in addition to being a water softener to optimize the action of laundry detergent. This product is used as a soak for yellowed, grayed or stained fabrics.  It can also be combined with laundry detergent for maintenance washes.

 *Large volumes are available in-store.
