This invention relates to an improved, premeasured, through the wash, dry laundry active product comprised of an oxidation resistant tissue and dry laundry actives contained therein. The oxidation resistant (OR) tissue is particularly useful as a durable substrate and a convenient vehicle for delivering laundry additives to a wash liquor comprising bleach. The improved products of this invention are storage stable, deliver premeasured actives and survive the wash without tearing or shredding.
