is oxiclean an optical brightener

OxiClean is a Versatile Stain Remover in a powder form that is activated when added to water (warm or hot water work best). OxiClean targets the stains, rather than the fabric, removing many tough stains on water-washable clothing, carpet, upholstery, and hard surfaces both inside and outside the home.
While OxiClean Versatile Stain Remover is not a laundry detergent, you can use it with detergent to boost your detergent's cleaning power. For detergent, we suggest below optical brightener CXT from Raytop for you.
