Abstract
This invention provides a powder carbonate-based laundry detergent which can be utilized in cold water fabric laundering with a minimized remainder of undissolved detergent residue in the wash water. A particulate anionic surfactant ingredient such as sodium lauryl sulfate is incorporated by dry blending with detergent granules to form an adherent coating of fine particles of anionic surfactant on the detergent granules, in a quantity which is effective for reducing the residue of undissolved detergent under cold water laundering conditions.
