ABSTRACT:
This invention provides a sodium carbonate-based laundry detergent powder which can be utilized in cold water fabric laundering with a minimized remainder of undissolved detergent residue in the wash water. A water-soluble fatty acid salt such as sodium stearate is incorporated as an adherent coating on the detergent granules, in a quantity which is effective for reducing the residue of undissolved sodium carbonate under cold water laundering conditions.
