Laundry detergent product with improved cold water residue properties

摘要

This invention provides a high carbonate-low phosphate powder laundry detergent formulation which can be utilized in cold water fabric laundering with a minimized remainder of undissolved detergent residue in the wash water. An essential aspect of the laundry detergent formulation is a content of a partially sulfated and neutralized blend of ethoxylated alcohol surfactant constituents. A preferred type of surfactant ingredient is a Neodol 23-3 derived type of blend which is 50-65 percent sulfated and neutralized. Another essential aspect is a content of polyethylene glycol ingredient which increases the solubility of the laundry detergent solids in the wash water.
