Abstract: A midly acidic laundry detergent composition is provided for the improved protection of fine fabrics during washing and enhanced removal of generated foam during rinsing in hand wash comprising; a) at least one anionic surfactant; and/or b) at least one nonionic surfactant; c) a rinse-active, pH-sensitive foam control agent comprising a fatty acid; whereby the fatty acid foam control agent remains substantially in acid form at the mildly acidic pH of the wash water so as to be essentially inoperative to suppress foam during washing, and whereby upon rinsing of the laundry with tap water having a pH of from about 7.5 to 8.5 at least of portion of said fatty acid is converted to a soap which functions to suppress foam during rinsing.
