LIGHT-DUTY LIQUID DETERGENT COMPOSITIONS HAVING ENHANCED SKIN MILDNESS PROPERTIES Vincent P. Heuring ABSTRACT OF THE DISCLOSURE Liquid detergent compositions are disclosed having excellent sudsing and mildness characteristics and consisting essentially of: 1) from 10% to 35% by weight of an alkyl ether sulfate containing 10 to 15 carbon atoms in the alkyl group and an average degree of ethoxy- lation of from 3.5 to 6.5, the alkyl ether prior to sulfation and neutralization having been sub- jected to stripping to remove substantially all unethoxylated and the majority of the mono- and diethoxylated material; 2) from 1% to 5% by weight of a primary alkyl sulfate of 10 to 16 carbon atoms; 3) from about 0.25% to 3% by weight of a water-soluble alkali earth metal salt, preferably magnesium; and 4) the balance water. Preferred compositions also include alkyl glyceryl ether sulfonate and trialkyl amine oxide surfactants, together with a solubilizing agent. The compositions display desirable sudsing properties and are outstandingly mild to the skin.
