Zusammenfassung: | THERE IS DISCLOSED A DETERGENT COMPOSITION CONTAINING, AS AN ESSENTIAL INGREDIENT, AT LEAST ONE MEMBER SELECTED FROM ALPHA-SULFO-FATTY ACID DERIVATIVES AS REPRESENTED BY FOLLOWING FORMULAS (2) AND (3): R2CHCOO (AO)M COCHR3 l l (2) SO3M2 SO3M3 R4CHCOO (AO)N R5 l (3) SO3M4WHEREIN R2 AND R3, ARE EACH AN ALKYL GROUP OR AN ALKENYL GROUP, EACH HAVING FROM 6 TO 24 CARBON ATOMS;R4 IS AN ALKYL GROUP HAVING FROM 6 TO 24 CARBON ATOMS;R5 IS AN ALKYL GROUP HAVING FROM 1 TO 4 CARBON ATOMS;M2, M3 AND M4 ARE EACH A HYDROGEN ATOM OR A CATION CAPABLE OF FORMING A SALT;AO IS AN OXYALKYLENE GROUP; AND M AND N ARE EACH A POSITIVE INTEGER.THE DETERGENT COMPOSITIONS ARE VERY LOW IN IRRITABILITY TO THE BODY AND HAVE A LOW CRITICAL MICELLE CONCENTRATION AND A LOW KRAFFT POINT. FURTHER, THEY ARE HIGHLY SOLUBLE IN WATER AND THEY CAN BE USED IN THE FORM OF POWDER OR LIQUID. |
