Independent Claim
92 words
A DETERGENT COMPOSITION CONSISTING ESSENTIALLY OF A MIXTURE OF 75 TO 97% BY WEIGHT OF A SOAP WITH 25 TO 3% BY WEIGHT OF A SUCROSE ESTER, SAID SUCROSE ESTER COMPRISING AT LEAST ONE SUCROSE ESTER OF A FATTY ACID HAVING 12 TO 14 CARBONATOMS AND AT LEAST 70% BY WEIGHT OF SAID SUCROSE ESTER BEING MONO- AND DI-ESTERS, THE DEGREE OF SUBSTITUTION OF SAID SUCROSE ESTER GIVEN BY THE AVERAGE VALUE OF THE NUMBER OF ESTERIFIED FATTY AND MOLECULES PER ONE SUCROSE MOLECULE BEING WITHIN THE RANGE OF 1.5 TO 3.5.
Claim 2
Dependent Claim
92 words
A DETERGENT COMPOSITION CONSISTING ESSENTIALLY OF A MIXTURE OF 75 TO 97% BY WEIGHT OF A SOAP WITH 25 TO 3% BY WEIGHT OF A SUCROSE ESTER, SAID SUCROSE ESTER COMPRISING AT LEAST ONE SUCROSE ESTER OF A FATTY ACID HAVING 12 TO 14 CARBONATOMS AND AT LEAST 70% BY WEIGHT OF SAID SUCROSE ESTER BEING MONO- AND DI-ESTERS, THE DEGREE OF SUBSTITUTION OF SAID SUCROSE ESTER GIVEN BY THE AVERAGE VALUE OF THE NUMBER OF ESTERIFIED FATTY AND MOLECULES PER ONE SUCROSE MOLECULE BEING WITHIN THE RANGE OF 1.5 TO 3.5.
