Detergent cake containing monoalkylsulfosuccinate and preparation

Claim 2

A CLEANSING BAR COMPRISING FROM ABOUT 40 TO 95% BY WEIGHT OF SUBSTANTIALLY NEUTRAL WATER SOLUBLE ALKALI METAL, ALKALINE EARTH METAL OR AMMONIUM DI-SALTS OF SULFOSUCCINATE MONO ESTERS AND FROM ABOUT 5 TO 60% BY WEIGHT OF A NORMALLY SOLID NON-VOLATILE ORGANIC PLASTICIZER, SAID PLASTICIZER HAVING MELTING POINT SUCH THAT IT IS MOLTEN AT ABOUT 95*C AND IS CHOSEN FROM THE GROUP CONSISTING OF FATTY ACID ESTERS OF POLYHYDRIC ALCOHOLS, SAID ESTERS BEING THE REACTION PRODUCT OF A REACTANT HAVING THEREIN (1) A REACTIVE HYDROXYL GROUP AND, (2) AN ACYCLIC CHAIN HAVING FROM 12 TO 18 CARBON ATOMS WHEREIN BETWEEN 20 AND 100% OF SAID CHAINS ARE ALKYL CHAINS HAVING A CHAIN LENGTH OF 12 CARBON ATOMS, WITH AN ALKALI METAL, ALKALINE EARTH METAL OR AMMONIUM SULFITE, SAID REACTION PRODUCT BEING PRODUCED IN A REACTION MEDIUM INCLUDING SAID PLASTICIZER.

Claim 3

The cleansing bar of claim 1 wherein said salt is selected from the group consisting of alkali metal and ammonium salts of a monoalkylsulfosuccinate.

Claim 4

The cleansing bar of claim 1 wherein said salt is a disodium monoalkylsulfosuccinate.

Claim 5

The cleansing bar of claim 1 wherein titanium dioxide is present in an amount up to about 2 percent by weight.

Claim 6

A PROCESS FOR THE PRODUCTION OF CLEANSING CAKES COMPRISING, REACTING AN ALCOHOL HAVING AN ACYCLIC CHAIN OF FROM 12 TO 18 CARBON ATOMS WHEREIN BETWEEN 20 AND 100% OF SAID CHAINS ARE ALKYL CHAINS HAVING A CHAIN LENGTH OF 12 CARBON ATOMS WITH A REACTANT CHOSEN FROM THE GROUP CONSISTING OF MALEIC ACID, BUTENEDIOIC ACID AND FUMARIC ACID TO FORM A MONOALKYL ESTER, REACTING SAID MONOALKYL ESTER WITH AN ALKALI METAL, ALKALINE EARTH METAL OR AMMONIUM SULPHITE IN THE PRESENCE OF ABOUT 5 TO 10 PERCENT WATER AND A MOLTEN PLASTICIZER CHOSEN FROM THE GROUP CONSISTING OF FATTY ACID ESTERS OF POLYHYDRIC ALCOHOLS TO FORM A WATER SOLUBLE DI-SALT OF MONOALKYLSULFOSUCCINATE, COOLING THE RESULTING PRODUCT, AND FORMING THE COOLED PRODUCT INTO CAKES CONTAINING BETWEEN ABOUT 40 AND 95% BY WEIGHT OF SAID MONOALKYLSULFOSUCCINATE AND FROM ABOUT 5 TO 60% BY WEIGHT OF SAID PLASTICIZER WHICH PLASTICIZES SAID MONOALKYLSULFOSUCCINATE SALT.

Claim 7

A PROCESS FOR THE PRODUCTION OF CLEANSING CAKES COMPRISING, REACTING AN ALCOHOL HAVING AN ACYCLIC CHAIN OF FROM 12 TO 18 CARBON ATOMS WHEREIN BETWEEN 20 AND 100% OF SAID CHAINS ARE ALKYL CHAINS HAVING A CHAIN LENGTH OF 12 CARBON ATOMS WITH A REACTANT CHOSEN FROM THE GROUP CONSISTING OF MALEIC ACID, BUTENEDIOIC ACID AND FUMARIC ACID TO FORM A MONOALKYL ESTER, REACTING SAID MONOALKYL ESTER WITH AN ALKALI METAL, ALKALINE EARTH METAL OR AMMONIUM SULPHITE IN THE PRESENCE OF ABOUT 5 TO 10 PERCENT WATER AND A MOLTEN PLASTICIZER CHOSEN FROM THE GROUP CONSISTING OF FATTY ACID ESTERS OF POLYHYDRIC ALCOHOLS TO FORM A WATER SOLUBLE DI-SALT OF MONOALKYLSULFOSUCCINATE, COOLING THE RESULTING PRODUCT, AND FORMING THE COOLED PRODUCT INTO CAKES CONTAINING BETWEEN ABOUT 40 AND 95% BY WEIGHT OF SAID MONOALKYLSULFOSUCCINATE AND FROM ABOUT 5 TO 60% BY WEIGHT OF SAID PLASTICIZER WHICH PLASTICIZES SAID MONOALKYLSULFOSUCCINATE SALT.

Claim 8

The process of claim 5 wherein said monoalkyl ester is formed by reacting a compound selected from the group consisting of maleic anhydride, fumaric anhydride, maleic acid and fumaric acid with a reactant having therein a reactive hydroxyl group and an acyclic chain having from 12 to 18 carbon atoms wherein at least 20% of said chains are alkyl chains having a chain length of 12 carbon atoms.

Claim 9

The process of claim 5 wherein the cooled product is milled, plodded, cut and pressed to form cakes.

Claim 10

The process of claim 5 wherein the monoalkyl ester is disodium laurylsulfosuccinate.

Claim 11

The process of claim 5 wherein said plasticizer is glyceryl monostearate.
