Dependent Claim
112 words
A PARTICULATE SOAP PRODUCT CONSISTING OF AN INNER PORTION OF A SOAP COMPOSITION CONSISTING ESSENTIALLY OF SODIUM SOAPS CONTAINING INSUFFICIENT SOAPS OF SATURATED FATTY ACIDS HAVING 8 TO 14 CARBON ATOMS TO PREVENT BALLING AND AT LEAST 11/2% AND NOT MORE THAN 50% OF SODIUM SILICATE UNIFORMLY DISTRIBUTED THEREIN, AND A CRUST PORTION COMPRISING THE REACTION PRODUCTS OF SILICATE AND SATURATED FATTY ACIDS HAVING FROM 8 TO 14 CARBON ATOMS IN THE MOLECULE, THE AMOUNT OF SAID FATTY ACID BEING EQUAL TO FROM 1% TO ABOUT 7% OF THE WEIGHT OF THE SOAP PARTICLE, THE SIO2/NA2O RATIO OF THE SILICATE IN THE CRUST PORTION BEING GREATER THAN THAT OF SAID INNER PORTION.
