Abstract
Integral powdered abrasive soaps are formulated by in-situ reacting on an abrasive, an acid or base component with an antipodal base or acid component. Since the acid or base component resides on the abrasive particles, the formed soap also resides on the abrasive particles and often forms a coating. The in-situ soap is a dry powder and is flowable. The abrasive can be a crushable abrasive so that, upon the application of slight pressure thereto, it breaks down into small particles and aids in cleaning.
Claims17
A free flowing soap powder, comprising:
- the in-situ formation of a neat abrasive soap, said neat abrasive soap being the in-situ reaction product on abrasive particles of an initial precursor, selected from the group consisting of acid and base soap forming components and a final precursor selected from the group consisting of acid and base soap forming components, said final precursor being antipodal of said initial precursor;
- wherein said initial precursor is a liquid, said acid component is selected from the group consisting of fatty acids having from about 9 to about 30 carbon atoms and said base component is selected from the group consisting of morpholine and alkanolamines having from 2 to 12 carbon atoms;
- said abrasive particles being present in an amount sufficient for said abrasive soap powder to be free flowing.
A free flowing abrasive soap powder, comprising:
- abrasive particles and a soap formed in-situ on said abrasive particles, wherein said soap contains an acid portion selected from the group consisting of fatty acids having from about 9 to about 30 carbon atoms and a base portion selected from the group consisting of morpholine and alkanolamines having from 2 to about 12 carbon atoms;
- said abrasive particles being present in an amount sufficient for said abrasive soap powder to be free flowing.
A process for the in-situ formation of a soap on an abrasive particle to form a free flowing soap powder product, comprising the steps of:
- applying an initial precursor to at least one type of an abrasive particle, and in-situ forming an integral abrasive soap powder by reacting said initial precursor with a final precursor, wherein said initial precursor is a liquid selected from the group consisting of acid and base soap forming components and said final precursor is selected from the group consisting of acid and base soap forming components and
- wherein said acid component is derived from a compound selected from the group consisting of fatty acids and fatty acid esters having from about 9 to about 30 carbon atoms, and said base component is selected from the group consisting of morpholine and alkanolamines having from 2 to 12 carbon atoms;
- said abrasive particles being present in an amount sufficient for said abrasive soap powder to be free flowing.
