Abstract
A polish composition includes a siloxane polymer of the formula wherein each group A independently represents an alkyl group having up to 6 carbon atoms, M represents an alkyl group having up to 6 carbon atoms and Q represents an alkyl group, wherein a proportion of the groups Q have more than 20 carbon atoms and the remainder have up to 6 carbon atoms, and wherein “x” is an integer selected to give a molecular weight of the polymer III in the range 3,000–30,000. In prior polish compositions the radical “Q” have been of shorter chain lengths. We have found that a longer chain length promotes reduced smearing.

A container containing a liquid polish composition comprising from 0.1% to 5% of a siloxane polymer of the formula
- wherein each group A independently represents an alkyl group having up to 6 carbon atoms, M represents an alkyl group having up to 6 carbon atoms and Q represents an alkyl group, wherein a proportion of the groups Q have more than 20 carbon atoms and the remainder have up to 6 carbon atoms, and wherein “x”is an integer selected to give a molecular weight of the polymer III in the range 3,000–30,000, from 0.2% to 2% surfactant, from 0.5% to 20% hydrocarbon solvent, from 1 to 5% poly(di-C1-6 alkyl) siloxane oil, 0 to 5% additional components and the balance water wherein the container includes spray emission means.
A method of polishing a smooth hard surface, the method comprising the step of applying a polish composition, comprising from 0.1% to 5% of a siloxane polymer having the formula:
- wherein each group A independently represents an alkyl group having up to 6 carbon atoms, M represents an alkyl group having up to 6 carbon atoms and Q represents an alkyl group, wherein a proportion of the groups Q have more than 20 carbon atoms and the remainder have up to 6 carbon atoms, and wherein “x”is an integer selected to give a molecular weight of the polymer III in the range 3,000–30,000, from 0.2% to 2% surfactant, from 0.5% to 20% hydrocarbon solvent from 1% to 5% poly siloxane oil, 0 to 5% additional components and the balance water and rubbing the surface with a cloth.
