Abstract
The present disclosure relates to a method of cleaning a surface to be cleaned, wherein said surface is selected from a household item or a vehicle, said method comprising contacting said surface with an aqueous solution comprising a polyester polyquaternary (PEPQ) compound. Formulations useful for this purpose are also disclosed.
Claims18
A method of cleaning a surface of a household item or a vehicle, said method comprising contacting the surface with an aqueous solution comprising a polyester polyquaternary (PEPQ) compound.
(canceled)
A method of cleaning a surface of a household item or a vehicle, said method comprising contacting the surface with an aqueous solution comprising a polyester polyquaternary (PEPQ) compound having the formula:
- where R4 is a C6-23 aliphatic, saturated or unsaturated, branched or linear group;
- AO is an alkyleneoxy group having 2-4 carbon atoms, the oxygen atom of which is bonded to the adjacent carbonyl group;
- each x is independently from 2-20;
- R2 is an alkylene radical of formula —(CH2)2—, wherein z is from 2 to 4, and the alkylene radical is optionally substituted by 1 or 2 substituents independently selected from —OH, —COOH, and —COOR3;
- R3 is a C1-4-alkyl group;
- R5 is a C1-C4 alkyl group or a benzyl group;
- R6 is a hydrocarbyl group having 12 to 24 carbon atoms or a partial or wholly quaternized derivative thereof;
- X− is an anion derived from the alkylating agent;
- t is 1, and p is a number from 3-15.
A method of cleaning a surface of a household item or a vehicle, said method comprising contacting the surface with an aqueous solution comprising a polyester polyquaternary (PEPQ) compound having the formula:
- where R is a hydrocarbyl group having from 11 to 21 carbon atoms that is optionally substituted;
- each R′ is independently H or R(C═O);
- k is an integer from 2-7;
- m is an integer from 1-3;
- and each n is independently an integer from 0-10.
