Abstract
The present invention relates to a detergent composition having from 3 to 75 percent by weight of at least one surfactant; and from 0.01 to 5 percent by weight percent of a copolymer composed of from 25 to 75 mole percent of at least one amine-functional monomer, and from 75 to 25 mole percent of at least one hydrophobic ethylenically unsaturated monomer, wherein said amine-functional monomer is not a quaternized amine, and wherein said copolymer has been at least partially neutralized. The detergent composition having the copolymers provides color protection and anti-pill properties in laundry applications.
Claims17
A detergent composition comprising:
- a) from 3 to 75 percent by weight of at least one surfactant;
- and
- b) from 0.01 to 5 percent by weight percent of a copolymer comprising:
- 1) from 25 to 75 mole percent of at least one amine-functional monomer;
- 2) from 25 to 75 mole percent of at least one hydrophobic ethylenically unsaturated monomer;
- 3) from 0 to 50 mole percent of an hydroxy functional ethylenically unsaturated monomer;
- 4) from 0 to 10 mole percent of a diethylenically unsaturated monomer or polyfunctional mercaptan;
- wherein said amine-functional monomer is not a quaternized amine, and wherein said copolymer has been at least partially neutralized.
A fibrous material having thereon a protective coating comprising:
- a) a woven or knit fibrous substrate;
- b) a protective coating comprising a copolymer, wherein said copolymer comprises
- 1) from 25 to 75 mole percent of at least one amine-functional monomer;
- 2) from 75 to 25 mole percent of at least one hydrophobic ethylenically unsaturated
- 3) from 0 to 50 mole percent of an hydroxy functional ethylenically unsaturated monomer;
- 4) from 0 to 10 mole percent of a diethylenically unsaturated monomer or polyfunctional
- wherein said amine functional monomer is not a quaternized amine, and wherein said copolymer has been at least partially neutralized.
A method for the delivery of an active ingredient comprising:
- a) associating, coating or encapsulating an active ingredient a copolymer comprising
- 1) from 25 to 75 mole percent of at least one amine-functional monomer;
- 2) from 25 to 75 mole percent of at least one hydrophobic ethylenically unsaturated monomer;
- 3) from 0 to 50 mole percent of an hydroxy functional ethylenically unsaturated monomer;
- 4) from 0 to 10 mole percent of a diethylenically unsaturated monomer or polyfunctional mercaptan;
- wherein said amine-functional monomer is not a quaternized amine, and wherein said copolymer has been at least partially neutralized,
- b) introducing said coated or encapsulated active ingredient into an aqueous environment, resulting in the release of the active ingredient.
