Abstract
Fabric treatment compositions that include a treatment adjunct material and certain antioxidant multimer compounds. Process of treating fabrics that include at least one source of malodor by contacting the fabric with such fabric treatment compositions. Premix compositions that include certain antioxidant multimer compounds, and methods of making treatment compositions that include such premixes.
Claims30
A treatment composition comprising:
- a treatment adjunct, and
- an antioxidant multimer material,
- wherein the antioxidant multimer material comprises an antioxidant multimer compound that comprises a central linking group and from three to six antioxidant moieties covalently linked to the central linking group;
- wherein the central linking group comprises from 2 to 18 carbon atoms and at least two heteroatoms when at least one of the heteroatoms is a nitrogen, or at least three heteroatoms if there are no nitrogen atoms in the central linking group,
- wherein the heteroatoms are independently selected from oxygen, sulfur, or nitrogen,
- wherein each antioxidant moiety is linked directly or indirectly to
- the central linking group at one of the at least two heteroatoms,
- wherein each antioxidant moiety comprises a phenol group,
- wherein at least one antioxidant moiety comprises an organic moiety covalently bonded ortho- to the phenol —OH group,
- wherein the organic moiety comprises an alkyl group of 1 to 4 carbon atoms,
- wherein at least one antioxidant moiety comprising an organic moiety covalently bonded ortho- to the phenol OH group further comprises a substituent on the other position ortho- to the phenol OH group selected from H and an alkyl group of 1 to 4 carbon atoms,
- wherein each antioxidant moiety optionally comprises a carbonyl group, wherein at least one antioxidant moiety is bound to a divalent polymeric moiety at a first end of the polymeric moiety, wherein a carbon atom at a second end of the divalent polymeric moiety is bound to a heteroatom of the central linking group,
- wherein the divalent polymer moiety comprises at least three contiguous, independently selected units selected each having the empirical formula QCnH2n where n is independently selected from 2 to 4, wherein each Q is independently O, S, or NR4, wherein each R4, if present, is independently H or C1-C4 alkyl.
