Abstract
Fabric treatment compositions that include a treatment adjunct material and certain phenol antioxidants. 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 phenol antioxidants, and methods of making treatment compositions that include such premixes.
Claims19
A fabric treatment composition comprising:
- a treatment adjunct material, and
- from about 0.001% to about 5.0%, by weight of the composition, of an antioxidant according to Formula I:
- wherein A is selected from the group consisting of:
- and
- (iv) mixtures thereof;
- wherein each R1 and R2 is independently selected from —H and —CH3;
- wherein the index m is 0 or 1;
- wherein G, if present, is a divalent moiety CnH2n, where n is 1, 2, or 3;
- wherein the index p is 0 or 1, with the proviso that when m is 0, p is 0;
- wherein Q and each Q′ is independently selected from —O— and —NH—,
- wherein no more than two Q′ is —NH—;
- wherein the index b is 0 or 1;
- wherein L, if present, is at the terminus of a block of the (C2H3R2Q′) units or between two (C2H3R2Q′) units, and is a divalent organic linking moiety with molecular weight from 15 to 300 Da;
- wherein the index q is 3 to 12;
- wherein R3 is selected from H, C1-C4 alkyl, or an independently selected A group;
- and
- wherein when R3 is H, no more than five of R2 on any compound are H, and
- wherein when R3 is C1-C4 alkyl or A, q is at least 4, and at least four of R2 are H,
- with the proviso that when the A group is Formula III and both R1 of the A group are H, at least one of R2 must be —CH3;
- wherein the antioxidant according to Formula I comprises an A group according to Formula III.
A process of making a fabric care composition, the process comprising combining an antioxidant with a treatment adjunct material,
- wherein the antioxidant is a phenol antioxidant according to Formula I:
- wherein A is selected from the group consisting of:
- and
- (iv) mixtures thereof;
- wherein each R1 and R2 is independently selected from —H and —CH3;
- wherein the index m is 0 or 1;
- wherein G, if present, is a divalent moiety CnH2n, where n is 1, 2, or 3;
- wherein the index p is 0 or 1, with the proviso that when m is 0, p is 0;
- wherein Q and each Q′ is independently selected from —O— and —NH—,
- wherein no more than two Q′ is —NH—;
- wherein the index b is 0 or 1;
- wherein L, if present, is at the terminus of a block of the (C2H3R2Q′) units or between two (C2H3R2Q′) units, and is a divalent organic linking moiety with molecular weight from 15 to 300 Da;
- wherein the index q is 3 to 12;
- wherein R3 is selected from H, C1-C4 alkyl, or an independently selected A group;
- and
- wherein when R3 is H, no more than five of R2 on any compound are H, and
- wherein when R3 is C1-C4 alkyl or A, q is at least 4, and at least four of R2 are H,
- with the proviso that when the A group is Formula III and both R1 of the A group are H, at least one of R2 must be —CH3;
- wherein the antioxidant according to Formula I comprises an A group according to Formula III.
A fabric treatment composition comprising:
- a treatment adjunct material, and
- from about 0.001% to about 5.0%, by weight of the composition, of an antioxidant according to Formula I:
- wherein A is
- and
- wherein each R1 and R2 is independently selected from —H and —CH3;
- wherein Q and each Q′ is independently selected from —O— and —NH—,
- wherein no more than two Q′ is —NH—;
- wherein the index b is 0 or 1;
- wherein L, if present, is at the terminus of a block of the (C2H3R2Q′) units or between two (C2H3R2Q′) units, and is a divalent organic linking moiety with molecular weight from 15 to 300 Da;
- wherein the index q is 3 to 12;
- wherein R3 is selected from H, C1-C4 alkyl, or an independently selected A group;
- and
- wherein when R3 is H, no more than five of R2 on any compound are H, and
