Claims20
A treatment composition comprising:
- a treatment adjunct, and a modified amino acid dimer compound, wherein:
- i) the dimer compound comprises two amino acid portions covalently connected by a linking group;
- ii) each amino acid portion comprises a carbon backbone comprising one or more carbon atoms, a carbonyl group that comprises a carbon atom, and a nitrogen atom;
- iii) at least one of the two amino acid portions comprises one or more hydrophobic moieties covalently connected to a heteroatom selected from O, S, or N;
- iv) the heteroatom is directly bound to the carbon of the carbonyl group of the amino acid portion;
- v) the linking group is a divalent moiety that is bound to a carbon atom of the carbon backbone of each amino acid portion;
- vi) the linking group does not comprise a peptide bond;
- vii) each of the backbone carbon atoms that is bonded to the linking group is further bonded directly to the nitrogen atom of the respective amino acid portion;
- viii) at least one amino acid portion comprises an organic moiety covalently bonded to the nitrogen atom of the amino acid portion;
- ix) the organic moiety comprises a benefit agent residue that is capable of cleaving to release a benefit agent;
- and
- x) the benefit agent comprises an aldehyde moiety, a ketone moiety, or a combination thereof.

A treatment composition comprising:
- a treatment adjunct, and
- a modified amino acid dimer compound, wherein the modified amino acid dimer compound is characterized by a structure according to Formula I:
- wherein:
- i) L is a linking group comprising 1 to 18 chain atoms;
- ii) the linking group does not comprise a peptide bond;
- iii) the chain atoms are selected from carbon atoms, oxygen atoms, nitrogen atoms, sulfur atoms, or combinations thereof;
- iv) each Q is an independently selected carbon-containing core comprising from 1 to 9 carbon atoms;
- v) each G is independently selected from the group consisting of —O—, —N(R6)—, or —S—, and each G group is the same;
- vi) R6, if present, is selected from —H or a monovalent moiety with a molecular weight of from about 15 to about 255 Da;
- vii) each R3 is independently selected from H, X, or a monovalent moiety with a molecular weight of from about 15 to about 881 Da;
- viii) X is a suitable charge balancing counterion, with the proviso that at least one R3 is the monovalent moiety;
- ix) the monovalent moiety of R3 and the monovalent moiety of R6, when present, taken together comprise a total of 5 to 34 chain atoms;
- x) each A group is a monovalent nitrogen-comprising moiety;
- xi) at least one A group comprises a benefit agent residue that is capable of cleaving to release a benefit agent;
- and
- xii) the benefit agent comprises an aldehyde moiety, a ketone moiety, or a combination thereof.
