The present disclosure also relates to methods of making and using such compounds and compositions. The present disclosure also relates to related precursor compounds and premix compositions.
Claims20
A treatment composition comprising:
- a treatment adjunct, and
- 0.001% to 30% by weight of the treatment composition of a modified amino acid multimer compound,
- wherein the multimer compound comprises a central linking group and from two to six amino acid portions each covalently linked to the central linking group by a heteroatom selected from the group consisting of O, S, and N,
- wherein the central linking group comprises from 3 to 18 carbon atoms,
- wherein the central linking group does not comprise a peptide bond,
- wherein 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,
- wherein the heteroatom is part of the central linking group and is directly bonded to the carbon atom of the carbonyl group of the amino acid portion,
- wherein at least one amino acid portion comprises an organic moiety
- covalently bonded to the nitrogen atom of the amino acid portion,
- wherein the organic moiety comprises a benefit agent residue,
- wherein when one or more bonds that connect the benefit agent residue to the amino acid portion are cleaved, a benefit agent is released,
- wherein the benefit agent comprises an aldehyde moiety, a ketone moiety, or a combination thereof.

9 more elements
A treatment composition comprising:
- a treatment adjunct, and
- 0.001% to 30% by weight of the treatment composition of a modified amino acid multimer compound, wherein the modified amino acid multimer compound is characterized by a structure according to Formula I:
- L[E]t Formula I,
- wherein t is independently an integer from 2 to 6;

- with the proviso that the multimer compound comprises at least two E groups that are moieties according to Formula II,
- wherein * indicates the point of attachment of the E group with L,
- wherein the value of x is from 1 to 9,
- wherein each G is independently selected from the group consisting of —O—, —N(R3)—, and —S—,
- wherein each R3, if present, is independently selected from H or a monovalent moiety with a molecular weight between 14 and 881 Da,
- wherein X, if present, is a suitable charge-balancing counterion,
- wherein each R1 is independently selected from H or a monovalent moiety with a molecular weight between 15 and 507 Da,
- wherein each R2 is independently selected from H and a monovalent moiety with a molecular weight of between 15 and 1000 Da,
- wherein each A group is a monovalent nitrogen-comprising moiety,
- wherein at least one A group comprises an independently selected benefit agent residue that is linked to the rest of the A group by one or more bonds,
- wherein a benefit agent is released when the one or more bonds are cleaved,
- wherein the benefit agent comprises an aldehyde moiety, a ketone moiety, or a combination thereof.
