Abstract

New cleaning compositions including novel suds boosting and stabilization biopolymers containing alkoxy, anionic and nitrogen containing substitution are disclosed. In particular, cleaning compositions including suds boosting and stabilization biopolymers containing modified polysaccharides having alkoxy, anionic and nitrogen containing substitution and methods of forming the same are disclosed.

Claims

1. A cleaning composition comprising a suds boosting and stabilizing biopolymer comprising a randomly substituted linear or branched biopolymer backbone having a structure:

2. The cleaning composition of claim 1, wherein the randomly substituted polymer backbone is a randomly substituted starch backbone.

3. The cleaning composition of claim 1, further comprising at least one or more adjuncts selected from the group consisting of bleach activators, surfactants, builders, chelating agents, dye transfer inhibiting agents, dispersants, enzymes, enzyme stabilizers, catalytic metal complexes, polymeric dispersing agents, clay and soil removal/anti-redeposition agents, brighteners, suds suppressors, dyes, perfumes, perfume delivery systems, structure elasticizing agents, fabric softeners, carriers, hydrotropes, processing aids, and pigments.

4. The cleaning composition of claim 1, wherein the cleaning composition is a fabric care product selected from the group consisting of liquid laundry detergents, solid laundry detergents, laundry soap products, laundry spray treatment products, a dish washing detergent, a beauty care detergent, a shampoo, and a household cleaning detergent.

5. A cleaning composition comprising a suds boosting and stabilizing biopolymer comprising a randomly substituted polymer backbone comprising unsubstituted and substituted 1-4 alpha-D glucopyranose residues or 1-6 alpha D-glucopyranose residues and having a general structure according to Formula I:

6. The cleaning composition of claim 5, wherein (OR⁷) has a structure —

O—

CH(R¹⁰)CH₂—

, wherein R¹⁰ is methyl or ethyl.

7. The cleaning composition of claim 5, wherein the suds boosting and stabilizing biopolymer comprises a blend of at least a first randomly substituted polymer having a structure according to Formula I and a weight average molecular weight ranging from 10,000 Daltons to 1,000,000 Daltons and a second randomly substituted polymer having a structure according to Formula I and a weight average molecular weight ranging from 1,000,000 Daltons to 100,000,000 Daltons.

8. The cleaning composition of claim 5, wherein the randomly substituted polymer backbone is a randomly substituted starch backbone having the general structure according to Formula IB:

9.
