Abstract

The present invention relates to a consumer goods product comprising a consumer goods product ingredient and a functionalized lignin oligomer, wherein the functionalized lignin oligomer: (a) comprises less than 1 wt % sulphur content; (b) has a number average molecular weight ( M n ) of from 800 Da to 1,800 Da; and (c) comprises at least one functional group selected from carboxyl, ketone, aldehyde, amino and quaternary ammonium, wherein only one type of functional group selected from the group consisting of list is present at a level of at least 0.8 mmol/g, and wherein if any other functional group selected from the group consisting of list is present, it is present at a level of below 0.8 mmol/g, wherein the lignin oligomer is derived from corn, sugar cane, wheat and any combination thereof, and wherein the consumer goods product is selected from an oral care composition, an antiseptic cream, or a detergent composition.

First claim

What is claimed is:

1. A consumer goods product comprising a consumer goods product ingredient and a functionalised lignin oligomer,
wherein the functionalised lignin oligomer
(a) comprises less than about 1 wt % sulphur content;
(b) has a number average molecular weight ( M n ) of from about 800 Da to about 1,800 Da; and
(c) comprises at least one functional group selected from carboxyl, ketone, aldehyde, amino and quaternary ammonium,
wherein only one type of functional group selected from the group consisting of list is present at a level of at least about 0.8 mmol/g,
and wherein if any other functional group selected from the group consisting of list is present, it is present at a level of below about 0.8 mmol/g,
wherein the lignin oligomer is derived from corn, sugar cane, wheat and any combination thereof,
and wherein the consumer goods product is a detergent composition, wherein functional group is a carboxyl.

2. A consumer goods product according to claim 1 , wherein if any other functional group selected from the list is present, it is present at a level of below about 0.6 mmol/g.

3. A consumer goods product according to claim 1 , wherein only one type of functional group selected from the list is present at a level of at least about 0.9 mmol/g.

4. A consumer goods product according to claim 1 , wherein the lignin oligomer has a weight average molecular weight ( M w ) in the range of from about 800 Da to about 5,000 Da.

5. A consumer goods product according to claim 1 , wherein the lignin oligomer has a number average molecular weight ( M n ) in the range of from about 800 Da to about 1,200 Da.

6. A consumer goods product according to claim 1 , wherein the lignin oligomer has a hydrolysable ester content in the range of from about 0.0 mmol/g to about 0.7 mmol/g.

7. A consumer goods product according to claim 1 , wherein the consumer goods product comprises an emollient and/or humectant.

8. A consumer goods product according to claim 1 , wherein the consumer goods product comprises an emulsifier, and wherein the lignin oligomer is in the form of an emulsion.

9. A consumer goods product according to claim 1 , wherein the consumer goods product comprises chitin and/or chitin derivatives.
