2 . A consumer goods product according to claim 1 , wherein the functionalised lignin oligomer is crosslinked, and comprises at least one bonding motif of the following types between the lignin backbone and the functional group:
lignin_backbone-(‘L’) m -‘Si’-(L′) p -lignin_backbone
wherein ‘lignin_backbone’ is a part of the lignin structural backbone; wherein ‘L’ is a linking motif independently selected from the group: —O—, —C(O)O—, —C(O)NR′—, NR′—, and —NR′C(O)NR′—, wherein R′ is H or C 1 -C 6 alkyl, wherein m is 0 or 1; wherein ‘S’ is a spacing unit selected from the group: linear or branched, saturated or unsaturated, substituted or unsubstituted C 2 -C 18 alkyl chain or a linear or branched, saturated or unsaturated, substituted or unsubstituted secondary hydroxy C 2 -C 18 alkyl chain, wherein p is 0 or 1; and wherein ‘Si’ is a polysiloxane.

3 . A consumer goods product according to claim 1 , wherein the functionalised lignin oligomer is non-crosslinked and comprises a functional group having the structure comprising the functional group:
lignin_backbone-O-L-‘Si’
wherein ‘lignin_backbone’ is the lignin structural backbone; wherein L is a linker; and wherein ‘Si’ is a polysiloxane, wherein L has the chemical structure:

wherein R 1 and R 2 are independently selected from H and linear or branched, saturated or unsaturated, substituted or unsubstituted C 1 to C 18 alkyl;
wherein X is independently selected from R 1 , R 2 , hydroxyl, amine, ether and ester;
wherein L′ is a linking structural motif selected from linear or branched, saturated or unsaturated, substituted or unsubstituted C 1 to C 18 alkyl;
wherein ‘Si’ is a polysiloxane;
or
|—C′-L′-|  (b)

wherein —C′— motif is a connecting motif selected from: —C(═O)—, —OC(═O)—, —C(═O)NR′—, wherein R′ is selected from H, or C 1 -C 6 alkyl;
wherein L′ is a linking structural motif selected from linear or branched, saturated or unsaturated, substituted or unsubstituted C 1 to C 18 alkyl;
wherein ‘Si’ is a polysiloxane.

4 . A consumer goods product according to claim 1 , wherein the functionalised lignin oligomer is crosslinked and comprises a functional group having the structure comprising the functional group:
lignin_backbone-O-L-‘Si′’-L-O-lignin_backbone
wherein ‘lignin_backbone’ is the lignin structural backbone; wherein ‘Si′’ is a polysiloxane; wherein L is a structural motif selected from:

wherein R 1 and R 2 are independently selected H and linear or branched, saturated or unsaturated, substituted or unsubstituted C 1 to C 18 alkyl;
wherein X is independently selected from H, linear or branched, saturated or unsaturated, substituted or unsubstituted C 1 to C 18 alkyl, substituted or unsubstituted aromatic or heteroaromatic groups, hydroxyl, amino, ether and ester;
wherein L′ is a linking structural motif independently selected from linear or branched, saturated or unsaturated, substituted or unsubstituted C 1 to C 18 alkyl;
wherein ‘Si′’ is a polysiloxane;
or
|—C′-L′-‘Si′’-L′-C′-|  (b)

wherein the C′— motif is a connecting motif selected from: —C(═O)—, —C(═O)O—, —C(═O)NR′—, wherein R′ us selected from H, or C 1 -C 6 alkyl;
wherein L′ is a linking motif independently selected from linear or branched, saturated or unsaturated, substituted or unsubstituted C 1 to C 18 alkyl;
wherein ‘Si′’ is a polysiloxane.

5 . A consumer goods product according to claim 1 , wherein the functionalised lignin oligomer is non-cross linked and comprises a functional group being linked via one of the following structural features:
(R 1 )(R 1 ′)C═C(R 2 )—N(R 3 )(R 3 ′)
wherein R 1 , R 1 ′ and R 2 are independently selected from hydrogen or lignin backbone, wherein at least one of R 1 , R 1 ′ and R 2 is lignin backbone, wherein R 3 and R 3 ′ are both independently selected from saturated or unsaturated, linear or branched, substituted or unsubstituted C 1 -C 32 alkyl, wherein at least one of R 3 or R 3 ′ is bound to the ‘Si’ polysiloxane;
