Dependent claims

A fibrous structure comprising papermaking fibers, and comprising a surface comprising a surface softening composition comprising a glyceride copolymer having formula (I):

wherein:
each R1, R2, R3, R4, and R5 in the glyceride copolymer is independently selected from the group consisting of an oligomeric glyceride moiety, a C1-24 alkyl, a substituted C1-24 alkyl wherein the substituent is one or more —OH moieties, a C2-24 alkenyl, or a substituted C2-24 alkenyl wherein the substituent is one or more —OH moieties;
wherein each of the following combinations of moieties may each independently be covalently linked:
R1 and R3,
R2 and R5,
R1 and an adjacent R4,
R2 and an adjacent R4,
R3 and an adjacent R4,
R5 and an adjacent R4, or
any two adjacent R4;
such that the covalently linked moieties form an alkenylene moiety;

two of G1, G2, and G3 are —CH2—, and one of G1, G2, and G3 is a direct bond;
for each individual repeat unit in the repeat unit having index n, two of G4, G5, and G6 are —CH2—, and one of G4, G5, and G6 is a direct bond, and the values G4, G5, and G6 for each individual repeat unit are independently selected from the values of G4, G5, and G6 in other repeating units;
two of G7, G8, and G9 are —C2—, and one of G7, G8, and G9 is a direct bond;
n is an integer from 3 to 250;
with the proviso for each of said second glyceride copolymers at least one of R1, R2, R3, and R5 or at least one R4 in one individual repeat unit of said repeat unit having index n, is selected from the group consisting of:
8-nonenyl;
8-decenyl;
8-undecenyl;
8-dodecenyl;
8,11-dodecadienyl;
8,11-tridecadienyl;
