A composition (C1) comprising, per 100% of mass:
- (1)—an amount of greater than 0% by mass and less than or equal to 25% by mass of a polyol of formula (I):
- HO—CH2—(CHOH)m—CH2—OH (I);
- in which formula (I) m represents an integer equal to 2, 3 or 4;
- (2)—an amount of greater than 0% by mass and less than or equal to 30% by mass of one or more anhydrides of said polyol of formula (I);
- (3)—from 60% by mass to 95% by mass of a composition (CR) represented by formula (II):
- HO—CH2—(CHOH)m—CH2—O-(Rham)X—H (II),
- in which formula (II) Rham represents a rhamnose residue, m is as defined in formula (I) and x, which indicates the average degree of polymerization of said Rham residue, represents a decimal number greater than 1.0 and less than or equal to 2.5;
- and
- (4)—an amount of greater than 0% by mass and less than or equal to 5% by mass of rhamnose.
