Patent ID: 8052981

Claim:
An adjuvant formulation comprising a physiological salt solution, or an oil-in-water emulsion, or a water immiscible solid phase, and optionally an aqueous phase, and comprising, as an adjuvant, one or more disaccharide derivatives of formula: wherein (i) at least 3, but not more than N-1, of the groups R are represented by: —C(═O)—(CH 2 ) x CH 3 — groups, wherein x is between 6 and 14, and (ii) at least one, but no more than N-1, of the groups R are anionic —SO 2 —OR 1 groups, wherein R 1 is a monovalent cation, wherein N is the number of groups R of the disaccharide derivative and wherein the combined number of —C(═O)—(CH 2 ) x CH 3 groups and anionic —SO 2 —OR 1 groups does not exceed N and the remaining groups R are hydrogen.
