Abstract:
A composition comprising:a) at least one cyclodextrin monomer selected from the group consisting of &agr;-cyclodextrin, &bgr;-cyclodextrin and &ggr;-cyclodextrin; and b) at least one of biotin or a biotin ester, and wherein the molar ratio of a) to b) is chosen from one of the following: 1 mol of &agr;-cyclodextrin monomer:1 mol of biotin and/or biotin ester; 1 mol of &bgr;-cyclodextrin monomer:1 mol of biotin and/or biotin ester; 1 mol of &ggr;-cyclodextrin monomer:1 mol of biotin and/or biotin ester; 1 mol of &agr;-cyclodextrin monomer:2 mol of biotin and/or biotin ester; 1 mol of &bgr;-cyclodextrin monomer:2 mol of biotin and/or biotin ester; 1 mol of &ggr;-cyclodextrin monomer:2 mol of biotin and/or biotin ester; 2 mol of &agr;-cyclodextrin monomer:1 mol of biotin and/or biotin ester; and 2 mol of &bgr;-cyclodextrin monomer 1 mol of biotin and/or biotin ester.
