Abstract (en)
[origin: WO0103664A1] A stable composition for the delivery of vitamin C comprises particles of vitamin C (including its pharmaceutical or cosmetic derivatives) dispersed in a solid phase of wax that is chemically inert to the vitamin C. The proportions of the jojoba esters should be chosen to provide the dry-feel to the composition that is highly desired. This will usually require at least 10 %, and most preferably at least 60 % by weight of carrier material (excluding solvent and actives) in the composition. The ingredient must be contained in at least the amount needed to be effective, which in the case of vitamin C is at least 5 % (e.g., at least 5.5 % or at least 6.0 % by weight), preferably at east 10 % by weight of the dispersion/suspension as the water-soluble material or water-dispersible material.
