The present invention relates to oligoesters and their use or the creation of additives. Oligoester containing additives and/or oligoesters themselves may be used for formulating pharmaceutical preparations, cosmetics or personal care products such as shampoos and conditioners. These oligoesters are particularly useful for the creation of multi-purpose additives that can impart conditioning, long substantivity and/or UV protection. Individual oligoesters and oligoester mixtures are described.

Self-assembled gel compositions including a gelator, e.g., an enzyme-cleavable gelator, e.g., having a molecular weight of 2500 or less, are described. The self-assembled gel compositions can encapsulate one or more agents. Methods of making the self-assembled gel compositions, and methods of drug delivery using the self-assembled gel compositions are also described.
of sucrose fatty acid esters to undergo intramolecular migrations in organic medium and the regioselectivity of some transesterifications of sucrose were investigated by HPLC, in situ NMR spectroscopy and preparative methods. Extensive acylation on secondary positions of the glucose moiety followed by migrations is general for base catalysed transesterification. The stability of 3‐ and 6‐O‐acyl derivatives
