Abstract

The present invention relates to improved alditol acetal compositions, in particular 1,3-2,4-di(benzylidene) sorbitol (DBS) or one of its alkylated derivatives. The improvement in these compositions is expressed in particular in terms of flow behavior and/or thermal stability. It is obtained by combining the alditol acetal with an additive selected from tocopherols, polyols and certain of their respective derivatives. These additives may act as binding or densifying agents and/or stabilizing agents or odor maskers. The alditol acetal and additive are advantageously combined by cold mixing, followed by granulation or compaction, also cold. The compositions of the invention, for example based on DBS or the methylated derivatives of DBS, are in the form of densified or compacted powders, granules, pellets, pastilles or extrudates. They are used in particular for preparing plastic or jellified materials or additives for these types of materials.
