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.

Abstract: A novel admixture for mineral binders is composed of a polyol composition with a high hydrogenated disaccharide content (≧40%). The hydrogenated disaccharide is advantageously chosen from maltitol, lactitol and mixtures thereof. Within the admixture, the polyol composition (for example, maltitol powder, a maltitol syrup or a hydrogenated starch hydrolysate) may be combined with conventional admixtures for mineral binders, particularly lignosulfonates. The hydrogenated disaccharides make it possible to obtain an excellent compromise between retardation, plasticity and the mechanical properties of the mineral binder. They may be used equally well for admixing with cements and raw materials for cements as for admixing with mortars, slurries and concretes.

Abstract: A method for extracting minor fatty compounds, particularly steroids, from biological matter by means of cyclodextrin. According to the method, the cyclodextrin is stirred into said biological matter in a water-containing reaction medium to allow the formation of inclusion complexes between the cyclodextrin and the minor fatty compounds, whereafter said complexes are separated from said matter, the amount of water present in the reaction medium being lower than 100 % wt. in relation to the matter to be treated. The temperature of the reaction medium and the amount of water present therein are such that the cyclodextrin is partially undissolved.
