The invention concerns the use, in dry form, of a combination of substantially amorphous microfibrils with a crystallinity index not more than 50%, with at least a polyhydroxylated compound, as additive for food formulations, the content of this combination being more than 0% and less than 20% by weight relative to the total weight of the food formulation.

Use of cellulose microfibrils in dry form in food formulations

Chemically modified succinoglycan polysaccharides, e.g., acidic or enzymatic hydrolysates, have a reduced content of pyruvic acid and succinic acid structural units relative to the unmodified such succinoglycans, and are well suited, whether in fibrous, powdery or gel state, for use, e.g., as thickening stabilizing or suspending agents, in foodstuff, cosmetic and a variety of other compositions.

Chemically modified succinoglycans and industrial compositions comprised

Precipitate-free aqueous compositions, well adapted as agricultural chemicals, e.g., crop protectants, are comprised of at least one water soluble cationic organic compound, e.g., a pesticidally active quaternary ammonium compound, and a thickening amount of a xanthan gum having an intrinsic viscosity of less than 3,500 cm.sup.3 /g.

Cationic compound/xanthan gum aqueous compositions

Mixed polysaccharide compositions, well adopted for flocculating/precipitating solid particulates from liquid dispersions thereof and for the shaping of insulating articles therefrom, comprise (i) at least one succinoglycan polysaccharide, the basic recurring structural unit of which comprising glucose, galactose and succinyl moieties, and (ii) at least one natural polysaccharide or derivative thereof.

Mixed polysaccharide precipitating agents and insulating articles shaped

Physically/mechanically improved insulating shaped articles such as panels or plates, adapted to withstand very elevated temperatures, comprise an inorganic fiber matrix, e.g., a matrix of ceramic fibers, such inorganic fiber matrix containing at least one inorganic filler material, e.g., a mineral wool and/or kaolin, and a consolidating of a binder therefor which comprises admixture of a xanthan gum and a cationic starch.

Insulating shaped articles comprising inorganic fibrous matrices and

Mixed polysaccharide compositions, well adopted for flocculating/precipitating solid particulates from liquid dispersions thereof and for the shaping of insulating articles therefrom, comprise (i) at least one polysaccharide prepared by microbial fermentation, the basic recurring structural unit of which comprising both glucose and rhamnose moieties, and (ii) at least one cationic natural polysaccharide or derivative thereof.

Stable suspensions of zeolite particulates, in water, well adapted for detergency applications, include an effective stabilizing amount of a succinoglycan and, advantageously, a dispersing agent, e.g., a silicone resin or a siliconate and/or siliconate derivative.

Stable zeolite/succinoglycan suspensions

Monolithic catalyst substrates are more adherently coated with at least one oxide layer, by including in the coating composition a gum or biogum, preferably xanthan gum.
