    摘要: The invention concerns buccodental formulation characterized in that it comprises at least a thickening agent comprising cellulose nanofibrils, said cellulose nanofibrils being substantially amorphous, having a crystallinity index not more than 50%. The invention also concerns said cellulose nanofibrils as thickening agent and/or flavour enhancer in buccodental formulations.

    摘要: The invention concerns compositions containing essentially amorphous cellulose nanofibrils, carboxyl cellulose with a degree of substitution not more than o.95 as additive, and optionally at least one co-additive, the content in additive and optional co-additive being less than 30 wt. % relative to the weight of nanofibrils and additive and optional co-additive. The invention also concerns a method for preparing such compositions, consisting in adding to a substantially amorphous nanofibril suspension, the additive and optionally the co-additive(s), then in drying the suspension thus additivated. The resulting compositions are easily redispersable and preserve all their rheological properties.

    摘要: Copolymers of unsaturated fatty esters capable of being obtained by copolymerization in a mineral oil of a percentage a) of an ester of a carboxylic acid A.sub.1, of a percentage b) of an ester of a carboxylic acid A.sub.2 and a percentage c) of an ester of a carboxylic acid A.sub.3, wherein a), is between 12 and 20%, c) is between 14 and 30% and b), which is preferably 72 and 45%, is such that a)+b)+c)=100%. The copolymers in accordance with the invention are reemployed as viscosity improver in lubricating oils.
