Abstract: An emollient composition comprising at least one hydrocarbon fluid in an amount of 50 to 100% by weight relative to the total weight of the composition is provided. The fluid can be obtained by a process of catalytically hydrogenating a feed comprising more than 85% by weight of oligomerized olefins, at a temperature from 115 to 195° C. and at a pressure from 30 to 70 bars. A cosmetic, dermatological or pharmaceutical composition comprising the emollient composition and uses thereof are also provided.

Abstract: The invention provides a process for preparing a fluid having a boiling point in the range of from 150 to 260° C. and comprising more than 80% by weight of isoparaffins and less than 50 ppm of aromatics, comprising the step of catalytically hydrogenating a feed comprising more than 85% by weight of oligomerized olefins, at a temperature from 115 to 195° C. and at a pressure from 30 to 70 bars. The invention also provides the fluid obtainable by the process of the invention and the use of said fluid.

Abstract: A process for the production of a hydrocarbon fluid includes the step of catalytically hydrogenating a hydrocarbon cut in presence of both a dearomatization catalyst and a dewaxing catalyst in a single slurry reactor. A hydrocarbon fluid is also disclosed as being obtainable by the process.

Abstract: The invention relates to a catalyst for hydroconversion of hydrocarbons, comprising a support made from at least one refractory oxide, at least one group VIII metal and at least one group VIB metal, characterized in further comprising at least one organic compound with at least two thiol functions separated by at least one oxygenated group of formula (I): HS—CxHyOz—SH (I), where x=1 to 20, preferably 2 to 9 and for example x=6, y=2 to 60, preferably 4 to 12 and z=1 to 10, preferably 1 to 6.
