Abstract: The present invention is relative to the use of a composition comprising at least one mineral filler having properties of absorption and/or emission in the far infrared region ranging from wavelength of 2 micrometers to 20 micrometers dispersed in a marine biodegradable polymeric composition for improving marine biodegradability of said marine biodegradable polymeric composition.

Abstract: A process for preparing spherical polymeric particles of polymers containing at least two fillers, dispersed in the polymer matrix wherein up to 50% of the weight of the particles is composed by fillers. The process comprises a melt-blending of a polymeric matrix containing the at least two fillers with a continuous phase that is not miscible with the polymeric matrix and an agent to form an emulsion. This emulsion is then extruded, cooled and a solvent of the continuous phase is added to recover the spherical particles. The fillers can provide different properties to the spherical particles which can be used, for example, for cosmetic applications, specifically for preventing and/or reducing the signs of skin ageing.

Abstract: A process for the production of dioxolane compounds of formula (I): wherein R1 and R2 independently represent hydrogen or an alkyl chain from 1 to 10 carbon atoms; R3 and R4 independently represent hydrogen, an alkyl chain from 1 to 5 carbon atoms, or an alkyl chain from 1 to 5 carbon atoms which is endowed with one or more hydroxyl groups, such process comprising a reaction between crude glycerol and an aldehyde or a ketone, with a molar ratio of aldehyde:glycerol or ketone:glycerol from 3:1 to 20:1.

Abstract: A process for the production of dioxolane compounds of formula (I), wherein R1 and R2 independently represent hydrogen or an alkyl chain from 1 to 10 carbon atoms; R3 and R4 independently represent hydrogen, an alkyl chain from 1 to 5 carbon atoms or an alkyl chain from 1 to 5 carbon atoms endowed with one or more hydroxyl groups. Such process comprises successively a reaction step between crude glycerol and aldehyde or ketone and a liquid-liquid extraction step with an extracting ketonic solvent corresponding to formula (II) with A and B independently being an alkyl chain with 2 to 10 carbon atoms, or phenyl, A and B not comprising hydroxyl functions.

Abstract: A method for preparing di-alpha-methyl benzyl adipate by direct esterification of adipic acid and alpha-methylbenzyl alcohol is described. The reaction can produce a high yield and can be carried out under mild conditions, in the presence of a catalyst selected from among the orthotitanates of tetra-hydrocarbyl.
