Abstract: The present invention relates to a process for washing a polysaccharide-based material which has been subjected to oxidation by at least one oxidizing agent, the said process comprising a first stage of washing with a first densified fluid which is inert with regard to the said oxidizing agent, characterized in that the first stage is followed by a second stage of washing with a washing composition comprising at least one second inert densified fluid and at least one alcohol. The said process according to the invention can additionally comprise a third stage of washing with a third inert densified fluid in order to remove the said alcohol deposited on the said polysaccharide-based material during the said second washing stage. Preferably, the said inert densified fluids are supercritical carbon dioxide.

Abstract: An emulsifying composition, characterised in that it contains by weight, excluding impurities, (i) 1 to 98% by weight of a mixture of alkyl glycosides R1O(G1)g1(G2)g2(G3)g3(G4)g4(G5)g5, (ii) 1 to 90% by weight of a mixture of alcohol esters R2OZ, (iii) 1 to 90% of an alcohol R3OH, and (iv) 4 to 90% of a mixture of alkyl glycoside esters R4O(X1)x1(Z)z1(X2)x2(Z)z2(X3)x3(Z)z3(X4)x4(Z)z4(X5)x5(Z)z5, is disclosed In accordance with the composition, R1 is a hydrocarbon radical, linear or branched, saturated or unsaturated, having 10 to 22 carbon atoms. G1, G2, G3, G4, G5 are identical or different residues of -oses selected from glucose, galactose, mannose, fructose, ribose, xylose and arabinose, g1, g2, g3, g4 and g5 being equal to 0 or 1, the sum of g1, g2, g3, g4 and g5 being at least equal to 1. The composition has emulsifying capacity in the presence of electrolytes or in the case of paraffin-based emulsions.
