Abstract:
A process for the preparation of a composition (D), comprising:mixing a sugar of formula (V): H-G-OHâ€ƒâ€ƒ(V) in acidic medium with an excess of at least one alcohol of formula (VI): HOâ€”RAâ€ƒâ€ƒ(VI) thereby to form a reaction mixture comprising at least one alcohol of formula (VI) and at least one compound with the following formula (III): (G)xâ€”Oâ€”RAâ€ƒâ€ƒ(III), mixing said reaction mixture with a compound of the following formula (IV): HOâ€”[CH2â€”CH(R1)â€”O]nâ€”RBâ€ƒâ€ƒ(IV), in a weight ratio of (III)/(IV) between 0.1 and 10, thereby to form a mixture comprising at least an alcohol of formula (VI), a compound of formula (III) and at least one compound of formula (IV),neutralizing said mixture, and distilling said mixture to obtain said composition (D), said (D) composition consisting essentially of: (a) at least one compound of the formula (III): (G)xâ€”Oâ€”RAâ€ƒâ€ƒ(III) and (b) at least one compound of the formula (IV): HOâ€”[CH2â€”CH(R1)â€”O]nâ€”RBâ€ƒâ€ƒ(IV) wherein x represents a decimal number between 1 and 5, n represents an integer between 1 and 30, R1 represents hydrogen or methyl, G represents the residue of a saccharide, RA and RB represent independently of one another, a saturated or unsaturated, linear or branched hydrocarbon comprising 1 to 30 carbon atoms, and said composition (D) being devoid of water and of fatty alcohols.
