Antifoaming compositions and intermediate anhydrous compositions

A process for the preparation of a composition (D), comprising:

• mixing a sugar of formula (V):
• H-G-OH (V)
• in acidic medium with an excess of at least one alcohol of formula (VI):
• HO—RA (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)x—O—RA (III),
• mixing said reaction mixture with a compound of the following formula (IV):
• HO—[CH2—CH(R1)—O]n—RB (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)x—O—RA (III)
• and (b) at least one compound of the formula (IV):
• HO—[CH2—CH(R1)—O]n—RB (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.
