Beschreibung
Zusammenfassung:	The present invention describes a composition comprising: (A) at least one polyalkyl (meth) acrylate polymer having a number average molecular weight Mn of from 15000 to 75000 g/mol; (B) at least one ethylene vinyl acetate copolymer comprising units being derived from at least one alkyl (meth) acrylate having 1 to 30 carbon atoms in the alkyl residue; (C) a phenolic type antioxidant; (D) a mixture stabilizer; and (E) a glycol ether solvent. The composition is useful as cold flow improver and oxidation stabilizer in vegetable oils and animal fats. La présente invention concerne une composition comprenant : (A) au moins un polymère poly(méth)acrylate d'alkyle de masse moléculaire moyenne en nombre Mn de 15 000 à 75 000 g/mol ; (B) au moins un copolymère éthylène acétate de vinyle comprenant des motifs dérivant d'au moins un (méth)acrylate d'alkyle comportant de 1 à 30 atomes de carbone dans le résidu alkyle ; (C) un antioxydant de type phénolique ; (D) un stabilisant de mélange ; et (E) un solvant éther de glycol. La composition est utile pour améliorer l'écoulement à froid et la stabilité à l'oxydation d'huiles végétales et de graisses animales.
