Beispiele für Öle, die sich von tierischem oder pflanzlichem Material ableiten, und die in der erfindungsgemäßen Zusammensetzung verwendet werden können, sind Rapsöl, Korianderöl, Sojaöl, Baumwollsamenöl, Sonnenblumenöl, Ricinusöl, Olivenöl, Erdnussöl, Maisöl, Mandelöl, Palmkernöl, Kokosnussöl, Sojaöl, Senfsamenöl, Rindertalg, Knochenöl und Fischöle. Weitere Beispiele schließen Öle ein, die sich von Weizen, Jute, Sesam, Scheabaumnuß, Arachisöl und Leinöl ableiten und können aus diesen nach im Stand der Technik bekannten Verfahren abgeleitet werden. Außerdem können Öle verwendet werden, welche aus gebrauchten Altölen, wie Frittieröl gewonnen wurden. Rapsöl, das eine Mischung von mit Glycerin partiell veresterten Fettsäuren ist, ist bevorzugt, da es in großen Mengen erhältlich ist und in einfacher Weise durch Auspressen von Rapssamen erhältlich ist. Des weiteren sind die ebenfalls weit verbreiteten Öle von Sonnenblumen und Soja sowie deren Mischungen mit Rapsöl bevorzugt.
Zur Veresterung der alkoxylierten Polyole können auch Gemische obiger Fettsäuren mit fettlöslichen, mehrwertigen Carbonsäuren eingesetzt werden.

Bevorzugt werden die mehrwertigen Carbonsäuren dabei zu untergeordneten Anteilen von bis zu 30 Mol-%, bevorzugt 1 bis 20 Mol-%, insbesondere 2 bis 10 Mol-% eingesetzt.
In einer bevorzugten Ausführungsform der Erfindung handelt es sich bei diesen Alkylphenol-Formaldehydharzen um solche, die Oligo- oder Polymere mit einer repetitiven Struktureinheit der Formel sind, worin RA für C4 bis C30-, insbesondere C6- bis C24-Alkyl oder -Alkenyl, RB für OH oder O-(A-O)x-H mit A = C2-C4-Alkylen und x = 1 bis 50, und n für eine Zahl von 2 bis 50, insbesondere 5 bis 40 und speziell 7 bis 12 steht.
