Beschreibung
Zusammenfassung:	The present invention relates to an emulsifier comprising a wetting agent and a product produced by the Diels-Alder reaction of dienophiles selected from the group consisting of carboxylic acids, polycarboxylic acids, and acid anhydrides, and combinations or mixes thereof, with a mixture of fatty acids and resin acids derived from the distillation of crude tall oil, wherein said mixture comprises a ratio of fatty acids to resin acids ranging from about 4:1 to about 1:1, and wherein the ratio of said wetting agent to said product ranges from about 1:5 to about 1:1.
