Abstract
A dimeric fatty acid and/or dimeric fatty ester product having a low residual content of interesters is obtained by hydrolyzing the interesters to provide monomeric unsaturated fatty acids and alcohols as the hydrolysates and thereafter removing the hydrolysates from the dimeric fatty acid and/or dimeric fatty ester product.
