Use of a compound of the general formula (I) R1 - C(O)- O - R2 wherein R1 is a straight chain C3-23 alkyl group, a straight chain C3-23 alkenyl group, a straight chain C5-23 alkadienyl group, or a straight chain C7-23 alkatrienyl group, where the alkyl, alkenyl, alkadienyl and alkatrienyl group may optionally be substituted with 1 or 2 OH groups; R2 is a straight chain C1-10 alkyl group which may optionally be substituted with 1 or 2 OH groups; with the proviso that the total number p of carbon atoms in R1 and R2 is in the range of 12 « p « 26; or a mixture of such compounds in the clarification and/or deparaffination procedures in the processing of histological tissue samples. R2 is preferably a C1-6 alkyl group, in particular a C1-4 alkyl group, and p is preferably in the range 12 « p « 18. Specific examples of formula (I) is n-butyl decanoate and n-butyl dodecanoate. In the use according to the invention, the compound (I) may be used in combination with other components such as saturated hydrocarbon solvents, vegetable oils, other esters of mono-, di- or tricarboxyl acids, or terpenes. |
