IMWITOR® 988 is a partial ester of caprylic acid and glycerol. Fatty acids and glycerol are derived from vegetable sources.

​WITEPSOL® products of series W are hard fats with hydroxyl values of 20–50. They consist of a mixture of triglycerides (65–80%), diglycerides (10–35%), and monoglycerides (1–5%). As a result of their composition, these WITEPSOL® grades have a larger gap between melting and solidification points, they are less sensitive to shock cooling (more elastic), solidify more slowly, and can be readily processed both with automatic machines and with small-scale equipment. The partial glyceride content also slows down the sedimentation of solids and promotes the absorption of less readily absorbable active compounds.

WITEPSOL® W35 has a melting point 33.5–35.5°C and a hydroxyl value of 40–50 mg KOH/g
