Agroforestry Uses: The seed cake residue, after the extraction of oil, is a good fertilizer[345 ]. Other Uses A high-quality, quick-drying oil is obtained from the seed[345 , 377 ]. The seeds contain 56% oil (bagilumbang oil). It is utilized for the production of paints, varnishes, soaps and for coating boats or as fuel oil[317 ]. The oil was formerly employed in the Philippines for the production of a weak soap which was in demand among sailors owing to its property of lathering in sea water[327 ]. The oil is an effective insecticide[345 ]. The oil is similar to tung oil, obtained from Aleurites spp.[377 ]. Tung oil is a very fast-dring oil with a wide range of applications, including medicinal[K ]. The oil is of best quality only when obtained from the fresh seeds, it deteriorates if not stored in hermetically sealed containers[345 ]. The shells are easily cracked and the oil obtained from the pressed, shelled seeds is of much higher quality than that obtained from crushing the seeds in their shells[345 ].
