Rubber seed oil is oil extracted from the seeds of rubber trees. In the latex manufacturing process, rubber seeds are not historically collected and commercialized. Recent analysis shows that rubber seed oil contained the following fatty acids:
| Fatty acid | Nomenclature | Percent |
|---|---|---|
| Palmitic | C16:0 | 10.2 % |
| Stearic | C18:0 | 8.7 % |
| Oleic | C18:1 | 24.6 % |
| Linoleic | C18:2 | 39.6 % |
| Linolenic | C18:3 | 16.3 % |
In Cambodia and other rubber manufacturing areas, rubber seeds are used to feed livestock. Although rubber seed is rich in nutrition, it also contains cyanogenic glycosides which will release prussic acid in the presence of enzymes or in slightly acidic conditions.
