The seeds of the "tallow tree" yield an oil (stillingia oil) having
drying properties.
_Borneo Tallow._--The kernels of several species of _Hopea_ (or
_Dipterocarpus_), which flourish in the Malayan Archipelago, yield a fat
known locally as Tangawang fat. This fat is moulded (by means of bamboo
canes) into the form of rolls about 3 inches thick, and exported to
Europe as Borneo Tallow.
A sample tested by one of us gave the following data:--

_Kapok oil_ is produced from a tree which is extensively grown in the
East and West Indies. The Dutch have placed it on the market and the
figures given by Henriques (_Chem. Zeit._, 17, 1283) and Philippe
(_Monit. Scient._, 1902, 730), although varying somewhat, show the oil
to be similar to cotton-seed oil.
VARIOUS NEW FATS AND OILS SUGGESTED FOR SOAP-MAKING.
_Carapa_ or _Andiroba oil_, derived from the seeds of a tree (_Carapa
Guianensis_) grown in West Indies and tropical America, has been
suggested as suitable for soap-making. Deering (_Imperial Institute
Journ._, 1898, 313) gives the following figures:--

Another observer (_Rev. Chem. Ind._, 13, 116) gives the setting point of
the fatty acids as 56.4 deg. C.
_Candle-nut oil_ obtained from the seeds of a tree flourishing in India
and also the South Sea Islands.
The following figures have been published:--
