JAPAN WAX Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Japan wax is a tallow obtained from the fruits of the oriental sumac,
Rhus succedanea (Japan, Formosa, and Indo-China), R. vemicifera
(Japan) and R. trichocarpa (China, Indo-China, India, and Japan).
Japan wax is prepared mostly from the mesocarp by hot pressing
the immature fruit. Depending upon the method of preparation,
the commercial tallow may contain more or less of the kernel fat
which alters its melting range. Japan wax may be bleached by
exposing flakes to sunlight for some days or weeks.
The wax is unusual in that it contains glycerides of the C19-C23
dibasic acids and also has a particularly high content of tripalmitin.
The former are credited with giving Japan wax its characteristic
properties of toughness and ability to be kneaded without crumbling.
Uses of Japan wax include the manufacture of candles, wax
matches, pomades, creams, polishes, textile finishes and sizing,
and lubricant for cordage and leather dressing.
