Rhus Succedanea Fruit Cera (Japanwachs)
As all waxes, Japan wax creates a protective layer and adds shine and lustre to the skin and hair.
Japan wax is a vegetable wax made from the berries and stems of the Rhus succedanea tree. First, a decoction is being made, then the paste is left under the sun to dry and blanch.
Japan wax is very special as it contains only 5% of fatty acid, resulting in more viscosity than other waxes. It thickens formulas, as well as it gives a nice, malleable texture to the blend.
It's been used by sumo wrestlers and geishas for centuries, to shape and maintain their hairstyle. It is frequently used nowadays in haircare products for the same reason.
