Chemical Properties
See Currant Black (Leaves). The oil is obtained by steam distillation of the flower buds in approximately 0.75% yields.
It is a mobile, pale green liquid with a cymene-like odor.
Chemical Properties
Blackcurrant absolute (Bourgeons de cassis absolute, cassis absolute) is
obtained by solvent extraction via the concrete obtained from the dormant buds of the blackcurrant bush Ribes nigrumL. (Saxifragaceae). The buds are grown and
processed, for example, in France (Burgundy). The yield is ～3%. Black-currant
absolute is a dark green paste with the characteristic, powerful, penetrating
odor of blackcurrants. The typical “catty” note is caused by a sulfurous trace
constituent, 4-methoxy-2-methyl-2-butenethiol.
Blackcurrant absolute is used in fine fragrances and in fruity food flavors.
Uses
black currant seed oil may be an effective ingredient for enhancing the skin’s ability to develop normal barrier functions and the protective effect of the corneum layer. Black currant seed oil contains fatty, linoleic, and linolenic acids. When applied to dry skin, it may increase the skin’s own content of these previously lacking components.
