Perfume and Flavor Materials of Natural Origin, page 195.
Hyacinth Absolute is usually a reddish-brown or dark brown to greenish-brown, viscous liquid.
It has an intensely sweet, green-floral, but somewhat sharp and at first unpleasant odor; later in its tremendous tenacity, it tones down to a very hyacinth-like, floral and foliage-green fragrance.
The absolute could be used in a variety of floral fragrances, provided that it were available at a reasonable cost and if it were readily available, uniform and reliable.
Extraction is performed either by the conventional two-step method via the concrete, or by the more recently developed adsorption method.
