This is finely ground wood (sawdust), not a sandalwood extract. Sandalwood, along with other woods (narra, bar, cam, muninga, and coral), belongs to the group of insoluble redwoods. "Insoluble" here refers not to the wood itself, but to the resin-like constituents, only a very small percentage of which are water-soluble.

Sandalwood contains between 15 and 20% santalin. Santalin is not or only very slightly soluble in water, as well as in some essential oils. In alcohol and acetic acid, however, the dye dissolves very well with a red color. Once the dye is dissolved, it can be diluted with water without forming a precipitate. In ether, santaline dissolves with a yellow color. In alkaline solutions, the hue changes to violet. To dye textiles, one prepares an alcoholic extract of sandalwood. Depending on the type of stain, dark red tones (tin salts), orange to scarlet tones (aluminum salts) or violet tones (iron salts) can be obtained
