Sec.  184.1097  Tannic acid.

    (a) Tannic acid (CAS Reg. No. 1401-55-4), or hydrolyzable 
gallotannin, is a complex polyphenolic organic structure that yields 
gallic acid and either glucose or quinic acid as hydrolysis products. It 
is a yellowish-white to light brown substance in the form of an 
amorphous, bulky powder, glistening scales, or spongy masses. It is also 
ordorless, or has a faint characteristic odor, and has an astringent 
taste. Tannic acid is obtained by solvent extraction of nutgalls or 
excrescences that form on the young twigs of Quercus infectoria Oliver 
and related species of Quercus. Tannic acid is also obtained by solvent 
extraction of the seed pods of Tara (Caesalpinia spinosa) or the 
nutgalls of various sumac species, including Rhus semialata, R. 
coriaria, R. galabra, and R. typhia.
