Quince seed mucilage

Other properties which are of commercial value but are peculiar to more limited groups are as follows (a) the ability of cellulose derivatives, particularly carboxymethylcellulose to adsorb onto cotton libers, forming a barrier repellent to dirt and (b) the ability of carrageenans and quince-seed mucilage to alter the aggregation of casein in milk. The last two poly-sacolloids are the only ones that seem to be absorbed by skin tissues, making them particularly effective in cosmetic and pharmaceutical preparations for topical application.

Both psyllium and quince seeds are imported into the United States for limited, specialized uses. Almost all the psyllium seed arriving from India proceeds to pharmaceutical houses for use in laxative preparations utilizing the mucilage-containing seed husk. Quince seeds from Iran are purchased by cosmetics houses, principally for use in hand-lotions. Each user prepares his own mucilage extract directly from the seeds, as needed. Seed supplies are restricted, so that any unusual demand is reflected in increases in price. 

Closely related to plant gums are those mucilages discussed later which are the complex acid polysaccharides extractable from endosperms of seeds of such plants as flax, quince and lucerne (see below). The acid nature of these mucilages is due to the presence of D-galacturonic acid residues in the complex molecule. ...
