Gamma Poly glutamic acid (novel molecule that is a component of the mucilage of the fermented soybean food product commonly found in Japan called natto.
The International Nomenclature Cosmetic Ingredient (INCI) name of'y-PGA is nattogum and it is classified as a film-forming agent.
The sodium salt of gamma-PGA, which is more commonly used and thus served as the test sample in this paper, displays the visual appearance of a sticky paste.The fermented soybean mucilage consists of a mixture of gamma-PGA and fructan produced by Bacillus natto. Further research by Bovarnick revealed gamma-PGA to be a fermentation by-product freely secreted into growth nedium outside of the cell walls of Bacillus subtilis. This discovery advanced collateral investigations to determine whether this bacteriological process could be reproduced in other
species of Bacillits.
