Title:
ANTI-BACTERIAL COMPOSITION CONTAINING LOW-MOLECULAR WEIGHT WATER-SOLUBLE Β-CHITOSAN OR DERIVATIVE THEREOF AS ACTIVE INGREDIENT
Document Type and Number:
WIPO Patent Application WO/2014/168281
Kind Code:
A1
Abstract:
The present invention relates to an anti-bacterial composition containing as an active ingredient a low-molecular weight water-soluble β-chitosan or a derivatives thereof, the anti-bacterial composition according to the present invention containing, as an active ingredient, a low-molecular weight water-soluble β-chitosan or a derivatives thereof derived from a natural substance and having a low molecular weight of 500-20,000 daltons, and thus the anti-bacterial composition is rapidly absorbed in the body, does not form antibodies, and is safe for the body as cell toxicity is markedly low. Furthermore, as the present invention exhibits superb anti-bacterial effect against a variety of disease-producing bacterias, same can be useful as an anti-bacterial composition in a variety of fields requiring anti-bacterial effects, such as in food additives, germicides, antiseptic agents, cleansers, deodorizers, and functional health food.
