Abstract
The invention provides a virus-inactivating composition with pH of 3.8 to 5.5, containing (A) 0.02 to 0.3 M arginine and (B) a component such as 0.01 to 10 mM flavonoid, polyphenol, or ascorbic acid derivative, 0.005 to 5 mass % of an arginine derivative, and 0.1 to 2.5 mass % of an extract solution of natural product.
Claims1
A method of inactivating lipid-envelope viruses on a virus contaminated surface in need thereof, wherein the surface is an outer surface of living tissue of humans or animals or is a surface of a substrate, and wherein said viruses are proliferating on the surface, the method comprising bringing a composition with pH of 3.8 to 5.5 into contact with the virus contaminated surface,
- wherein the composition comprises:
- (A) 0.115M to 0.287M arginine, and
- (B) a component (B) selected from the group consisting of:
- i) 0.01 to 0.5 mM of (−)epicatechin gallate or (−)epigallocatechin gallate;
- ii) 0.01 to 0.1 mM caffeic acid phenethyl ester;
- iii) 0.1 to 10 mM dehydroascorbic acid;
- and
- iv) 0.005 to 0.02 mass % of cocoyl arginine ethyl ester;
- and
- wherein said viruses are selected from the group consisting of influenza and herpes.
