Argyrol is the trade name for an antiseptic for mucous membranes which consists of compounded solutions of mild silver protein. Argyrol is synonymous with the chemical Mild Silver Protein (MSP) which is pharmaceutical grade for use in medicine and sterile processes. MSP is a molecule produced in the chemical industry in Europe, consisting of elemental silver conjugated along the helix of a denatured protein molecule derived from caseinate of strictly regulated certified livestock. Argyrol 10% is 20,000 ppm with particle sizing molecular range from <8 nm to average <14.3 nm. Argyrol is a local anti-infective most familiar for both ophthalmic and upper respiratory disinfection. Widely publicized for its value to resolve gonorrhea infections, it was known to prevent gonorrheal blindness and other pathogenic bacterial and viral infections to the eyes of newborn infants. Albert C. Barnes developed and commercialized Argyrol as treatment and prevention technology.
