Filmbildendes Mittel zum Schutz vor Infektionen

摘要

A film-building agent useful to protect against infections contains a film-building element and one or several active disinfectant substances. The film-building agent is characterised in that it contains (a) as film-building agent 10 to 100 g/l polyvinyl alcohol polymers or copolymers with a molar mass in a range from 18,000 to 200,000; (b) as active disinfectant substance 0.2 to 3 g/l iodine in the form of polyvinylpyrrolidone iodine and/or 5 to 50 g/l chlorhexidine; and (c) 2 to 50 g/l ether carboxylic acids of the general formula R-(OC2H4)n-OCH2-COOH, in which R stands for an alkyl radical with 4 to 10 C atoms and n for a number from 2 to 8. Preferably, the agent also contains thickeners and anionic or non-ionic surfactants. It is particularly suitable to protect the teats and udders of cows, ewes and goats after milking and forms a visible, mechanically resistant film.
