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.

L'invention concerne un agent filmogène de protection contre les infections contenant un composant filmogène et un ou plusieurs principes actifs désinfectants. Cet agent se caractérise en ce qu'il contient (a) comme composant filmogène 10 à 100 g/l de polymères ou de copolymères de polyvinylalcool d'une masse molaire comprise entre 18000 et 200000; (b) comme principe actif désinfectant 0,2 à 3 g/l d'iode sous forme d'iode de polyvinylpyrrolidone et/ou 5 à 50 g/l de chlorhexidine; et (c) 2 à 50 g/l d'acides éthercarboxyliques de formule générale R-(OC¿2?H¿4?)¿n?-OCH¿2?-COOH, dans laquelle R désigne un radical alkyle de 4 à 10 atomes de C et n vaut 2 à 8. En outre, l'agent décrit comprend de préférence des épaississants et des agents tensioactifs anioniques ou non ioniques. Il sert notamment à protéger les tétines et les pis de vaches, de brebis et de chèvres contre des infections après la traite et forme un film visible et mécaniquement solide.
