| Résumé : |
In 1973, a new fungicide for the preservation of chrome stock was described at the Thirteenth Congress of the IULTCS in Vienna. The material, n-octyl-4-isothiasol-3-one, known commercially as Kathon LP, has been in use for six years worldwide with a very high level of acceptance include its broad spectrum of activity against fungi, its cost effectiveness relative to other commercially available products, and its complete inactivation in the effluent stream.
For many years p-nitro phenol has been specified as the preservative for military leathers and has beensuccessfully utilized in this application. Nevertheless, alternatives p-nitro phenol are desirable, and it was our feeling that n-octyl-4-isothiazol-3-one is a likely candidate. To qualify, however, there are several requirements. Among these are a suitable spectrum of activity, sufficient field experience to request EPA registration for this use, an analytical procedure to determine levels in submitted leathers, and evidence that the treated leathers will pass the stringent military tests conducted at the Natick R&D Command.
The first requirement is easily met, as indicated in Table 1. The purpose of this paper is to show how the other requirements are met : field experience, the state of the analytical procedure, and the laboratory test results. |
