Abstract：
:Natural and synthetic chemicals are often used in the fragrance industry. A toxicological profile of the synthetic fragrance booster, 4-cycloocten-1-carbaldehyde, was generated using a test program including the following methods: acute oral toxicity, acute dermal toxicity, acute skin and eye irritation, skin sensitization, subchronic toxicity, and mutagenicity. The substance was strongly irritating to the skin but only weakly irritating to the eye. It gave a clear indication of having skin-sensitizing properties. Based on the comprehensive data from a mutagenicity test battery, 4-cycloocten-1-carbaldehyde was assessed to be nonmutagenic. Although its acute toxicological profile shows no toxicity after oral or dermal application, 4-cycloocten-1-carbaldehyde displays a complex toxicological response after repeated dosing over 13 weeks. 4-Cycloocten-1-carbaldehyde or its metabolites show clear nephrotoxic properties focusing on tubular cells of the kidney. In view of these data no no-effect level can be derived from this study with 4-cycloocten-1-carbaldehyde. A broad interaction of the test substance with various tissue types and cell parameters together with severe and irreversible organic defects even at low doses leads to the conclusion that 4-cycloocten-1-carbaldehyde is unsuitable for the intended use in industrial fragrance formulations.
