1,3-DIMETHYL-BICYCLOHEPTANE-2-CARBONITRILE.

The Cosmetic Ingredient Review (CIR) has classified this ingredient with 'insufficient data' for a full safety assessment. While The Good Scents Company reports no GHS classification or hazard statements found for 1,3-DIMETHYL-BICYCLOHEPTANE-2-CARBONITRILE, this may indicate a lack of specific cosmetic assessment rather than confirmed safety. Closely related compounds, such as Bicyclo[2.2.1]heptane-2-carbonitrile (unsubstituted), are classified as hazardous, causing skin irritation, serious eye irritation, and respiratory irritation (GHS Categories 2), and are harmful if swallowed, inhaled, or in contact with skin (Acute Toxicity Category 4). Another related compound, Bicyclo(2.2.1)heptane-2-carboxylic acid, 3,3-dimethyl-, is also known to cause skin irritation (H315). The EPA's Substance Registry Services lists this substance, and the New Zealand EPA notes it 'Does not have an individual approval but may be used under an appropriate group standard'. These findings necessitate a cautious approach due to the potential for irritation based on structural similarities.
