Safety

Skin sensitization if oxidized

Oxidation products of (+)-limonene and α-pinene may sensitize skin.

Store in dark, sealed, refrigerated container. Add an antioxidant.

Non-phototoxic.

Initial 20 percent test produced 2 of 25 sensitization reactions, but the sample had oxidized. A second test using nitrogen-protected, BHA-stabilized oil produced no sensitization. This underscores the importance of storage.
