| Comments |
d-Limonene is a liquid with a pleasant lemon-like odor. It is used as a solvent to replace chlorinated hydrocarbons and other more volatile and toxic organic solvents. It readily oxidizes when in contact with air. The oxidized form of d-limonene is a known skin sensitizer. [HSDB] The racemic mixture of d-limonene and l-limonene is called dipentene (138-86-3). [Kanerva, p. 1147] A skin and eye irritant that may cause skin sensitization; [ICSC] |
