D-Limonene is a cyclic monoterpene and a major component of citrus oils. It is widely used as a non-polar solvent, especially in applications requiring the dissolution of thermoplastics such as HIPS (High Impact Polystyrene) and ABS. It is valued for its low toxicity, biodegradability, and pleasant odor.
