Limonene, is a natural substance that is extracted from the natural oils of citric fruits and gives them their characteristic smell, it is part of the terpene group, and in particular to the limonoids, that constitute one of the most extensive families of functional foods and fitonutrients working as antioxidants.
The limonene is flammable at temperatures over 48° but it is not toxic, it is not soluble in water and has a very low density it must be kept in a well ventilated and dry place, away from direct sunlight in a closed container to avoid its oxidation.
The limonene and its derivatives are respiratory and skin irritants but there is no evidence of a carcinogenic effect or genotoxicity in humans and it is biodegradable.
In recent years it acquired a singular importance as a biodegradable solvent in the 3D printing industry as a dissolvent for supports made of PS or HIPS, it has also been used as an aromatic compound or to synthetize new compounds.
Warning: flammable, toxic and may be fatal if swallowed and enter airways, always use skin, eye and airway protection, avoid releasing to environment Very toxic to aquatic life with long-lasting effects.
Due to the high concentration of the product, it is recommended to do a solubility test before dissolving a large print to ensure the solvent will not dissolve the entire model.
If the support material is a pigmented PS or HIPS (Black, red, etc.) there is a risk for the pigments to adhere and stain the final surface.
