Camphor Oil Synthetic

Camphor oil synthetic is a laboratory-grade, artificially produced version of camphor essential oil, typically a clear, colorless to pale yellow liquid with a strong, penetrating camphoraceous odor, used primarily as a mounting or clearing medium in microscopy.​

Composition and properties

It consists mainly of synthetic camphor (borneone, C₁₀H₁₆O) dissolved in a neutral solvent like toluene or xylene, with a refractive index of about 1.46–1.50, low viscosity, and volatility that allows tissues to clear without shrinkage.​

Microscopy uses

Synthetic camphor oil serves as a temporary mounting medium for fresh or wet preparations, a clearing agent before permanent mounting (e.g., with Canada balsam), or an immersion oil alternative; it renders tissues transparent by dehydrating and matching refractive indices.​

Advantages

Unlike natural camphor oil (from Cinnamomum camphora), the synthetic version is purer, more consistent, free of impurities or allergens, and safer for prolonged lab use without crystallizing or discoloring slides.​
