In household products

An oil pressed or distilled from lemon peel, containing mostly limonene along with smaller aromatic compounds.

Why it’s used

It supplies scent — the citrus top note common in cleaners and candles — and in some cleaning formulas contributes mild grease-cutting action from its natural solvent properties.

What the evidence says

Limonene, its major component, is a recognized skin sensitizer once it oxidizes on air exposure; the fresh oil itself is low-risk in the concentrations used for fragrance. Cold-pressed citrus oils also contain trace furocoumarins with phototoxic potential, though lemon oil's phototoxicity is well documented mainly for concentrated, undiluted skin contact rather than the trace amounts in a cleaning product.

Context

In a spray cleaner or wax melt, exposure is mainly inhalation of the scent and brief skin contact with diluted product on surfaces; the sensitization concern is most relevant to prolonged, concentrated skin contact, which household use does not typically involve.

Rumors

  1. Its oxidized limonene content causes allergic skin sensitization.
