CITRUS AURANTIUM LEAF OIL.

Valuable CAS 72968-50-4 / PERFUMING

Commonly known as Petitgrain, this essential oil is steam-distilled from the leaves and twigs of the bitter orange tree. It serves as a multifunctional botanical agent that balances sebum production while providing significant antioxidant protection against environmental stressors.

Summary

Antioxidant Astringent Antimicrobial Sebum Regulator Fragrance

Science

Mechanism of Action

Petitgrain oil functions through a multi-pathway approach: it inhibits elastase and collagenase enzymes to preserve the skin's structural integrity, utilizes high concentrations of linalool and linalyl acetate for microbial control, and provides a rich profile of antioxidants (including a FRAP value of 200.43 mg TE/g) to neutralize free radicals. Additionally, its astringent properties help refine pore appearance and regulate lipid synthesis.

Key findings

  1. 01 In vitro analysis published in MDPI demonstrated that Citrus aurantium leaf extract significantly inhibits enzymes responsible for collagen and elastin degradation, confirming anti-aging efficacy.
  2. 02 Comparative distillation studies recorded robust antioxidant capacities across various metrics, including ABTS and DPPH assays, highlighting its role in oxidative stress prevention.

Stability

Prone to oxidation; the formation of hydroperoxides from limonene and linalool can increase sensitizing potential. Inclusion of secondary antioxidants like Tocopherol is recommended to maintain stability.

Sensitization risk Moderate

The CIR Expert Panel considers it safe up to 8% in non-sensitizing formulations. However, because it contains naturally occurring allergens like linalool and limonene, EU regulations strictly limit furocoumarin content to 1 mg/kg to prevent phototoxicity.
