MICHELIA ALBA LEAF OIL.

Questionable CAS 92457-18-6 / FRAGRANCE

Michelia Alba Leaf Oil is an aromatic botanical extract recognized for its potential skin benefits, including brightening and soothing properties, though its primary role in formulations often leans towards fragrance. Its efficacy in precision skincare is balanced against significant safety considerations.

Stability

The essential oil's stability can be compromised by ester hydrolysis, leading to acid formation. Methyleugenol content may also cause coloration issues. For optimal stability, essential oils rich in linalool should be formulated with minimal peroxide levels, and the inclusion of antioxidants like 0.1% BHT or α-tocopherol during production is advised.

While generally recognized as safe (GRAS) by FEMA for food use, Michelia Alba Leaf Oil poses a significant risk for skin irritation (Category 2) and sensitization (Category 1), with product safety data sheets recommending a skin test prior to use. Key components like methyleugenol have stringent maximum concentration recommendations: SCCNFP (predecessor to SCCS) suggests a maximum of 0.0002% in leave-on products, and IFRA recommends 0.0004%. Oxidation products of linalool, another major component, are also noted as potential skin sensitizers.

Verdict

Questionable

Despite promising in-vitro data for skin brightening and anti-inflammatory effects from its isolated compounds, the high risk of skin irritation and sensitization, coupled with very strict concentration limits for a known sensitizing component, renders Michelia Alba Leaf Oil a questionable ingredient for precision skincare formulations.
