MICHELIA ALBA FLOWER OIL.

Questionable CAS 92457-18-6 / FRAGRANCE

Michelia Alba Flower Oil, derived from the White Champaca flower, is an essential oil recognized for its aromatic qualities and potential dermatological benefits. It exhibits properties that can reduce melanin synthesis and provide antioxidant protection, while also nourishing dry skin. However, its composition necessitates careful consideration due to potential for skin irritation and sensitization.

Summary

Melanin Reduction Tyrosinase Inhibitor Antioxidant Anti-inflammatory Antimicrobial Skin Nourishing Perfuming Masking

Science

Mechanism of Action

Michelia Alba Flower Oil primarily functions on the skin by inhibiting tyrosinase activity, thereby reducing melanin production and contributing to a more even skin tone. Key components like α-terpineol demonstrate significant antioxidant effects, reducing cellular oxidative stress indicators such as malondialdehyde and boosting natural antioxidant levels like GSH. Additionally, the oil possesses anti-inflammatory and antimicrobial attributes, which support overall skin health and soothing, while also nourishing and softening dry or mature skin.

Key findings

  1. 01 A compound identified in M. alba, (-)-N-formylanonaine, demonstrated inhibition of human tyrosinase activity and a reduction in melanin content within epidermal melanocytes, achieving an EC50 of 90 µM for melanin reduction.
  2. 02 α-terpineol, a significant component of M. alba flower oil, reduced melanin content and tyrosinase activity in B16 cells stimulated with α-melanocyte-stimulating hormone (α-MSH) at concentrations ranging from 100-200 µM, without compromising cell viability. This compound also mitigated oxidative stress by decreasing cellular malondialdehyde and increasing cellular GSH levels.

Stability

Esters naturally present in the essential oil can undergo hydrolysis, forming their corresponding acids, which may impact product stability over time. The presence of Methyl Eugenol can also lead to undesired coloration shifts within formulations. It is chemically stable, but strong oxidizing agents should be strictly avoided to preserve its integrity.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

While generally recognized as safe (GRAS) by FEMA for flavoring purposes, Michelia Alba Flower Oil has not been reviewed by the Cosmetic Ingredient Review (CIR) panel for topical cosmetic safety. Safety Data Sheets classify this ingredient as 'Skin Irritation - Category 2' and 'Skin Sensitization - Category 1', indicating it can cause irritation and may provoke an allergic skin reaction. Linalool, a major constituent comprising up to 90% of the oil, is a well-documented skin sensitizer.

Our Assessment

Verdict

Questionable

Despite offering promising melanin-reducing and antioxidant properties, the high risk of skin irritation and sensitization, largely attributable to its significant Linalool content, renders Michelia Alba Flower Oil a questionable ingredient for precision skincare formulations without extremely careful consideration and formulation at minimal concentrations.
