Questionable CAS 68602-86-8 / PERFUMING

Liatris Odoratissima Leaf Oil, extracted from the Deertongue plant, primarily functions as a fragrant ingredient in formulations. Beyond its aromatic qualities, it is suggested to offer skin conditioning benefits, potentially contributing to skin barrier health and possessing antioxidant and anti-inflammatory properties.

Science

Mechanism of Action

This essential oil acts as a skin conditioning agent, supporting the skin's overall health. It is theorized to aid in maintaining cutaneous lipid balance, thereby helping to preserve or restore the epidermal barrier. This 'filmogenic' mechanism may contribute to reducing trans-epidermal water loss (TEWL) and enhancing epidermal hydration. Furthermore, it is suggested to exert anti-inflammatory and antioxidant effects, which could calm irritated skin and provide protection against environmental stressors.

Stability

As an essential oil, Liatris Odoratissima Leaf Oil is susceptible to high volatility, oxidation, and chemical degradation when exposed to air and light. Advanced formulation techniques, such as nanolipidic systems, are being investigated to enhance its stability and skin delivery.

Conflicts

  • Due to its significant coumarin content, which is a known sensitizer, adherence to IFRA guidelines (e.g., maximum 2.00% in fragrance concentrates) is crucial to mitigate formulation issues and ensure safety in fragrance applications.

Safety

Safety Profile

CIR Status
Not reviewed
Max tested
2%
Sensitization risk High

The US EPA has reviewed and approved 'Oils, Liatris odoratissima' for inclusion on the TSCA Inventory. However, no specific safety assessments from CIR or SCCS are available. Deertongue absolute, derived from this plant, contains up to 25.00% coumarin and up to 2.00% dihydrocoumarin, both recognized sensitizers. The International Fragrance Association (IFRA) recommends a maximum usage level of 2.00% in fragrance concentrates due to its coumarin content. General essential oils can potentially cause mucosal irritation.

Verdict

Questionable

While offering suggested skin conditioning, antioxidant, and anti-inflammatory benefits, Liatris Odoratissima Leaf Oil presents a high sensitization risk due to its substantial coumarin content and lacks comprehensive safety assessments from CIR or SCCS.
