Science
Mechanism of Action
This oil is believed to exert antibacterial and antifungal effects, which may aid in preventing skin infections and supporting barrier integrity. It is also suggested to possess anti-inflammatory properties that could alleviate irritation, while further benefits include potentially smoothing fine lines, augmenting moisture-binding capacity, boosting microcirculation, and assisting in the healing of old scars.

Clinical Evidence

Key findings
- 01 Silver nanoparticles derived from Polianthes tuberosa flower extract (PTAgNPs) demonstrated dose-dependent antibacterial activity against E. coli and S. aureus at an IC50 of 54.56 µg/mL, and dose-dependent toxicity (anticancer activity) against the A431 cell line. It is important to note these findings relate to nanoparticles from the extract, not the pure oil.
- 02 Inhalation of Polianthes tuberosa essential oil was effective in reducing test anxiety among students.

Formulation
Stability
The oil is insoluble in water and soluble in alcohol. It requires storage in dark, airtight containers to protect against degradation from light, heat, and oxygen. Precautionary measures against static discharges and grounding of equipment are recommended due to its flammability.
Conflicts
- Direct, undiluted application to skin
- Use in high concentrations, which may cause headaches and nerve irritation
- Application on hypersensitive, diseased, or damaged skin
- Use in children younger than 2 years old
- Unspecified incompatibilities with strong oxidizing agents
Safety
Safety Profile
The FDA lists 'TUBEROSE, OIL (POLIANTHES TUBEROSA L.)' as Generally Recognized As Safe (GRAS) as a natural extractive. However, Tisserand and Young recommend a dermal maximum of 1.2% due to a moderate risk of skin sensitization. It is advised to avoid use on hypersensitive, diseased, or damaged skin, and in children younger than 2 years. The oil naturally contains Methyl Eugenol, with a maximum concentration of 1.8%, which aligns with EU cosmetic directives. EWG Skin Deep® rates it low for cancer and allergies/immunotoxicity concerns, though no specific CIR or SCCS assessments are available.

Verdict
Polianthes Tuberosa Flower Oil serves as an optional ingredient primarily for its aromatic qualities, with some potential for moisturizing, soothing, and antimicrobial benefits, though its moderate sensitization risk and maximum concentration limit of 1.2% require precise formulation.
