Science
Mechanism of Action
As a synthetic polycyclic methoxy-aldehyde, Scentenal functions exclusively as a perfuming agent within skincare products. Its specific molecular engineering allows for robust diffusion and stability, delivering a complex aroma characterized by marine freshness, a watery-floral nuance, and crisp, ozonic facets to cosmetic formulations.
Research
Clinical Evidence
High confidence0.27%
Key findings
- 01 Clinical applications show that Scentenal provides a fresh marine-green aldehydic note in fine fragrances at concentrations between 0.005% and 0.5%. For body care products, fragrance is achieved within a range of 0.002% to 0.08%. For leave-on body/face/hand creams, the International Fragrance Association (IFRA) recommends a maximum usage level of 0.27% to balance desired scent impact with safety considerations.

Formulation
Stability
This ingredient exhibits notable stability, particularly under alkaline and oxidative conditions, rendering it effective in challenging fragrance formulations. It maintains general stability across various media and functional bases and does not cause discoloration in products such as soap.
Conflicts
- Prolonged contact with highly porous materials may result in spontaneous combustion, which is a critical handling and storage safety consideration.
Safety
Safety Profile
Scentenal is permitted under the EU Cosmetics Regulation (EC 1223/2009) and is listed as 'Not restricted' by IFRA (Amendment 51). However, IFRA imposes specific maximum usage levels across different product categories due to potential dermal sensitization and systemic toxicity. For precision skincare, maximums include 0.27% for leave-on body/face/hand creams, 0.057% for axillae products, and 0.091% for baby creams. It is classified as a Skin Sensitizer (Category 1), indicating its capacity to cause an allergic skin reaction (H317), and is recognized as a mild skin and Eye Irritant (Category 2).
