AR-ETHYLPHENYLBUTYRALDEHYDE.

Optional CAS 68228-11-5 / PERFUMING

A high-performance synthetic fragrance molecule engineered as a safer, more potent alternative to traditional lily-of-the-valley odorants like Lilial. It provides a sophisticated olfactory profile characterized by fresh floral, green, and watery notes without the regulatory baggage of older aromatic aldehydes.

perfuming sensory enhancement

Science

As a pure perfuming agent, this molecule does not interact biologically with skin tissues to improve health; instead, it functions by slowly releasing volatile aromatic compounds that enhance the sensory experience of a formulation. It is designed for high tenacity, maintaining a consistent scent profile through a 'bloom effect' when it comes into contact with water.

Key findings

  1. 01 AICIS Public Report LTD/1927 confirmed safety in leave-on cosmetic applications at concentrations up to 0.15%.
  2. 02 Givaudan safety assessments established a maximum safe limit of 0.21% for fine fragrance applications due to its extreme potency.

Because this molecule is roughly 20 times more powerful than standard fragrance ingredients, it is used at exceptionally low levels. 'Dusting' is not a concern here, as higher concentrations would likely be olfactively overwhelming and could exceed safety thresholds for skin sensitization.
