Stability
Ethyl Phenethyl Acetal, characteristic of acetals, demonstrates robust stability under neutral to basic pH conditions, specifically above 6.5. A study on a similar acetal molecule indicated no measurable hydrolysis at pH 7.4 over a 7-day period. However, it undergoes rapid hydrolysis in acidic environments, breaking down into its corresponding carbonyl compounds and alcohol. It maintains good compatibility and stability when formulated with alcohol, alkalis, and ammonia.

Safety
Safety Profile
While not formally reviewed by the Cosmetic Ingredient Review (CIR), the Research Institute for Fragrance Materials (RIFM) has assessed the safety of its synonym, Acetaldehyde ethyl phenylethyl acetal. This assessment concluded that the ingredient can be safely used in everyday products at current exposure levels. The International Fragrance Association (IFRA) recommends a maximum usage level of 5.0% of the formula for this ingredient in fragrance applications.
