METHYLPENTENYLCYCLOHEXENE CARBALDEHYDE

Description

Methylpentenylcyclohexene carbaldehyde, also known as Lyral or Kovanol, is a synthetic fragrance ingredient commonly used in skincare and personal care products. This colorless to pale yellow liquid has a floral, woody aroma reminiscent of lily of the valley. Its molecular structure allows for slow evaporation, providing a long-lasting scent in formulations.

In skincare, this compound is primarily utilized for its olfactory properties, enhancing the overall sensory experience of products. It is often found in moisturizers, serums, and facial cleansers. While not directly contributing to skin health, its pleasant scent can improve user compliance with skincare routines.

However, methylpentenylcyclohexene carbaldehyde has been associated with contact allergies in some individuals. The European Union has restricted its use in cosmetics due to its potential sensitizing effects. Formulators must adhere to concentration limits and consider alternative fragrance options for sensitive skin formulations.

When incorporating this ingredient, it's crucial to balance its aromatic benefits with potential risks. Product labels should clearly disclose its presence to allow consumers with known sensitivities to make informed choices.
