Hexyl Cinnamal

Hexyl Cinnamal Description

Hexyl cinnamal, also known as hexyl cinnamic aldehyde, is a common fragrance ingredient found in various skin care and makeup products. Its jasmine-like floral aroma can be used to mask the unpleasant odor of other ingredients in formulations.

Internationally recognized as a contact allergen, hexyl cinnamal can be sensitizing, especially for those with sensitive skin or when used in high concentrations (higher on the ingredient list indicates a greater risk of irritancy). Regulations now require hexyl cinnamal to be listed separately due to its allergy potential, unlike the past practice of grouping it under the general term “fragrance” on a cosmetic ingredient list.

Hexyl cinnamal may also be used as a preservative booster to prolong the shelf-life of formulations.

Hexyl cinnamal is found in a wide variety of products, including moisturizers, shampoos, baby products, and makeup.

Hexyl cinnamal can be naturally derived from chamomile oil, but synthetic versions are more common in cosmetics. It blends well with other fragrance components, creating a more complex and appealing scent.
