What is Cinnamal?

Cinnamal, also known as cinnamaldehyde, is a naturally occurring organic compound found predominantly in cinnamon bark oil. It has a distinctive spicy cinnamon aroma and gives cinnamon its characteristic smell and flavor.

It is primarily used in the fragrance industry to add a warm, spicy scent to products such as perfumes, soaps, and cosmetics. Some research suggests cinnamal can cause allergic reactions and skin sensitivities in certain individuals, particularly in concentrated forms.

When you see cinnamal on a label, it's often an indication of its role as a fragrance enhancer. For those sensitive to fragrances, it's advisable to test products containing cinnamal on a small skin patch before general use.

Commonly found in: perfumes, soaps, cosmetics, lotions, candles
