Amyl Cinnamal Worst Fragrance Synthetic and Natural No known benefits Amyl Cinnamal at a glance Volatile fragrance ingredient with a jasmine-like aroma Occurs naturally in some plants, but the ingredient used in products is typically synthetic Proven to frequently cause skin reactions Even if you don’t see or feel the negative effects on skin, long term damage occurrs under the surface Amyl Cinnamal description Amyl cinnamal is a volatile fragrance ingredient with a jasmine-like aroma. Although this ingredient occurs naturally in some plants, the form included in personal care products is usually created synthetically. Research data spanning decades has shown fragrance ingredients are one of the main causes of skin sensitization and amyl cinnamal is no exception. In fact, due to its long history of causing skin reactions amyl cinnamal has been used in dermatitis patch testing to detect allergenicity toward fragrance. Daily use of products that contain a high amount of fragrance, whether the fragrant ingredients are synthetic or natural, causes a chronic sensitizing reaction on skin. This reaction in turn leads to all kinds of problems, including disrupting skin’s barrier, worsening dryness, increasing or triggering redness, depleting vital substances in skin’s surface, and generally preventing skin from looking healthy, smooth, and hydrated. A surprising fact: Even though you can’t always see or feel the negative effects of fragrant ingredients on skin, the damage still takes place under the surface. Research has demonstrated that you don’t need to see or feel the effects of irritation for your skin to be suffering. Much like the effects from cumulative sun damage, the negative impact and the visible damage from fragrance may not become apparent for a long time. According to the International Fragrance Association, the maximum concentrations of amyl cinnamal in personal care products should not exceed the following: 0.063% for products applied to the lips (lipstick, etc.) 0.38% for products applied to the face/body using fingertips (more likely rinse-off) 0.089% for lotions applied to face/body using the palms of your hands (primarily leave-on) While amyl cinnamal is the recognized INCI (International Nomenclature Cosmetic Ingredient) name, it may also be listed as other names in your personal care products including alpha-amyl cinnamic aldehyde, amylcinnamic aldehyde, amylcinnamal, and amylcinnamaldehyde.
