Isoamyl p-Methoxycinnamate (Amiloxate) is an organic compound that absorbs ultraviolet (UV) light, which is an important cause of premature aging of the skin and in the development of melanoma and other forms of skin cancer. In Europe, Isoamyl p-Methoxycinnamate is an approved UV filter, which means the ingredient can be added to sunscreen products that are designed to protect the skin from the sun. In Europe, sunscreen products are considered cosmetic products. In the United States, sunscreen products are Over-the-Counter (OTC) drugs and only certain ingredients have been approved by the Food and Drug Administration (FDA) for use in these products. In assessing sunscreen active ingredients, the FDA reviews both safety and efficacy. The safety and efficacy of Isoamyl p-Methoxycinnamate has not yet been reviewed for sunscreen use by the FDA and it cannot be used in sunscreen drug products. For cosmetics in the United States, Isoamyl p-Methoxycinnamate can be used as a UV light absorber. In this case, the ingredient serves to protect the product from deterioration by absorbing, reflecting, or scattering UV light. It is usually combined with other ingredients in sunscreen products. But unless it is combined with ingredients that absorb UVA rays, it cannot provide enough protection on its own.
