Octyl methoxycinnamate

0Octyl methoxycinnamate (also known as OMC, octinoxate, or ethylhexyl methoxycinnamate) is an organic compound that is commonly used in sunscreen products. It is an ester formed from methoxycinnamic acid and 2-ethylhexanol. It is a clear liquid that is insoluble in water.

Chemical Properties

Octyl methoxycinnamate is a clear, colorless to pale yellow liquid that is not soluble in water. It has a slightly floral odor. Its chemical formula is C18H26O3, and its molecular weight is 290.40 g/mol. It has a boiling point of 198-200°C and a melting point of -25°C.

Uses

The primary use of octyl methoxycinnamate is in sunscreens and other cosmetics to absorb UV-B rays from the sun, protecting the skin from damage. It is also used in hair products to prevent color degradation from the sun. In addition to its UV-absorbing properties, it also has emollient and moisturizing properties, which make it a popular ingredient in skincare products.

Safety and Health Effects

While octyl methoxycinnamate is generally considered safe for use in cosmetics, there have been some concerns about its potential effects on human health. Some studies have suggested that it may have estrogenic effects, which could potentially increase the risk of breast cancer. However, these findings are not conclusive, and more research is needed to fully understand the potential health effects of octyl methoxycinnamate.

Regulation

In the United States, octyl methoxycinnamate is regulated by the Food and Drug Administration (FDA). It is approved for use in sunscreens at concentrations up to 7.5%. In the European Union, it is approved for use at concentrations up to 10%.
