- Application field
Octyl Methoxycinnamate, also called Octinoxate, is one of the safest and widely used UV B filter. Octyl Methoxycinnamate filters UV‐B rays from the sun. It does not protect against UV-A rays. Octyl Methoxycinnamate dissolves in oil, which makes it a fat-seeking substance in the body. Octyl Methoxycinnamate can easily be dispersed into oil phase of anemulsion. It is compatible with most cosmetic material and can be emulsified either hot or cold, depending upon the emulsifier. It offers absorption of UV B radiation from 290 to 320 nm. It is ideal for use in sun-care and skin-care products for everyday protection. It is suitable for the formulation of sun-protection products.
Octyl Methoxycinnamate can be used in hair color products and shampoos, sunscreen, lipstick, nail polish, skin creams. In products other than sunscreens, it is used as a UV filter to protect the products from degrading when exposed to the sun.
