Octyl Methoxy Cinnamate (Octinoxate) is a chemical sun blocking agent that absorbs ultraviolet radiation in UVB range. One percent of Octyl Methoxy Cinnamate corresponds to a SPF of about 2.
Octyl methoxycinnamate is an oil soluble chemical sunscreen agent that absorbs UVB radiation. It does not protect against UVA. It is the most widely used UVB blocking agent in the skin care industry.
Avobenzone is an oil soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays. It is a dibenzoylmethane derivative. Avobenzone exists in the ground state as a mixture of the enol and keto forms, favoring the chelated enol. Its ability to absorb ultraviolet light over a wider range of wavelengths than many organic sunscreen agents has led to its use in many commercial preparations marketed as "broad spectrum" sunscreens. Avobenzone has an absorption maximum of 310 – 400 nm.
Octyl Salicylate, also known as 2-ethylhexyl salicylate, is a common chemical found in sunscreen and certain types of makeup with sun-blocking properties. It protects against harmful ultraviolet radiation from the sun's rays, which can cause skin cancer. Octyl salicylate absorbs UVB rays but not UVA.
