Octyl 4-methoxycinnamate CAS#5466-77-3
Octyl 4-methoxycinnamate, scientifically known as 2-Ethylhexyl 4-Methoxycinnamate, is a highly effective organic UV filter commonly used in the formulation of sunscreens and cosmetic products. This compound is renowned for its ability to absorb ultraviolet B (UVB) radiation, providing a reliable defense against the sun’s harmful effects on the skin.
Characterized by its chemical formula C19H28O3, Octyl 4-methoxycinnamate is a liquid ester that is readily soluble in organic solvents. It is valued for its photostability, which means it maintains its protective properties even after prolonged exposure to sunlight. This feature makes it an ideal ingredient for products designed to offer long-lasting sun protection.
In addition to its UVB absorption capabilities, Octyl 4-methoxycinnamate is also appreciated for its compatibility with other UV filters, allowing for the creation of broad-spectrum sunscreens. It contributes to the development of formulations that are non-greasy and cosmetically elegant, suitable for a variety of skin types.
As a key component in sun care products, Octyl 4-methoxycinnamate supports the skin’s health by preventing sunburn, reducing the risk of skin cancer, and delaying the signs of photoaging. Its safety profile and efficacy make it a preferred choice in the personal care and dermatological industries for sun protection solutions.
