ISOAMYL P-METHOXYCINNAMATE

Description

Isoamyl p-methoxycinnamate is a potent UV filter widely used in sunscreen formulations and other cosmetic products. This organic compound belongs to the class of cinnamates and is particularly effective in absorbing UVB radiation, which is responsible for sunburn and DNA damage in skin cells. Its chemical structure allows it to efficiently convert harmful UV rays into harmless heat energy, providing significant protection against sun-induced skin damage.

The ingredient demonstrates excellent photostability, maintaining its protective properties even after prolonged sun exposure. It is oil-soluble, making it compatible with a wide range of cosmetic formulations, especially those designed for oily or combination skin types. Isoamyl p-methoxycinnamate typically appears as a clear, colorless to pale yellow liquid with a faint characteristic odor.

In sunscreen formulations, it is often used in concentrations ranging from 1% to 10%, depending on the desired SPF level and regulatory requirements in different regions. This ingredient synergizes well with other UV filters, enhancing overall sun protection when used in combination products. While generally considered safe for topical use, some individuals may experience sensitivity, necessitating patch testing before widespread application.
