octinoxate

Description

Octinoxate, also known as ethylhexyl methoxycinnamate (EHMC), is a widely used organic compound in sunscreen formulations. This UVB filter effectively absorbs short-wave ultraviolet radiation, providing protection against sunburn and potential DNA damage. Octinoxate is oil-soluble, making it compatible with various cosmetic formulations and enhancing its ability to adhere to the skin.

The ingredient's popularity stems from its efficacy in blocking UVB rays and its stability in sunlight. Octinoxate typically comprises 2-15% of sunscreen formulations, depending on desired SPF levels and regulatory limits. It often works synergistically with other UV filters to provide broad-spectrum protection.

Despite its widespread use, octinoxate has faced scrutiny due to potential environmental concerns, particularly its impact on coral reefs. Some studies suggest it may have estrogenic effects, though the clinical significance in humans remains debated. Regulatory bodies in some regions have imposed restrictions on its use in sunscreens.

When formulating with octinoxate, it's crucial to consider its photostability and potential interactions with other ingredients. Proper encapsulation or combination with photostabilizers can enhance its performance and reduce potential irritation risks.
