Description

Isoamyl 4-Methoxycinnamate is a synthetic organic ester widely recognized for its efficacy as a UV filter. This compound matters for its ability to absorb ultraviolet B (UVB) radiation, providing critical protection against sun damage. It is primarily needed by manufacturers in the personal care and cosmetics industries for formulating sunscreens, daily moisturizers, and other skincare products. Its favorable solubility profile also makes it a versatile ingredient for various emulsion systems.

Application

• Broad-Spectrum Sunscreen Formulations: A key active ingredient for absorbing UVB rays to prevent sunburn and skin damage.
• Daily Wear & Anti-Aging Products: Incorporated into day creams, lotions, and foundations to provide everyday protection against photoaging.
• Lip Care Products: Used in lip balms and sticks to protect the delicate lip area from UV exposure.
• Hair Care Products: Added to hair sprays, serums, and leave-in conditioners to shield hair from UV-induced degradation and color fading.
• Decorative Cosmetics: Enhances the UV protection profile of makeup products like tinted moisturizers and BB/CC creams.
• After-Sun & Soothing Lotions: Supports skin recovery in post-sun exposure products by preventing further UV damage.
