ShieldBiso™ SX (Terephthalylidene Dicamphor Sulfonic Acid)

ShieldBiso™ SX （Terephthalylidene Dicamphor Sulfonic Acid） is a potent UVA sunscreen agent recognized for its impressive effectiveness in protecting the skin from harmful UVA radiation. This ingredient is designed to offer substantial UVA absorption while exhibiting minimal skin absorption, making it a valuable component in many sun protection formulations. Despite its strong performance, ShieldBiso™ SX does have limitations, such as not covering the entire spectrum of UVA wavelengths and a potential degradation of up to 40% after two hours of sun exposure. As a result, it is often used in combination with other sunscreen agents to ensure comprehensive protection.

Key Benefits and Features:

1. Significant UVA Absorption: ShieldBiso™ SX is highly effective in absorbing UVA radiation, which is critical for preventing long-term skin damage and aging. It offers excellent stability and efficiency, reducing the risk of decomposition during use. Importantly, it exhibits minimal penetration into the skin, making it a safe choice for those concerned about skin absorption.

2. Versatile Use in Skincare Products: This ingredient is frequently incorporated into a variety of fundamental skincare products, including sunscreens, sunscreen liquids, gels, sprays, BB creams, and similar formulations.

3. Wide Absorption Spectrum: ShieldBiso™ SX covers a broad UVA absorption spectrum from 290 to 390 nm, with peak absorption occurring at 345 nm. This range is essential for providing comprehensive protection against UVA rays, though it does not encompass all UVA wavelengths.

4. Safety and Compatibility: Generally considered safe for use by pregnant women, ShieldBiso™ SX does not contribute to acne formation, making it a suitable option for individuals with sensitive or acne-prone skin.
