Description
Bisoctrizole (also known as Methylene Bis-Benzotriazolyl Tetramethylbutylphenol) is a broad-spectrum, hybrid UV filter widely used in high-performance sunscreen formulations. Unique in its composition, Bisoctrizole functions both as a mineral and organic filter, providing exceptional protection against UVA (320–400 nm) and UVB (280–320 nm) radiation. This dual action helps prevent sunburn, photoaging, and long-term UV damage, making it an ideal choice for comprehensive sun protection.
Unlike many chemical sunscreens, Bisoctrizole is photo-stable, meaning it does not degrade significantly upon sun exposure. This stability ensures consistent protection over extended periods outdoors. It also has the ability to stabilize other UV filters, enhancing the overall performance and longevity of sunscreen formulations.
Bisoctrizole exists as microfine particles suspended in the water phase of an emulsion, giving it a lightweight, non-greasy texture and minimizing the risk of leaving a white cast. This makes it suitable for daily wear in both skincare and cosmetic products, from lotions and creams to tinted moisturizers and makeup with SPF.
In addition to protecting skin, Bisoctrizole helps preserve the color and integrity of products by shielding them from UV-induced degradation. It is well tolerated by most skin types, including sensitive skin, due to its low penetration into the skin layers and minimal irritation potential.
Regulatory approval for Bisoctrizole varies: it is allowed up to 10% concentration in the European Union, Australia, and parts of Asia, but has not yet been approved for use in the United States.
Thanks to its broad-spectrum coverage, high stability, and compatibility with other sun filters, Bisoctrizole is a preferred choice in advanced sunscreen technologies, offering reliable, long-lasting protection while maintaining a comfortable skin feel.
