In the dynamic world of cosmetic science, ensuring the longevity and efficacy of products is paramount. NINGBO INNO PHARMCHEM CO.,LTD. highlights the critical role of Benzophenone-4, a water-soluble UV filter, in achieving these goals. Often recognized by its INCI name, Benzophenone-4, or its synonym Sulisobenzone, is a key ingredient that addresses multiple formulation challenges.

The primary function of Benzophenone-4 is to act as a UV absorber. It is particularly effective in filtering UVA radiation and offers some protection against UVB rays. While it can be combined with other sunscreens to provide more comprehensive sun protection, its utility extends far beyond direct skin application. One of its most significant contributions is its ability to stabilize cosmetic formulations. Many cosmetic ingredients, including fragrances and active compounds, are sensitive to light and can degrade or oxidize when exposed to UV radiation. Benzophenone-4 acts as a photoprotectant, shielding these delicate components and thus extending the product's shelf life.

A notable application of Benzophenone-4 is in the preservation of color. For instance, it plays a crucial role in ensuring that hair dyes do not fade when exposed to sunlight. This makes it an invaluable component in hair coloring products and styling agents that aim to maintain color vibrancy. The ability to protect hair dyes from fading is a testament to its photoprotective capabilities.

Furthermore, Benzophenone-4 can enhance the penetration of other ingredients into the skin. While this property needs careful consideration in formulation, it can be leveraged to improve the delivery of beneficial compounds. The market for UV absorber Benzophenone 4 continues to grow as formulators seek reliable ingredients to improve product performance and stability.

While generally considered safe for use in cosmetics within regulatory limits (often capped at 5% in Europe), there has been ongoing discussion regarding its potential as an allergen and its impact on hormonal balance. However, regulatory bodies have deemed it safe for use as a UV filter and photoprotectant when adhering to these concentrations. For those looking to buy Benzophenone-4 for their formulations, understanding these properties is key.
