The science behind effective cosmetic formulations often hinges on specialized ingredients that provide essential protective functions. NINGBO INNO PHARMCHEM CO.,LTD. focuses on Benzophenone-4, a key water-soluble UV filter that plays a vital role in product stability and performance. Also known by its INCI name Sulisobenzone, this compound is a critical tool for cosmetic chemists.

Benzophenone-4 is recognized for its ability to absorb UV radiation, particularly in the UVA spectrum, and to a lesser extent, UVB. This makes it an important component in sunscreens and other products designed to protect the skin from sun damage. However, its utility in cosmetics extends to its function as a powerful photoprotectant for cosmetics. Many sensitive ingredients within formulations, such as vitamins, antioxidants, and fragrance compounds, can degrade when exposed to UV light, leading to a loss of efficacy or unpleasant aesthetic changes. Benzophenone-4 absorbs this harmful UV energy, thereby preserving the integrity of these ingredients and extending the product's shelf life.

A significant application where Benzophenone-4 shines is in the preservation of color. It is extensively used in products where color stability is paramount, such as hair care items. The compound helps to protect hair dyes from fading caused by UV exposure, ensuring that hair color remains vibrant and consistent. This capability to prevent hair dyes from fading is a key reason for its inclusion in many hair coloring and styling products.

The market actively seeks reliable sources for UV absorber Benzophenone 4. Its water solubility is a significant advantage, allowing for its seamless integration into a wide array of product types, from lotions and creams to sprays and gels. Formulators also appreciate its ability to work synergistically with other ingredients, sometimes enhancing their skin penetration.

While discussions around potential allergens and endocrine-disrupting properties exist, regulatory assessments confirm its safety when used within prescribed concentration limits. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-purity Benzophenone-4, ensuring that our clients can confidently incorporate this essential ingredient into their formulations to achieve superior product stability and protective benefits.
