UV filters are essential ingredients in sunscreens and UV-protective cosmetics, designed to shield skin from harmful UVA and UVB rays. They fall into two main categories: chemical filters (like avobenzone or octinoxate), which absorb and neutralize UV radiation, and mineral filters (such as zinc oxide or titanium dioxide), which physically block rays by sitting on the skin’s surface. Choosing the right UV filter ensures both effective sun defense and skin compatibility.
Ellagic Acid
Ellagic Acid is a naturally occurring polyphenolic compound found in numerous fruits, nuts, and vegetables such as pomegranates, strawberries, raspberries, walnuts, and cranberries. It is a potent antioxidant known for its ability to scavenge free radicals and chelate metal ions. Due to its significant anti-inflammatory, anti-carcinogenic, and anti-viral properties, Ellagic Acid has gained extensive interest in pharmaceutical, nutraceutical, cosmetic, and food industries. It appears as a yellow to light brown crystalline powder, insoluble in water but soluble in organic solvents like ethanol and DMSO.
Methoxy benzophenone Sulfonic Acid
Methoxy Benzophenone Sulfonic Acid is a water-soluble UV filter widely used in sunscreen and cosmetic formulations. It absorbs ultraviolet (UV) radiation, primarily in the UVB range, protecting skin and products from harmful effects of sun exposure. This compound appears as a white to off-white powder or crystalline solid and is valued for its photostability and broad-spectrum UV protection.
Zinc Oxide USP
Zinc Oxide USP is an inorganic white powder composed primarily of ZnO. It is widely used as a functional additive in rubber, ceramics, glass, paints, and chemical industries. Known for its excellent chemical stability, UV-absorbing capability, and reactivity with acids and alkalis, this grade is tailored for industrial applications where high purity is not mandatory but consistent quality and performance are essential.
