Product Introduction

  • Padimate O is an excellent UV absorber in UVB region, and also its maximum UV absorption top is 311nm (ethanol option). As a reliable anti-ultraviolet component, it is commonly made use of in sunscreen cosmetics abroad.
    The FDA classifies sunscreens including the product’s active ingredients as Category 1 suggested cosmetics.
     Today, with the quick development of sunscreen market year by year, the raw materials of isooctyl dimethylaminobenzoic acid (photoinitiator EHA) need to be imported from abroad every year to be made use of as anti-aging representative of industrial items.
     Therefore, it is of wonderful useful importance to examine the synthesis procedure of p-dimethylaminobenzoic acid (photoinitiator EHA), as well as it is also valuable to recognize the localization of the item.
  • Zhi Shang Chemical is committed to the production of high-quality Padimate O a first-class production line to ensure a stable supply of products to meet the needs of different markets.
