?? Key Characteristics and Applications 

The core value of 2-ethanaminohydroxybenzoic acid hexyl ester lies in its excellent photostability. It can effectively absorb ultraviolet rays in the UVA band (with the peak absorption wavelength at 354 nm), thereby protecting the skin from photodamage. 

Good light stability: Compared to some other sunscreens, it is less prone to decomposition under sunlight, can maintain its protective effect for a long time, and has good compatibility with various cosmetic ingredients. 

Regulatory approval status: It has been approved for use in the European Union since 2005. The maximum allowable concentration in sunscreen products is 10%, and it has also been approved for use in Japan, Taiwan of China, and other regions. 

⚠️ Safety and Operating Instructions 

Although this component is safe for use in cosmetics at the specified concentration, precautions still need to be taken during industrial-scale operations. 

Environmental ecological impact: It is necessary to be aware that it may pose potential harm to aquatic organisms and should be avoided from being released into the environment at will. 

Personal protection: During operation, appropriate protective equipment (such as protective glasses and gloves) should be worn, and the operation should be carried out in a well-ventilated environment. Avoid direct contact with skin and eyes.
