| Hazard Information | Back Directory | [Description]
Etocrylene is an organic ester that appears as an off-white crystalline powder and functions as a UV absorber. When applied to the skin, this product absorbs UV rays. It can also be used to protect cosmetics and personal care products from deterioration. This product can be used in the formulation of sun protection products, as well as bath, skin, cleansing, hair, nail and fragrance products. | [Uses]

The preparation method of Ethyl 2-cyano-3,3-diphenylacrylate includes the following steps: add cyclohexane and benzophenone to the reaction kettle, wait until the benzophenone is completely dissolved, then raise the temperature to 102-104°C and keep it warm. Then, add sodium bicarbonate as a catalyst, add ethyl cyanoacetate into the dripping storage tank, slowly add ethyl cyanoacetate dropwise into the reaction kettle, and react for 16 to 18 hours. During the reaction, the water generated is separated in time, and the reaction is completed. The product Ethyl 2-cyano-3,3-diphenylacrylate is obtained. | [Properties and Applications]
Ethyl 2-cyano-3,3-diphenylacrylate, another name Etocrylene, belongs to acrylic acid or the like UV light absorbers and is mainly used in making UV light absorbers in plastics, coating, dyestuff, vehicle glass, makeup, sun-screening agent. Because acrylate-based, two phenyls of this product and carbonyl can form a larger π key; thus, the structure shape of this product has extremely strong ultraviolet absorption ability.
