| Ethylhexyl Triazone Usage And Synthesis |
| Description |
As a new type of triazine UV absorber, ethylhexyl triazone has a large molecular structure and high UV absorption efficiency, has a broad-spectrum sunscreen effect, is the most powerful oil-soluble UV-B absorber on the market today, has high photostability and prevents UV-B-induced immunosuppression. It has strong water resistance and a good affinity for skin keratin. |
| Uses |
ethylhexyl triazone is the InCI name for octyltriazone. It is a uV filter and absorber. Clinical studies show high photostability and very high uVB-absorption capacity, particularly when compared to other popular uV filters. Studies also indicate that even low concentrations of ethylhexyltriazone in a sun care preparation can contribute significantly to the final product’s SPF. It appears to perform particularly well in synergy with zinc oxide. |
| Uses |
Ethylhexyl Triazone is used in sunscreen formulations as a UV filter to block out harmful ultraviolet light. |
| Definition |
Ethylhexyl triazone (octyl triazone; a derivative of PABA): Not authorized in the USA. Increases the effectiveness of other filters. Free radicals are released in sunlight. Very little data. Prudence (EWG 1 None)[1]. |
| Synthesis |
To the reactor was added 2000 mL of toluene, Sodium methoxide 103.6g and 1210mL isooctanol, heated and dissolved to dissolve, And heated to 110 ~ 115 °C, containing 1036g slowly added dropwise Methyl triazone 1500mL toluene solution was added dropwise, insulation reaction 8-10h, the reaction was continuously distilled to remove the methanol produced. The reaction is completed, and the solvent is distilled off. After the solvent is evaporated to dryness, 2500 mL of absolute ethanol is added. Crystallization of octyl triazone (UVT-150) product, filtration, Washed with anhydrous ethanol and water to obtain a UV absorber (UVT-150; Ethylhexyl Triazone)Product 1549g. |
