Bemotrizinol Chemical Properties,Uses,Production
Description
Bemotrizinol, or bis-ethylhexyloxyphenol methoxyphenyl triazine, is an organic UV filter found in over-the-counter sunscreen products. It primarily absorbs UV-A rays. Compared to older broad-spectrum chemical agents, bemotrizinol is more more fat soluble (oil soluble in cosmetic oils) to aid in efficacy and broad-spectrum activity. It is claimed to be photostable, which increases its onset of action and its efficiency in providing protection against UV-rays upon topical application. Bemotrizinol is commonly marketed as Tinosorb S and Escalol S.
Uses
Bemotrizinol is a broad-spectrum UV absorber, absorbing both UVA and UVB. Bemotrizinol is added to various sunscreens to absorb UV rays.
Definition
ChEBI: Bemotrizinol is a member of methoxybenzenes.
The INCI name of Bemotrizinol is bis-ethylhexyloxyphenol methoxyphenyl triazine
brand name
Tinosorb S (Ciba Specialty Chemicals).
Synthesis
In a three-necked flask equipped with a stirrer, a thermometer and a condenser, 40.30 g (0.1 mol) of 2,4-bis(2,4-dihydroxyphenyl)-6-(4-methoxyphenyl)-1,3,5-triazine, 29.02 g (0.21 mol) of potassium carbonate and 105 mL of N, N-dimethylformamide were added in sequence, and the temperature was raised to 100°C. Reflux and stir for 30 minutes; add 46.35g (0.24mol) of DMF solution containing isooctane bromide at a uniform rate within 1 hour, continue to reflux and stir at 100°C after the addition is complete, and monitor the reaction progress with a thin layer chromatography; after the reaction of the raw materials is completed, stop stirring, cool to room temperature, filter, add ethyl acetate to the filtrate for extraction, wash with saturated brine, dry the organic phase with anhydrous sodium sulfate, filter, and spin-dry the filtrate to obtain a colourless transparent oil, i.e. 50.4g of a crude product of bis-ethylhexyloxyphenol methoxyphenyl triazine (Bemotrizinol), with a yield of 80.2% and a purity of 89.90% detected by HPLC.
Advantages
The bis-ethylhexyloxyphenol methoxyphenyl triazine (Bemotrizinol) is a triazine ultraviolet absorbent, has efficient absorption in ultraviolet bands of UVA (320-400 nm) and UVB (280-320), has high molecular weight, is not easy to be absorbed by skin, has strong stability, and is widely applied to personal care and cosmetic products.
