Diethylamino hydroxybenzoyl hexyl benzoate

Описание

Diethylamino hydroxybenzoyl hexyl benzoate is an organic compound belonging to the class of benzophenones, commercially used as UVA filter and is anticipated to provide reliable protection against free radicals and premature skin aging, mainly caused by shortwave UVA radiations.

Использование

Diethylamino hydroxybenzoyl hexyl benzoate is a UV filter with high absorption in the UV-A range. Minimizing the overexposure of human skin to ultraviolet radiation that may lead to acute and chronic photodamage, diethylamino hydroxybenzoyl hexyl benzoate is an oil-soluble UV filter that may be incorporated in the oil phase of emulsions. Diethylamino hydroxybenzoyl hexyl benzoate was approved in Europe in 2005, and is also marketed in the U.S., South America, Mexico, Japan and Taiwan. It has a chemical structure similar to the classical benxophoenone drug class, and displays good photostability. It is used in concentrations up to 10% in sunscreen products, either alone or in combination with other UV absorbers.

прикладной

Hexyl 2-[4-(diethylamino)-2-hydroxybenzoyl]benzoate may be used as a test material in investigating the structural elucidation of its transformation products in chlorinated water using liquid chromatography coupled to mass spectrometry.

Профиль безопасности

Diethylamino Hydroxybenzoyl Hexyl Benzoate is generally regarded as safe for cosmetic use. It has a low likelihood of causing skin irritation or allergies. Concerns about cancer risk due to its use in cosmetics are largely unsubstantiated, but research is ongoing. However, pregnant individuals should consult with a healthcare professional before use.

Синтез

Expose 3 mL of a 0.018 mg/mL solution of 3-diethylaminophenyl 2-hexanoxycarbonylbenzoate in methanol to UV-B radiation in a Luzchem LZC-4 photoreactor equipped with 16 broad band UV-B lamps (LES-UVB-01) at 35 °C to obtain Diethylamino hydroxybenzoyl hexyl benzoate.

в пробирке

Diethylamino hydroxybenzoyl hexyl benzoate (DHHB) absorbs UV-A radiation with a peak at 354 nm. The molar absorption coefficient of Diethylamino hydroxybenzoyl hexyl benzoate in EtOH at 25°C is obtained to be 39 000 mol/dm 3 /cm at 354 nm. The emission spectrum of Diethylamino hydroxybenzoyl hexyl benzoate in EtOH is dependent on the excitation wavelength.
