Avobenzone

Sinónimos: Butyl methoxydibenzoylmethane, 1-(4-tert-Butylphenyl)-3-(4-methoxyphenyl)propane-1,3-dione, 4-tert-Butyl-4′-methoxydibenzoylmethane, BMDBM, Avobenzone, Parsol 1789, Eusolex 9020

Avobenzone has become the benchmark UVA filter in modern sun care, driven by tightening global regulations and consumer demand for broad-spectrum protection. Formulators rely on it because it delivers reliable UVA coverage across a wide range of emollients and spray systems, and it remains one of the few organic filters approved in both the US and EU.

Chemically, avobenzone is a dibenzoylmethane derivative—specifically 1-(4-tert-butylphenyl)-3-(4-methoxyphenyl)propane-1,3-dione. The molecule exists predominantly in its enol form, a configuration that absorbs strongly in the UVA region (320–400 nm). It is a synthetic compound produced through a multi-step organic synthesis, not a botanical extract, and is supplied as a high-purity crystalline solid.

Our avobenzone is standardized to ≥99.0% by HPLC, a purity level that minimizes the risk of photodegradation and color drift in finished formulas. It is compatible with a broad range of UV filters, including octocrylene and ethylhexyl methoxycinnamate, and is suitable for O/W and W/O emulsions, anhydrous gels, and spray formulations.

Descripción general y composición del producto

Avobenzone is a single, well-defined organic molecule. Its photostability can be enhanced by pairing with triplet-state quenchers such as octocrylene or with film-formers that reduce its mobility in the formula. The enol tautomer is the active UV-absorbing species; keto-enol equilibrium shifts with solvent polarity and pH.

Because avobenzone is oil-soluble and essentially water-insoluble, it is typically incorporated into the oil phase during emulsification. Heating above 80°C should be avoided to prevent degradation, and chelating agents are often added to protect against metal-ion-induced color changes.
