Improved a la càrte sun protection based on precursors’ technology

SMART UV Filters are suitable photochemical precursors with the ability to absorb UV light.

These compounds absorb UVB radiation (290-320nm) and, through a photochemical transformation that takes place when exposed to sun light (photo-Fries reaction), they become UVA absorbers (320-400nm).

The final compound is then a broadband filter (UVA+UVB).

One of the main drawback of current UV filters is that they degrade with certain doses of UV irradiation, loosing their protective effect. This is shown in the graph with avobenzone, the commercial UVA filter of reference.

SMART UV filters not only resist UV degradation but they also absorb at the UVA range in a dose-dependent way, providing a long-lasting and high protection.

Silica encapsulation with covalent bonding to avoid toxicity to humans and the environment.

SPF increases progressively and is dependent on irradiation dose.
UVA protection increases progressively and is dependent on irradiation dose.
Broad spectrum coverage achieved after 30 min irradiation.

Note: initial irradiation time tested was 30min. Broad spectrum coverage could be achieved earlier than this time.

Our molecules are organic covalently bonded to a silica matrix, a sort of encapsulation process where the UV filter is 3D anchored to a capsule.

  • This union prevents the release of the encapsulated UV filters at the systemic level in humans and in ecosystems.
  • As opposed to current UV filters, SMART UV filters do not generate by-products when exposed to sunlight, limiting potential toxicologic effects.
  • In-house studies have shown over a 99% reduction of UV filter release in the environment both before and after irradiation.
