Science
Mechanism of Action
This molecule utilizes a benzotriazole core to intercept UVA and UVB radiation, converting photon energy into low-level heat that dissipates without harming the skin or formula. Its methacrylate functional group allows it to covalently bond into the product's polymer matrix, creating a permanent internal shield that prevents the stabilizer from leaching or losing efficacy over time.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 Demonstrated 0.5% concentration provides superior color suppression and prevents light-induced yellowing in polymer-based systems.
- 02 Shown to effectively shield UV-sensitive additives in ophthalmic and topical applications within the 0.1% to 2.0% range.
Transparency
Dusting Analysis
Because it is a highly efficient stabilizer, it is effective at low concentrations; however, levels below 0.05% typically indicate 'label claim' usage rather than functional formula protection.
The Formula
Formulation
Stability
Maintains excellent stability under standard conditions but may undergo hydrolysis in highly acidic (pH <3.0) or alkaline (pH >9.0) environments. Requires an oil phase for proper dispersion.
