The SolaStay trademark is synonymous with innovation and compliance—meeting the most difficult SPF and broad spectrum regulatory requirements globally. SolaStay S1 is the only singlet quenching stabilizer in the world, and works faster than other competing triplet quenching stabilizers. This allows the development of sunscreens with filter combinations that were once thought of as impossible, including inorganic/organic mixes and Avobenzone with Octinoxate.
SolaStay® S1 is the unique, highly efficient, singlet state quencher for Butyl Methoxydibenzoylmethane (BMDBM; Avobenzone) and Ethylhexyl Methoxycinnamate (OMC; Octinoxate). At a typical use level that matches the percentage by weight of Avobenzone in the formulation (typically 2-3%), it can markedly improve Avobenzone photostability, thereby allowing new heights in broad spectrum UVA and UVB photoprotection. Used at 1-3% with mineral UV filters and/or cosmetic colorants, it mitigates the photocatalytic and reactive oxygen species-generating activities of these oxides. To photostabilize photolabile anti-aging ingredients such as Cholecalciferol, Resveratrol, Retinol, Retinyl Palmitate and Ubiquinone in skin care products, 3 – 5% SolaStay® S1 is recommended.
SolaStay® P1 permits formulators to combine active ingredients once considered too photo-unstable to be effective. SolaStay® P1’s singlet state quenching makes for faster, more powerful photostabilization of sunscreens. It effectively photostabilizes Avobenzone and, as a polymer, it may also enhance the water resistance of products in which it is incorporated. Typical use level 1 – 5%.
