Solubiliser
SunBoost-BOS
INCI: Butyl Octyl Salicylate
Formulator notes
Butyloctyl salicylate: an oil-phase solvent that keeps oil-soluble UV filters dissolved and evens out the film, which raises measured SPF. Use 1-10%.
Hold it The molecule in AR on a phone, in 3D anywhere else.
Open in the SPF Lab An in-silico simulator over the Sunbest range, pre-loaded with this filter.
Highlights
- Oil-phase solvent/emollient and solubiliser for oil-soluble UV filters.
- Enhances SPF when paired with filters: improves uniform film formation and effective coverage.
- A salicylate ester: a lipophilic carrier that lowers interfacial tension, improving spreadability and skin feel.
