AI Technical Summary
Technical Problem
Existing sunscreen compositions struggle to stabilize a combination of liquid and solid UV absorbers and solid absorbents, leading to instability and difficulty in achieving high SPF levels while maintaining good aesthetics.
Method used
A sunscreen composition comprising organic UV filters, polymeric emulsifiers, and solid absorbents, stabilized by trilaureth-4 phosphate, forming a phase-stable oil-in-water emulsion with high SPF levels and desirable aesthetics.
Benefits of technology
The composition achieves SPF levels of at least 30, preferably 50, with a lightweight, fast-absorbing, and aesthetically pleasing fluid emulsion, maintaining stability for at least two weeks at room temperature.
