Abstract
Systems and methods for predicting a Sun Protection Factor (SPF) in vitro, such as by spectral/image analysis, of a sunscreen formulation are described.
Claims20
A system for generating an ultraviolet (UV) absorption analysis comprising:
- a skin tissue phantom impregnated with a marker configured to absorb UV light and generate a detectable signal in response to absorbing the UV light;
- an interrogator configured to generate interrogation data based on the detectable signal generated by the marker in response to the UV light absorbed by the marker;
- and
- an analyzer communicatively coupled to the interrogator and configured to receive the interrogation data from the interrogator, wherein the analyzer is configured to generate the UV absorption analysis based at least in part on the interrogation data.
1 more element
A method of generating a UV absorption analysis of a sunscreen formulation comprising:
- receiving, by an analyzer from an interrogator, interrogation data generated by the interrogator, the interrogation data based at least in part on detectable signal generated by a marker impregnated in a skin tissue phantom in response to the marker absorbing UV light;
- wherein at least a portion of the skin tissue phantom is coated with the sunscreen formulation, and
- generating, by the analyzer, the UV absorption analysis of the sunscreen formulation based at least in part on the interrogation data.
