Broad Spectrum Sunblock Transfer Device Presents Novel Application of SPF on High Risk Areas

Jenni Mueller and Noelle Wolf of Reading, PA have been awarded a patent (US Patent 12,109,278 B2) for a broad spectrum sun protection transfer device that they contend is similar to but distinct from UPF achieved with sun protection clothing and is designed to be safely adhered to the skin in high-risk areas.

The device encompasses backing paper, a silicone release coating affixed to the backing paper; and an “overlay sun protection” deposited on the silicone release coating. The sun protection is applied by placing the transfer film side down against the skin; applying water to the backing paper, wetting thoroughly with a sponge or cloth; waiting 20-30 seconds; and peeling away the backing paper leaving the sun protection adhered to the skin.

According to the inventors, high risk areas (HRAs) are the most common areas for basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) diagnosis. HRAs include the malar region, the dorsal surface of hands, the clavicular chest, the posterior neck and the upper helices of the ears. HRAs particularly include the ears, nose, and scalp where 70% of BCC is found, and the face, where SCC is most diagnosed. To that end, the inventors say there is a need for an easy to apply sunscreen product that fully blocks both UVA and UVB rays in high risk areas and is substantially unaffected by external factors such as sweat and water.

The transfer film retains its composition for longer periods of time than any existing lotion, stick, or spray, according to the patent filing. The novel application process, according to the filing, allows a person’s high risk areas to be more fully protected both in duration and in the percentage of UVA and UVB radiation blockage.
