A Sunscreen Based on Bioadhesive Nanoparticles

Status Completed

Clinical Trial Summary

The initial focus of the study will be on safety, sun protection factor (SPF) characterization, and substantivity (duration of protection) studies. The primary outcome of the study will be to measure the sun protection factor (SPF) of a bioadhesive nanoparticles (BNP) formulation in 20-25 healthy volunteers with fair skin.

Clinical Trial Description

The purpose of this study will be to evaluate the duration of protection and efficacy of a novel bioadhesive nanoparticle sunscreen in 20-25 human volunteers.This technology makes sunscreens safer and longer-lasting by encapsulating UV sunscreen active agents in non-toxic nanoparticles. Strong preclinical data exists demonstrating the potential for improved safety, long-duration of retention, and increased effectiveness of this product.

This innovative solution focuses on preventing damage caused by UV exposure through the use of a nanoparticle delivery vehicle. The bioadhesive feature of this technology enables longer protection. In addition, encapsulation of the UV filter in a bioadhesive nanoparticle (BNP) improves filter photo-stability, delays filter photo-degradation, and prevents reactive oxygen species (ROS) escape, thereby reducing the risk of cell damage and epidermal toxicity from UV filters.

Furthermore, the bioadhesive feature of our technology eliminates penetration into deeper skin layers or into the blood, minimizing the potential side-effects of UV filters. It is believed that the translation of this technology will provide a longer-lasting, safer, more protective UV sunscreen. ;
