AI Technical Summary
Topical compositions, particularly emollients, pose a significant fire hazard due to their flammability when dried on fabrics, leading to accidents and increased risk for vulnerable populations, and they often adhere stubbornly, causing unexpected flammability even after washing.
Incorporating urea into topical formulations as an additive to enhance flame retardancy, utilizing urea's thermal decomposition to form a char and release non-flammable gases, thereby reducing fabric flammability and ensuring the formulation can be effectively washed off.
The urea-containing formulations exhibit reduced flammability on fabrics, comparable to untreated fabrics, and can be completely removed through ordinary washing, mitigating fire risks and maintaining safety.
