Abstract

Extreme of heat and incresilng unpredictable weather conditions which occur globally have led to thermal discomfort and increasing in body temperatures, particularly children and the elderly. Today, existing of cooling patches sold in the market as a solution to this issues are expensive, utilise synthetic chemicals and contribute to environmental problems. To address these disadvantages, the innovation idea name as TriCool Patch was developed which provide  natural, cost-effective, and eco-friendly cooling solution. This innovation integrates three natural ingredients incorporating with biodegradable hydrogel matrix to achieve a triple cooling mechanism. These three ingredients, aloe vera, cucumber, and mint, provide their own function in this cooling patch as a moisture-retaining hydrogel, enhance cooling through evaporation, and provide a refreshing sensation, respectively. The preparation involves three steps, which are extraction, mixing the ingredient with specific ratios, solidify to form a flexible patch. The results demonstrated that the TriCool Patch effectively reduces skin surface temperature by approximately 3.1°C, improving thermal comfort during heat exposure. Beside its function to reduce our body temperature for thermal comfort, it also promotes green chemistry and sustainable product development.
