Estimation shelf life on hand sanitizer that utilizes waru leaf (Hibiscus tiliaceus) waste using the accelerated method with arrhenius model

Abstract

Reprocessing organic waste such as leaves and fruit peels can produce natural hand sanitizers with novelty or useful findings. Waru leaf hand sanitizer is a new innovation that uses natural ingredients and low alcohol. Natural extracts in products are still susceptible to damage, so an estimated shelf life is needed. Estimated shelf life is related to product quality, both producers and consumers really need it. Estimating the shelf life of an item is one way to find out how long the product can be stored. By using the ASLT (Accelerated Shelf Life Testing) method with the Arrhenius model, this study aims to determine how long the waru leaf hand sanitizer gel can last. For 18 days, the waru leaf hand sanitizer was stored at storage temperatures of 30°C, 35°C, and 40°C. Direct observation of the object of research (pH, texture, aroma, color, and absorbency) was used to obtain research data. Waru leaf hand sanitizer has 108.48 days (3.17 months) shelf life at 30°C, according to the results.
