Formulation and Evaluation of Facial Wash Gel Preparation from Celery Leaf Ethanol Extract (Apium graveolens L.) Against Staphylococcus aureus Bacteria

Facial wash is a facial cleansing soap that can clean oil and cosmetics that stick to the face. Usually facial wash has a low pH or close to the skin's normal pH, namely 4.5-6.5 and contains milder detergent. Researchers are to determine which celery leaf extract (Apium graveolens L.) is being evaluated as a facial wash preparation and to determine which facial wash preparation has inhibitory power for the growth of Staphylococcus aureus bacteria. This research is experimental using the maceration method. The sample used in this research was 10 kilograms of celery leaves. Results : Testing the pH of the celery leaf ethanol extract facial wash gel preparation for each F0, F1, F2 and F3 showed that the pH of the celery leaf ethanol extract facial wash gel preparation decreased due to the presence of acid compounds in celery leaves, causing the pH to decrease slightly but still within the pH range. topical, namely 4.5-7.0 and the pH of the celery leaf ethanol extract facial wash gel preparation above shows a relatively neutral pH which is still safe for the skin. The facial wash gel preparation of ethanol extract of celery leaves (Apium graveolens L.) has an inhibitory zone containing Staphylococcus aureus bacteria in K(+), K(-), F1 (5%), F2 (10%) and F3 (15%) with strong inhibition zone category. Researchers found that the ethanol extract of celery leaves can be formulated in the form of a facial wash gel. It is recommended that further research be carried out on the effectiveness of celery leaves with different concentrations and methods.
