OPTIMIZATION OF CARBOPOL 940 AND PROPYLENE GLYCOL CONCENTRATION ON THE CHARACTERISTIC AND INHIBITORY EFFECT OF ETHANOL EXTRACT GEL OF PAPAYA (Carica papaya L.) SEEDS AGAINST Staphylococcus aureus

Abstract

Papaya (Carica papaya L.) seeds contain alkaloids, flavonoids, tannins, phenolic compounds and saponins have been proven its synergistic effect in inhibiting the growth of Staphylococcus aureus. In this research, ethanol extract of papaya seeds was formulated in gel preparations. Optimization of the composition of the gelling agent and humectant was carried out to obtain the gel preparation of papaya seed ethanol extract with good physical properties and stability. The parameters used to determine the stability of the preparation are Physical properties which include viscosity, spreadability, and percentage of viscosity shift. Data analysis was performed using Design-Expert software version 12 and SPSS. The inhibitory activity test was carried out by the disk-diffusion agar method with Staphylococcus aureus ATCC 25923 as the test bacteria. The results of the inhibitory activity test of papaya seed ethanol extract at a concentration of 20% had moderate activity and at concentrations of 40%, 60%, 80% and 100% classified as strong against the Staphylococcus aureus. Carbopol 940 is dominant factor in influencing the response of viscosity (92.504%) and spreadability (59.539%). Preparations with good physical properties and stability were obtained on the use of carbopol 940 and propylene glycol as much as 1.06604 grams and 13.2146 grams respectively.

Stability and Sunscreen Activity of Nutmeg Seed Oil Emulgel With Carbopol 940 Variation as Gel Base

“…The p value between formula compared to weekly sampling was 0.195 and p value within the formula was 0.063. Carbopol 940 provides good physical properties and stability (Yandri & Setyani, 2021). Vehicles such as gel base, apart from being able to maintain physical stability, are also able to maintain the stability of the effectiveness of the preparation (Hossann et al, 2007).…”

Enhancing the Physical Characteristics and Shelf Life of Rice Water (Oryza Sativa L.) Gel Shampoo: The Role of Propylene Glycol Concentration

“…With its chemical structure illustrated in fig. 1, PG contains two alcohol groups and is classified as a diol [15]. PG is widely used as an excipient, humectant, co-solvent, and penetration enhancer [16,17].…”

“…In addition, PG can facilitate the dissolution of chemicals and, at certain levels, can affect drug release [18]. This ingredient is used in various pharmaceutical dosage forms since it is generally known as a relatively non-toxic material [15]. This study aims to determine the effect of variations in PG concentration as a humectant on RW shampoo gel's physical properties and stability.…”

Formulation and Characterization of Hesperidin-Loaded Transethosomal Gel for Dermal Delivery to Enhance Antibacterial Activity: Comprehension of In Vitro, Ex Vivo, and Dermatokinetic Analysis

“…The formation of a gelling agent contributes significantly to the establishment of a structural system, which is a crucial determinant in the overall composition of the gel. The inclusion of humectants in the gel preparation serves to uphold its stability by facilitating moisture absorption and minimizing water evaporation [24]. Carbopol is a synthetic polymer derived from acrylic acid and offers effective viscosity control [25].…”

“…Carbopol is a synthetic polymer derived from acrylic acid and offers effective viscosity control [25]. The consideration of carbopol 934 as a gelling agent stems from its notable attributes, such as its exceptional stability, resistance to microbial degradation, and extensive utilization in both the pharmaceutical and cosmetic sectors [24].…”
