In this study an attempt was made to formulate cosmetic gel using Maranta arundinacea (arrowroot powder) Arrowroot contains flavonoids which is known for its anti-inflammatory properties, antibacterial properties from long time. It has earned a reputation as an elegant, lightweight, all-natural absorbent powder with added skin-nourishing, reduce oiliness, anti-inflammatory properties, anti-irritant properties and for treating wounds from historical times. The rhizome of the plant was processed to obtain arrowroot powder. The cosmetic gel was developed using two polymers carbopol 934 and sodium carboxy methyl cellulose (sodium CMC) in different ratios as gelling agents using dispersion method. The formulated gel was evaluated for various physicochemical factors like physical appearance, homogeneity, spread ability, pH and viscosity measurements. Cosmetic gel prepared using carbopol 934 by dispersion method in 1: 5 ratio showed better results in all parameters compared with sodium carboxy methyl cellulose. The best formulation F3 was tested for its antimicrobial property against Staphylococcus aureus by comparing the zone of inhibition with the standard drug (Azithromycin) and blank gel. F3 formulation showed a zone of inhibition of 15.2 mm above the minimum inhibitory concentration. Stability studies for 3 months gave promising results. Thus, cosmetic gel of arrow root with Carbopol 934 in the ratio of 1:5 was found to be ideal gel for acne treatment and skin rejuvenating purpose.
