Exposure of UV light can cause skin rashes and sunburn, stimulating the formation of melanin. Long term UV exposure also can cause skin cancer. One way that can reduce negative impact of UV exposure is by using sunscreen. The aims of this study were to obtained the best ratio of seaweed P. australis and E. cottonii slurry to produce sunscreen cream and as well as obtaining sunscreen formulation with good stability. Creams were formulated consist of cream with different ratio of seaweed P. autralis and E. cottonii slurry, i.e. A (control), B (1:1), C (2:1) and D (1:2). The commercial creams product also used as a comparator (KI and KII). The best ratio of P. australis and E. cottonii slurry was showed on cream B (1:1). Sunscreen creams have a good level stability, with no phase separation of dispersant and dispersed phase, and also no discoloration. Sunscreen creams have at least 1 year shelf life as there was no phase separation after centrifugal force at 3,800 rpm for 5 hours.
