      Abstract
      The objective of the study is to utilize carrageenan into skin lotion making as a thickener, stabil iser, emulsifier and humectan. The concentration of carrageenan that used were 0%, 1%, 2%, and 3%. Paramet er observed were sensory charracteristic, chemical charracteristic, and physic. Skin lotion made from the best carrageenan concentration stored for 30 days in room temperature, and then compared with other skin lotion added with and without setyl alcohol, and also skin lotion without carrageenan. Parameter obs erved were skin humidity, sensory charracteristic, physical and chemical charracteristic, and also total m icrobial after 3 months storage. The results showed that skin lotion with 2% carrageenan has the best quali ty with parameter sensory of panel preferences was from quite likely until most likely, pH 7,5; viscosity 56 75 cP, and emulsion stability was 100%, skin humidity value has the highest percentage and showed the lowe st decrease of skin humidity compare with product with and without setyl alcohol, and product without c arra- geenan. Panel preferences decreased during 30 days storage even physical and chemical charracteristi c were in still good condition, pH product tend to be constant, where viscosity increased. After 3 mo nths storage, total microbial was 1,0 x 10 1 cfu per gram, while the product added with setyl alcohol has no microbial colony. Poduct without setyl alcohol and without carrageenan has 2,0 x 10 1 cfu per gram. The product is safe to use, where total microbial was below standard of SNI 16-4399-1996 that is 1,0 x 10 2 cfu per gram.
