The invention discloses skin cleaning composition. The prescription of the composition comprises the following components by mass percent: 15% to 50% of fatty acid and the soap thereof, wherein, fatty acid comprises the following components: 20% to 75% of fatty acid with the number of carbon atoms of 16 to 18, fatty acid with the number of carbon atoms being below 15 and above 16, (the mass ratioof the two fatty acids are 15:90 to 42:50); 0.1% to 5% of polymer viscosifier; 0.01% to 15% of neutralizer; 2% to 35% of alcohol; and water in balancing amount. The product of the skin cleaning composition has the advantages that the product foams quickly, the foam is fine and rich and can be rushed out by water quickly, and the product is temperate to the skin; the skin after cleaning is endowedwith feeling of smoothness and moisture, the stability is good within a wide temperature range (minus 15 to 48 DEG C), the product does not flow at a high temperature of 40 DEG C, does not delaminateat a high temperature of 48 DEG C and does not harden at a low temperature of 0 DEG C; moreover, the product is superior in the storage life and the shelf life.
