Study on Moisture Retention of Aloe

Moisture retention of aloe was studied by using the method of measuring the ratio of water lose for sample. It was proved that aloe is of good moisture retintion. The best concentration of aloe jujce from moisture retention is 40 %～60 %( w /%).The moisture retention of aloe varies with its formulation system.In emulsion system, the best concentration of moisture retention is 40 %～50 %,under which,aloe moisture retention is better than 5 % glycerine.Under relative dry condition (RH=43.3 %),aloe moisture retention is even better than 10 % glycerine. In water base(gel) system,the best concentration is 40 %～60 %,under which,aloe moisture retention is very close to glycerine,and is corresponding to hyaluronic acid.
