Abstract
Glycolic acid is a α-hydroxy acids (AHAs). It are used in skin lightening creams. It were developed formulation of 20% glycolic acid creams. The creams were made using 4% of polyacrylamide, C13-14 isoparaffin, laureth-7 as a thickening agent for cream gels and emulsions base and combination of 1.5% of polyacrylamide, C13-14 isoparaffin, laureth-7 and 5% of a glukolipid of vegetable origin as emulisufier agent. Then the physicochemical stabilities were tested using climatic chamber for 30 days at 40˚C with 75% Relative Humidity (RH). The parameters stability observed were organoleptic, droplet size, density, viscosity, emulsion type, phase separation, pH and concentration of acid glikolat.Organoleptis, droplet size, density, viscosity, type of emulsion and phase separation of all of creams were stable, but the pH decreased during the storage time. The time of the concentration of glycolic acid remaining to 90% in cream using using 4% of polyacrylamide, C13-14 isoparaffin, laureth-7 and using combination of using 4% of polyacrylamide, C13-14 isoparaffin, laureth-7 with 5% of a glukolipid of vegetable origin were 30 and 32 days respectively.
