샴푸중 계면활성제의 생분해도와 인산염 및 중금속 함유에 대한 연구

The Studies of Biodegradabilities, Phosphates and Heavy Metals for Shampoos

The biodegradabilities of surfactants were measured for six kinds of shampoos in domestic market at present, and the phosphates and heavymetals are analyzed. Analysis results show that though they all come up to KS(Korean Industrial Standards), samples containing plenty of AOS and synthetic SLES have the lower biodegradability than the others. We knew the fact that thease smples are petroleum surfactants have the lower biodegradability than surfactants extracted naturally. All of them the contents of phosphates and heavymetals are excellent for limitation of the cosmetic standards.
