Abstract
A cleaning composition with a limited number of natural ingredients contains an anionic surfactant, a hydrophobic syndetic, a hydrophilic syndetic and a solvent. The cleaning composition can be used to clean laundry, soft surfaces, and hard surfaces and cleans as well or better than commercial compositions containing synthetically derived cleaning agents.
