Abstract
Abstract Liquid detergent compositions, particularly for use as hard surface cleaners, comprising 1%-20% surfactant, 0.5%-10% mono- or sesquiterpenes, and 0.5%-10% of a polar solvent having a solubility in water of from 0.2% to 10%, preferably benzyl alcohol. The compositions provide excellent cleaning of both greasy and particulate soils, improved surface appearance, excellent formulation homogeneity, stability and viscosity characteristics as well as good suds control.
