Abstract
In accordance with the present invention, a stable aqueous detergent composition is provided which comprises a homogeneous mixture of: PA1 a) pine oil; PA1 b) surfactant; PA1 c) at least one aliphatic alcohol containing 1 to 5 carbon atoms; PA1 d) at least one water soluble glycol mono C.sub.1-4 alkyl ether solvent having a solubility in water at 25.degree. C. in excess of 10 g/100 g. water; and PA1 e) water; the relative proportions of said alcohol and said glycol being in the weight ratio of about 1:2 to 2:1 and the combined amount of said alcohol and said glycol present in said composition being in the range of from about 1 to less than about 7 wt. %. In the more preferred embodiment of the invention, the composition further contains an insect repelling amount of at least one insect repellent selected from the group consisting of alkyl or alkaryl amides having from about 5 to 16 carbon atoms. The compositions of the invention provide clear, stable pine oil dispersions at pine oil concentrations of up to about 25 wt. % which do not separate or cloud up after periods of storage and which have a very low content of volatile organic compounds.
