Abstract
A pine oil type cleaning concentrate composition comprising as essential constituents: pine oil, one or more pine oil solubilizing agents, cationic surfactant, anionic surfactant, a surfactant compatibilizing agent, and water. Compositions according to the invention feature reduced levels of volatile organic contents, including reduced amounts of pine oil, yet provide good blooming characteristics upon mixing of the concentrate composition with a further amount of water to produce a cleaning composition therefrom. The pine oil cleaning compositions may further include conventional additives, including germicidal agents, viscosity modification agents, fragrances (natural or synthetically produced), foaming agents, detersive agent, co-surfactants, and coloring agents.
