Abstract: An insecticidal bait composition which is particularly useful against social insects, such as cockroaches and ants is disclosed. The bait composition comprises a solid or semi-solid bait matrix including a food material for an insect and one or more non-microencapsulated insecticides in an amount effective to act essentially as a primary kill agent and one or more microencapsulated insecticides, excluding pyrethroids, in an amount effective to act essentially as a secondary kill agent, the non-microencapsulated insecticide and microencapsulated insecticide being the same or different.

Abstract: Combinations of polymer compounds and hair treatment compositions containing them are described, which have improved film-forming properties and improved hair-fixing properties, particularly increased elasticity of the polymer film or the treated hair. The polymer compound combinations include at least one terpolymer of vinyl pyrrolidone, vinyl caprolactam and basic acryl amide monomer and at least one anionic or anionizable polymer with anionic or anionizable groups.
