• inventive compositions and comparative compositions as insect repellent compositions has been determined using ants and German cockroaches, which are placed in a partially treated/partially untreated laboratory area (in total 200 m 2 ) under constant temperature and air-conditioning.
• a dosage of 240 ml of the tested composition per 5 litres washing liquid is applied onto a stone tile floor (100 m 2 ) and 20 ants or cockroaches (Blatella germanica) are placed in the arena and allowed to acclimatize for 10 min. The cockroaches are monitored for 1 hour and then removed from the arena. After the fragrance had aged for 8 hours and 24 hours, respectively, a fresh set of bugs is introduced into the laboratory area and again monitored as described above. The experiment is repeated three times to gain statistical significance. Repellency was defined as the percentage of insects that avoided the treated surface and was calculated according to the following formula: insects left on untreated surface
• the cleaning compositions of the present invention have superior and long lasting cockroach repellent effects.
• compositions of the present invention are effective to keep cockroaches away from surfaces, which have been cleaned with the cleaning compositions, even 8 hours and 24h after cleaning.
• use of the cleaning compositions of the present invention reduces the necessity of frequent use, but achieves satisfactory and long-term insect repellence effect.
• the cockroach repellence effect achieved with the compositions of Examples 2 and 4 to 7 is even superior compared to a commercial product containing the insecticide NMDA, use of which is critical for health and safety reasons.
• the cleaning compositions of the present invention further have superior and long lasting ant repellent effects.
• the ant repellence effect achieved with the compositions of Examples 2 to 4 and 7 is comparable to the effect achieved with a commercial product containing the insecticide NMDA, use of which is critical for health and safety reasons.
• compositions as shown in Examples 1 to 7 but without cationic surfactant did not show a long- lasting (> 1 h) ant or cockroach repelling effect. In contrast, the compositions of the invention were able to provide > 85% repellency after 8 hours. In addition, compositions as shown in Examples 1 to 7 but without cationic surfactant and even higher amounts of polymer did also not provide a long-lasting insect repellency.
• compositions of the present invention impart superior and long lasting insect repellent effect, which makes frequent use and/or the use of harsh chemicals such as insecticides unnecessary. Additionally, the cleaning compositions of the invention have excellent cleaning properties and provide for a non-sticky and shiny appearance of the cleaned surface.
