Abstract: A detergent composition may include 10 to 30% by weight of octylphenol ethoxylate, 0.1 to 5% by weight of 2-ethylhexyl alcohol ethoxylate, 0.1 to 5% by weight of ethylene oxide-propylene oxide block copolymer, and the balance of water, based on a total 100% by weight of the composition. The detergent composition may have an excellent virus removal effect in which more than 99.99% of corona virus is removed in 30 seconds. At the same time, provided is a safe detergent composition which has selective properties of not killing various bacteria, and satisfies skin hypoallergenic properties. In addition, the detergent composition is used for various purposes, such as removal of corona virus, removal of oil stains, removal of kitchen dirt, bathroom cleaning, cleaning of mechanical equipment and parts, and removal of oil stains on clothes, and exhibits excellent cleaning ability.

Abstract: Disclosed herein are a perfluoroalkyleneoxy group-substituted phenylethylsilane compound and a polymer thereof. The perfluoroalkyleneoxy group-substituted phenylethylsilane compound represented by Formula 1 has excellent thermal and chemical stability to be solution-processed in a monomer state, and the polymer prepared by thermally crosslinking the compound has a high resistance to organic solvents. Moreover, since an insulating layer prepared by applying the same shows improved thermal and physical properties, it is possible to manufacture organic thin-film transistors having a high on/off ratio in a simple process such as a photolithography for a large-size substrate: wherein R1, R2, R3, Z1, Z2, Z3, and n are the same as defined in the detailed description of the invention.
