Abstract: The present invention provides a composition for preventing adhesion of air-borne fine particles, which contains a 2-(meth)acryloyloxyalkyl phosphorylcholine-(meth)acrylic acid alkyl ester copolymer as an antistatic agent, and which is not decreased in the effect of preventing adhesion of air-borne fine particles even if a sufficient amount of an oil component is blended therein. The present invention is characterized by containing (A) 2-(meth)acryloyloxyalkyl phosphorylcholine-(meth)acrylic acid alkyl ester copolymer, (B) a di-long-chain cationic surfactant represented by formula (I) (wherein each R1 independently represents and alkyl group having 12-22 carbon atoms and 0-3 double bonds; each R2 independently represents an alkyl group having 1-3 carbon atoms and no double bond; and Y represents a halogen atom, a methosulfate or a methophosphate), and (C) one or more oil components selected from among hydrocarbon oils, ester oils and silicone oils.

Abstract: The purpose of the present invention is to provide: a virus inactivating agent that exhibits an effect at an amount that does not cause skin irritation; and an external skin preparation composition containing said virus inactivating agent. The present invention relates to: a virus inactivating agent containing, as an effective component thereof, at least one selected from mint oil, eucalyptus oil, rosemary oil, sage oil, tea tree oil, shell ginger oil, peppermint oil, lemongrass oil, cajeputi oil, niaouli cineole oil, lime oil, lemon oil, lemon verbena oil, St. John's wort oil, ravintsara oil, rosewood oil, Melissa/lemon balm oil, myrrh oil, mandarin oil, vetiver oil, frankincense oil, citronella oil, cardamom oil, Angelica oil, and cationized starch; and an external skin preparation composition containing the same.

Abstract: An objective of the present invention is to provide a gel-type skin preparation for external use into which a di-chain cationic surfactant can be stably blended without precipitation over time and which can be spread topically on skin. The gel preparation according to the present invention comprises (a) a di-chain cationic surfactant having a specific structure, (b) an oil in which component (a) is soluble, (c) a lower alcohol, (d) a water-soluble thickener, and (e) water.
