Patent number: 5434190Abstract: N-monosubstituted neoalkanamides of 11 to 14 carbon atoms wherein the substituent on the amide nitrogen is cyclic (aromatic or cycloaliphatic, such as aryl or cycloalkyl) and of at least five carbon atoms, have been discovered to be insect repellent, providing that any aromatic substituent is unsubstituted at the ortho position and that when the neoalkanoyl moiety is pivaloyl the total number of carbon atoms in the N-cyclic neoalkanamide is at least 12. Such neoalkanamides are useful as repellents against cockroaches, including American, German and Oriental cockroaches, and are also effective against mosquitoes (both Anopheles and Aedes), black flies and carpenter ants, and to some extent against deer ticks. They may be applied to areas, locations and items which are desirably to be kept free of such insects, with applications being direct or of solutions or emulsions thereof, preferably by spraying, or in detergent compositions or other products to be applied to such areas, etc.Type: GrantFiled: October 11, 1994Date of Patent: July 18, 1995Assignee: Colgate-Palmolive Co.Inventor: Robert J.

Patent number: 5143900Abstract: Perfumes containing normal perfuming components, such as essential oils, esters, ethers, aldehydes, alcohols, hydrocarbons, ketones and lactones, have the fragrances thereof desirably altered, and often significantly strenghtened, by incorporation with them, as another perfuming component, of a N-lower alkyl neoalkanamide, such as ethyl neodecanamide, or a mixture of such neoalkanamides. It has been found that the neoalkanamides are of desirable fragrances, are stable, even in alkaline media, such as built detergent compositions, maintaining their fragrance notes in the perfumes and in perfumed products during comparatively lengthy storage periods, and are significantly substantive to surfaces contacted by them, even when such contact is made in relatively dilute media, such as aqueous wash water, as when ther neoalkanamide (preferably methyl- or ethyl neodecanamide) is a component of a perfume that has been employed to perfume a detergent composition.Type: GrantFiled: March 6, 1991Date of Patent: September 1, 1992Assignee: Colgate-Palmolive CompanyInventors: Robert J.
