  • Patent number: 5610194
    Abstract: Insect repellent compositions are provided comprising mixtures of:(a) from about 5 to about 95%, by weight, of an N-alkyl neoalkanamide having the formula: ##STR1## wherein R.sub.1 R.sub.2, and R.sub.3 are alkyl groups and the sum of the carbon atoms therein is from 6 to 12, and wherein R.sub.4 is either a hydrogen atom or an alkyl group having one to two carbon atoms, and wherein R.sub.5 is methyl, ethyl, or propyl; and(b) from about 5 to about 95%, by weight, of N,N-diethyl-meta-toluamide (DEET).Preferred repellent composition comprise mixtures of N-methyl neodecanamide (MNDA) and DEET which provide synergistic repellency effects against a variety of insects including cockroaches, silverfish, mosquitoes, flies and ants. The repellent compositions may be applied directly to surfaces to be treated or they may be incorporated in detergent compositions such as laundry detergents, floor and wall cleaners, rug cleaners and shampoos, hair shampoos and liquid and bar soaps.

  • Patent number: 5434190
    Abstract: 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.

  • Patent number: 5434189
    Abstract: N-lower alkyl neoalkanamides of 1 to 2 carbon atoms in the lower alkyl thereof, and of 12 to 14 carbon atoms in the noalkanoyl group, e.g., N-methyl- and N-ethyl neotridecanamides, are new compounds which have insect repellent properties, being especially effective against cockroaches, e.g., the German and American cockroaches. However, they are also useful as repellents for other insects, including mosquitoes, moths, flies, fleas, ants, and lice. Additionally, they may repel arachnids, such as spiders, ticks and mites. The new neoalkanamides may be synthesized easily, as by reacting a primary lower alkyl amine with a neoalkanoyl halide, e.g., by reacting methyl amine or ethyl amine with neotridecanoyl chloride.

  • Patent number: 5143900
    Abstract: 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.

  • Patent number: 4715862
    Abstract: A wash cycle fabric conditioning composition, which makes laundry washed in an automatic washing machine and dried in an automatic laundry dryer resistant to the accumulation of static charges thereon, and which may be in particulate, liquid, or other suitable form, comprises an antistatic N-higher alkyl neoalkanamide or an antistatic N-higher alkenyl neoalkanamide, or a mixture thereof, and a detergent builder, such as a water soluble builder salt or a zeolite, or a mixture thereof, as a carrier, or an aqueous medium containing a nonionic surface active agent. Specifically preferred neoalkanamides of the type described are N-higher alkyl neodecanamides, such as tallowalkyl neodecanamide. In some instances, bentonite may be included in the particulate compositions to soften the fabrics that are washed, and tertiary amines may be formulated into the liquid compositions to increase fabric softening action.
