personal cleaning products and mixtures of surfactants useful in them are revealed. the cleaning products comprise a primary anionic surfactant, a saturated c8-c14 alkyl n, n-dialkylamide, and water. cleaning products have good foaming properties and improved viscosity profiles compared to cleaning products that depend on alkanolamides or betaines as the secondary surfactant. the saturated n, n-dialkylamides of c8-c14 alkyls are transparent liquids like water that solubilize components of cleaning products, including high levels of fragrances, and can be formulated easily without heating for any level of active agents up to 100%. importantly, mixtures of surfactants increase viscosity with less salt added compared to mixtures based on alkanolamide or betaine, even with more problematic anionic surfactants. the moisturizing cleaning products disclosed in this document have an excellent character of rapid foaming, foam volume and foam sensation and provide an exquisite after-feel similar to that of lotions. personal cleansing products include, among other products, shampoos, body soaps, face cleansers, shower gels, liquid soaps, hand soaps, baby liquid cleansers, pet shampoos, and bubble bath products. the n, n-dialkylamide greases are also valuable for the formulation of oil-in-water emulsions with good stability.são revelados produtos de limpeza pessoal e misturas de tensoativos úteis nos mesmos. os produtos de limpeza compreendem um tensoativo aniônico primário, uma n,n-dialquilamida de alquila c8-c14 saturada, e água. os produtos de limpeza possuem boas propriedades de formação de espuma e perfis de aumento de viscosidade aprimorados em comparação com produtos de limpeza que dependem de alcanolamidas ou betaínas como o tensoativo secundário. as n,n-dialquilamidas de alquilas c8-c14 saturadas são líquidos transparentes como água que solubilizam componentes de produtos de limpeza, incluindo altos níveis de fragrâncias, e podem ser formuladas facilmente sem aquecimen
