  • Patent number: 5346639
    Abstract: A spray shampoo composition is formulated having a viscosity less than 40 CPS but with an actives concentration of 8% to 15%. This is accomplished by combining anionic detergents such as ammonium laurel sulfate and ammonium laureth sulfate, along with amphoteric surfactants such as cocamidopropyl betaine, along with nonionic surfactants such as cocamide DEA and lauramide DEA, wherein the detergent is substantially free from neutral salt thixatropes. This provides a highly concentrated detergent which has a viscosity which permits atomization of the detergent when dispensed from a finger pump sprayer.
