Abstract
A liquid and readily flowable composition includes (a) a room-temperature-solid solute, such as a nonionic surfactant, preferably having a hydrophile-lipophile balance from about 11.1 to about 18.4, a (ii) C8-C14 fatty acid, or combinations thereof; (b) an alkoxylated fatty alkanolamide; and (c) water, if needed. The alkoxylated fatty alkanolamide, which is substantially liquid at room temperature, solvates the solid solute to form a homogeneous composition which is liquid and readily flowable at room temperature. The select classes of nonionic surfactants include polyalkylene oxide carboxylic acid esters, ethoxylated fatty alcohols, poloxamers, alkyl polysaccharides, or combinations thereof. Useful alkoxylated fatty alkanolamides include propoxylated fatty ethanolamides.
