Abstract
Abstract A novel nonionic compound, a polyoxypropylene polyoxyethylene addition ether of a higher branched primary saturated alcohol is provided. This nonionic compound is suitable for use, as a solubilizing agent, in a high concentration solution of a lower alcohol in water, for example, in cosmetics such as a transparent liquid hair preparation, a hair cologne, an after-shaving lotion, a skin lotion and the like.
