Abstract:
The present invention provides a surfactant composition containing a polyglycerol alkyl ether which is capable of exhibiting a high emulsification performance for silicone oils compounded in cosmetics, detergents, etc., by using a natural alcohol derived from oils and fats as a raw material thereof, a process for producing the surfactant composition in an effective manner, and a use of the surfactant composition. The present invention relates to [1] a surfactant composition including a specific polyglycerol monoalkyl ether (1) and a specific polyglycerol dialkyl ether (2), a mass ratio of [(1)/(2)] being from 65/35 to 75/25; [2] a process for producing the surfactant composition; [3] an emulsifier composition including the surfactant composition; and [4] a detergent composition including the surfactant composition.
Abstract:
The invention relates to a method for producing polyether polyols by means of a DMC-catalyzed alkylene oxide addition to starter compounds containing acidic sulfuric acid salts, to the use thereof for producing polyurethanes, and to polyurethanes containing the polyether polyols according to the invention.
Abstract:

Abstract:
A process for glycerol etherification, including a recycle of glycerol and/or mono-ether, to produce glycerol alkyl ethers with low amount of mono-ether by reacting glycerol and olefinic hydrocarbon, and/or the corresponding aldehydes, ketones and alcohols, having 2 to 10 carbon atoms in the presence of homogeneous acid catalyst with hindered formation of olefin oligomers comprising of two essential steps: reaction step (1) neutralization and salt removal step (2).
