    Abstract: PROBLEM TO BE SOLVED: To obtain transparent and stable oil emulsion, particularly for use in cosmetics or medicines, in which there is no problem from the viewpoint of toxicology by including an alkylpolyglycoside represented by a specific formula, oil and water at specific ratio. SOLUTION: This oil emulsion which is transparent and stable and has improved bubble forming characteristics is composed of an alkylpolyglycoside represented by the formula R-O-(Z)n -H [wherein R: an alkyl group, -(Z)n -H: a polyglycosyl group, Z: a glycosyl group, n: average value 1-5], oil and water, and weight ratio of the alkylpolyglycoside to oil is in the range of (1.5:1)-(15:1). The polyglycosyl group may be an oligomer or monoglycosyl group. Sugar components which can be used as the alkylglycosyl group are, for example, glucose, fructose, mannose, galactose.

    Abstract: PURPOSE: To provide a petroleum emulsion decomposing agent which not only well decomposes a water-in-oil emulsion but gives the decomposed water containing residual oil as little as possible, and can be easily produced. CONSTITUTION: This petroleum emulsion decomposing agent is based on an alkoxylated polyethyleneimine and is obtd. by alkoxylation of polyethylene imine having 2500 to 35000 mol.wt. Mw in 5 to 40 mol of propylene oxide and 5 to 40 mol. ethylene oxide per unit ethyleneimine in the polyethyleneimine, and the agent is used at 10 to 130 deg.C for demulsification of a petroleum emulsion.
