US 2004/0166078 A1 · Oil-in-water emulsions and process for producing the same

Abstract

A process for the preparation of an o/w emulsion, which comprises mixing together a high molecular compound carrying at least on side chains thereof groups represented by the following formula (1): —(OX)n-E2-R (1) wherein n “X”s may be the same or different and each independently represents a linear or branched, divalent, saturated C1-6 hydrocarbon group, n stands for a number of from 5 to 300, E2 represents an ether bond or an oxycarbonyl group (—OCO— or —COO—), and R represents a linear or branched, C4-30 alkyl group which may be substituted by hydroxyl group(s), an aqueous solution of a water-soluble polyol, and a hydrophobic compound, and diluting a resulting mixture with water, and the o/w emulsion obtained by the preparation process. The emulsion according to the present invention is excellent in touch feeling to the skin and is good in stability.
