Abstract
Stable and homogeneous gel is obtained by forming a solution of a hydrophilic sucrose fatty-acid ester and a hydrophilic liquid polyhydric alcohol and incorporating oil into the resulting solution. Thus-prepared gel is useful either per se or for producing stable aqueous emulsions by admixing water therewith. Stable and homogeneous gel is also obtained by forming a solution of hydrophilic sucrose fatty-acid ester, hydrophilic liquid polyhydric alcohol and lipophilic polyhydric alcohol fatty-acid ester and adding oil to the thus-obtained solution. Such gel likewise yields a stable aqueous emulsion when admixed with water. Neither the noted homogenous gel nor the noted stable emulsion is produced from the specified constituents when admixed in a different order from that specified.
