W1/O/W2-TYPE DOUBLE EMULSION DRESSING AND METHOD FOR PRODUCTION THEREOF

摘要

Disclosed is a W1/O/W2-type double emulsion dressing which comprises a polyglycerin condensed ricinoleate having an degree of esterification ranging from 10 to 30% inclusive and an degree of condensation of ricinoleic acid ranging from 5 to 8 inclusive and has a viscosity ranging from 1,000 to 300,000 mPa·s inclusive. Also disclosed is a method for production of a W1/O/W2-type double emulsion dressing comprising the steps of mixing 90 to 10 parts by mass of an aqueous phase (W1) with 10 to 90 parts by mass of an oily phase (O) to prepare a W1/O-type emulsion and mixing 100 parts by mass of the W1/O-type emulsion with 25 to 150 parts by mass of an aqueous phase (W2) to prepare the desired W1/O/W2-type double emulsion dressing, wherein a polyglycerin condensed ricinoleate having an degree of esterification ranging from 10 to 30% inclusive and an degree of condensation of ricinoleic acid ranging from 5 to 8 inclusive is contained in an amount of 0.01 to 5% by mass based on the total amount of the dressing. The dressing is excellent in storage stability.
