Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
58 words
A process for producing a W/O/W type multiple emulsion which comprises adding, to water or an aqueous phase, an oil phase to which 1.0 to 10% of monoerucin or dierucin is added, mixing them to form an O/W emulsion, stirring the emulsion to effect phase inversion, adding the resulting W/O emulsion to an aqueous phase, and stirring them.
Claim 2
Dependent Claim
58 words
A process for producing a W/O/W type multiple emulsion which comprises adding, to water or an aqueous phase, an oil phase to which 1.0 to 10% of monoerucin or dierucin is added, mixing them to form an O/W emulsion, stirring the emulsion to effect phase inversion, adding the resulting W/O emulsion to an aqueous phase, and stirring them.
Claim 3
Dependent Claim
46 words
A process for producing a W/O/W type multiple emulsion which comprises adding water or an aqueous phase to an oil phase to which 1.0 to 10% of monoerucin or dierucin is added, mixing them, adding the resulting W/O emulsion to an aqueous phase, and stirring them.
Claim 4
Dependent Claim
46 words
A process for producing a W/O/W type multiple emulsion which comprises adding water or an aqueous phase to an oil phase to which 1.0 to 10% of monoerucin or dierucin is added, mixing them, adding the resulting W/O emulsion to an aqueous phase, and stirring them.
Claim 5
Dependent Claim
52 words
A process for producing a W/O/W type multiple emulsion which comprises adding water or an aqueous phase to an oil phase to which 1.0 to 10% of monoerucin or dierucin is added, mixing them to obtain a W/O emulsion, and stirring further the W/O emulsion to form a W/O/W type multiple emulsion.
Claim 6
Dependent Claim
52 words
A process for producing a W/O/W type multiple emulsion which comprises adding water or an aqueous phase to an oil phase to which 1.0 to 10% of monoerucin or dierucin is added, mixing them to obtain a W/O emulsion, and stirring further the W/O emulsion to form a W/O/W type multiple emulsion.
