Abstract
The present invention provides a novel non-lamellar liquid crystal-forming composition. An aspect of the present invention is a non-lamellar liquid crystal-forming composition comprising a fatty acid ester and a phospholipid. The fatty acid ester has a hydrophilic group having one hydroxyl group or a salt thereof, and the fatty acid ester is a fatty acid ester having none of the structures represented by General Formulas (A) to (D) (where m is independently 1 or 2; a, b, c, and d are each independently a binding site to a hydrophilic group; n is 0, 1 or 2; and the wavy lines each independently mean an E-isomer or a Z-isomer).
Claims22
A non-lamellar liquid crystal-forming composition comprising:
- a fatty acid ester;
- and
- a phospholipid, wherein
- the fatty acid ester has a hydrophilic group having one hydroxyl group or a salt thereof, and
- the fatty acid ester is a fatty acid ester having none of structures represented by General Formulas (A) to (D):
- in General Formulas (A) to (D), m is independently 1 or 2;
- a, b, c, and d are each independently a binding site to a hydrophilic group;
- independently means a single bond or a double bond;
- in General Formula (A), n is 0, 1, or 2;
- and in General Formulas (B), (C), and (D), a wavy line independently means an E-isomer or a Z-isomer.
A compound represented by Formula (X′) or a salt thereof:
- in General Formula (X′), R1 is a structure derived from propylene glycol, butylene glycol, isoprene glycol, diethylene glycol, or isosorbide.
A compound represented by Formula (X), (Y), or (Z):
- or a salt thereof.
