EXTERNAL WOUND-HEALING AGENT, AND EXTERNAL WOUND-HEALING MATERIAL
An external wound-healing agent includes, as an active ingredient, at least one compound of a glycerol alkyl ester represented by Formula (I) or a diglycerol alkyl ester represented by Formula (II).
1 . An external wound-healing agent comprising, as an active ingredient,
at least one compound of a glycerol alkyl ester or a diglycerol alkyl ester,
the glycerol alkyl ester represented by the following Formula (I):
wherein, in Formula (I), each of R 1 , R 2 , and R 3 independently represents a hydrogen atom or an acyl group having from 12 to 22 carbon atoms, and at least one of R 1 , R 2 , or R 3 is an acyl group having from 12 to 22 carbon atoms,
the diglycerol alkyl ester represented by the following Formula (II):
wherein, in Formula (II), each of R 4 , R 5 , R 6 , and R 7 independently represents a hydrogen atom or an acyl group having from 12 to 22 carbon atoms, and at least one of R 4 , R 5 , R 6 , or R 7 is an acyl group having from 12 to 22 carbon atoms.
2 . The external wound-healing agent according to claim 1 , wherein the glycerol alkyl ester is at least one of glycerol palmitate or glycerol stearate, and the diglycerol alkyl ester is at least one of diglycerol palmitate or diglycerol stearate.
3 . An external wound-healing material comprising:
a fiber aggregate; or
a film,
the fiber aggregate or the film each comprising:
a thermoplastic resin; and
at least one compound of a glycerol alkyl ester or a diglycerol alkyl ester,
the glycerol alkyl ester represented by the following Formula (I):
wherein, in Formula (I), each of R 1 , R 2 , and R 3 independently represents a hydrogen atom or an acyl group having from 12 to 22 carbon atoms, and at least one of R 1 , R 2 , or R 3 is an acyl group having from 12 to 22 carbon atoms,
the diglycerol alkyl ester represented by the following Formula (II):
wherein, in Formula (II), each of R 4 , R 5 , R 6 , and R 7 independently represents a hydrogen atom or an acyl group having from 12 to 22 carbon atoms, and at least one of R 4 , R 5 , R 6 , or R 7 is an acyl group having from 12 to 22 carbon atoms.
4 . The external wound-healing material according to claim 3 , wherein the glycerol alkyl ester is at least one of glycerol palmitate or glycerol stearate, and the diglycerol alkyl ester is at least one of diglycerol palmitate or diglycerol stearate.
5 . The external wound-healing material according to claim 3 , wherein the thermoplastic resin is at least one resin selected from the group consisting of olefin resins, urethane resins, amide resins, ester resins, acrylic resins, styrene resins, and carbonate resins.
6 . The external wound-healing material according to claim 5 , wherein the thermoplastic resin is an olefin resin.
