The present invention relates to a composition comprising, as an active ingredient for drug delivery into a tissue having a tight junction, a triolein emulsion in an internal water phase / oil phase / external water phase (water / oil / water; W / O / W)-type structure in which an oil droplet includes triolein and a water droplet is enclosed inside the oil droplet, and to a preparation method therefor. The triolein emulsion in the W / O / W-type structure according to the present invention has water-phase droplets enclosed inside oil-phase droplets while exhibiting that the triolein retains the activity of opening BBB. In addition, the emulsion includes a surfactant and thus has excellent safety. Allowing a liposoluble drug to be further enclosed in the oil-phase droplets, the emulsion can used as a composite formulation and thus more effectively deliver the drug into tissues having tight junctions such as the brain, the testis, the retina, and the like.

The invention relates to an oil agent for improving morphological stability of textile. The oil agent comprises the following ingredients, by weight, 30-40 parts of oxirane polyether, 20-30 parts of sodium dodecylphosphate ester, 18-25 parts of alkylether potassium sulfate, 10-15 parts of glyceryl trioleate, 8-12 parts of a succinic acid osmotic agent, 3-8 parts of an emulsifier OP-10 and 4-7 parts of alkyl diethanolamine. By the use of the oil agent for improving morphological stability of textile, the improved textile has good fiber crimp performance, strong frictional force and cohesive force, strong deformation-recovery force and good morphological stability, and the textile will not deform or contract.

The invention belongs to the field of nanometer materials, and specifically discloses a magnetic composite nanometer material, a preparation method and an application thereof. The raw materials for the preparation of the magnetic composite nanomaterial include Fe 3 o 4 Ferromagnetic nanoparticles, cellulose acetate and glyceryl trioleate, by modifying the surface of magnetic nanoparticles of cellulose acetate, and fixing glyceryl trioleate in the microporous structure of cellulose acetate; by controlling the ratio of solvent addition and temperature and other conditions, magnetic composite nanoparticles can be prepared.
