A HYBRID OF AN UNSATURATED FATTY ACID WITH A LAYERED METAL HYDROXIDE, A PROCESS FOR THE PREPARATION THEREOF, AND FUNCTIONAL FOODS AND A DERMAL EXTERNAL PREPARATION COMPRISING THE SAME

摘要

A hybrid with layered metal hydroxide is provided to increase the stability of unsaturated fatty acid, easily formulate, and efficiently apply the unsaturated fatty acid into the skin. A hybrid of an undsaturated fatty acid and layered metal hydroxide is obtained by introduction of unsaturated fatty acid between the layers of layered metal hydroxide and hybridization. The metal double layer hydroxide is a compound of the chemical formula 1([M(II)1-xM(III)x(OH)2]X+(An-)X/n.yH2O) or formula 2([M(II)(OH)x'](A)(2-x')/n.yH2O). The hybrid is reformed with tocopherol, lauric acid, tetra-ethyl orthosilicate (TEOS), glyceryl monostearate (GMS) or dimethicone. The method for manufacturing the hybrid comprises: a step of producing essential fatty acid and bivalent metal salt solution; and a step of adding base to adjust to pH 4-8 and collecting the precipitate.
