The invention discloses a nanometer
emulsion composition with an effect of improving the
skin barrier and application of the nanometer
emulsion composition. The nanometer
emulsion composition comprises the following ingredients (A) 0.005 to 2.5 percent of an emulsifier, (B) 0.01 to 5 percent of higher
alcohol, (C) 0.02 to 60 percent of
grease, and (D) 3 to 30 percent of polyhydric
alcohol or
polysaccharide, wherein the content of the ingredient (C) is greater than or equal to the sum of the contents of the ingredient (A) and the ingredient (B). By selecting the low-content and specific-kind emulsifier to be compounded with the specific contents of the higher
alcohol, the
grease and the polyhydric alcohol or the
polysaccharide and controlling the content of the
grease to be greater than thesum of the weight of the emulsifier and the compounding weight of the emulsifier, the nanometer emulsion composition with the average particle
diameter being smaller than or equal to 200 nm is prepared. The nanometer emulsion composition has low
viscosity, so that a convenient use feeling is realized; the influence by different kinds of grease is avoided; the stability is high; a good transparenteffect and soft and
moist skin feelings like cream are realized; the
skin moisture preserving degree, the moisturizing degree, the smoothness degree and the softness can be improved; and the consumption of the emulsifier is reduced, so that the
skin tolerance can be increased.
