Nanometer emulsion composition with effect of improving skin barrier and application of nanometer emulsion composition

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of cosmetics or medicines, in particular to a nanoemulsion composition with improved skin barrier and its application. Background technique [0002] Various emulsified compositions have been widely used in the field of cosmetics or pharmaceuticals, but most of their emulsified compositions are cream-like or cloudy emulsions with high viscosity; in order to improve appearance and reduce viscosity, some cosmetics add traditional opacifiers (such as styrene / acrylic acid (ester) copolymer) achieves a milky white appearance, but these substances belong to plastic particles, are not easy to degrade, have adverse effects on the environment and bioaccumulation, and do not have the moisturizing and moisturizing effects of emulsified formulas; There are other methods to reduce the emulsified particle size. The commonly used methods are D-phase emulsification, coagulation method or PIT emulsification, which have certai...

Problems solved by technology

[0002] Various emulsified compositions have been widely used in the field of cosmetics or pharmaceuticals, but most of their emulsified compositions are creamy or cloudy emulsions with high viscosity ;In order to improve the appearance and reduce the viscosity, some cosmetics achieve the milky white appearance of the material body by adding traditional sunscreens (such as styrene / acrylic acid (ester) copolymers), but these substances belong to plastic particles, are not easy to degrade, and are harmful to the environment and bioaccumulation It has adverse effects, and does not have the moisturizing and moisturizing effects of emulsified formulas; other methods that can reduce the emulsified particle size, the commonly used methods are D-phase emulsification, coagulation method or PIT emulsification, which has a great influence on the emulsifier selection of the formula , the amount of emulsifier, the type and content of oil, and the process have certain requirements; the increase in emulsifier content may lead to an increase in the irritation of the formula; and due to stability reasons, the oil content cannot be too high, resulting in insufficient moisture; oil The types are limited and cannot meet the skin feeling requirements required for emulsified formulations; these characteristics limit its application in cosmetics or pharmaceuticals for skin, scalp and hair, etc.
