Description
Technical field
The present invention relates to a kind of disinfection emulsion and preparation method thereof more particularly to a kind of nanometer composite skin disinfection emulsion and
Preparation method.
Background technique
Skin and mucous membrane are the effective barriers that human body resists that microorganism invades profit tissue, but have micro- life abundant on its surface
Object.In daily life, by opponent and mucocutaneous disinfection, enteric infectious disease, skin pyesis and uropoiesis can be prevented
The infection of reproductive system;In health system, the important leverage that skin degerming is modern medical service, and control hospital are carried out
Infect one of most important, most easy-to-use measure.
Currently used skin and mucous membrane disinfection agent huge number, but more or less defect is suffered from, as quaternary ammonium salt is anti-
Bacterium spectrum is narrow, and sterilizing ability is weak;Ethyl alcohol is big to skin and mucous membrane irritation;The Iodophor bactericidal effect duration is shorter;Chlorhexidine acetate
Class is also easy to produce antibody-resistant bacterium.Traditional disinfection agent is difficult to comply fully with the needs of clinical departments medical staff's hand disinfection, to make
At cross-infection.Therefore, it is necessary to find New raxa, novel form or new compound prescription, to reach ideal skin degerming effect.
Summary of the invention
The object of the present invention is to provide a kind of nanometer composite skin disinfection emulsion and preparation method thereof, the skin disinfection emulsions
By double-chain quaternary ammonium salt compound and inorganic nano antiseptic substance compatibility, and emulsifier and aloe extract is added, had both played
