Abstract

The present invention relates to include washing-free antibacterial hand sanitizer of Nano-Zinc antiseptic and preparation method thereof.Washing-free antibacterial hand sanitizer of the invention has outstanding bactericidal effect and low-down skin irritation, can be widely applied to the antibacterial of skin and body surface in daily life, antibacterial, sterilization.

Description

Washing-free antibacterial hand sanitizer and preparation method thereof
Technical field
The invention belongs to sterile products technical field, and in particular to a kind of washing-free antibacterial hand sanitizer, and preparation method thereof.
Background technology
Antibacterial includes antibacterial, sterilizing, sterilized, mould proof, anti-corrosion.Bacterium is killed using chemically or physically method or is prevented thin The process of bacteria growing breeding is the general name of antibacterial.Antiseptic is can to make certain micro-organisms within a certain period of time(Bacterium, fungi, Saccharomycete, algae and virus etc.)Growth or breeding be maintained at necessary chemical substance below horizontal.
Antiseptic is broadly divided into organic antibacterial agent, inorganic antiseptic and natural antibacterial agent.Organic antibacterial agent anti-microbial property is high, Sterilization speed is fast, but to environment and human body is harmful and working life is short, poor heat resistance;Natural antibacterial agent antimicrobial efficiency is high, peace Atoxic, but processing difficulties, poor heat resistance.Inorganic antiseptic is because its effective antibacterial phase is long, the good, has a broad antifungal spectrum of heat resistance etc. Feature turns into the class antiseptic being most widely used.
In inorganic antiseptic, at most, purposes is most for the inorganic salts of metal ion or the inorganic antiseptic kind of complex compound Extensively, at most, wherein antibiotic property size is ordered as yield:Hg>Ag>Cd>Cu>Zn>Fe>Ni etc., but be with antibiotic property only Inadequate, also requiring that it can not be damaged to human body, the metal such as Hg, Cd, Pb also has antibacterial ability, but harmful. The security of metal ion is ordered as:Ag>Co>Ni>Al>Zn>Cu=Fe>Mn>Sn>Ba>Mg>Ca, so with regard to security and antibacterial Property the common result for considering, next to that Cu systems and Zn systems, therefore these three with inorganic compound as carrier with Ag ions preferably Inorganic antiseptic is obtained a wide range of applications.But, Cu ions carry color because of itself, can influence the expressive force of product;Silver Because its easy oxidation discoloration, it is expensive, easily reunite the problems such as, be restricted using scope.
Metallic zinc is the 1/1000 of argent due to the antibacterial ability of itself, causes most of research institutions and manufacturer All energy is concentrated in the modified research and development of Ag and Nano Silver to improve it as the performance of antiseptic, so as to have ignored zinc conduct The plurality of advantages of antiseptic, studies seldom it.In fact, Nano-Zinc antiseptic can overcome nano silver antimicrobials actually should Many defects in, such as easily oxidation, blackening, expensive, difficult dispersion, and possess significant antibacterial effect, significantly Extend antibacterial ageing, especially can relatively easily be scattered in corresponding product, such as plastics, textile fabric, slurry, Waterborne liquid, oil soluble liquid, greatly extend range of application.Therefore, research and development Nano-Zinc antiseptic can be greatly Meet social desirability.
Within past a very long time, sanitary washing is used as commonly using soap, perfumed soap in people's daily life Articles for use.Though soap, perfumed soap easily slide when in use with good dirt-removing power, meeting water and high temperature can soften and nature Consumption, soap, perfumed soap can make dry skin in alkalescence after cleaning, lack gloss, and soap, perfumed soap are sterilized in cleaning process Effect is limited, and is bound to be infected with dirt on hand and bacterium after use, produces secondary pollution, and washing-free antibacterial hand sanitizer With antibacterial, skin care, using and effect easy to clean etc..Recently as growth in the living standard, people's consumption idea Change therewith, demand higher is it is also proposed to hygiene, so that washing-free antibacterial hand sanitizer substitutes conventional soap, perfumed soap, As widely used hand-washing article, work, family and public arena are applied to.
The major antibacterial composition of current anti-bacterial hand lotion on the market is with parachlorometaxylenol, gluconic acid chlorhexidine, iodine Based on class, alcohols, quaternary ammonium salt and its complex antimicrobials, these antiseptics are all easily caused the resistance to the action of a drug and mistake to varying degrees The generation of quick reaction, and there is the defects such as action time is short, bactericidal range is narrow.
The content of the invention
To solve above-mentioned the problems of washing-free antibacterial hand sanitizer in the prior art, the present invention proposes a kind of including receiving Washing-free antibacterial hand sanitizer of rice zinc antiseptic and preparation method thereof, washing-free antibacterial hand sanitizer of the invention has outstanding sterilized effect Fruit and low-down skin irritation, can be widely applied to the antibacterial of skin and body surface in daily life, antibacterial, sterilization.
In an aspect, the present invention relates to a kind of washing-free antibacterial hand sanitizer, it is grouped into by each group of following mass fraction: The mass parts of Nano-Zinc antiseptic 0.5 ~ 3, the mass parts of ethanol 20 ~ 65, the mass parts of isopropanol 0.5 ~ 10, the mass parts of propane diols 0.1 ~ 5, The mass parts of deionized water 10 ~ 90, the mass parts of essence 0 ~ 0.5.
In a preferred embodiment, the content of the essence is not zero.
In a preferred embodiment, described washing-free antibacterial hand sanitizer is grouped into by each group of following mass fraction:Receive The mass parts of rice zinc antiseptic 1, the mass parts of ethanol 60, the mass parts of isopropanol 5, the mass parts of propane diols 0.3, the mass of deionized water 33 Part, the mass parts of essence 0.01.
In another aspect, the present invention relates to the preparation method of the washing-free antibacterial hand sanitizer, comprise the following steps:
(1)The Nano-Zinc antiseptic of formula rate amount is added in reactor, the deionized water for being subsequently added 1/3 formula ratio is stirred Mix 3-10min;Preferably 4-6min;More preferably 5min;
(2)The ethanol of formula ratio is added while stirring, it is extremely well mixed;
(3)Isopropanol, the propane diols of formula ratio are sequentially added under stirring, it is extremely well mixed;
(4)Add the deionized water of surplus while stirring, stirring 5-15min is to well mixed;Preferably 7-12min;It is more excellent Elect 10min as;
(5)It is added dropwise to essence under stirring, and continues stirring to well mixed.
In various embodiments, isopropanol can be replaced normal propyl alcohol or polyethylene glycol.
In various embodiments, propane diols can be replaced glycerine, hyaluronic acid, amino acid or water-soluble Jojoba Oil.
Wherein, ethanol has the disposable effect of volatilization concurrently as primary solvent, and isopropanol, propane diols play the work of volatilization hydrotropy With, and smell is thin.Can be reduced in the case where disposable performance is not changed using three kinds of components as described above and be given out Smell.
