Description

A kind of air freshener and preparation method thereof
Technical field
The present invention relates to daily chemical product technical field more particularly to a kind of air fresheners.
Background technique
Air freshener products in daily life using more and more extensive, the air quality in automobile can be improved, Increase the pleasant feeling of people.Current air freshener has following several: solid air freshening agent, volatile liquid are with fresh air Agent, aerosol type air freshener and aerial fog type air freshener etc..
Solid air freshening agent appears in the external beginning of the seventies earliest, is mainly used for car, household bedroom or parlor, guest Shop restaurant and other places of public amusement.In recent years, with the raising of China's lives of the people level, domestic market demand amount increases Add quickly.The basic preparation principle of the product is by essence, deodorant and disinfection sanitizer and water, thickener, preservative, emulsification The mixing of the components such as agent, water and thickener form solid colloidal object, and essence, deodorant and disinfection sanitizer are contained it by this jelly In, essence, deodorant and disinfection sanitizer are slowly dispersed into air later, so that reaching makes air fragrant, pure and fresh mesh 's.However, air freshener quality currently on the market is irregular.Early in 2005, european consumers' organization was just to 76 kinds Household air freshener is tested, as a result, it has been found that containing well-known noxious material in a variety of air fresheners: such as Acetaldehyde or phenylethylene stimulation respiratory tract induce the substance that allergy even has potential carcinogenicity, even go back in another kind of product Contain formaldehyde and benzene.
The chemical substance of a part would generally be added among existing major part air freshener, these chemical substances distribute The not all people of smell out can receive, so needing a kind of completely new air freshener can be on the market now Human body is played a certain protective role.
Volatile oil is in the flower from plant, leaf, stem, root or fruit, by steam distillation, extrusion, cold-maceration or Solvent extraction method refines the volatile flavor of extraction.It is used in daily life, purification air, disinfection, sterilization can be played The effect of, while some communicable diseases can be prevented.Different types of volatile oil effect is different, releives for some diseases With the function of mitigating symptom.Volatile oil is all helpful to many diseases, the treatment with composite medicine, can allow disease recovery Faster.Volatile oil for endocrine, metabolism, urinary system, venereal disease, immune system, gynecological disease, muscle, skeletal diseases, Skin disease, the symptom of body and disease, nervous system and mental disease, eye, ear, nose, oral cavity, odontopathy, respiratory system Disease in terms of the disease of aspect, blood circulation system, the disease in terms of digestive system have all well and good curative effect.
In recent years using natural plant extracts make air freshener or air purifying preparation as main component in quantity and It is all greatly improved in quality relative to traditional synthetic, but there is also antibacterial, the antibacterials of such as air freshener Effect is significant, the antibacterial time not persistently, smell is not pleasant enough, essential oil proportion is improper and has a stimulating effect on the human body etc. and to ask Topic.
Therefore how while keeping fragrance antibacterial range and effect are improved, and by manufactured air freshener to people The harm of body, which minimizes, even thoroughly eliminates a still project for being worth continuing deeper into research.
Summary of the invention
It is an object of the invention to overcome the defect of the prior art, a kind of air freshener is provided, energy dispelling abnormal flavor relaxes Slow mood refreshes the mind, sterilizing, antibacterial anti-inflammatory, safe and non-toxic, high-efficiency environment friendly.
The present invention is implemented as follows:
It is an object of the present invention to provide a kind of air fresheners, according to parts by weight its material composition include: 81~ The total hydrosol of 90 portions of plants and 19~21 parts of plant total volatile oils；Wherein,
