Abstract
The invention discloses an external preparation for avoiding stings of mosquitoes. The preparation contains acid, and the pH value of the preparation is between 4 and 6. The external preparation has variety of preparation formulations. The experimental results prove that the effects for avoiding the mosquitoes can last for more than 15 hours. The external preparation does not contain any pesticide, and is safe and has no toxicity for a human body for long-time use.
Description
Technical field:
The present invention relates to a kind of external preparation of preventing bite of mosquito, be specifically related to the preparation for external application to skin of pH value in 4~6 scopes.
Background technology:
Being used to spread upon the mosquito-repellent that prevents mosquito bite on the human body at present all contains insecticide both at home and abroad, is " diethyltoluamide " as the main effective ingredient of human body anophelifuge commonly used.
" diethyltoluamide " chemical name: N, the N-n,N-diethyl meta-toluamide, the external vehicle economy ET of diethyltoluamide is a kind of widely used insecticide.It is sprayed on skin or the clothes, avoids the worm mosquito bite.The general use amount of diethyltoluamide is 5-30% not wait effective 4-7 hours mosquito-proof time.
Although there are some researches show, the diethyltoluamide repelling effect is certain, and it does not feel well mosquito, has confirmed that the mosquito of the neuronic antennal sensilla of A type olfactory receptor has significant reaction to diethyltoluamide.But insecticide belongs to the pesticide management area, and is dangerous to human body.
Summary of the invention:
The purpose of this invention is to provide and a kind ofly do not contain insecticide, and prevent that mosquito bite is effective, the preparation for external application to skin safely and effectively of long action time.
Preparation for external application to skin of the present invention is the various external preparation that contain acid, and the pH value of preparation is in 4~6 scopes.
Described acid, comprise all mineral acids of preparation acceptable or organic acid, as in phosphoric acid, hydrochloric acid, lactic acid, malic acid, gluconic acid, adipic acid, oxalic acid, acetic acid, salicylic acid, citric acid, succinic acid, fumaric acid, ascorbic acid or the ascorbic acid one or more.Preferred organic acid is as acetic acid.
Contain multiple organic substances such as lactic acid, amino acids, amine in the perspiration that human body skin is discharged.Wherein, the aminoacids complex that the reaction of lactic acid and amino acids is generated can with the aminated compounds effect, generate trimethylamine (trimethylamine; TMA).Find that according to scientific research in recent years the main cause that human body is subjected to mosquito bite is because the synthetic trimethylamine of human body self has a kind of special abnormal smells from the patient, can attract mosquito consumingly.Therefore,, or reduce or eliminate trimethylamine, can play the effect of avoiding attracting mosquito, thereby prevent mosquito biting the people if can prevent the formation of human body surface trimethylamine.
The acid that is contained in the preparation of the present invention has two effects: 1, can react with amine substance, thereby stop amine substance and compounded amino acid reaction to generate trimethylamine; 2, for the trimethylamine that has generated on the human body skin, these acidic materials can react with it, play the effect that reduces or eliminates trimethylamine.
Preparation of the present invention can have multiple dosage form, as emulsifiable paste, emulsion, solution, ointment, spray etc., according to Various Seasonal, selects for use under the different situations.As can be made into forms such as cream, floral water, gel.
Except that active component acid and pharmaceutical base, also can contain conventional various adjuvant, the additive that uses of external agent in the preparation, as wetting agent, spice, coloring agent, antiseptic, emulsifying agent, surfactant, viscosifier, aerosol etc.
Also can add other effective ingredient as required to skin beneficiating, as vitamins, sun-proof class medicine etc.
The above addible other composition, those skilled in the art can select for use as required.As long as to the human body no side effects, and preparation can accept, and all can use.
The preparation method of preparation of the present invention is by the conventional preparation method preparation of general medicine external preparation or skin cosmetic.As acid being joined in the previously prepared pharmaceutical base, also acid can be carried out simultaneously the preparation of preparation as raw material and various other preparation raw material.No matter which kind of method should be controlled the finished product pH value in 4~6 scopes.
The using method of the mosquito-proof preparation of the present invention is preparation to be smeared or is sprayed on the human body skin or on the clothes, can play tangible mosquito repellent effect.
Consumption of this preparation and number of times can be according to using needs, and as mosquito density, go out the time, body surface exposed area etc. are grasped flexibly.Can one day with once or for several times.
As safe as a house because of this preparation, do not contain any insecticide and skin irritation material, life-time service is to the human body safety non-toxic.Repeatedly use repeatedly or continuously and also can not cause any harm human body.
Another aspect of the present invention is found this purposes of external preparation that can prepare preventing bite of mosquito with sour first.
What provide among the embodiment is the preparation of the ointment and the solution of several different formulations, and has provided and wherein fill a prescription 1 and the human body of diethyltoluamide preparation checking contrast experiment.The result shows: compares with the diethyltoluamide preparation, and acidic formulation anophelifuge better effects if of the present invention, mosquito-proof effective time is long.
