A kind of cooling patch and preparation method thereof of sleeping that relaxes
Technical field
The invention belongs to medical art, relate to a kind of dormancy temperature-reducing paste that relaxes.
Technical background
Temperature-reducing paste is also referred to as defervescence plaster used, is affixed on human skin, utilizes the TDDS technology of international popular to make moisture and drug transdermal enter skin, and the physical change of then being absorbed heat by water vapor is reached falls hypothermic effect.It belongs to Physical temperature-lowering articles for use, is widely used in fever of children fever and summer-heat removing.Temperature-reducing paste composition in the market mainly based on polymer substance and Mentholum, Borneolum Syntheticum, only has simple cooling effect, without dormancy effect of relaxing.No matter and fever is generated heat or summer-heat is unbearable, all easily make people irritated, headache, whole body is uncomfortable, also difficulty of falling asleep.Now be more suitable for using the temperature-reducing paste with easypro dormancy effect.
Pinaster stump wood temples part rotten rear remaining conjunction fat portion collection, the dry distilling gained liquid of asbolin system over-logged forest area, have the effect of tranquillizing and allaying excitement.The inhalant that asbolin is made belongs to nonprescription drugs, and the adjuvant drug as insomnia uses.
Herba Lysimachiae foenum-graeci quintessence oil is refined by lavandula angustifolia and forms, and is usually used in controlling oily skin protection and fatigue alleviating, has good effect to relieving mental strain and helping sleep.In addition the quiet and beautiful fragrance of lavandula angustifolia is also extensively liked, therefore Herba Lysimachiae foenum-graeci quintessence oil is broadly used as essence and flavoring agent.
Mentholum system is by the white crystal extracted in the leaf of Herba Menthae and stem, and the refrigerant sense of its clearing away heat and removing summer effect and uniqueness thereof makes it be widely used in each fields such as menthocamphorate processed, analgesic, toothpaste, confection, beverage.
Asbolin, Herba Lysimachiae foenum-graeci quintessence oil and Mentholum all derive from natural plant extracts, and safe without toxic side effect is combined together, and have unique pleasant delicate fragrance, add in gel and slowly discharge, lasting fragrance, relieving mental strain and helping sleep, be more conducive to the performance of cooling effect.
Summary of the invention
The object of the present invention is to provide a kind of have to relax sleep and patch and preparation method thereof of cooling effect.
The present invention is achieved by the following technical solutions:
A kind of cooling patch and preparation method thereof of sleeping that relaxes, it is characterized in that: be made up of backing layer, gel layer and mould release membrance, gel layer is made up of the component of following percentage by weight: polymer substance 5-15 part, cross-linking agent and cross-linking regulator 0.2-2 part, wetting agent 10-30 part, asbolin 0.01-0.05 part, Herba Lysimachiae foenum-graeci quintessence oil 0.01-0.05 part, Mentholum 0.01-0.05 part, ethanol 0.2-1 part, purified water 55-85 part.
Described polymer substance is the mixture of one or more in carbomer, carboxymethyl cellulose, hypromellose, sodium polyacrylate, gelatin, polyvinyl alcohol, polyvinylpyrrolidone.
Described cross-linking agent is the mixture of one or more in aluminum, aluminum chloride, aluminium sesquioxide, dihydroxyaluminum aminoacetate, and cross-linking regulator is the mixture of one or more in citric acid, tartaric acid, glacial acetic acid, citric acid, formic acid.The ratio 1: 0.5 ~ 5 of cross-linking agent and cross-linking regulator.
Described wetting agent is the mixture of one or more in glycerol, propylene glycol, Polyethylene Glycol, vitamin E.
Described backing layer is non-woven fabrics or stretch fabric.
Described mould release membrance is PE film or PET film.
A kind of preparation method of easypro cooling patch of sleeping is as follows:
(1) polymer substance is got and cross-linking regulator adds purified water, stirring and dissolving;
(2) cross-linking agent and wetting agent mixing and stirring is got;
(3) by above-mentioned two solution mix and blends uniformly gel;
(4) get asbolin, Herba Lysimachiae foenum-graeci quintessence oil, Mentholum dissolve with ethanol, add in gel, stir;
(5) the above-mentioned gel prepared is applied on backing through coating machine, covers mould release membrance simultaneously;
(6) required size and shape is cut into, packaging.
Advantage of the present invention is: the invention provides a kind of hydrogel patch with relax dormancy and cooling double effects, easy to use, can repeatedly paste, do not hinder skin, noresidue, abnormal smells from the patient delicate fragrance is pleasant, nontoxic, easypro dormancy and cooling effect lastingly, are particularly useful for fever heating and cooling of relieving summer heat.
Detailed description of the invention
