A kind of amino acid pattern faintly acid facial cleaning cream and preparation method thereof
Technical field
The present invention relates to the daily cosmetics technical field, relate in particular to a kind of have clean, the facial cleaning cream of skin-protecting function and preparation method thereof.
Background technology
As the daily cleaning cosmetic product, the performance quality of facial cleaning cream has very big influence to skin.The acid-base value of reason that skin is good and bad and skin and cosmetics (being pH value) has close contact.Human body skin surface is being owing to retaining acidic materials such as carbamide, uric acid, salinity, lactic acid, aminoacid, free fatty, so skin surface is faintly acid usually, and the pH value of healthy Asians's skin should be between 4.5~6.5.Skin only in its normal pH value scope, just is in faintly acid, just can make skin be in the optimum state that absorbs nutrition, and have the health status of the bests such as elasticity, gloss, moisture and resist extraneous erosive ability.
The weakly acidic condition of skin surface all has certain buffer capacity to acid, alkali, is called the neutralising capacity of skin.Wherein, skin is called deacidification to the cushioning effect of the acidic materials of pH value in 4.5~6.5 scopes; Skin is called the alkali neutralization to the cushioning effect of alkaline matter.When skin surface receives the stimulation of alkaline matter and when changing pH value, tart panniculus is also had the ability at short notice, original index is returned in the acid-base value adjustment of skin surface, this ability is called " the alkali neutralising capacity " of skin.Getting well with bad of skin, key are whether skin is healthy, and whether health is embodied on the alkali neutralising capacity of skin.Different people changes between 4.5~6.5 usually at the pH value of different times skin, also can exceed this scope sometimes.If outside 4.5~6.5, the alkali neutralising capacity of skin will weaken the skin pH value for a long time, skin matter will change, and finally causes the old and feeble and infringement of skin.Therefore, have only the corresponding skin care item of apolegamy, the skin pH value is remained between pH4.5~6.5, skin just can present optimum state, really reaches more beautiful, more healthy effect.
At present, the facial cleaning cream of prior art mostly is that pH value is usually more than 9.5 based on soap base class (fatty acid adds the alkali neutralization and forms).Clean product of this class has very strong cleaning effect, uses aftersensation very clean, used a period of time even after skin also can seem transparent.Yet the skin of this moment is not really to improve, but exfoliation excessively and hurt the illusion that skin produces.Cleaning effect is fine on this series products surface, but is in fact damaging skin silently, because its pH value is higher, so life-time service is understood injured skin unavoidably.For this reason, improve the performance of clean product comprehensively, when having clean surface functions such as the facial dust of removal, oils and fats, also have the effect of safeguarding skin health, being not only the skin protection method and the development trend of clean product science, also is the growing demands of consumers in general simultaneously.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art; provide a kind of contained for the All Pure Nature amino acid type surfactant, do not contain the amino acid pattern faintly acid facial cleaning cream of soap matter; when removing various dirt with gentleness; safeguard the weak acid environment of skin; and at skin surface formation protecting film, thereby reach the purpose of safeguarding skin health.Another object of the present invention is to provide the preparation method of above-mentioned amino acid pattern faintly acid facial cleaning cream.
Purpose of the present invention is achieved by the following technical programs:
A kind of amino acid pattern faintly acid facial cleaning cream provided by the invention, its raw material consists of by weight percentage: amino acid surfactant 15~40%, wetting agent 5~30%, emulsifying agent 2~15%, thickening agent 0~3%, surplus are deionized water.Preferably consist of: amino acid surfactant 18~32%, wetting agent 10~25%, emulsifying agent 3~12%, thickening agent 0.5~3%, surplus are deionized water.
Wherein, amino acid surfactant of the present invention is the one or more combination of fatty acyl group glutamate, fat acidyl glycine salt class, fatty acyl group alanine salt.One or more combination with sodium lauroyl glutamate salt, cocoyl sodium glutamate, cocoyl glycine potassium salt, cocoyl alanine sodium salt is advisable.
Wetting agent of the present invention is the one or more combination of polyhydric alcohol, amino acid humectant, nature moisturizing factor NMF.Preferably, be the one or more combination of propylene glycol, glycerol, trimethyl glycine lactone, L-pyrrolidone sodium carboxylate.
Emulsifying agent of the present invention is the one or more combination of refining Apis cerana Fabricius, glyceryl stearate, stearyl alcohol polyoxyethylene (21) ether, polyoxyethylene sorbitan fatty acid ester, Span.Preferably, be a kind of of refining Apis cerana Fabricius, glyceryl stearate or its combination, wherein the fusing point of refining Apis cerana Fabricius is 35~42 ℃.
Thickening agent of the present invention is the one or more combination of the two stearates of polyethylene glycol 6000, methyl glucoside polyoxyethylene (120) ether dioleate, acrylate/polyoxyethylene-20 octadecanol ether methyl-prop diluted acid ester copolymer, hydroxyethyl-cellulose, acrylate copolymer.
In addition, in formula system of the present invention, can also add an amount of essence, antiseptic as required.
Another object of the present invention is achieved by the following technical programs:
The preparation method of above-mentioned amino acid pattern faintly acid facial cleaning cream provided by the invention is: each component is added in the deionized water, and stirring makes it to disperse; Be heated to 80~85 ℃ then, stirring and dissolving 30~60min leaves standstill to remove blibbing slightly to transparent clarification shape; Be cooled to 43~50 ℃, treat that dissolved transparent fluid viscosity increases when beginning to be emulsion form and slowly having pearly-lustre to separate out, continue to stir 30~45min, promptly get the paste finished product after leaving standstill 12~24h.
The present invention has following beneficial effect:
(1) facial cleaning cream of the present invention adopts the All Pure Nature amino acid type surfactant to make, and 100% does not contain soap matter, and its clean skin composition can gentlely effectively be removed various dirts, and forms protecting film at skin surface, thereby realizes safeguarding the purpose of skin health.
(2) goods itself are faintly acid, pH value is stabilized between 5.5~6.5, in full accord with the mean ph value of skin, the skin affinity is outstanding, chafe does not have tight sense, can recover skin protection function behind the clean skin rapidly, make skin profit, acid-base balance, but be fit to any skin matter and life-time service.
(3) need not in the product compounding system to add adjuvants such as pearlescent flake or Pearl Concentrate,, can obtain the pearly-lustre toothpaste-like effect of the beautiful exquisiteness of outward appearance by the distinctive apparent pearly-lustre characteristic of amino acid surfactant.
(4) preparation method of the present invention is simple, and physical process just, does not relate to chemical reaction, so processing and preparing produces and be reversible process, and the product of shaping still can reheat allotment.
