The Herba Menthae astringent
Technical field:
The present invention relates to a kind of astringent, particularly a kind of Herba Menthae astringent.
Background technology:
Watery skin care item claim again astringent, are the liquid skin protection cosmeticss of a kind of low viscosity, good fluidity.In numerous cosmetics, astringent is with its unique effect, is convenient to use and takes the course of its own.This series products has cleaning, moistens, the effect of soft, convergence.
Comprise a large amount of nutrient substance in the astringent, can provide abundant nutrition for skin, moisture and oil content that can conditioning skin, that Glycerin makes it is more soft, be rich in gloss.Nutritional labeling is soluble in water, and skin more easily absorbs.Surfactant in the astringent can be removed the dirt that is present on the skin, and cleaning skin guarantees the normal physiological activity of skin.Wetting agent in the astringent is except giving skin with moistening, and the moisture of all right regulation of skin makes it to keep soft, moist.In addition, astringent is restrained the effect of pore in addition, and this can make skin look bright and clean exquisiteness; Some curative effect astringent that are added with medicine also have the effects such as speckle dispelling, sun-proof, whitening, sterilization.
Summary of the invention:
For the prior art above shortcomings, technical problem to be solved by this invention provides a kind of Herba Menthae astringent.
Technical problem of the present invention is achieved by following technical proposals:
A kind of Herba Menthae astringent comprises following component: Satureia hortensis oil, hyaluronic acid, decoyl both sexes guanidine-acetic acid sodium, G ﹠ W.
A kind of Herba Menthae astringent comprises the component of following weight parts: 0.2-0.6 part Satureia hortensis oil, 0.5-1.5 part hyaluronic acid, 0.5-1.5 part decoyl both sexes guanidine-acetic acid sodium, 6-10 part glycerol, 100 parts of water.
Preferably,
A kind of Herba Menthae astringent is comprised of the following weight parts raw material: 0.2-0.6 part Satureia hortensis oil, 0.5-1.5 part hyaluronic acid, 0.5-1.5 part decoyl both sexes guanidine-acetic acid sodium, 6-10 part glycerol, 0.05-0.15 part whitening agent, 100 parts of water.
Described whitening agent is made of by weight following component: 10-30 part phloretin, 10-30 part arbutin, 10-30 part Licochalcone A.
Satureia hortensis oil claims again: European Herba Menthae, Savory, CAS number: 8016-68-0.
Hyaluronic acid, Hyaluronic acid, CAS number: 9004-61-9.
Decoyl both sexes guanidine-acetic acid sodium, SODIUM CAPRYLOAMPHOACETATE, CAS number: 68647-46-1.
Phloretin, English name: Phloretin, CAS accession number: 60-82-2.
Arbutin, English name: Arbutin, CAS accession number: 497-76-7.
Licochalcone A, English name: Licochalcone A, CAS accession number: 58749-22-7.
Obviously can also add other raw materials in the present invention, such as chelating agen, antibacterial, pigment etc., other raw materials add basic its function separately that realizes, usually can not affect key property of the present invention.Those skilled in the art need not to pay creative work and can implement.
Herba Menthae astringent of the present invention can adopt industry universal method to be prepared from, and for example decoyl both sexes guanidine-acetic acid sodium is dissolved in the water, and adds hyaluronic acid and glycerol, stir, add again Satureia hortensis oil and whitening agent, mix, can make this Herba Menthae astringent.Obviously, preparation method adopts known technology, is not innovation of the present invention.
Herba Menthae astringent of the present invention can effectively prevent skin ageing, moisturizing, unobstructed pore, level and smooth skin.After adding whitening agent, can eliminate the melanin on the skin, skin whitening.
The specific embodiment:
Following embodiment further specifies of the present invention, rather than limits the scope of the invention.In the present invention, if no special instructions, each raw material is all take working substance content as 100%.
Embodiment 1
Take by weighing: 0.4 kilogram of Satureia hortensis oil, 1 kilogram of hyaluronic acid, 1 kilogram of decoyl both sexes guanidine-acetic acid sodium, 8 kilograms of glycerol, 100 kg of water.Decoyl both sexes guanidine-acetic acid sodium is dissolved in the water, adds hyaluronic acid and glycerol, stir, add again Satureia hortensis oil, mix, can make this Herba Menthae astringent.
Embodiment 2-5
Embodiment 2-5 data by table 1 correspondence take by weighing each raw material respectively.Each raw material is at room temperature mixed, decoyl both sexes guanidine-acetic acid sodium is dissolved in the water, add hyaluronic acid and glycerol, stir, add again Satureia hortensis oil and whitening agent, mix, can make this Herba Menthae astringent.

Test case:
25 female volunteers are selected in experiment altogether, measure melanin content in the human body skin, and the white-skinned face function of astringent product is estimated.
5 healthy womens are selected in every group of test, age is in 20-40 year, sign Informed Consent Form with study subject, adopt the MEXAMETERMX18 skin pigment instrument of German Courage+Khazaka company using astringent front 1 day and using continuously astringent to measure afterwards the melanin content of its skin of face in 14 days.Measure environment: test environment temperature (22 ± 1) ℃, humidity (50 ± 5) % averages.Study subject uses the astringent product one time every day, and using method is: behind the cleaning facial skin, dry, with hands astringent is patted on facial skin.Study subject does not use other whitening products at test period.
This instrument of MEXAMETERMX18 skin pigment instrument is based on the principle (RGB) of spectral absorption, and the volume reflection of the illumination by measuring specific wavelength after on human body skin determined melanic content in the skin.The emitter of instrument probe sends rayed that wavelength is respectively 568nm, 660nm and three kinds of wavelength of 880nm at skin surface, and accepter records the light of skin reflex.Because radiative amount is certain, therefore just can measure the amount of the light that is absorbed by the skin, measure the content of dermal melanin.The measuring range of instrument is 0-999, measures numerical value higher, illustrates that melanin content is higher in the skin.
Melanin reduction rate=(use the front 1 day melanin content of astringent-use continuously astringent after 14 days melanin content) ÷ uses the front 1 day melanin content of astringent * 100%.The melanin reduction rate is higher, illustrates that whitening effect is more obvious.

The test data of experiment of associative list 2 can be found out: with the composite use of phloretin, arbutin and Licochalcone A, for white-skinned face function, played obvious synergistic function significantly.
