A kind of moisturizing astringent and preparation method thereof
Technical field
The present invention relates to a kind of moisturizing astringent and preparation method thereof, belongs to cosmetic field.
Background technology
With economy, the increasingly improvement of living standard, the basis maintenance of skin has turned into a part for daily life, moisturizing
It is one of most important function in skin protection cosmetics.Skin it is delicate, plentiful, whether beautiful it is critical only that it is aqueous in skin
Amount, the important channel of moisture of skin is to maintain using moisture-keeping cosmetics.Contain moisturizing in so-called moisture-keeping cosmetics, i.e. cosmetics the inside
Composition, the water content that keratoderma can be kept certain can increase moisture of skin, humidity, to recover the gloss and elasticity of skin.
Toner in the market mainly has based on transparent type and emulsifying.Transparent type toner, mainly uses sweet
The material with moisture absorption aquation such as oil, butanediol, high molecular weight water soluble polymer carries out moisturizing, and this kind of material had from week
The function that collarette border absorbs water, therefore under conditions of relative humidity is high, the moistening effect to skin is fine.But transparent type
Toner is very low in relative humidity, and cold is dried, windy weather, can be absorbed water from skin inner layer, and makes skin drier,
Cutaneous normal function, simultaneously because with the addition of high molecular polymer, has obvious sticky sense when smearing.
Due to the addition of grease in emulsifying toner, product appearance is translucent or milky, is protected by grease
It is wet, closed film can be formed in skin surface, so that transepidermal water loss (TEWL) is reduced, while can also prevent skin from being absorbed from the external world
Moisture.Its shortcoming is excessively greasy, is only suitable for extremely dry skin or is used in bone-dry winter.

As can be seen from Table 3:The moisturizing astringent of the embodiment of the present application 1,5,6 is the oil-dispersing property emollient containing parcel
And/or moisturizing astringent I, V, VI of the oil-soluble emollient of parcel, its using effect is substantially better than comparative example 1 and comparative example 2
Moisturizing astringent VIII-IX.In addition, carrying out using effect survey to the moisturizing astringent II-IV that embodiment 2-4 is prepared
Examination, the moisturizing astringent II-IV that embodiment 2-4 is prepared possesses equally good use result.
Moisture content of skin is tested
Choose 20~35 years old tested volunteer 19 of women, wherein more than 30 years old 3,20~30 years old 16.Choose upper arm
Two symmetrical regions of inner side, respectively as control group and the test zone of test group, in the environment (temperature 22 of constant temperature and humidity
DEG C, humidity 55%) tested, test the moisture of skin.Test group is obtained from embodiment 1 and embodiment 7 are prepared
Moisturizing astringent I and VII, the moisturizing astringent VIII that control group is prepared from comparative example 1, the two is under the same conditions
Do same test.Moisture test period is 3.5 hours, at interval of test in 30 minutes once.
Tested using capacitance method principle, moisture measurement probe vertical is pressed in tested skin surface, probe top
A segment distance is pushed back, there is a spring to make probe top keep the pressure of 0.16N to be pressed in skin surface 1 second inside probe, measured
Humidity measurements (Moisture Measurement Value, MMV).The humidity measurements are between 0~150.
The skin of Medial upper arm is cleaned, volunteer sits quietly 0.5 in the environment of constant temperature and humidity (22 DEG C of temperature, humidity 55%)
After hour, carry out two initial humidities of test zone using skinanalysis apparatus (German CK, Cutometer MPA580) and measure
The measurement of value.After 0.5 hour, then moisturizing prepared by the embodiment 1 and embodiment 7 for smearing equivalent in two test zones respectively
The moisturizing astringent VIII that adornment water I and VII is prepared with comparative example 1, and two humidity measurements in region are tested, interval time point
Wei 0.5 hour, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 3.5 hours.Every subject is measured in test group
With the skin moisture content in control group region, each test data is recorded.The humidity that the result of skin moisture content passes through setting
Measured value is represented.
Each test data is subtracted the change of the initial humidity measured value as period humidity measurements, then divided by initial
Humidity measurements are to draw skin moisture content growth rate, as shown in table 4, table 5 and table 6.
Skin moisture content Growth Rate Calculation formula is:
Skin moisture content growth rate %=(MMVt-MMV0)/MMV0× 100%
Wherein, MMV0:The initial humidity measured value of skin before smearing;
MMVt:The humidity measurements of t period skins after smearing.
