Description
Technical field
The invention belongs to cosmetic technical field, and in particular to a kind of nanometer platinum colloid for cosmetics.
Background technology
The skin of human health has natural defencive function, can resist the environment such as dust storm, cold, humidity, drying to skin
In the infringement of skin, keratoderma, the moisture containing 10%-20%, it, which is originated, is mainly the sweat of sweat gland secretion, to keep table
The plasticity of skin cuticula, soft and smooth, the moistening and elasticity of maintenance skin.But there are some researches show the skin of, the mankind is from 25-30
Year after will aging with advancing age and gradually, just occur about after 35-40 Sui comparison it is detailed aging change
Change, now, fibroblastic quantity is gradually decreased in human body skin, its secrete collagen and elastic fibers albumen also because
Gradually decrease, be broken to be oxidized, the supporting role to epidermis is just disappeared, skin corium start it is thinning, skin elasticity variation because
This cause it is inhomogenous collapse, generate wrinkle, wrinkle with skin metabolism hypofunction, blood supply reduces, sebum
Secretion reduction is closely related, causes skin dry, thinning；In addition, the skin of aging also has the elastic fibers and collagen of skin corium
Fiber is reduced, thicker, aging, and skin elasticity lowers；Subcutaneous fat is reduced, and skin is reduced support.Show old fell
The feature of skin structural change：It is dry, coarse, corrugate, the increase of loose and benign or malignant neoplasm incidence.
The skin of beautiful health, gradually fails in growing up jointly with the age.The face cleaning of mistake, skin care method, city
Air pollution, frequently color make-up can all hurt skin, accelerate the deterioration of skin state.Also, the skin regeneration once declined
Difficulty than larger.Therefore selection as early as possible, using the cosmetics and skin care method for being adapted to oneself skin, is to prevent skin aging, guarantor
Hold the key of beautiful health.Up to the present, as oxidation resistant main flow composition Co-Q10, substantially disposable play is made
With, that is, enter in vivo once having carried out antioxidation, just lose effect.But have 7 kinds of active oxygens in human body, it is auxiliary
The compositions such as enzyme Q10 can only remove a kind of active oxygen.Therefore, in cosmetics, Co-Q10 is replaced using new active component, is had
It is significant.
The content of the invention
For these reasons, applicant has found a kind of nanometer platinum colloid for cosmetics, this is received by studying for many years

Test method：Antioxidation activity is represented with scavenging ability of DPPH free radical size.Take 1 group of experiment, 2 groups of nanometers of experiment
The sample and Co-Q10 of platinum colloid, add 20mL1.52 × 10-4Mmol/L DPPH ethanol solutions are fully mixed,
Room temperature lucifuge is stood after 30min, using solvent as blank control, and absorbance A 1 is surveyed at 517nm；Replace sample molten with same volume solvent
Liquid does negative control, mensuration absorbance A2；Blank group, mensuration absorbance A3 are done instead of DPPH solution with same volume absolute ethyl alcohol.
Using Co-Q10 as control, every group is done 3 repetitions, seeks its average value.Clearance rate is calculated as follows：
Clearance rate (%)=[1- (A1-A3)/A2] × 100% of the sample to DPPH.
Conclusion (of pressure testing) is shown in Table 3.
Influence of the table 3 to DPPH free radical scavenging activities
Conclusion (of pressure testing)：Oxidation Resistance Test shows that nanometer platinum colloid antioxidant effect of the invention is that Co-Q10 group is thought
When, but actually used active component consumption (nanometer platinum) is the half of Co-Q10.
