Description
Technical field
The present invention relates to starch technical field, in particular to a kind of converted starch composition and its application.
Background technique
Starch is the carbohydrate that plant is formed through photosynthesis, it is from a wealth of sources, cheap, degradation after still with
The form of carbon dioxide and water returns to the Nature, it is considered to be the material for the natural reproducible not polluted, in non-edible field
Extensive research and development is obtained.It is melted since starch has not dissolving in poor cold water, shear resistant, poor water resistance and lack
The disadvantages of mobility, it is modified next to need to carry out it Chemical Physics so that it is difficult to use separately as a kind of high molecular material
Enhance certain functions or forms new physicochemical characteristic.Currently, as new converted starch raw material can widen answering for converted starch
With field, the development of converted starch is pushed.In addition, starch also has more research in the application of cosmetic field, but will form sediment
Powder carry out denaturation be reused in it is less in cosmetics, especially in the cosmetics of anti-acne class.Pass through in existing product for resolving poxes
The breeding for inhibiting bacterium eliminates its stimulation and its destruction to tissue, or passes through laser irradiation, quick anti-acne, still
It is too big to the stimulation of skin, it cannot fundamentally solve the problems, such as anti-acne or even the big chemical reagent of irritation to impaired skin
There is bigger damage.If the raw material that converted starch is produced as anti-acne lotion, itself has thickening, functional work
With so that cosmetic product have more stable architecture, indirectly in reduction system preservative use so that product
Safer, therefore, studying application of the converted starch in cosmetics has great meaning.
A kind of converted starch composition, the practical problem urgently handled in practical application are specific there are also not proposing very much
Solution.

Born of the same parents resource center), anti-acne lotion, the mouse prostate element E2 (PGE2) of the anti-acne lotion of Examples 1 to 4 and comparative example 1~4
ELISA detection kit, murine tumor necrosis factor-α (TNF-α) ELISA detection kit, lipopolysaccharides (LPS).
Method: (1) influence grown with mtt assay detection anti-acne lotion to RAW264.7 cell adjusts RAW264.7 cell
Density is inoculated in 96 porocyte culture plates, every 1000 μ L of hole to 5x104/mL, is placed in 37 DEG C, in 5%CO2 cell incubator
Culture is for 24 hours.The culture medium in cell plates is sucked out after culture, it is 500 200 μ of μ g/mL biology that concentration is separately added into processing group
Isometric serum free medium is added in the L dilution of lotion containing anti-acne, blank control group, continues to cultivate for 24 hours, every group of 3 multiple holes.
After for 24 hours, the MTT solution of every group of 20 μ L of addition continues after cultivating 4h, takes out 96 orifice plates, liquid in hole is sucked out, is added 150 μ L's
Absorbance (A) value is measured at 490nm after DMSO, concussion 5min, calculates the survival rate of cell.Survival rate=medicine group average A-value/
Blank control group average A-value.
(2) influence of PGE2, respectively control group (serum-free training are discharged to lipopolysaccharides (LPS) stimulation RAW264.7 cell
Support base), Examples 1 to 4 distinguishes administration group (LPS of the anti-acne lotion of 100 μ g/mL and 1 μ g/mL), 1~4 group of (100 μ of comparative example
The LPS of the comparative example of g/mL and 1 μ g/mL), cell culture and method and (1) together, collect cell conditioned medium after LPS stimulates 18h
Liquid requires to carry out PGE2 detection according to ELISA kit specification, calculates inhibiting rate, be denoted as inhibiting rate 1.
(3) influence of TNF-a, respectively control group (serum free medium) are discharged to LPS stimulation RAW264.7 cell, it is real
It applies example 1~4 and distinguishes administration group (LPS of the anti-acne lotion of 100 μ g/mL and 1 μ g/mL), (100 μ g/mL's dispels Examples 1 to 4 group
The LPS of acne lotion and 1 μ g/mL), LPS collects cell conditioned medium after stimulating 18h, carries out by the operation requirement of ELISA kit specification
TNF-a detection, calculates inhibiting rate, is denoted as inhibiting rate 2, the results are shown in Table 1.
Table 1
By the data analysis of survival rate in table 1 it is found that the anti-acne lotion acellular poison side effect of preparation, ingredient is mildly, no
Stimulation；It analyzes from the data of inhibiting rate 1 and inhibiting rate 2 it is found that illustrating to apply converted starch composition and is preparing anti-acne
It in liquid, can effectively inhibit the release of the cellular inflammation factor, assign the good anti-inflammatory efficacy of cosmetics.

Test method: referring to National Standard of the People's Republic of China GB15797-2002, " Disposable Sanitary Accessory is defended
Appendix C 4 " stripping property resists (suppression) bacterium product bacteriostasis property test method " in raw standard ".
Operating procedure:
(1) test organisms for 24 hours washed down with 0.03mol/LPBS by culture, is made 106Cfu/mL bacteria suspension.
(2) above-mentioned bacteria suspension 0.1mL even spread mixing is added in each 1g of the anti-acne lotion of Example 3 and comparative example 3, opens
After beginning timing 20min, 9mL0.03mol/LPBS is added and mixes well, after making appropriate dilution, takes wherein 2-3 dilution, respectively
It takes 1mL to be placed in two parallel plates, adds corresponding culture medium difference Hybrid NC machine tool.Make colony count.The above test repeats 3
It is secondary, its average is taken, while setting blank control.
It calculates: X=(A-B)/A × 100%
In formula: X --- bacteriostasis rate, %
A --- control sample averagely recycles bacterium colony；
B --- test specimen averagely recycles bacterium colony.
Bacteriostasis efficacy evaluation: efficacy assessments divide three-level: it is effective, effective and invalid, such as the following table 2.
Table 2
According to above-mentioned test method, the bacteriostatic test of 20min is carried out, the results are shown in Table 3.
Table 3
By the data analysis of table 3 it is found that converted starch composition of the invention is applied in preparation anti-acne lotion with aobvious
The fungistatic effect of work prevents microbial reproduction and secretion harmful substance, causes the generation and deterioration of cellular inflammation.
In other test, the anti-acne lotion that will be prepared in embodiment 3 and comparative example 3 is heated to 45 DEG C, shakes 2h
Afterwards, it places, observes the stability of anti-acne emulsion system, the anti-acne lotion obtained in comparative example 3 is placing 12d, occurs light
Micro- lamination, and the product integral system that embodiment 3 is prepared is stablized, and illustrates converted starch composition in cosmetics
It plays a role in system.
Above the embodiments of the present invention are described in detail, but the present invention is not limited to described embodiments.It is right
For those skilled in the art, in the case where not departing from the principle of the invention and spirit, these embodiments are carried out more
Kind change, modification, replacement and modification, still fall in protection scope of the present invention.
