Embodiment 1
Be mixed with cosmetics cream frost according to prescription and preparation technology in the table.Arecaline is mixed with the 50mg/100mL propylene glycol solution, the propylene glycol solution that then will contain arecaline slowly joins in the cream frost, make the ultimate density of arecaline reach 50 μ g/g, under the condition that keeps the evaporation of temperature constant and minimum moisture, slowly stir evenly packing.
The purity of the arecaline 〉=100 year red moral detection technique of poem in 98.0%(Shanghai company limited).
Standard substance of the present invention is for detection of the uniformity testing of cosmetic kind arecaline:
Homogeneity is the most basic attribute of standard substance, project (GB/T15000.9-94) is randomly drawed the n bottle to the standard substance of developing according to " standard model work guide rule (5): chemical composition standard model technology general rule ", with wherein one bottle as basic contrast points, all the other n-1 bottles adopt corresponding mathematical statistics method that the homogeneity of each standard substance is studied as check point.
1.1 uniformity testing method:
With F method of inspection and t method of inspection.
Specific practice is: in 16 bottles of samples that extract, optional one bottle of basic contrast points of conduct is done the measurement of one group of 15 target component (arecaline) content altogether; All the other 15 bottles as the checkpoint, makes target one time for every bottle.
1.11 the significant difference with the F method of inspection check sample variance of getting has following judgment formula:
In the formula:
S
1 2The variance of-checkpoint;
S
2 2The variance of-contrast points;
F α (ν
1, ν
2)-given level of significance α and degree of freedom (ν
1, ν
2) the critical value of statistical test, F α (14,14)=2.48 tables look-up;
ν-degree of freedom, v=n-1.
When satisfying formula (1), then there is not significant difference in two groups variance.
1.12 the significant difference of t method of inspection check this mean value of taking a sample has following judgment formula:
In the formula:
x
1The measurement mean value of-checkpoint;
x
2The measurement mean value of-contrast points;
When satisfying formula (2), there is not significant difference in two groups mean value.
1.2 sampling number
The total sample number N of each kind is 200 bottles, by 3
Calculate sampling number, randomly draw 18 bottles, wherein get 16 bottles and make uniformity testing.
1.3 sample mode
Press table of random numbers sample drawn, remove repetition and useless, extract 16 bottles of samples.
1.4 check instrument
Liquid chromatograph, model: Agilent 1260.
If there are not significant difference in F method of inspection and t method of inspection result, illustrate that then this standard substance is uniform.
By the data of table 1 and table 2 as can be known, in level of significance α=0.05, the degree of freedom of inspection group and contrast groups is that (F 0.05 (14 in 14 the situation, 14)=2.48, t (0.05,28)=2.05), the content measuring result all meets (1) formula and (2) formula, therefore can judge two groups of results' mensuration variance indifference, measure the mean value indifference.
