Test example 1 safety evaluation
The tightening skin anti-wrinkle essence prepared in examples 1 to 7 and comparative examples 1 to 13 of the present invention were subjected to safety evaluation. The results were as follows:
the standard of sanitary chemistry and microbiology has lead content less than 10mg/kg, mercury less than 0.05mg/kg, arsenic less than 1mg/kg, total bacteria less than 10cfu/mL, and no detection of fecal coliform, staphylococcus aureus and pseudomonas aeruginosa. The indexes meet the specification of national 'hygienic Standard for cosmetics' GB 7916-87.
The acute oral toxicity test of mice shows that the acute oral toxicity LD 50 values of female and male mice are both larger than 5000mg/kg body weight, and the acute oral toxicity test belongs to the actual non-toxic grade according to GB7919-87 chemical acute toxicity grading standards.
Skin multiple stimulation test, skin stimulation integral is greater than 0.4, less than 0.5, pathological histology integral <4. The skin irritation intensity evaluation standard according to the chemical substances GB7916-87 meets the national standard of cosmetic hygiene, and belongs to the light irritation substances.
Test example 2 clearance to DPPH
The compact dermatological anti-wrinkle essence prepared in examples 1 to 7 and comparative examples 1 to 13 was diluted with deionized water to 1mg/mL as a sample solution. Vitamin C was used as a control group.
Respectively taking 2.00 multiplied by 10 -4 mol/L DPPH absolute ethyl alcohol solution and 3mL of sample solution, adding into a test tube, shaking uniformly, placing for 30min in a dark place, measuring absorbance A i of the mixed solution at 517nm, simultaneously measuring absorbance A 0 of 3mL of pure water mixed with 3mL of DPPH absolute ethyl alcohol solution and absorbance A j of 3mL of sample solution mixed with 3mL of absolute ethyl alcohol, and calculating the clearance (%) of DPPH according to a formula. The results are shown in Table 1.
DPPH clearance (%) = [1- (A i-Aj)/A0 ]. Times.100%)
TABLE 1
As shown in the table above, the compact anti-skin wrinkle essence prepared in the examples 1-3 of the invention has better antioxidant activity.
Test example 3
Face was selected as the test site, and subjects meeting the conditions were selected to be divided into 20 groups of 10 persons each of examples 1 to 7 and comparative examples 1 to 13, respectively. The subjects used the compact dermatological anti-wrinkle essence prepared in examples 1 to 7 and comparative examples 1 to 13 as test products according to the use requirements, collected skin data at the corresponding test sites of the subjects, and analyzed the change of the skin data before and after the use of the samples in the test areas.
Improvement rate (%) = | (last data-initial data) |/initial data×100%
The improvement rate is absolute value, the improvement rate is guaranteed to be always positive, and when the essence is used in actual test, the moisture content of the skin cuticle is improved, the skin elasticity R2 value is improved, and the skin compactness F4 value is reduced.
The specific test process is as follows:
test conditions subjects on the day of the test were allowed to sit still for 30min in a laboratory at a temperature of (25.+ -. 1) °C and humidity of 45%.+ -. 5% RH with the designated facial samples for facial cleansing.
Test method Corneometer test skin stratum corneum moisture content, cutometer test elasticity R2 value, and compactibility F4 value. The results are shown in Table 2.
(1) Test subject skin initiation data prior to the start of the experiment.
(2) After the initial data acquisition is completed, samples are dispensed to the subjects, full face smears are carried out once a day for 1 week, and the last data of the skin of the subjects are tested under the same test conditions after 1 week.
