(3) performance test
1. zest test, adopt Red Blood Corpuscle test (RBC test, erythrocyte haemolysis value) characterize, test with fresh Sanguis Bovis seu Bubali erythrocyte (from animal science institute of Agricultural University Of South China), with SDS (sodium lauryl sulphate) for reference, the experimental technique of RBC operates with reference to such as Publication about Document: Li Yang, Dong Yinmao, Meng Hong, wish an ancient unit of weight .7 kind Chinese herbal medicine extract antiallergic effect and zest research [J]. Chinese experimental pharmacology of Chinese medical formulae magazine, 2013,19 (4): 191-194.Result is as shown in table 1.
Table 1 haemolysis pH-value determination pH result (%)
As can be seen from Table 1, embodiment and the surfactant system erythrocyte haemolysis value prepared by comparative example all much little compared with SDS, but the gentle surfactant system prepared by embodiment is owing to arranging in pairs or groups rationally, comparatively comparative example is lower to make erythrocyte hemolysis value.
2. stimulation index measures: adopt zein method, zein (zein) is almost completely water insoluble, but after its and surfactant interact, water solublity increase; Than weak zest surfactant, there is the trend more easily making zein dissolve compared with the surfactant of strong and stimulating.Therefore according to the situation of change of nitrogen content before and after Action of Surfactant in aqueous solution, the dissolubility after zein and Action of Surfactant can be determined, and the nitrogen content in the zein dissolved is directly proportional to the skin irritation that surfactant causes, the irritating size of surfactant can be judged thus.Zein method measures stimulation index and operates with reference to such as Publication about Document: Dong Yinmao, this knows sail, Peng Jinluan. by the zest [J] of zein test surfaces activating agent. and daily chemical industry, 2002,32 (5): 59-61.Zein value is greater than the surfactant of N 4g/L for " strong and stimulating ", and this type of surfactant makes zein solubilising power stronger; Zein value is " low stimulation " at the surfactant of N 2 ~ 4g/L; Be less than the surfactant of N 2g/L for " non-stimulated ".
Detecting sample arranges as follows: the surfactant system of 0.3% (w/w) SDS, 0.3% (w/w) SDS+0.75% (w/w) embodiment 1 preparation, the surfactant system of 0.3% (w/w) SDS+1.5% (w/w) embodiment 1 preparation.
As shown in Figure 1, as can be seen from Figure 1, the surfactant system of the gentleness prepared by embodiment 1 has the irritating effect of collaborative reduction surfactant to experimental result, and the embodiment 1 of 1.50% can make the SDS almost nonirritant of 0.30%.
2. formulation stability test:
Sensory testing: the character of perusal product, sees if there is exception;
Heat resistant test: electro-heating standing-temperature cultivator 24h sample being put into (40 ± 1) DEG C, observes phenomenons such as whether having thinning, variable color, layering and firmness change, with the heat resistance of judgement sample after recovering room temperature;
Low temperature resistant test: sample is put into (-5 ~-10) DEG C ± electric refrigerator 24h of 1 DEG C, observes phenomenons such as whether having thinning, variable color, layering and firmness change, with the cold tolerance of judgement sample after recovering room temperature;
Centrifugal test: sample is placed in centrifuge, with the speed test 30min of (2000 ~ 4000) r/min, observes the separation of sample, point layer status.
Result is as shown in table 2 and table 3.
Table 2 formula of bath cream stability test result
Table 3 shampoo formula stability test result
As can be seen from table 2 and 3 result, the formula 1 ~ 8 containing the gentle surfactant system prepared by the present invention is all stable; And in comparative formula, there are the factors of instability in heat stability or freeze-stable.
