As can be seen from Table 7, embodiment 21-28 is in high temperature (40 DEG C and 48 DEG C), low temperature (4 DEG C and -15 DEG C), room temperature
(25 DEG C), the stability under illumination and cycling condition is good, does not occur oil droplet floating or sinkage in system；Wherein,
Under the conditions of centrefuge experiment (rotating speed 1000,30 minutes time), do not occur oil droplet floating or sinkage yet, have good stability.
Experiment proves that the water-based structure-solution of the low viscosity of the present invention has good suspension stability, is controlling water phase and an oil phase density
Under conditions of, can suspend grade oil droplet well, obtain the stable water-based knot of microgel comprising low viscosity of the present invention
Mosquito repellent/anti-pruritic compositions of structure solution
Lamination occurs in high temperature circulation and illumination in comparative example 3 and 4.
Test case 2：The mosquito repellent test of pesticide effectiveness
Method of testing：GB/T13917.9-2009
Test sample：Embodiment 21-24 mosquito repellent compositions
Subjects：Sensitive aedes albopictus (Aedes albopictus), the female insect that emergence is not sucked blood for 3-5 days；Come
Source：The sensitive strain of Shanghai plant physiological ecology research institute of Chinese Academy of Sciences laboratory Long-term breeding.
Temperature：26 ± 1 DEG C, relative humidity 65 ± 10%
Mosquito cage：The high 300mm of the long wide 300mmX of 400mmX
Attack is tested：300 test worms, tester's the back of the hand exposure 40mmX 40mm skins, its remaining part are put into mosquito cage
Divide tight masking.Hand is stretched into mosquito cage and stopped 2 minutes, close observation, it is found that mosquito stops falling, before its mouthpart will be pierced into skin
Shake arm is expelled, and is designated as 1 test worm and is stopped falling.Tester and the test worm that the test worm for coming to stop falling is more than 30 are attack
Power is qualified, and this person and this cage mosquito can carry out repellent experiment.
Repellent is tested：Selecting the qualified tester of 5-7 name attacks, (men and women half and half, and before testing and during experiment not
Drink, tea or coffee, the product of the class containing essence should not be used), 50mmX 50mm skin area is respectively drawn in its both hands the back of the hand,
A wherein hand smears culicifuge to be measured by 1.5 μ L/cm2 dose uniformity, exposes 40mmX 40mm skins therein, tightly
Remainder is covered, another hand is blank control.Smear culicifuge 2 hours, hand is stretched into the qualified mosquito cage of attack 2 points
Clock, observation, which whether there is mosquito, is come to stop to fall to suck blood.Afterwards at interval of test in 1 hour once, as long as there is a mosquito to come to suck blood i.e.
Sentence and make repellant failure.Record the effective protecting time (hour) of repellant.Control hand first does check experiment every time, and attack closes
The test worm of lattice can continue to test, and test worm attack is unqualified, need to change qualified test worm and tested.
Result of the test
| Test sample | Effective repellent time (hour) |
| The mosquito repellent composition of embodiment 21 | 6.33 |
| The mosquito repellent composition of embodiment 22 | 6.14 |
| The mosquito repellent composition of embodiment 23 | 6.28 |
| The mosquito repellent composition of embodiment 24 | 6.17 |
Effective repellent time of embodiment 21-24 mosquito repellent compositions is all higher than 6 hours, with reference to GB/T13917.9-2009
《Agriculture chemical registration hygienic insecticide indoor pharmacodynamic test method》The evaluation criterion of middle pharmacodynamics index, effective repellent time >=6 are small
When be A levels, it is possible to determine that the preparation-obtained mosquito repellent compositions of 21-24 of the embodiment of the present invention have reached A level product, can reach
Effective repelling effect.Test case 3：Antipruritic experiment
Test material：
Animal：Cavy 110 (every group 10) body weight：300g or so is female/the limited public affairs of the male dry biotechnology of half and half Shanghai first
Department
Histamine phosphate：National Institute for Food and Drugs Control
Positive control：Dexamethasone (30g:22.5mg) three nine-day periods after the winter solstice pharmaceutical sector
Sample：Embodiment 25-28 anti-pruritic compositions
Experimental condition：Laboratory temperature：20-25 DEG C of relative humidity：60-70%
Test method：
Cavy is randomly divided into 8 groups, every group 10.Divide blank control group, positive controls, three groups of sample.Before experiment
One day, to instep behind each group cavy right side, apply sample once.Experimental day, at instep shaving behind the coarse sandpaper scratch animal right side, about
1 square centimeter of scope or so, then smear sample once in this place, blank control group gives equivalent distilled water.After waiing upon 10 minutes, open
Begin in the histamine phosphate 0.05ml/ of wound face Chu Di 0.01% only, hereafter to press 0.01%, 0.02%, 0.03% every 3 minutes,
0.04%...... progressive concentration, it is 0.05ml/ every time.Until cavy occur later licks right metapedes, finally to there is globefish
It is itch-threshold that mouse, which turns one's head to lick the histamine phosphate total amount given during right metapedes,.Record and compare the itch-threshold of each group.
Result of the test：
Embodiment 25-28 anti-pruritic compositions cause the influence of reaction of itching to histamine phosphate
*：P values are test group compared with blank control group
Compared with blank control, embodiment 25-28 anti-pruritic compositions be improved cavy itch-threshold effect (P<0.01), have
Obvious antipruritic effect.
Although having been given and describing typical embodiment, those skilled in the art will be understood that, not depart from
, can be to the various changes in its form and details in the case of the scope of the invention defined by the claims.
