Disclosure of Invention
The invention aims to provide the pet shampoo with the effects of expelling parasites, removing smell and inhibiting bacteria, and the pet shampoo has good effects of expelling parasites, removing smell and inhibiting bacteria, is low in irritation and is safe to pets.
The aim of the invention is achieved by the following technical scheme:
a pet shampoo with effects of expelling parasite, removing odor and inhibiting bacteria comprises amphoteric surfactant, nonionic surfactant, insect repellent, deodorant, oil and fat, and antiseptic; the insect repellent is a pesticideAn alkane-3, 8-diol; the deodorant has the following structure:
wherein R is 1 Is C14, C16, C18 or C20 alkyl, R2 is methyl, ethyl or propyl, R 3 Is methylene, ethylene or propylene.
The invention aims to obtain the pet shampoo with effective insect expelling, smell removing, bacteriostasis and low irritation:
firstly, the pet shampoo is compounded by adopting insect repellent and deodorant, so as to achieve the purposes of expelling insects and removing peculiar smell; wherein, toThe alkane-3, 8-diol (CAS number 42822-86-6) can act on lice, fleas, mosquitoes, nasal discharge insects, armyworms and the like as an insect repellent, and has long effective acting time; the deodorant is sulfuric acid ester or phosphoric acid ester with a specific structure, the property is stable, quaternary ammonium salt cationic groups in the structure have positive charges, and nitrogen or sulfur atoms in odor molecules contain lone pair electrons, so that the deodorant can attract odor molecules and combine with the odor molecules to achieve the effect of rapid and stable deodorization; furthermore, the inventors have found that the deodorant has a certain bacteriostatic effect in the system.
Meanwhile, through continuous researches of the inventor, the insect repellent and the deodorant are matched and applied to a formula system of the pet shampoo, so that the insect repellent and the deodorant have the effects of removing peculiar smell and expelling insects, and can achieve unexpected antibacterial effect in a synergistic way when being matched and used, and the effects of removing peculiar smell and expelling insects of the formula are further improved.
Through the research of the inventor, the reason why the insect repellent and the deodorant can synergistically improve the deodorizing, insect repellent and antibacterial effects of the pet shampoo is presumed to be as follows: 1. the deodorant is characterized in that a negatively charged sulfate group or phosphate group is present, and is opposite toThe hydroxyl of the alkane-3, 8-diol acts to form a larger molecular structure, and the macromolecular structure has stronger cell membrane penetrating capacity to bacteria and reactivity to odor molecules than any component alone, so that better antibacterial effect and odor removal effect are generated; 2. the deodorant reacts with odor molecules on pet body surface to relieve pet odor, and relieve +.>The alkane-3, 8-diol can more effectively exert the repellent effect of the smell on insects.
Furthermore, the inventor strictly controls the irritation of the formula from the aspect of the design of the whole formula; the PMD which has the same insect repellent effect as the mosquito repellent amine and is only one sixth of the mosquito repellent amine in toxicity is selected, and is a non-pesticide component, is the only natural active component of the insect repellent allowed to be used in the United states and European Union, and is safe and reliable; surfactants with low irritation are also used. The deodorant disclosed by the invention is nontoxic, has the characteristics of stable illumination performance, difficult yellowing, strong compounding capability and the like compared with the existing deodorant, and can be applied to an anionic surfactant system, a cationic surfactant system and a nonionic surfactant system.

2. And (3) deodorizing effect test:
the testing method comprises the following steps: the deodorizing performance of the washed fabric is tested by taking ammonia gas as odor, the fabric material is selected from rabbit hair or wool, the washing method is according to 10.1.1 in standard GB/T20944.3-2008, the detergent adopts the formula of the pet shampoo listed in the example, and the concentration of the detergent is 20g/L. The fabric was cut into a round shape with a diameter of 4cm, 0.1mL of ammonia water was sucked up on a glass dish, the glass dish was placed at the bottom of the dryer, the fabric was placed on a tray of the dryer, ammonia was sucked up for 14 hours, and after the ammonia suction was completed, 100.0mL of distilled water was used for extraction at 40℃for 2 hours. The ammonia content in the extract was measured using HJ 534-2009 "determination of ambient air ammonia sodium hypochlorite-salicylic acid spectrophotometry", and the deodorizing ratio of the washed fabric was indirectly obtained by dividing the difference between the unwashed fabric and the adsorbed ammonia on the washed fabric by the difference between the total ammonia amount and the adsorbed ammonia on the unwashed fabric, and the results are shown in table 8.
Deodorization efficiency = (ammonia adsorbed on fabric after washing-ammonia adsorbed on unwashed fabric)/(total ammonia amount-ammonia adsorbed on unwashed fabric) ×100%

3. Mosquito repelling rate test
Reference standard GB/T13917.9-2009 "pesticide registration hygienic pesticide indoor efficacy test and evaluation part 9: repellent(s);
test insects: aedes albopictus (Aedes albopictus), female adults that did not draw blood 4-7 days after eclosion;
test conditions: the temperature is 25+/-2 ℃ and the relative humidity is 60-70%;
the test method comprises the following steps: 4 qualified testers were selected, and a 50mm by 50mm skin area was circled on each of their backs, one hand was washed at a sample concentration of 10% by mass, and washed clean, air-dried naturally, exposing 40mm by 40mm skin, and closely covering the rest, the other hand being a blank. Immediately after air-drying, the repellency test was performed. Each tester firstly puts the control hand into the mosquito cage, immediately counts time, records the stopping number of mosquitoes and tests for 5 minutes. Then the tester puts the hand washed by the sample into a mosquito cage, tests the hand in the same way and records the stopping number of mosquitoes. The repellency was calculated from the repeated test data as follows, the results are shown in Table 9: p= (N-K)/nx100%
Wherein P is the repellent rate,%; n is the total stopping number of the control hand mosquitoes, and the unit is 'only'; k is the total number of hand and mosquito stopping after sample washing, and the unit is "only".
