摘要
为了制备含十二烷基二亚丙三胺(DDT)抗菌成分的洗手液,以AES-6501-NaCl、CAB-35-AES-NaCl、丙烯酸-2-丙烯酰胺-2-甲基丙磺酸、6502-NaCl(Na_(2)SO_(4))和聚乙二醇6000双硬脂酸酯(638)系统为研究对象,在这些体系中分别加入等质量分数的DDT,以体系的黏度与透光率为指标,来判断增稠体系与DDT的兼容性强弱。在此基础上,进一步进行单因素试验,优化洗手液的配方,制备出含DDT抗菌成分的洗手液。再对制得的洗手液进行了性能检测,包括稳定性、黏度、活性物含量、pH值、起泡高度及杀菌性能。实验结果表明:除638体系与DDT有一定兼容性外,其余增稠体系兼容性皆较差。制得的含DDT抗菌成分的洗手液各项性能指标均符合国家标准,且该复配洗手液在2 min的作用条件下对大肠杆菌、金黄色葡萄球菌平均杀菌率分别达到97.63%和98.96%。
The hand sanitizers containing dodecyl dipropylene triamine(DDT,antibacterial component)were prepared with the thickening systems such as AES-6501-NaCl,CAB-35-AESNaCl,acrylic acid-2-acrylamide-2-methylpropanesulfonic acid,6502-NaCl(Na_(2)SO_(4)),and polyethylene glycol 6000 distearate(638).The same mass fraction of DDT was added to these systems respectively.Then the viscosity and transmittance were investigated to judge the compatibility of these thickening systems with DDT.Single factor experiments were further carried out and the formula was optimized.The hand sanitizer containing DDT was thus prepared.Then the properties of the hand sanitizer were tested,including stability,viscosity,active substance content,pH value,foam height and bactericidal performance.The experimental results show that,the 638 system is compatible with DDT,while other thickening systems are not compatible with DDT.After high-temperature and lowtemperature stability tests,the antibacterial hand sanitizer containing DDT shows no phase separation,no precipitation and no obvious color change,indicating that it has good stability.The viscosity is 2767 Pa·s,which proves that the hand sanitizer can stay on the skin for a long time.The average value of active substance content is 10.2%and the pH value is 5.5,which all meet the national standard.The average bactericidal rates of the hand sanitizer against Escherichia coli and Staphylococcus aureus in 2 minutes were 97.63%and 98.96%,respectively.
