摘要
以肉桂为原料,通过水蒸气蒸馏法制备肉桂提取液,研究其抗菌效果,并开发肉桂洗洁精。通过抗菌试验测定肉桂提取液对大肠杆菌及空气中杂菌的抑制作用;以去污力和抗菌率为指标,优化肉桂洗洁精的配方。结果表明:肉桂醛质量分数为758和75.8 mg/kg的肉桂提取液的抗菌效果较好,对大肠杆菌、空气中杂菌均有良好的抑制效果。优化的洗洁精配方为:肉桂提取原液质量分数15%,表面活性剂脂肪醇聚氧乙烯醚、十二烷基苯磺酸钠和脂肪醇聚氧乙烯醚硫酸钠的质量分数分别为6%,8%和9%。与市售的洗洁精相比,含15%肉桂提取原液的肉桂洗洁精抗菌效果较强。
Cinnamon extract was prepared by steam distillation from cinnamon,and its antibacterial effect was studied for developing the cleanser essence. The antibacterial effects of cinnamon extract on colibacillus and airborne bacteria were determined by bacteriostatic test,and the recipe of cleanser essence was optimized with detergency and antibacterial rate as indicators. Results show that cinnamaldehyde mass fraction of 758 and 75. 8 mg/kg of cinnamon extract is significant,and they show certain antimicrobial activity on colibacillus and airborne bacteria. The optimized cleanser essence formulation is as follows: the mass fraction of cinnamon extract is 15%,the mass fraction of surfactants fatty alcohol polyoxyethylene ether is 6%,dodecyl benzene sulfonate is 8%,and fatty alcohol polyoxyethylene ether sulfate is 9%. Compared with the commercially available cleanser essence,the cleanser essence containing 15% cinnamon extract has stronger antibacterial effect.
