Description
技术领域
本发明属于抗菌技术领域,具体涉及一种抗菌用银离子化合物,还涉及一种无刺激性银离子抗菌剂及其制备方法、应用。
背景技术
消毒抗菌制品能够有效杀死自然界中有害细菌、真菌和病毒等微生物,有效保障了人类的健康,因此消毒抗菌制品已成为人民生活中不可缺少的一部分。消毒抗菌制品按照自然属性可以分为天然抗菌剂、有机抗菌剂和无机抗菌剂。银离子具有极强的杀菌性能,并且对人毫无伤害,因此银系杀菌剂是一种常用的无机杀菌剂。银系抗菌剂中银有纳米银单质和银离子两种存在形式,其中纳米银单质同样是通过转化为银离子来发挥抗菌作用的,因此当银以银离子形式存在时抗菌效果较好。
目前,银离子的来源基本都是硝酸银的水溶液,有些简单的银离子抗菌剂是直接以硝酸银溶液为原液制成。以硝酸银为原料制成的银离子抗菌剂,存在以下问题:硝酸银不稳定,在久置后会发生分解反应从而使得银离子的抗菌效果降低;硝酸根对皮肤具有刺激性,对伤口愈合也不利,不利于在护肤化妆品中的应用。另外,含有银离子的抗菌剂应用在凝胶、敷料以及织物中形成抗菌产品时,在紫外线照射下银离子易被还原形成黑色银沉淀,不仅影响外观更影响抗菌效果。
为提高银离子的稳定性,常采用氨水与硝酸银形成银氨络合离子,但是银氨络合离子的氨味重并且耐盐性差;目前市场上出现了无硝酸根的电解银抗菌剂,但是其中银离子浓度较低,抗菌效果较差。
发明内容
本发明的目的在于提供一种抗菌用银离子化合物,该抗菌用银离子化合物具有较好的稳定性并且无刺激。
本发明的目的还在于提供一种无刺激性银离子抗菌剂,该抗菌剂无刺激并且具有较好的抗菌效果。
本发明的目的还在于提供一种上述无刺激性银离子抗菌剂的制备方法。
本发明的目的还在于提供一种上述无刺激性银离子抗菌剂在护肤化妆品中的应用。
为实现上述目的,本发明采用的技术方案为:
一种抗菌用银离子化合物,其阳离子为银离子和氨基酸配体形成的配位阳离子,所述氨基酸配体选自氨基酸和/或多肽,阴离子选自乙酸根、磷酸氢根、磷酸二氢根、甘油磷酸氢根、甘油磷酸根、乳酸根、乙醇酸根、酒石酸根、柠檬酸根、苹果酸根中的一种或多种。

另外,在抗菌液中还可以添加起一些现有的抗菌液常用的添加剂如乙醇、过氧化氢、过氧乙酸等物质。
优选的,本发明的无刺激性银离子抗菌剂为抗菌凝胶,抗菌凝胶包括凝胶载体和负载在凝胶载体上的活性成分,其中凝胶载体主要由水溶性高分子形成,活性成分即为本发明的抗菌用银离子化合物。
