Disclosed are pressurized surface treatment compositions which impart a microbicidal benefit to treated surfaces which compositions comprise (or in certain preferred embodiments may consist essentially of, or may consist of): a zinc ion source material which releases zinc ions into the treatment composition, preferably a source of Zn++ ions, at least lower alkyl aliphatic monohydric alcohol which independently of other constituents present exhibits a microbicidal effect, a propellant; and, water. The compositions may further optionally include one or more further optional constituents such as a detersive surfactant and/or minor amounts of one or more constituents which impart one or more advantageous technical or aesthetic benefits to the compositions, including one or more detersive surfactants wherein the compositions have pH of at least 5. The compositions exhibit a microbicidal or germicidal or antimicrobial effect on treated inanimate surfaces and are characterized in exhibiting a microbicidal benefit when tested against one or more challenge microorganisms, preferably against poliovirus type 1 (Sabin) [“PV1”], according to one or more of the following standardized test protocols: ASTM E1052 Standard Test Method for Efficacy of Antimicrobial Agents against Viruses in Suspension, or ASTM E1053 Standard Test Method to Assess Virucidal Activity of Chemicals Intended for Disinfection of Inanimate, Nonporous Environmental Surfaces, or European Standard Surface Test, EN13697, or AOAC Germicidal Spray Products as Disinfectant Test Method, AOAC Index, 17th Ed. (2000).
本发明公开了加压表面处理组合物,该组合物对处理过的表面具有杀菌作用,该组合物包括(或在某些优选的实施方案中基本上包括,或可能包括):锌离子源材料,该材料将锌离子释放到处理组合物中,优选的是Zn++离子源;至少低级烷基脂肪族一元醇,该醇类与存在的其他成分无关,具有杀菌作用;推进剂;以及水。组合物还可进一步包括一种或多种可选成分,如阻垢性表面活性剂和/或少量可赋予组合物一种或多种有利的技术或美学益处的一种或多种成分,包括一种或多种阻垢性表面活性剂,其中组合物的 pH 值至少为 5。根据以下一种或多种标准化测试协议,这些组合物在经过处理的无生命表面上具有杀菌、抑菌或抗菌效果,其特点是在针对一种或多种挑战微生物(最好是针对 1 型脊髓灰质炎病毒(Sabin)["PV1"])进行测试时具有杀菌效果:ASTM E1052《抗菌剂对悬浮液中病毒的效力标准测试法》,或 ASTM E1053《评估用于无生命、无孔环境表面消毒的化学品杀病毒活性的标准测试法》,或《欧洲标准表面测试》,EN13697,或《AOAC 杀菌喷雾产品作为消毒剂的测试法》,AOAC 索引,第 17 版(2000 年)。
