I-75% yotywala isetyenziswa ngokuqhelekileyo ezibhedlele kwaye inokubulala i-Escherichia coli, i-Staphylococcus aureus, i-Candida albicans, i-Pseudomonas aeruginosa, njl njl. Ikwasebenza ngokuchasene ne-coronavirus entsha.Umgaqo we-disinfection wotywala ngolu hlobo lulandelayo: ngokungena ngaphakathi kwibhaktheriya, ifunxa ukufuma kweprotheyini ukuyikhupha, ukuze kufezekiswe injongo yokubulala ibhaktheriya.Ngoko ke, utywala kuphela obunogxininiso lwe-75% lunokubulala ngakumbi ibhaktheriya.Ugxininiso oluphezulu kakhulu okanye oluphantsi kakhulu aluyi kuba nefuthe le-bactericidal.
Amayeza okubulala iintsholongwane enziwe ngotywala nawo aneengxaki ezithile, njengokuguquguquka kwawo, ukutsha, kunye nevumba elibi.Ayifanelekanga ukusetyenziswa xa ulusu kunye ne-mucous membranes zonakaliswe, kwaye abantu abangahambisani notywala nabo banqatshelwe ukuyisebenzisa.Ngoko ke, kwi-alcohol wipes, ngenxa yokuba utywala buyaguquguquka kwaye ugxininiso luyancipha, luya kuchaphazela umphumo we-sterilization.Utywala buyanciphisa kwaye buyacaphukisa ulusu, nto leyo inokukhokelela ngokulula kolusu olomileyo kunye nokuxobuka.
