How do antiseptics differ from disinfectants? When it comes to household cleaners, customer choices are vast and confusing.
What’s the difference between antiseptics, sanitisers and disinfectants? To which use should you apply each of them?
Cleaning your home is essential for a healthy environment but there are so many products on the market it can be overwhelming.
Consumer education about the differences between these cleaning agents is vital as incorrect use could lead to health risks.
Knowing how antiseptics differ from disinfectants provides an opportunity to make better decisions about what cleaning substances to use in different situations.
In this article, we will discuss why antiseptics have different properties than disinfectants in terms of biological efficacy and safety in use.
How do Antiseptics Differ from Disinfectants
Antiseptics and disinfectants are two agents used to kill germs and bacteria that can cause diseases.
Antiseptics are used directly onto human skin, while disinfectants are for surfaces.
Here’s a quick look at how antiseptics differ from disinfectants:
Definition of Antiseptics
Antiseptics are substances that are applied directly to living tissue to slow or stop bacterial growth and to fight infection.
They are generally safe enough for use on cuts, scrapes, and other forms of wounds.
An example is hydrogen peroxide, which works as an antiseptic via oxidation process that destroys cell wall of bacteria.
Definition of Disinfectants
Disinfectants are highly concentrated chemical agents that eliminate microorganisms from non-living surfaces, such as desks, countertops, floors, sinks, toilets, door knobs and much more.
Commonly used disinfectants include bleach (sodium hypochlorite) and lactic acid.
The active ingredients in these products create a hostile environment for microbial survival by destroying their cell walls or disrupting their metabolic processes.
Mode of Action
Antiseptics work by killing bacteria on the surface of the skin, preventing it from entering deeper tissue layers.
They may also inhibit growth or production of certain enzymes necessary for bacterial survival, thereby reducing the risk of infection.
Disinfectants, on the other hand, work by destroying both living and dead microorganisms, such as fungi and parasites that may be present on inanimate objects or surfaces.
The mode of action differs depending on the type of antiseptic or disinfectant being used.
The concentration range is one way to differentiate between antiseptics and disinfectants.
Antiseptic solutions typically have a lower concentration range than disinfectants which makes them safer to use on human skin.
Antiseptic solutions usually contain no more than 2 percent active ingredients whereas some types of disinfectants can have active ingredient concentrations as high as 20 percent or higher depending on the type being used.
Another difference is that there are many different types of antiseptics and disinfectants available such as ethanol-based solutions, hydrogen peroxide-based products, quaternary ammonium salts (QUATs), sodium hypochlorite (bleach) solutionand chlorhexidine gluconate (CHG)-based products among others.
Each type has unique properties that make it suited for specific applications such as cleaning hard surfaces , sterilizing equipmentor treating wounds .
The way each product is used also differs .
Antiseptics should be applied directly to open wounds directly to skin where organisms can enter while disinfectants should only be applied to inanimate objects and surfaces with enough force so that they reach any nooks and crevices where germs might lurk such as in tile grout joints or around countertops edges.
Differences in Safety
When applied to living tissues, antiseptics can cause harm if they enter the bloodstream or other areas not intended for treatment, therefore it’s important to follow directions carefully when using antiseptic products on open wounds or mucous membranes to minimize side effects.
On the other hand, although disinfectants can be very strong chemicals that require caution during use, they are designed specifically for surface applications and generally do not penetrate deep enough into the skin tissue to cause harm if contact occurs with small amounts of these chemicals due to accidents.
Do not forget about storage requirements either – some antiseptics like alcohol-based solutions need to be refrigerated due to their short shelf life whereas certain types of liquid chlorine bleach can last up to 12 months if stored properly at room temperature making these a better choicefor longer term use like in public swimming pools or janitorial supplies closets outside healthcare settings neat hospitals.
Antiseptics and disinfectants both have important roles to play in keeping people safe from disease-causing agents.
While antiseptics are designed to kill microorganisms directly on the skin or other surfaces, disinfectants are used on non-living objects, like floors or countertops.
Each works differently, but they are both integral parts of protecting your health and that of others around you.
