Is sodium benzoate the same as benzoyl peroxide?

Are you one of those people who stares at labels on packaged food like a sleuth examining crime scene evidence? If so, you’ve undoubtedly come across two ingredients: sodium benzoate and benzoyl peroxide. Both have long names that sound similar, but are they interchangeable? The answer might surprise you.

The Basics

First things first, let’s define what these two compounds actually are:

Sodium Benzoate

Sodium benzoate is a salt derived from benzoic acid that’s often used as a preservative in processed foods to prevent spoilage caused by bacteria or fungi. It works to slow down the metabolism of microbes.

What Foods Have Sodium Benzoate?

Sodium benzoate pops up frequently in soft drinks and fruit juices because it helps maintain acidity levels and prevents harmful yeasts from forming, ultimately extending shelf life span tremendously.

Benzoyl Peroxide

Benzoyl peroxide (BP or BPO) is an organic compound commonly found in personal care products such as acne treatments due to its antibacterial properties. This ingredient can kill Propionibacterium acnes bacteria dead with its preeminent oxidative characteristics.

Areas Benzoyl Peroxide Works Best:

It mainly operates in dry-cleansing operations for fabrics susceptible to be easily stained and worn out making them tear quickly. Feminine hygiene items also use this agent for bleaching purposes since it breaks down protein molecules very well.

You’re probably wondering why we need them anyway, though given our proclivity for processed goods nowadays I’m not surprised that curiosity isn’t high on your agenda- anywho enough stalling there Harold – back on track.

Are They Similar At All?

At first glance these chemicals appear completely different; after all one source claims that “sodium” makes great popcorn topping, and I assure you they’re not talking about benzoyl peroxide. However upon closer inspection we do begin to see some similarities emerge.

One common denominator between the two is their ability to kill bacteria which honestly deserve no less considering how our swollen size genes have grown over time- let’s just admit it those french fries of yours won’t be any good when plagued with mold. While they may take different forms – sodium benzoate in its salt form and benzoyl peroxide in a gel or cream – both are used for antimicrobial purposes.

Another similarity lies in their chemical makeup; while these compounds don’t look identical on paper, they are structurally related as both contain a benzene ring – bet you didn’t know that! Now don’t go bypassing your next chemistry class though solely based on this revelation

How Sodium Benzoate Works

Sodium benzoate would work on most fungi but so much revolved around acidity levels (our dear pH) and since Humans aren’t made up of single organisms like microbes,the addition of Sodium Benzoate to our systems could lead to adverse reactions especially if doses were higher than required thus sensible dosage consideration should always come into play during decision making.

While the primary goal is similar, what happens when these ingredients are consumed might surprise you.

What Happens When You Eat Them?

We covered the purpose behind using these chemicals but now lets dive deep into what happens once inside us beings where decisions such as double-fisting soda often end itself with feeling sheer regret.

The Fate of Benzoyl Peroxide

Benzoyl Peroxide comes from one family known as ‘Aryl ketones’ which make them capable oxidizing other molecules present within our bodies including bacterial membranes thereby defeating break out problems due excess accumulation leaving skin smooth for an entire day sometimes without requiring ointments maintenance..

Side Effects

However like any good thing, too much of anything can ruin the balance in our bodies and cause negative side effects such as over-drying skin or even contact dermatitis (no you don’t want that!).

What Sodium Benzoate Gets Up To

Sodium benzoate is more to do with preserving food for longer duration – this preservative prevents spoilage by altering metabolism rates of bacteria.

How It Affects Us Humans

When we consume packaged products laced with sodium benzoate, it converts into a gas called benzene which can lead to damage genetic materials harbored withincells precisely DNA . This ingredient could stop cell functions from operating normally essentially increasing risks for diseases on liver and kidney functioning eventually leading them to malfunction.

It’s important to note here that while both these chemicals work differently once inside us humans, they’re not interchangeable when it comes down what effect each would have.


In conclusion, despite having some similarities based off naming conventions and chemical structure outlines- the objectives behind sodium benzoate and benzoyl peroxide differ greatly. While one serves as an antimicrobial agent other preservatives foods thereby preventing mold development.

Both have essential roles but should be utilized sparingly lest unwanted consequences park gory results later so next time you get confused between those sound-alike toxic agents keep their differences in mind!
