Sodium Benzoate & Citric Acid Myth
Written by Irina Webb
Have you ever scanned the ingredient list on a skincare product and wondered if the combination of citric acid and sodium benzoate could be harmful? I had that exact question back in 2012, when I was researching baby shampoos to find the safest option for my son. That moment actually marked the beginning of my journey as a product researcher. One concern that keeps popping up online is whether citric acid and sodium benzoate, when used together in personal care products, can form benzene—a known carcinogen. Understandably, that sounds alarming. But is it true? In this ingredient review, I’ll dive into the science, separate fact from fear, and give you clear, trustworthy guidance to help you navigate ingredient labels with more confidence.
Unraveling The Sodium Benzoate & Citric Acid Myth
If you’ve ever scanned the ingredient list on a baby wipe pack, face cleanser, or lotion and paused at citric acid and sodium benzoate—you’re not alone. There’s a lot of online buzz suggesting these ingredients, when used together, can form benzene, a known carcinogen. But how true is that, and should you worry if your skincare products contain both? Let’s look at what the science really says.
To begin with, sodium benzoate, the sodium salt of benzoic acid, is a common preservative in food, cosmetics, and personal care products. Due to its antimicrobial properties, especially against fungi, it is effective and generally safe (source).
Next, citric acid is a weak organic acid abundant in citrus fruits. In food and beverages, citric acid functions as an acidifier, flavoring agent, preservative, and chelating agent. It is generally recognized as a safe (GRAS) direct food additive. In cosmetics and baby wipes, it is used in very small quantities primarily as a pH adjuster and doesn’t cause any concerns, especially if a non-GMO version is used (source and source).
Understanding Benzene Formation Concerns
Benzene is a known human carcinogen, commonly found in crude oil, gasoline, and cigarette smoke, and may form during certain industrial or environmental processes (source and source).
Concerns over benzene in consumer products first emerged in the early 1990s when some soft drinks tested positive for benzene, especially when they contained sodium benzoate and ascorbic acid (vitamin C) and were exposed to heat, light, and metal ions (e.g., copper, iron) (source). The FDA and the American Beverage Association addressed this issue in the mid-2000s, prompting reformulations of beverages and revised manufacturing guidelines (source).
In 2006, the American Beverage Association issued guidelines to help beverage manufacturers reduce or eliminate benzene formation in soft drinks that contained both benzoic acid and ascorbic acid. The key recommendations included reformulating products by replacing ascorbic acid, adding chelating agents like EDTA to inhibit catalysts, and controlling storage conditions to limit heat and UV exposure.
Sodium Benzoate + Ascorbic Acid = Potential Benzene Formation
There are studies confirming that the reaction between sodium benzoate and ascorbic acid (Vitamin C) can lead to the formation of benzene.
For instance, in this study, researchers tested 25 popular Ayurvedic health supplements, containing ascorbic acid and sodium benzoate preservatives, and found that 36% had some benzene in them. While all the products had benzene levels within safety limits, its presence in supplements meant for daily use is still concerning.
Next, this study examined 28 drinks that tested positive for trace amounts of benzene, with higher levels found in those containing both sodium benzoate and ascorbic acid.
Further, this study found that while some benzene occurred naturally in foods like eggs and butter, higher levels appeared in products that included both benzoates and ascorbic acid.
Note that the studies above discovered the benzene formation mechanism when sodium benzoate reacted with ascorbic acid, not citric acid. By the way, despite both being acids found in many fruits, citric acid and ascorbic acid are not similar, have distinct roles and functionalities, and cannot be used interchangeably.
Sodium Benzoate + Citric Acid = No Benzene Risk
First off, citric acid is a tricarboxylic acid with three carboxyl groups. Ascorbic acid, on the other hand, is a lactone and is related to glucose. Due to its stronger acidic properties, citric acid primarily functions as pH regulator, preservative, and flavoring agent. Conversely, ascorbic acid, a vital nutrient and antioxidant with immune-supporting properties, works well for antioxidant protection, immune support or color preservation (source and source).
That said, I made sure to thoroughly research whether combining citric acid with sodium benzoate could lead to benzene formation in food or cosmetic products. I found no evidence to support that claim. On the contrary, the studies I came across highlight the positive role citric acid plays in these products, with several environmental studies even showing that citric acid helps break down benzene or prevent its formation altogether.
Food Preservation Studies With Citric Acid
First, this study tested a new way to concentrate blueberry juice without heat, using common food additives like citric acid, sodium benzoate, and potassium sorbate as part of the process. Citric acid stood out as the most effective, helping preserve more antioxidants (like anthocyanins and phenolics) and keeping the juice stable during processing and storage. In other words, far from being harmful, citric acid plays a supportive and protective role in maintaining the quality of food products. (More on polyphenols in my post Are There Polyphenols In Olive Oil?.)
Second, this study looked at how different additives, including citric acid and sodium benzoate, affect the shelf life, safety, and quality of cucumber juice. Citric acid helped preserve the juice naturally by enhancing antioxidant activity and maintaining flavor, while sodium benzoate was more effective in improving color, taste, and microbial control. To put it another way, citric acid proved to be a valuable natural preservative that supports both the nutritional quality and sensory appeal of the juice without relying on synthetic additives.
Third, this study tested ways to make orange-fleshed sweet potato puree last longer by using a mix of preservatives and citric acid. It found that combining potassium sorbate, sodium benzoate, and citric acid significantly reduced harmful bacteria like E. coli and Staphylococcus aureus, while also preventing mold and yeast growth. That is to say, citric acid played a key role in enhancing the safety and shelf life of the puree, making it a reliable component in natural food preservation.

Environmental Studies With Citric Acid
Next, this study explored how different amounts of citric acid used in making manganese oxide affect its ability to break down benzene. The 2:1 citric acid to manganese nitrate ratio worked best, breaking down 90% of benzene at just 212°C, turning it into harmless carbon dioxide and water through a series of chemical steps. To rephrase, citric acid significantly enhanced the effectiveness of the catalyst, playing a crucial role in promoting a cleaner, more efficient way to remove toxic pollutants like benzene.
Furthermore, researchers in this study added citric acid to gasoline-contaminated soil and discovered that phosphorus levels in the soil and water increased while harmful gasoline-related chemicals (like benzene and toluene) decreased. The results suggest that citric acid can boost microbial activity and speed up the natural breakdown of gasoline constituents in challenging soil conditions. In simpler terms, citric acid helped improve the natural cleanup process, making it easier for microbes to break down harmful chemicals, like benzene, in the soil.
Lastly, this study explored how to use persulfate to break down harmful gasoline compounds in water and soil. Among several additives tested, citric acid was the most effective, allowing complete degrading of benzene in just 70 minutes. So, essentially, citric acid helped break down toxic chemicals faster, making it a useful ingredient for cleaning up gasoline pollution.
Is Citric Acid Harmful?
I’ve been asked many times about citric acid in skincare products, with some genuinely seeking my perspective, and others challenging me, often citing vague claims like “so-and-so said it’s harmful.” I often find myself having to back up my views with scientific evidence, while those opposed offer no credible references. Interestingly, their audiences rarely ask for proof—they simply accept what they read or hear at face value. Meanwhile, I take time to research and base my opinions on reliable sources, as I believe informed discussion is crucial.
So, here’s a tip: next time you encounter alarming claims, pause and ask for sources or, simply put, ask them how they know that what they say is true. Are there peer-reviewed studies, regulatory information or any other grounds for reasonable assumptions? In my experience, when I ask bloggers for supporting evidence, I get no reply. It seems that a lot of the “knowledge” on the Internet comes from influencers blindly copying each other’s work.
It’s also important to remember that stress and worry can be far more harmful than trace amounts of ingredients or contaminants in skincare. If striving for “toxic-free” living causes you constant anxiety, it could be doing more harm than good. True wellness involves balance—physically, mentally, and emotionally.
To sum up, I believe the combination of citric acid and sodium benzoate is safe and effective, as supported by studies showing their role in food preservation without causing harm. In my opinion, these ingredients are not suspect for benzene formation, and citric acid even helps break down benzene in environmental studies, proving its safety and positive effects.
Conclusion: Do You Need To Worry About Sodium Benzoate And Citric Acid In Skincare Products?
I Haven’t Found Any Evidence That Citric Acid And Sodium Benzoate Together Form Benzene In Food Or Skincare Products.
In conclusion, based on scientific evidence, the reaction that forms benzene in products involves sodium benzoate and ascorbic acid, not citric acid, and typically requires high heat, UV light, and metal contaminants.
Because you apply some personal and skin care products regularly to large areas of skin or use them on infants, I would avoid using formulations containing both ascorbic acid and sodium benzoate. This is particularly true of the product stored in warm environments or packaged in materials that allow UV exposure.
That said, I would like to emphasize that it is okay to use products with ascorbic acid (Vitamin C) and sodium benzoate used separately. Indeed, sodium benzoate is a generally recognized as a safe preservative (especially in comparison to methylisothiazolinone and formaldehyde-releasing preservatives). And Vitamin C is a nutrient that the body needs in small amounts to function and stay healthy. As an antioxidant, it helps prevent cell damage caused by free radicals and rejuvenate your skin.

Just found you blog, I found a produte Gooya marinade has sodium benzoate and edta with citric essence oils. My search has found nothing about these two together with citric acids. Along benzoate and citric asics are not good. Put with Edta? Edta is a good metal tetox and more. Bensese/ carcinogen/ be efected in a good way with edta?
Hi Carolinah! Our post is not about sodium benzoate and citric acid. It is about sodium benzoate and vitamin C combination. Citric acid is not vitamin C.
I am breastfeeding and very careful about what I put on and in my body. The one treat I allowed myself (with doctor’s OK) is an almost daily latte. I just discovered this place uses Torani vanilla syrup which has sodium benzoate and citric acid. I am panicking that I’ve inadvertently harmed my baby by drinking this regularly…
Hi, Ali! Our “Sodium Benzoate & Citric Acid Myth” blog post emphasizes in the introduction and conclusion that “Benzene may form only when sodium benzoate and ascorbic acid are present in the same product. It must be ascorbic acid for this to occur, NOT citric acid.” May we ask about the cause of your anxiety?
Thank you for this! I was afraid to drink my Aloe Vera juice because it contains Sodium Benzoate and Citric Acid. Thanks for clearing everything up!
Thank you for your kind feedback, Kaylee! You are very welcome!
Hello Irina!
I was so interested to read this article as I have been studying Sodium Benzoate and how it interacts with Ascorbic Acid for some time now. I’m a skincare enthusiast and I’ve been obsessed with ingredients for a while. I try my hardest to only use the purest products (no parabens, alcohols, overall harsh ingredients etc.) Thus, once I learned how the two ingredients (in the same formulation) could cause Benzene, I was FLOORED and I instantly put it on my list of bad ingredients (based on individualized situation), mainly because I use A LOT of Vitamin C (in the form of ascorbic acid) products daily. After doing some research I learned that not only do A TON of products contain Sodium Benzoate, but also ingredients like: Benzoic Acid and a number of other “Ben” ingredients (many having a Benzene ring in their core or makeup). I was overwhelmed by how many products I had to eliminate and even more alarmed by a few VITAMIN C products that had the both ingredients inside. All that being said, I would love to hear your thoughts on the following question: In your opinion should I be concerned about using products with Sodium Benzoate in them since I would more than likely follow up with an Ascorbic Acid product? Wouldn’t that be similar to mixing the two ingredients and creating the cocktail on the surface of skin that would be absorbed?
Any advice would be more than appreciated! I’ve been racking my brain over this question for the longest time and constantly eliminating products with Sodium Benzoate in them.
Thank you so very much for your time and assistance!
Hi, Brittany! Thank you for reaching out to I Read Labels for You! Good job with your healthy living journey! As for your question, we have talked to chemists and did research into scientific sources, but we have not found any evidence proving that benzene formation on the skin after the subsequent use of ascorbic acid is possible. We hope this helps!
Hello Maria!
Thank you, thank you, thank you so very much for your kind words and reply! This information definitely helps!!
I TRULY appreciate your time and assistance!!
Sincerely,
Brittany B.
Of course! You are so very welcome!
Hi Irina,
I was wondering, is there a concern for the combination of Ascorbyl Palmitate and Sodium Benzoate in skincare products? I was unable to find any research about this form of Vit C.
Hi, Raza! Thank you for the question! Ascorbyl Palmitate is a kind of Vitamin C, and we do not recommend the combination of Vitamin C with Sodium Benzoate. I hope this helps!
How about the sodium benzoate in novaferrum liquid iron supplements for kids? Pediatricians recommend taking novaferrum with vitamin c foods like oranges for iron absorption. Does the combination result in the formation of carinogenic benzene?

Ever since the reports of Benzene have been in suncreen, I’ve been on the look out for Sodium Benzoate everywhere!
Lately I’ve been using two Mario Badescu products and I’m a bit nervous they’re unsafe. Typically I use the Witch Hazel Toner, Cellufirm Drops and Vitamin C Serum – and they all have Sodium Benzoate. Although my skin has been looking *great* lately, I DEFINITELY do not want to continue usage if they’re cancer causing.
The product I guess I’m most concerned about is the Vitamin C serum? Here are the ingredients:
Propylene Glycol, Aqua (Water, Eau), Aloe Barbadensis Leaf Juice, Hexylene Glycol, Pentylene Glycol, Tetrahexyldecyl Ascorbate, 3-O-Ethyl Ascorbic Acid, PEG-25 Hydrogenated Castor Oil, PEG-40 Hydrogenated Castor Oil, Cucumis Sativus (Cucumber) Extract, Panax Ginseng Root Extract, Sodium Hyaluronate, Soluble Collagen, Lavandula Angustifolia (Lavender) Oil, Hydroxyacetophenone, Triethanolamine, Citric Acid, Potassium Sorbate, Caprylyl Glycol, Phenoxyethanol, Silver Citrate, Zeolite, Sodium Benzoate
What are your thoughts? Cease and desist?
Hi Emma! The product you mentioned contains ethoxylated ingredients, namely PEG-25 and PEG-40, that we do not recommend on our website. If you need a more detailed consultation, Irina will be happy to help you: https://ireadlabelsforyou.com/services/

For the Mad Hippie Vitamin C
Water Deionized, Vitamin C (Sodium Ascorbyl Phosphate), Alkyl Benzoate, Vegetable Glycerin, Water, Glycerin, Sodium Levulinate, Sodium Anisate, Clary Sage (Salvia Sclarea), Grapefruit (Citrus Grandis), Hyaluronic acid, Amorphophallus Konjac Root Powder, Aloe Barbadensis Leaf, Vitamin E (Tocotrienol), Ferulic acid, Chamomile Flower Extract (Recutita Matricaria), Sodium Phytate, Xanthan Gum, Hydroxyethylcellulose
Is this safe?
The 2nd ingredient is Sodium Ascorbyl Phosphate and the 3rd ingredient is Alkyl Benzoate, so high amounts of both. Reached out to the company and they said the Alkyl Benzoate is derived from coconut. Not sure if that makes a difference.
Thank you for this article! It’s wonderful 🙂

Hi, Marija: from the perspective of sodium benzoate and ascorbic acid interaction, I believe that this product is okay. ~Irina
Would the body shop strawberry shampoo be a problem cause it has strawberry juice and sodium benzoate and I’m guessing strawberry juice has Vit C.
Aqua/Water/Eau, Sodium Laureth Sulfate, Citric Acid, Cocamidopropyl Betaine, Ammonium Hydroxide, Sodium Chloride, Propylene Glycol, Parfum/Fragrance, Sodium Benzoate, Hexylene Glycol, Polyquaternium-10, Glycerin, Fragaria Vesca Juice/Strawberry Juice, Salicylic Acid, PPG-5-Ceteth-20, Aloe Barbadensis Leaf Juice Powder, Limonene, Sodium Acetate, Isopropyl Alcohol, Sodium Hydroxide, CI 14700/Red 4, CI 17200/Red 33.
That’s an interesting one. I am not so sure how much of that strawberry juice is actually in the shampoo and how much of vitamin C is preserved in the juice. But the way, this shampoo does not adhere to the safety standards that I set up for I Read Labels For You. ~Irina
Hi! Thank you so much for this, it’s been so helpful. Would taking an iron supplement with sodium benzoate and also eating vitamin c -rich foods to help with absorption be problematic?
Thanks,
Kathleen
Hi, Kathleen: I don’t recommend taking sodium benzoate internally. Could you find a supplement without sodium benzoate preservatives? ~Irina
Hello, i use sunscreen that contains benzoic acid, on mornings. İs it okay to use vitamin c on evenings after cleaning sunscreen from my face?
Yes, I believe so. ~Irina
Irina, what wipe preservative would you recommend in this case? I followed this article from your previous post on Phenoxyethanol – which is a common preservative,
Would sodium benzoate be alright i.e if not better than phenoxyethanol? Maybe the better question is what preserve should I look for in wipes?
Hi, KenStacey! I believe that sodium benzoate is safer than phenoxyethanol in baby wipes. Have you considered getting the Baby Wipes Rating List ebook? https://ireadlabelsforyou.com/ebooks/baby-wipes/ ~Irina
Hi Irina,
I was wondering, given more Vitamin C derivatives are now used in skincare some of them actually mix with sodium benzoate and/or benzoic acid with these latter being listed near the bottom of the list. Do you know if derivatives like ethyl ascorbic acid are safe to layer with other products containing them. Is there a skin reaction that occurs that makes us known to the danger? I’ve only used the derivative and have tried to research and most articles note that skin penetration has low risk for any danger.
Hi, Angela: I agree with you that the risks are very minimum. ~Irina
Is there a concern about products combining sodium benzoate with sodium ascorbyl phosphate?
And does this apply to C12-15 alkyl Benzoate? What about benzyl alcohol?
Thanks.
There is only concern when it is combined with a form of a vitamin C. ~Irina
Hi & thank you for such a clarifying post. If I’m understanding correctly, it would not be wise to mix a vitamin c serum – ascorbic acid as the active with a hydrating serum that contains sodium benzoate? This might create a “benzene situation?”
Thank you!
Yes, you are correct, Lena. Thank you for clarifying. ~Irina
Should I be concerned by the combination of sodium benzoate and E-ascorbic acid used in this product ?

Hi,
Im thinking of trying this product that has the following ingredients:
Triticum vulgare/aestivum (wheat) sprout extract, purified water, fructose, glycerol, sodium benzoate, potassium sorbate.
My question is that wheatgrass contains vitamin C and whether it is a concern since sodium benzoate is added in.
Thanks!
Lin
Hello Hui Lin! We appreciate your interest! Irina will be happy to help you with your question in a private consultation: https://ireadlabelsforyou.com/services/
Thank you for this, much appreciated!
This is such wonderful news. Thank you for this info Irina. It is invaluable! I have a query though, so one should stay away from personal care products with sodium benzoate & Vit C in it, but can you layer or use different products on let’s say your face where one contains Vit C and another sodium benzoate? 🤔
That’s a good point, Martie. Less is more. 🙂 ~Irina
So sodium benzoate is 100 % safe correct?
Especially in deodorants mixed with essential oils? Directly in contact with our lymph nodes.
Because essential oils do contain vitamin c.
I would just like to make sure.
I appreciate your help.
Stephanie: there is no such thing as 100% safe. What can be safe for one person can be poison for others. With this said. I don’t think there is any concern about mixing essential oils with sodium benzoate. ~Irina
