Petrolatum: miracle moisturizer or toxic sludge? Let’s clear up the confusion once and for all.
Should You Be Worried About Petrolatum in Your Skincare?
Petrolatum (yes, the stuff in Vaseline) has recently gotten a bad rap. You may have noticed cosmetic labels proudly claiming “petrolatum-free” alongside “paraben-free” and “fragrance-free.”
But here’s the twist: my favorite diaper cream? Petrolatum-based. My go-to red lip balm? Also petrolatum. I even made my own diaper cream during the COVID shortage—true story.
So, what gives? Is petrolatum dangerous? Is it a miracle skin saver or just another petroleum byproduct to avoid?
Let’s break down the facts, fight the fear, and figure out once and for all if petrolatum deserves a spot in your skincare routine.
What Is Petrolatum?
Petrolatum (also called petroleum jelly or soft paraffin) is a semisolid mix of hydrocarbons derived from crude oil. It’s odorless, tasteless, and translucent, and it forms a protective barrier on the skin.
Fun fact: because it’s derived from crude oil (a natural substance), some brands even label it as “natural.” There’s no regulation on that term in cosmetics, so it’s fair game!
How Is Petrolatum Made?
Petrolatum comes from refining crude oil—the same stuff used for gasoline and diesel.
Here’s a simplified version:
- Crude oil is heated to over 1000°F in distillation towers
- Different parts evaporate at different temperatures
- Petrolatum is pulled from the waxes and lubricant fraction
- It’s then purified and hydrogenated to stabilize the molecules
- Proper refining removes impurities, including polycyclic aromatic hydrocarbons (PAHs)
So no, you’re not smearing gasoline on your face. This is a purified byproduct used safely in everything from skin creams to medical ointments.
Why Is Petrolatum Used in Skincare?
Because it’s amazing at what it does.
Petrolatum is:
- The most effective occlusive ingredient available
- Able to reduce water loss (TEWL) by up to 98%, even at just 5% concentration
- Long-lasting and inert, meaning it doesn’t react with skin
This is why it’s so often found in:
- Healing ointments (like Aquaphor)
- Lip balms
- Diaper creams
- Dry skin treatments
There are alternatives—but petrolatum remains the gold standard for locking in moisture and protecting the skin barrier.
Is Petrolatum Safe or a Carcinogen?
Short answer: Properly refined petrolatum is considered safe.
Here’s the concern: PAHs, or polycyclic aromatic hydrocarbons, which are potentially carcinogenic.
- In the EU, petrolatum must be adequately refined, and companies must provide full documentation to prove PAHs are removed.
- In the US, regulation is looser. If petrolatum is used in OTC drug products (like healing ointments), it must meet USP standards with strict PAH limits.
If used in cosmetics, however, there’s no mandatory testing unless a problem arises.
So is there risk?
Very low—if you’re buying reputable, tested products. But if you’re a clean beauty enthusiast or prefer EU-regulated brands, you might want to look for USP-grade or “white petrolatum” in the ingredient list.
Which Products Use Petrolatum?
Here are just a few common products containing petrolatum:
- Vaseline Original Healing Jelly
- Aquaphor Healing Ointment
- CeraVe Healing Ointment
- A+D Diaper Rash Cream
- Neosporin
- Vicks VapoRub
- ChapStick
- Penaten Cream
It’s also found in countless moisturizers, baby care products, and lip balms.
How Is Petrolatum Regulated?
In the United States:
- The FDA does not require pre-market approval of petrolatum in cosmetics.
- If used as an active ingredient (e.g. skin protectant), it must meet USP or NF standards.
In the European Union:
- Petrolatum must come from a non-carcinogenic source or be thoroughly tested.
- Brands must keep a Product Information File (PIF) and submit to inspections.
So yes—it’s regulated. But how tightly? That depends on where you live.
Where Else Is Petrolatum Found?
Petrolatum is surprisingly versatile. It’s used in:
- Fruit and vegetable wax coatings
- Industrial lubricants
- Veterinary digestive aids
- Eye ointments
- Paw balms for pets
- Sealants for lab equipment
Basically, it’s the Swiss Army knife of semi-solid hydrocarbons.
Is Petrolatum Sustainable?
Here’s where things get murky.
On one hand:
- It’s a byproduct, not the main product
- It uses leftovers from crude oil refining, which would otherwise be waste
On the other:
- It’s still derived from fossil fuels
- It’s not biodegradable, so it can linger in the environment
So while petrolatum may not be a sustainability superhero, it’s not the worst offender either. It all depends on how you define sustainable.
Are There Better Alternatives to Petrolatum?
Natural alternatives:
- Beeswax
- Shea butter
- Cocoa butter
- Lanolin
- Castor oil
- Candelilla wax
Synthetic alternatives:
- Dimethicone (a type of silicone)
- Hydrogenated polyisobutene
- Caprylic/capric triglycerides
- Polyethylene
All have their pros and cons—from texture to comedogenic rating to sustainability. Some work well, some… meh. But none quite match the occlusive power of petrolatum.
So… Should You Ditch Petrolatum?
That’s up to you.
Here’s what I do:
- I don’t panic if I see petrolatum in a product
- I stay informed
- I seek cleaner alternatives when possible
- I buy from trusted brands that use USP-grade petrolatum
Because as Carl Sagan once said:
“Absence of evidence is not evidence of absence.”
It’s all about balance. Knowledge is power, and fear doesn’t belong in your skincare routine.
Conclusion: Petrolatum Isn’t the Villain
- It’s effective, cheap, and generally safe
- It’s been used for over 150 years
- It’s found in dermatologist-recommended products
- It has some environmental drawbacks, but it’s a byproduct—not a primary pollutant
So if you love Vaseline, Aquaphor, or your diaper cream—go ahead and keep using it.
And if you prefer beeswax or shea butter? That’s fine too.
