What is petroleum jelly?

Petroleum jelly is a chemical compound, a semi-solid mixture of hydrocarbons refined from petroleum, used for generations as a simple occlusive moisturizer. It is sold and known under several names: the brand name Vaseline, the technical term petrolatum, and the older label soft paraffin all describe the same material. It sits on the skin and slows water loss, which is why it is a common eczema and diaper-area staple. A comprehensive review of petroleum jelly describes how its occlusive properties make it an effective, low-cost moisturizer, while clearing up several myths about it. Petrolatum works, but it is a petroleum derivative with no botanicals. That is the difference many families weigh when choosing a daily balm.

​
The properties behind petroleum jelly benefits

A few physical traits explain the well-known petroleum jelly benefits. Its melting point is fairly high, roughly in the 36 to 60 degree Celsius range, so it stays put as a soft solid at skin temperature rather than running off. Its viscosity is that of a semi-solid at room temperature, thick and greasy, which is exactly what lets it form a lasting occlusive seal. And it is a blend of hydrocarbons of moderate molecular weight, on the order of 300 to 700 grams per mole, large enough to sit on the surface rather than soak in. Together those properties, a high melting point, a semi-solid viscosity, and a moderate molecular weight, are why a thin film locks moisture in so reliably. Proper petroleum jelly application is simply a thin layer over clean, slightly damp skin.

​
Plant oils as an alternative occlusive

Emollient plant oils and butters can seal the skin much as petrolatum does, while adding fatty acids and soothing compounds of their own. Research on preventing infant eczema has compared moisturizer types head to head; a randomized trial in high-risk neonates tested different moisturizer regimens, including petroleum jelly, for their effect on atopic dermatitis. Era Organics chose a plant-based route. Its Baby Eczema Superbalm seals with oils like coconut oil and beeswax instead of petrolatum, and it is mineral-oil-free by design. Those same emollient plant oils carry fatty acids that support the barrier.

How petroleum jelly compares to other formats

Petroleum jelly sits at one end of a spectrum of moisturizers. At the other end are a water-based moisturizer, a light lotion or gel that is mostly water and absorbs quickly, and the oil-free formula, a product built to skip greasy occlusives entirely. Those lighter formats feel cleaner and suit oily or acne-prone skin, but they do far less to lock moisture into a dry, cracked barrier. Petroleum jelly is the opposite kind of tool: heavy, greasy, and purely occlusive, doing one job very well. A plant-oil balm lands between them, sealing like an occlusive while adding the botanicals a water-based moisturizer or oil-free formula leaves out. Neither extreme is wrong; they are matched to different skin and different needs.

​
How Superbalm compares

Petroleum jelly is a pure occlusive: it locks moisture in but does nothing else. Superbalm aims to do more, pairing an occlusive plant-oil base with gluten free oats and soothing botanicals like chamomile and calendula. For a family that prefers to avoid petroleum products on a baby, it is a plant-based option. Superbalm is labeled as an OTC ointment that temporarily protects and helps relieve itch and irritation from eczema, and it is fragrance-free. It sits alongside other barrier options like ceramide creams in the broader eczema toolkit. For the full formula and uses, see the Baby Eczema Superbalm reference.

Frequently asked questions about petroleum jelly

​
Is petroleum jelly bad for eczema?

Petroleum jelly is a safe, effective occlusive moisturizer that many dermatologists recommend. Some families simply prefer a plant-based balm; Superbalm offers that while adding gluten free oats and botanicals like chamomile and calendula.

​
How do you apply petroleum jelly?

The usual method is to apply petroleum jelly in a thin layer over clean, slightly damp skin so it traps the moisture underneath. A little goes a long way, since its job is to sit on the surface and seal.

​
Is Superbalm petroleum-free?

Yes. Superbalm contains no petrolatum or mineral oil and seals the skin with plant oils and beeswax instead. It is also fragrance-free.

​
Which is better for a baby, petroleum jelly or Superbalm?

Both help protect the barrier; the choice comes down to preference. Petroleum jelly is a bare-bones occlusive, while Superbalm adds oats and soothing plants in a base of plant oils and beeswax. Patch test any new product and check with your pediatrician.
