Ingredient review
Synthetic Petrolatum
INCI: Synthetic Petrolatum
Synthetic Petrolatum is a reliable, non-comedogenic occlusive that locks in moisture without the impurities of natural petroleum jelly.
In plain English
Synthetic Petrolatum is a man-made version of petroleum jelly. It works by forming a thin, breathable film on your skin that prevents water from evaporating, keeping your skin hydrated longer. Unlike natural petroleum jelly, it is purified in a lab, so it contains no potential contaminants like polycyclic aromatic hydrocarbons (PAHs). It feels smooth and greaseless, making it a popular choice for dry skin and lip care products.

Quick decision guide
Useful, but context matters
Synthetic Petrolatum is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Synthetic Petrolatum.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Synthetic Petrolatum is a synthetic mixture of hydrocarbons produced in a controlled laboratory process, designed to replicate the occlusive and emollient properties of natural petrolatum (petroleum jelly) without the impurities.
How it works
It sits on the surface of the skin and creates a physical barrier that slows down transepidermal water loss (TEWL), which is the natural loss of water from the skin. This helps maintain skin hydration and protects the skin barrier from environmental stressors.
Pros
Pure and consistent
Because it's made in a lab, Synthetic Petrolatum is free from the potential contaminants (like PAHs) that can be present in natural petroleum jelly, making it a cleaner option for sensitive skin.
Non-comedogenic
Unlike some heavy oils and butters, Synthetic Petrolatum has a low comedogenic rating, meaning it is unlikely to clog pores or cause breakouts, even for those with acne-prone skin.
Cons and cautions
Not a humectant
Synthetic Petrolatum only seals in existing moisture; it does not attract water to the skin. For best results, it should be applied over a water-based serum or moisturizer.
Can feel heavy on oily skin
While non-comedogenic, its occlusive nature can feel greasy or heavy on already oily skin types, potentially leading to a shiny appearance.
Best for
- People with dry or dehydrated skin
- Those who need a gentle, non-irritating barrier for sensitive skin
Use caution if
- Individuals with very oily or acne-prone skin may find it too heavy
Usage tips
Safety summary
Synthetic Petrolatum is considered safe for cosmetic use. It is non-irritating, non-comedogenic, and free from the impurities that can be present in natural petrolatum. No significant safety concerns have been reported in typical use concentrations.
Research notes
Research on Synthetic Petrolatum is limited compared to natural petrolatum, but existing studies confirm its efficacy as an occlusive agent. It is widely used in dermatological formulations for barrier repair and dry skin management.
Common label clues
- Typical concentration
- 1% to 20%
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and the European Commission. It is considered safe when used as intended.
- Common uses
- Moisturizers, Lip balms, Barrier creams, Ointments
- Environmental note
- As a synthetic hydrocarbon, it is not biodegradable and is derived from non-renewable resources, though its production can be more controlled than mining natural petroleum.
Good to know
- Synthetic Petrolatum is often used in 'clean beauty' formulations as a purified alternative to natural petrolatum.
- It is vegan and cruelty-free, as it does not require animal-derived ingredients.
