Ingredient review
Naftalan Oil Extract
INCI: Naftalan Oil Extract
Naftalan Oil Extract is a traditional soothing oil with anti-inflammatory potential, but it is a crude oil derivative with limited modern safety data and a strong odor.
In plain English
Naftalan Oil Extract is a thick, dark oil that comes from a special type of crude oil found only in Croatia. It has been used for decades in balneotherapy (bath treatments) to help calm irritated or inflamed skin conditions like eczema and psoriasis. In skincare, it works as an emollient, meaning it softens and smooths the skin, and is thought to have anti-inflammatory effects. However, because it is a petroleum-based ingredient, it has a strong, distinctive smell and may be comedogenic (pore-clogging) for some people. Modern safety data is limited, so it is less common in mainstream products.

What it is
Naftalan Oil is a naturally occurring, thick, dark oil extracted from a specific type of crude oil found in the Naftalan region of Croatia. It is a complex mixture of hydrocarbons and other organic compounds, and has been used historically in therapeutic baths and topical treatments for skin conditions.
How it works
In a cosmetic product, Naftalan Oil acts primarily as an emollient, forming a protective layer on the skin that helps reduce water loss and soften the skin. It is also believed to have anti-inflammatory and soothing properties, possibly by interacting with skin cells to calm irritation, though the exact mechanism is not fully understood.
Pros
Traditional soothing ingredient
Has been used for decades in balneotherapy to calm irritated skin conditions like eczema, offering a time-tested option for those seeking alternative remedies.
Effective emollient
As a thick oil, it provides strong moisturization and helps repair the skin barrier by reducing water loss, making it useful for very dry or compromised skin.
Cons and cautions
Strong, unpleasant odor
The oil has a distinct, heavy petroleum-like smell that can be off-putting and may require strong fragrances to mask, which can irritate sensitive skin.
Limited modern safety data
Despite its traditional use, there are few recent peer-reviewed studies on its safety and efficacy in modern cosmetic formulations, making it a less reliable choice.
Best for
- People with very dry, rough, or flaky skin looking for a heavy emollient
- Those interested in traditional or niche skincare ingredients with a history of use for inflammatory skin conditions
Use caution if
- People with oily or acne-prone skin due to potential pore-clogging
- Those sensitive to strong odors or who prefer fragrance-free products
Usage tips
Safety summary
Naftalan Oil Extract has a long history of traditional use in bath therapies for skin conditions, but modern cosmetic safety data is limited. It is generally considered safe for topical use in low concentrations, but it may cause irritation or clog pores in some individuals. The strong odor and petroleum origin are practical drawbacks.
Research notes
Research on Naftalan Oil is sparse and mostly historical or focused on balneotherapy. A few older studies suggest anti-inflammatory and antimicrobial properties, but there are no recent large-scale clinical trials supporting its use in modern skincare. The evidence level is considered emerging.
Common label clues
- Typical concentration
- Typically 1-10% in leave-on products
- Regulatory status
- Naftalan Oil Extract is not specifically regulated by the FDA as a cosmetic ingredient, but it must meet general safety and labeling requirements for cosmetics. In the EU, it is listed in the CosIng database as a skin conditioning agent, but its use is not restricted.
- Common uses
- Soothing creams, Bath oils, Balms for dry or irritated skin
- Environmental note
- As a crude oil derivative, Naftalan Oil is a non-renewable resource. Its extraction and processing have environmental impacts similar to other petroleum products, which may be a concern for eco-conscious consumers.
Good to know
- Naftalan Oil is not the same as mineral oil or petrolatum; it is a specific crude oil from a single geographic region.
- The oil is often used in heated bath treatments in spas, but in skincare it is typically found in creams and balms.
- Due to its strong odor, it is rarely used in modern, fragrance-conscious formulations.
