Pine Wood Tar

INCI: Pinus Palustris Wood Tar

A traditional natural ingredient with soothing and cleansing properties, but its strong scent and potential for irritation mean it's best for occasional use in rinse-off products.

In plain English

Pine wood tar is a sticky, dark liquid made by heating pine wood in a low-oxygen environment (a process called destructive distillation). It has a strong, smoky, woodsy smell. In skincare, it's used in small amounts in soaps, shampoos, and ointments because it can help calm irritated skin and gently cleanse. Think of it as a natural, old-fashioned ingredient that's making a comeback for certain skin concerns, but it's not for everyone due to its potent aroma and potential to cause irritation or clog pores.

What it is

Pine wood tar is a natural byproduct of heating pine wood. It's a complex mixture of organic compounds including phenols, hydrocarbons, and resins. It has been used for centuries in traditional medicine and soap making for its soothing and cleansing properties.

How it works

In a cosmetic product, pine wood tar works primarily as a soothing and cleansing agent. The phenolic compounds in the tar are believed to help calm skin irritation and reduce the appearance of redness. Its resinous nature also helps it bind to dirt and excess oil, making it a gentle cleanser. However, these same compounds can be irritating to some skin types, especially at higher concentrations.

Pros

Traditional soothing properties

Pine wood tar has a long history of use in folk remedies for calming irritated skin, and many users report a noticeable soothing effect in soaps and ointments.

Effective natural cleanser

Its resinous nature helps it bind to dirt and excess oil, making it a gentle but effective cleanser in soaps and shampoos without stripping the skin.

Cons and cautions

Strong, lingering scent

The smoky, woodsy aroma is very potent and can linger on the skin and in the bathroom for hours, which may be unpleasant for many users.

Potential for irritation and clogged pores

The phenolic compounds can cause stinging or redness on sensitive skin, and the tar's heavy, resinous texture may clog pores for those prone to breakouts.

Best for

  • People with occasional dry, itchy patches looking for a traditional soothing ingredient
  • Those who enjoy natural, rustic-scented bath and body products

Use caution if

  • Individuals with sensitive or acne-prone skin
  • Anyone who dislikes strong, smoky smells

Usage tips

Start with a low concentration product (like a soap with less than 2% pine tar) to see how your skin reacts.
Use in rinse-off products like soap or shampoo rather than leave-on creams to minimize irritation risk.
Patch test on a small area of skin before full use, especially if you have sensitive skin.

Safety summary

Pine wood tar is generally considered safe for cosmetic use at low concentrations, but it can cause skin irritation and allergic reactions in some individuals. It is not recommended for sensitive or acne-prone skin. Always patch test before use.

Research notes

Research on pine wood tar is limited, but its traditional use and some studies suggest it has soothing and antimicrobial properties. Most evidence is anecdotal or from traditional medicine, not large-scale clinical trials.

Common label clues

Typical concentration
0.5% to 5% in rinse-off products; lower in leave-on products
Regulatory status
Approved for use in cosmetics in the US and EU, with no specific concentration restrictions, but formulators are advised to consider irritation potential.
Common uses
Soaps, Shampoos, Ointments, Bath products
Environmental note
Sourced from sustainably harvested pine wood, but the distillation process does produce some emissions. Look for brands that use responsibly sourced pine.

Good to know

  • Pine wood tar is different from pine oil or pine extract, which are much milder and have a different chemical profile.
  • The strong scent can be partially masked by other essential oils, but it's rarely completely covered.
  • It is often used in traditional 'pine tar soap' for its purported soothing properties.
