When you’re deciding on a finish for butcher blocks and cutting boards, mineral oil may end up on your list of potential candidates. Using even food-grade mineral oil, however, most often proves a big mistake for surfaces that see food contact for both safety and durability reasons. The potential to clog pores makes mineral oil bad for your skin, while its lack of water resistance makes it a poor choice for your wood. Not to mention questionable origin. Fortunately, the Real Milk Paint Co. has alternatives to the latter problem with high-quality finishes that negate the need to use mineral oils in your woodworking and restoration projects.

Mineral Oils and Their Many Uses

Pure tung oil for wood finishingTo understand why mineral oil isn’t a good choice for creating a protective barrier on wood projects, you must first know its origins. Chemically similar to petroleum jelly minerals oils — even the highly refined ones — are still derived from petroleum “(petroleum distillate),” which automatically gives them a bad rap from those concerned with sustainability and the environment. Despite this and the fact it may clog pores, mineral oil is used in cosmetics, skincare products, baby oil and many products for acne-prone skin due to its nonreactive, odorless and tasteless nature. Other common products that utilize mineral oil include:

  • Packaging materials
  • Cold creams
  • Liquid makeup removers
  • Body creams and body oil
  • Hair care products
  • Cleaners and air fresheners
  • Machine and engine oils
  • Agricultural products
  • Aviation industries
  • Animal foods
  • Cutting Board Finishes
  • Industrial chemicals

Why Not To Use Mineral Oil

Aside from the fact that petroleum-based products are bad for the environment, mineral oil has other downsides that may affect how you feel and look and inhibit the durability and care of your home décor. Consider the following reasons and strong evidence when you want to understand why we don’t recommend mineral oil for application on dry skin or various uses around the home.

Human Health Concerns With Mineral Oils

Though many mineral oils are highly processed to remove impurities, especially when used in products to keep skin moisturized, moderately refined mineral oils have a carcinogen classification. This moisturizing ingredient is often used in lubricants for machinery, and the type of mineral oil used in industry has the downside of potentially leading to complications such as skin cancer with frequent contact. Generally speaking, food- and cosmetic-grade mineral oil for dry skin usually boasts top-notch quality levels and usually has some other active ingredient. Issues with allergies and toxicity may still be an issue, however, even when you just use mineral oils to keep your skin moisturized, since it’s so closely related to petroleum jelly. For the bottom line, mineral oil is something to stay away from if you’re the least bit unsure about its provenance.

Issues With Cosmetic Products Containing Mineral Oils

Typically used as a filler ingredient in over-the-counter beauty products for those with dry skin, mineral oil was once praised for its hydrating properties. Other products like hyaluronic acid, however, provide a safer protective layer for skin that locks moisture in and staves off premature aging without the use of harsh occlusive agents. This means, however, that you may encounter a skincare formulation that combines mineral oil with essential oils and other moisturizing ingredients (and other potentially pore-clogging ingredients!) like vitamin E, shea butter, cocoa butter, coconut oil or jojoba oil.

Though touted as a noncomedogenic way to protect the skin barrier, the mineral oil in these formulations may lead to cosmetic issues such as clogged pores on certain skin types like oily skin, acne-prone skin or sensitive skin. Others who apply mineral oil to their skin may incur an unexpected skin reaction or rash, sometimes requiring a visit to a cosmetic dermatology professional. This is because the occlusive ingredient in mineral oil clogs pores by locking the skin barrier, preventing natural perspiration. Additionally, avoid beauty products like sun care lotions containing mineral oils on any of these skin types, as they may lock in sunburns and cause permanent scarring.

Wood Finish Considerations With Mineral Oils

Beyond potentially leading to health concerns and clogging pores, mineral oil isn’t very kind to your wood furnishings over time. Unhealthy impurities and concerns that applications of mineral oil cause cancer make this finish wholly unsuitable for food contact surfaces like butcher blocks, cutting boards, charcuterie boards and wood countertops, but other factors make mineral oil bad for other surfaces as well.

While mineral oils might clog pores when used in skincare products, they don’t waterproof surfaces, so if you finish a table with these formulations, it may retain water rings from glasses. Counterintuitively, surfaces finished with mineral oils undergo water loss since there’s no real barrier effect on wood. Other reasons not to use mineral oil on wood include lack of durability, inability to protect against scratches and need for frequent reapplication.
