Mineral oils are petroleum-based saturated fats primarily used in skin care products for their hydrophobic properties that keep water from passing through the mineral oil.
They are extremely effective in preventing trans-epidermal water loss (TEWL), so are often found in occlusive moisturizers meant for use on the face.
They are derived from petroleum, like petrolatum and paraffin.
They are called mineral oils and not "petroleum oils" because medical terminology was not always standardized; the name mineral oil was likely born as a marketing tool.
Because of vagueness of the phrase "mineral oils," many other names are used to describe individual mineral oil products or the group of ingredients as a whole.
Some common ways to see mineral oil products referred are (1):
Heavy mineral oil
Light mineral oil
Liquid paraffin
Liquid petrolatum
Mineral oil mist
Paraffin oil
Petrolatum liquid
Petrolatum oil
Petroleum jelly
White mineral oil
White oil
Is mineral oil used in skin care?
Mineral oils have been used for centuries in skin care because they are cheap, effective, colorless, odorless, and easy to formulate in skin care products.
Petroleum- based ingredients, such as petrolatum and paraffin, are considered by some to be too inelegant for use skin care products because they are thick and greasy to the touch.
If your skin is acne-prone, mineral oils might not be recommended for your face, because although mineral oil is not comedogenic, it can hold sebum, dirt, silicones, and sunscreen in the hair follicles leading to comedones.
You can use mineral oil on your face if you need a good, affordable, hydrating moisturizing ingredient, but there are many other natural oil options.
One study found that an emulsion containing mineral oil prevented evaporative water loss more effectively than multiple common linoleic acid based emulsions. (19)
Which are the most common mineral oils?
The two most common mineral oils used in skin care are
Paraffin
Petrolatum
Dangers of mineral oil
Since mineral oils are derived from petroleum, many people are concerned it poses risks in skin care, particularly as a carcinogen; this is just a myth. (23)
The only universal drawback of using mineral oil products is that petroleum is not a sustainable resource and has a large carbon footprint.
Cosmetic grade mineral oils are absolutely not comedogenic. However, their occlusive properties can hold comedogenic substances like sebum on the face leading to clogged pores.
Certain industrial grade mineral oils are listed as comedogenic ingredients to fulfill regulation requirements, but are not actually used in skin care products.
A 2005 study suggests that even though industrial grade mineral oil may be comedogenic, cosmetic grade mineral oils are positively non-comedogenic (18).
Do mineral oils cause cancer?
Mineral oils do not cause cancer on the skin, not even on thin, sensitive skin areas like the lips.
No definitive links with cancer have been found in uses of cosmetic or food-grade mineral oils.
One study shows that even when mineral oils were consumed orally at 2000 times the accepted daily levels, rats were no more or less likely to develop cancerous tumors than a control group. (3)
With all that being said, it is somewhat possible mineral oil based products may concentrate beams of light, the same way a mirror might, onto the skin beneath.
Hypothetically, this could expose skin to more potent UV rays than normal, which could potentially lead to sun damage and skin cancer, however no studies support this concern.
The bottom line on mineral oil and lip cancer: If you choose to wear a mineral oil containing lip balm in the sun, apply a lip sunscreen on top to protect your lips.
Are mineral oils safe for use in skin care?
Cosmetic grade mineral oils are completely safe for use in skin care.
The EWG rating for petrolatum, one of the two most common mineral oils in skin care, is listed as "1-4, depending on usage."
That rating means it is considered completely safe in some forms, and fairly unsafe in other forms. The difference is whether it is a cosmetic or industrial grade mineral oil.
Only use skin care products with cosmetic grade mineral oil. Stick with reputable skin care brands!
Coconut oil vs mineral oil
Both coconut oil and mineral oil can be comedogenic or not depending on how they processed.
Some studies have suggested that mineral oils are terrible for protecting the hair and skin from UV damage, they can intensify the suns rays which can result in worse damage (like a mirror).
Coconut oil reduced loss of proteins in hair much more significantly than mineral oil, which hardly helped with protein loss at all.
Coconut oil has high concentrations of lauric fatty acids, which bond easily with and hydrate hair proteins.
Mineral oil is a saturated fat and does not easily bond with proteins.
When considering hair care products, keep in mind the differences between mineral and coconut oils. You may not need to hydrate your hair, which means in some cases coconut oil might not be a better choice than mineral oils. What is best for you depends on your personal hair care concerns.
