Safflower oil is a vegetable oil derived from the seeds of the safflower plant, a member of the sunflower family1.

The flower thrives in arid climates2, such as those found in South Asia, China, India, Iran, and Egypt, and has long been used3 for medicinal purposes, including the treatment of menstrual pain and dysfunction, postpartum abdominal pain, and joint pain. Safflower oil in particular has been used2 in some areas of Asia and Africa to ease fevers, as well as in China, Japan, and Korea to improve4 skin and hair health.

Outside of medicinal purposes, safflower oil is also used as a cooking oil, thanks to its high smoke point of 450 degrees Fahrenheit, says Michelle Shapiro, R.D., a functional registered dietitian.

“Safflower oil, specifically high-oleic safflower oil, has a higher smoke point than other commonly used vegetable oils and is used for frying, sauteing, and other methods that may require high heat,” she notes. “It can be heated to high temperatures without breaking down and releasing harmful compounds.”

Since safflower oil is also nearly flavorless, it’s commonly used in processed foods, including baked goods, chips, popcorn, margarine, salad dressings, mayonnaise, and snack bars, she says.

To extract safflower oil from the plant’s seeds, processors may use chemical solvents (such as hexane) or supercritical carbon dioxide5 (aka high-pressure CO2), says Shapiro.

Mechanical extraction methods are also used: In the cold-pressing process, safflower seeds are crushed and pressed, then the oil is extracted at a low temperature to maintain its nutritional value, she notes. The expeller-pressing process is similar, but the oil is extracted at a higher temperature, she says.

There is also some safflower oil that is extracted using both chemical and mechanical processes.

After extraction, safflower oil is often refined to remove free fatty acids that can impact taste, waxes, and other natural compounds; bleached to reduce colored pigments; and deodorized to fully eliminate those free fatty acids and odors, research shows6. “This is done to create a consistent, shelf-stable, neutral-flavor product,” says Shapiro.

Summary

Safflower oil is derived from the safflower plant, a member of the sunflower family. It has a history of medicinal uses in the Middle East, Asia and Africa, and has been used to treat joint pain, menstrual dysfunction, and more. Now frequently used in processed foods, safflower oil has a high smoke point and neutral flavor profile.

• Saturated fat: 0.84 grams
• Monounsaturated fat: 1.96 grams
• Polyunsaturated fat: 10.1 grams
• Vitamin E: 4.64 milligrams

Though it depends on the batch, safflower oil usually contains low levels of saturated fat. Saturated fat can increase levels of low-density lipoprotein (aka LDL, or “bad”) cholesterol and raise the risk for heart disease and stroke8 when consumed in excess. The oil also contains high amounts of unsaturated fats, which can reduce the risk of cardiovascular disease9 when consumed in place of saturated fat.

On average, safflower oil contains about 16 to 20% monounsaturated fatty acids (in the form of oleic acid) and 71 to 75% polyunsaturated fatty acids (in the form of linoleic acid), according to research10 published in Metabolites. However, the exact ratio of monounsaturated to polyunsaturated fatty acids can vary, depending on the specific type of oil, says Shapiro. 

Polyunsaturated fats can be divided into two categories: omega-3 fatty acids and omega-6 fatty acids, says Shapiro. “[Both] omega-3 and omega-6 fatty acids must be consumed in the diet, but it is important that they are consumed in a balanced ratio,” she explains. “In safflower oil, there are negligible amounts of anti-inflammatory omega-3 fats, [and] most of the polyunsaturated fatty acids in safflower oil are omega-6 fats.”

When eaten in excess and without a balance of omega-3 fatty acids, omega-6 fatty acids can increase pro-inflammatory markers in the body11, she adds.

Summary

Low in saturated fat, safflower oil contains polyunsaturated fatty acids with the majority being omega-6s. It is important to consider how much and which types of polyunsaturated fats you are consuming, as the standard diet is high in omega-6s and there should be a better balance of anti-inflammatory omega-3s in our food.

• High-oleic safflower oil: This type of safflower oil is made from seeds that boast a higher percentage of oleic acid, a monounsaturated fatty acid, says Shapiro. In turn, the oil will typically have a higher proportion of monounsaturated fats than polyunsaturated fats. Specifically, it offers 10.2 grams of monounsaturated fats and 1.74 grams of polyunsaturated fats per tablespoon, according to the USDA12. “High-oleic safflower oil has a longer shelf life and a higher smoke point of 440-520 degrees Fahrenheit, making it suitable for high-temperature cooking and frying,” she notes.
• High-linoleic safflower oil: Safflower oil labeled as “high linoleic” is made from seeds rich in linoleic acid, a type of polyunsaturated fatty acid, says Shapiro. This variety’s unsaturated fatty acid profile is nearly the opposite of high-oleic safflower oil: One tablespoon of high-linoleic safflower oil contains 1.96 grams of monounsaturated fats and 10.1 grams of polyunsaturated fat, according to the USDA7. Though it can be used for cooking, it’s also found in cosmetic products, notes Shapiro.
• Expeller-pressed safflower oil: This safflower oil is extracted via mechanical methods that don’t involve the use of solvents or chemicals, says Shapiro. “The oil has a mild-nutty flavor and a lower smoke point of 225 degrees Fahrenheit compared to refined versions,” she says. “Expeller-pressed safflower oil is often used in salad dressings, marinades, and other cold dishes.”

It may improve heart health in moderation. 

Thanks to its low saturated fat and high unsaturated fat contents, safflower oil may improve heart health when consumed in moderation. In fact, reducing saturated fat intake and consuming polyunsaturated vegetable oil instead has been found to reduce the risk of cardiovascular disease by roughly 30%, research shows13. 

What’s more, “monounsaturated fatty acids can help reduce LDL cholesterol levels in the blood, improve insulin sensitivity, and reduce inflammation in the body,” says Shapiro.

Research backs up this potential benefit of safflower oil, too. In a 2022 study14 of 67 individuals with metabolic syndrome (a combination of conditions that raise the risk of coronary heart disease, diabetes, or stroke), the participants who consumed 8 grams of safflower oil daily for 12 weeks—without changing their diet or physical activity—showed a significant reduction in systolic blood pressure and insulin resistance.

It’s rich in vitamin E.

It may support healthy skin.

With its moisturizing4 and anti-inflammatory16 properties, safflower oil can be a beneficial addition to skincare routines according to early research, says Marisa Garshick, M.D., F.A.A.D., a board-certified dermatologist based in New York City. The oil’s linoleic acid may help treat breakouts, making it a particularly useful ingredient for individuals with acne-prone skin, she notes. 

In addition, the oil is rich in antioxidants that can support wound healing, says Garshick. In a 2020 study3, researchers found that safflower oil’s antioxidants demonstrated both antibacterial and antifungal effects, making it a suitable option to manage skin wounds and potential infections.

To top it off, safflower oil may prevent UVB ray-induced photoaging and, in turn, the development of wrinkles, according to 2020 research4.

It’s high in omega-6 fatty acids.

The omega-6 fatty acids found in safflower oil aren’t inherently harmful to health. In fact, they serve as17 important structural components of cell membranes and provide energy. But it’s important to keep your consumption of omega-6s balanced with omega-3 fatty acids.

“High omega-6 fatty acid intake can increase pro-inflammatory markers in the body when consumed in excess,” says Shapiro. And most people eating a typical Western diet are consuming too many foods rich in pro-inflammatory omega-6 fats, and not enough sources of anti-inflammatory omega-3 fats, she adds.

Over time, consuming excess amounts of omega-6 fatty acids while skimping on omega-3s may contribute to the development18 of chronic diseases, such as cardiovascular disease and cancer, says Shapiro. 

2.

It contains saturated fat. 

Although safflower oil is relatively low in saturated fat compared to other cooking oils, it could be potentially harmful when consumed in excess.

Reminder: Consuming too much saturated fat may lead to a build-up of cholesterol in the arteries, decreasing blood flow19 to the heart, brain, and kidneys, and can raise LDL cholesterol levels, increasing the risk of heart disease and stroke, according to the National Library of Medicine.

To prevent these health concerns, the USDA recommends limiting saturated fat intake to 10% of calories per day, or about 22 grams for a person following a 2,000-calorie diet. 

3.

It generally requires chemical herbicides to grow.

In the United States, safflower plants struggle to compete with weeds, particularly when they’re in the rosette stage and before the stems elongate. Interference from weeds throughout the growing season can reduce safflower grain yields by 93%, so a weed control program, such as the use of herbicides, is necessary.

Some herbicides approved for use with safflower—including glyphosate—may harm the environment.

A recent assessment by the U.S. Environmental Protection Agency20 suggests that glyphosate poses potential ecological risks to terrestrial and aquatic plants, mammals, and birds, and the risk for bees is currently uncertain. Glyphosate tends to accumulate in topsoil21 and, due to surface runoff, soil drift, and other natural processes, may enter groundwater and surface water.

For these reasons, you should opt for organic safflower oil in your food and beauty products when possible.

Safflower oil contains hearty-healthy unsaturated fatty acids and antioxidants that support the immune system and fend off harmful free radicals. High-linoleic safflower oil, in particular, is rich in plant-based monounsaturated fats that may lower the risk22 of coronary heart disease when eaten in place of saturated fats. Safflower oil can also be a useful addition to your skincare routine.

However, the oil does contain high levels of omega-6 fatty acids. Since the standard American diet already includes high amounts of the polyunsaturated fatty acid, you may be best off choosing an oil that’s rich in monounsaturated fatty acids and boasts slightly higher levels of omega-3s, such as olive oil or avocado oil. Highly processed foods that contain safflower oil, like chips or sugary dressings, are also best avoided.

Summary

While safflower oil is a solid pick for skincare, its high omega-6-to-omega-3 ratio means it’s not the healthiest choice for cooking. Opt for olive oil or avocado oil instead when you can.

A tablespoon of this fruit-derived oil offers24 14 grams of fat—just like safflower oil—and is rich in monounsaturated fat (9.88 grams) and low in polyunsaturated fat (1.89 grams). Avocado oil does contain a bit more saturated fat (1.62 grams) than safflower oil.

“Avocado oil is unrefined and has a higher smoke point [520°F] compared to olive oil, making it more suitable for cooking at higher temperatures,” says Shapiro. In turn, avocado oil is a better option for frying while boosting monounsaturated fat intake.

Is safflower oil better than olive oil? Olive oil contains25 14 grams of fat per tablespoon, most of which is monounsaturated fat (9.58 grams) and a little polyunsaturated fat (1.33 grams). Still, olive oil boasts double the amount of saturated fat (2.17 grams) as safflower oil.

The smoke point ranges from 350-470 degrees Fahrenheit, depending on the exact variety. “Not only is [extra-virgin olive oil] the ideal choice at lower cooking temperatures, research shows that it is also more stable at higher temperatures than other common cooking oils,” says Shapiro. Thanks to those properties, olive oil tends to be more versatile than safflower oil, and it offers more monounsaturated fats than its counterpart.

Summary

Safflower oil or products that contain safflower oil can be moisturizing and soothing when applied to skin (especially when combined with other antioxidant-rich ingredients like vitamin E or C). The oil is suitable for most skin types, but you’ll want to apply a test patch if you’ve never used it topically before.

With its unsaturated fat content and antioxidant properties, safflower oil is okay to consume in moderation, particularly when cooking at high temperatures. Plus, the cooking oil may keep your skin healthy and nourished when applied topically.

However, safflower oil does contain some LDL cholesterol-raising saturated fat and boasts a high ratio of omega-6 to omega-3 fatty acids, which may promote inflammation when consumed in excess. The herbicides used in safflower cultivation may also have environmental impacts. 

Ultimately, you’re better off using other more nutritious oils, such as olive oil and avocado oils, for everyday cooking.
