Petroleum, along with many impurities, then is extracted and released mineral oil. Mineral oil has a high-viscosity, low-cost, and hypoallergenic properties. Majority of vegetable oils come under edible oil; however not all.
There are few vegetable oils and all petroleum oils which are not suitable for eating and have industrial demand. Such oils are grouped under the umbrella of non-edible oils. Even animal fats also come under this group. Various differences between edible oil and non-edible oil are given below in table format.
Sources: Edible oils are directly extracted from oilseed grains, nuts and tree fruits. Thus their sources are predominantly organic; for example seeds of groundnut, soybean, sunflower, rapeseed, linseed, safflower, peanut, etc.
Oil extracted from tree fruits or seeds like palm oil, coconut oil, olive oil, etc. All vegetable oils are not edible; some vegetable oils have low demand as food source. There are more than 50 crops whose oil is primarily used for industrial purposes, some popular examples are rubber, neem, tobacco, castor, drumstick, almond, avocado, tomato, bean, date, rice, milkweed, sal, salmon, kusum, jojoba, etc. Apart from these non-edible vegetable oils, petroleum based oils and animal fat are predominantly used for non-edible purposes.
So non-edible oils consist of non-edible vegetable oils, petroleum oils, and animal fats and therefore, it can be organic or inorganic. However, there exist no clear boundary between culinary use and industrial use, so certain oils can be used for both purposes based on market demand and production. Applications: Edible oils are consumed, directly or indirectly, as food ingredients. They can also be consumed directly like flavouring without any culinary processing; however, in limited amount.
Non-edible oils are not used as food intake, rather they are utilized in various forms for several industrial applications. Few major consumers of such oils are transport industries, candle, soap, synthetic detergent, resin, ink, wax, dye, paint and varnish factories. Non-edible vegetable oils, which are also known as second generation feedstock, can be used for sustainable production of biodiesel and thus have emerged as promising substitute for rapidly depleting petroleum oil reserves.
Apart from fuel, they can also be used for the production of lubricant, coolant, engine oil, grease, etc. Some of them also have pesticidal, medicinal and cosmetic usages. Nutritional value: Edible oils must be rich in nutrition; ideally such oils should be digestible, rich in caloric value and free from unsaturated fat. Although it can be used to relieve occasional constipation, castor oil is not recommended as a treatment for long-term issues.
Summary Castor oil can be used as a natural remedy for occasional constipation. However, it can cause side effects like cramping and diarrhea and should not be used to treat chronic constipation. Castor oil is rich in ricinoleic acid, a monounsaturated fatty acid. Humectants retain moisture by preventing water loss through the outer layer of the skin 5. Castor oil is often used in cosmetics to promote hydration and often added to products like lotions, makeup and cleansers.
You can also use this rich oil on its own as a natural alternative to store-bought moisturizers and lotions. Many popular moisturizing products found in stores contain potentially harmful ingredients like preservatives, perfumes and dyes, which could irritate the skin and harm overall health 5.

Castor oil stimulates tissue growth so that a barrier can be formed between the wound and the environment, decreasing the risk of infection. It also reduces dryness and cornification, the buildup of dead skin cells that can delay wound healing 8. Studies have found that ointments containing castor oil may be especially helpful in healing pressure ulcers, a type wound that develops from prolonged pressure on the skin.
One study looked at the wound-healing effects of an ointment containing castor oil in nursing home residents with pressure ulcers. Those whose wounds were treated with castor oil experienced higher healing rates and shorter healing times than those treated with other methods 9. Summary Castor oil helps heal wounds by stimulating the growth of new tissue, reducing dryness and preventing the buildup of dead skin cells. Ricinoleic acid, the main fatty acid found in castor oil, has impressive anti-inflammatory properties.
Studies have shown that when castor oil is applied topically, it reduces inflammation and relieves pain. The pain-reducing and anti-inflammatory qualities of castor oil may be particularly helpful to those with an inflammatory disease such as rheumatoid arthritis or psoriasis. Animal and test-tube studies have found that ricinoleic acid reduces pain and swelling One study demonstrated that treatment with a gel containing ricinoleic acid led to a significant reduction in pain and inflammation when applied to the skin, compared to other treatment methods A test-tube component of the same study showed that ricinoleic acid helped reduce inflammation caused by human rheumatoid arthritis cells more than another treatment.
Although these results are promising, more human studies are needed to determine the effects of castor oil on inflammatory conditions. Summary Castor oil is high in ricinoleic acid, a fatty acid that has been shown to help reduce pain and inflammation in test-tube and animal studies.
