How Castor Oil is Made: Cold-Pressed vs Refined

Do you know why one castor oil costs more than another? Are you confused about which type of castor oil to buy for your needs? The production methods make all the difference in the final product created.

Castor oil is extracted from castor beans (Ricinus communis) and has many uses - from skin care to industry work. People have used this special oil for hundreds of years. With over a decade of experience in the field, Modi Oil Mill is excited to bring you a simple breakdown of these two types, showing their key differences.

Cold-Pressed Castor Oil

Cold-pressed castor oil is the most natural and purest form you can get. This method preserves maximum nutrients and therapeutic properties. Let’s check out how cold pressing keeps the oil pure and natural-

• Process: We crush castor seeds using heavy machines without adding heat. First, we clean the seeds and remove the outer shell. Then we press them using hydraulic or screw presses that squeeze out the oil. This gentle way keeps all the natural goodness in the castor oil.
• Temperature: The temperature stays below 60°C during the whole process. This low heat protects the heat-sensitive parts of the oil. Keeping it cool means preventing the breakdown of beneficial fatty acids and vitamins, keeping all its natural healing powers.
• Characteristics: Cold-pressed castor oil has a golden yellow colour and smells nutty. It's thicker than other oils and has more healing acids inside. The oil keeps all its natural vitamins and good fats that help your skin and hair stay healthy.
• Ricin: The pressing process removes most of the poison called ricin from castor beans. Some tiny amounts might stay, so we test everything to make sure it's safe. Professional manufacturers like us make sure that castor oil cold-pressed, is completely safe to use.
• Appearance: The oil looks pale yellow to golden with a slightly cloudy and thick feel because of natural particles inside. It smells mild and nutty, which shows it hasn't been processed much.

Refined Castor Oil

Refined castor oil goes through extra cleaning steps to eliminate colour, smell, and dirt. This makes a cleaner product that lasts longer on shelves. While it loses some natural benefits, refined castor oil works better for many business uses.

• Process: We clean crude castor oil using special chemicals and heat. Chemical solvents and alkalis are used in the process to remove acids, colours, and other unwanted substances. Each step makes the oil cleaner and more standard.
• Heat: We use high heat between 200-250°C during cleaning stages. Steam at high temperatures removes smells and unwanted parts.
• Characteristics: Refined castor oil has no colour or is very light yellow with almost no smell. It's thinner than cold-pressed and flows easily. It has improved oxidative stability and longer shelf life due to the removal of pro-oxidant compounds.
• Ricin: The cleaning process removes all toxins through heat and chemical cleaning. Many cleaning steps make sure refined castor oil is 100% safe for all uses. This complete cleaning makes it perfect for pharmaceutical and beauty products.
• Yield: Refining gets more oil from castor beans than cold-pressing does. Using chemicals and heat helps get every drop of oil from the beans.

Refined Castor Oil: Process & Applications

Refining Process of Castor Oil at Modi Oil Mill

• Degumming: We treat raw castor oil with acid and water to remove gums that make the oil cloudy and reduce its shelf life.
• Neutralization: We use a special soap solution to remove acids, then wash away all soap and extra chemicals from the oil.
• Belaching: We use special clay and carbon to take out colours and dirt under controlled heat and vacuum.
• Deodorization: We use steam under high heat and vacuum to remove all smells and remaining acids from the oil.
• Quality Testing: Every batch is carefully checked for acid levels, water content, colour, and purity to make sure it meets standards.

Benefits and Industrial Uses of Refined Castor Oil

• Beauty Products: Used in lipsticks, soaps, and creams for consistent quality and no smell.
• Medicine: Used in pills and medical creams for purity and safety.
• Machine Oil: Works well in hot machines and hydraulic systems.
• Paints: Helps paint flow better and dry properly.
• Cloth Making: Used in fabric finishing and dyeing for stability.

Cold-Pressed vs Refined Castor Oil: Key Differences

• Extraction Process: Cold-pressed castor oil uses machines to squeeze oil without heat, keeping all natural components and original nutrients. Refined castor oil uses chemicals and heat that clean out dirt but also remove some helpful parts.
• Nutritional Value: Castor oil cold pressed keeps more vitamin E, antioxidants, and natural fats that help skin and hair health. Refined castor oil has less nutrition because of processing but stays good longer and works the same every time.
• Colour, Odour, and Texture:Cold-pressed oil is golden yellow with nutty smell and thick feel that many people like better. Refined castor oil looks almost clear with very little smell and flows easily because of processing.
• Common Uses in Personal Care & Industry:Cold-pressed castor oil works best for natural skin care, hair treatments, and healing uses where keeping nutrients matters most. Refined castor oil is better for industrial applications, pharmaceutical manufacturing, and beauty products where being the same quality and longer-shelf life is needed.

Which Oil Should You Choose?

• For Beauty & Health: For natural skin care, hair care, and healing uses where you want maximum nutrients and natural benefits, cold-pressed castor oil is the best choice. It perfect for people who want organic, barely processed products.
• For Industrial Use: Refined castor oil is the better choice for industrial needs. It offers consistent quality, a longer shelf life, no smell, and greater stability. It’s a suitable choice for manufacturing, machinery, and other industrial applications.
