People may know castor oil, a thick, sticky liquid, from its use as a natural cleanser. But this oil from castor beans can be used for an amazing number of things because of the way its chemicals are made. The main reason is that it has a lot of ricinoleic acid, which is a fatty acid that isn’t usually found in plants. Castor oil can be changed into many useful goods with the help of this one special ingredient. These are called Castor Oil Derivatives.

What are Castor Oil Derivatives?

Different chemical processes create different forms of castor oil compounds. Because these changes alter the physical and chemical properties of the oil, industries and consumers can use it in many different ways.

Types of Castor Oil Derivatives

Different chemical processes change the qualities of the original oil to produce castor oil derivatives. It lets the companies that make the products change them to fit specific needs in fields like cosmetics and medicine. Here are some of the most popular things that are made from castor oil derivatives:

Hydrogenated Castor Oil (HCO)

The chemical structure of castor oil changes during the controlled process known as hydrogenation, which occurs when hydrogen gas is supplied. It produces a material with a higher melting point that is thicker and wax-like. Greases, soaps, lubricants, and coatings frequently contain Hydrogenated Castor Oil.

Castor Wax

HCO is the source of this white, odorless, flaky wax. Castor wax is useful in many fields because it doesn’t absorb water, forms films easily, and melts at a high temperature.¬†

Polyglycerol Polyricinoleate (PGPR)

When you mix simple alcohol glycerol with castor oil, you get this product. As an emulsifier, PGPR helps mix oil and water in different goods.

Sebacic Acid

This diacid, which is an organic acid with two carboxylic acid groups, comes from ricinoleic acid, which is what castor oil is mostly made of.

Undecylenic Acid

Another chemical that can be made from ricinoleic acid is undecylenic acid, which can kill fungi. Medicines used to treat fungal diseases like athlete’s foot often utilize this useful ingredient.

Ricinoleic Acid

Ricinoleic acid is a useful byproduct because it makes up most of castor oil (about 90%).

Castor Oil Ethoxylates

Castor oil is mixed with ethylene oxide to make these. Manufacturers use castor oil ethoxylates in shampoos, conditioners, and cleaning products because they effectively clean and blend ingredients together.

Sulfonated Castor Oil

Applying sulfuric acid to castor oil makes this product. Sulfonated castor oil serves as a strong cleanser and wetting agent in textile processing and industrial cleaning.

12-Hydroxy Stearic Acid (12-HSA)

12-HSA is a thickening agent that comes from ricinoleic acid and is used in many things, like makeup, lubricants, and even food additives.

Dihydroxyethyl Castor Oil (Cremophor EL)

If you’re making a product that contains oil, this water-soluble derivative can help dissolve the oil.

Polyethylene Glycol (PEG) Esters

When castor oil and polyethylene glycol (PEG) react, these compounds are formed. Depending on the length of the PEG chain, they have different qualities. Many things, like lubricants, medicines, and makeup, use PEG esters of castor oil.

Applications of Castor Oil Derivatives

As you can see, castor oil derivatives have a huge number of uses in many different fields. Let’s take a closer look at a few of their main applications:

Personal Care and Cosmetics

In the world of beauty and personal care, castor oil products are big stars. Lotions, lipsticks, and makeup get thicker and creamier with the help of hydrogenated castor oil and castor wax. Because they are natural and moisturizing, they are gentle on the face. Castor oil ethoxylates clean hair and skin in shampoos and soaps, and sulfonated castor oil makes lather that feels great. PGPR, on the other hand, makes sure that the ingredients in creams and lotions mix smoothly and evenly.

Pharmaceuticals and Medicine

Castor oil derivatives are known for their exceptional medicinal qualities. Cremophor EL helps break down drugs that don’t dissolve easily, which makes them easier to give through shots or pills. Sebacic acid may be useful in anti-aging products because it can help make skin more elastic. Castor oil derivatives play a role in creating controlled-release drug delivery devices.

Industrial Applications

Many manufacturing processes rely on castor oil derivatives. Sebacic acid is an important part of making some nylons. Many things, from clothes to engineering parts, use nylon, a flexible plastic. Ricinoleic acid is used to make high-performance lubricants for machines and tasks that need to work well in harsh conditions. Also, 12-hydroxystearic acid makes greases thicker, which makes sure they work well at high temperatures and pressures.

Textiles and Fabrics

Castor oil derivatives are also useful in the textile business. Castor oil ethoxylates help dyes stick to materials more evenly, which makes the colors deeper and brighter. For added ease, sulfonated castor oil softens fabrics, making them more comfortable to wear.

Sustainable Solutions

As people become more concerned about the environment, they can use products made from castor oil instead of products made from gasoline. Castor wax, which is recyclable, is used instead of petroleum wax in candles and beauty products. Some products made from castor oil can also be used as bio-lubricants, which are better for the environment than regular lubricants.


People used to mostly use castor oil as a cleanser, but now they use it as an ingredient in a huge variety of castor oil derivatives. In our daily lives, these versions are very important. Many things use them, such as the clothes we wear and the medicines that keep us healthy. There’s a good chance that a castor oil derivative is doing something important and hidden the next time you buy makeup or polish your car.
