Benefits Of Hydrogenated Castor Oil for Skin Care

Over the last few years, the organic obsession has revived our interest in botanical skincare.

With a plethora of nicely packaged oils to easily introduce oneself to, it seems there is one for every occasion.

Yet little is known about castor oil, this quiet, unsung hero.

It has been around for a while, but we’re only beginning to appreciate its work’s scope.

Its pure form has many benefits for the skin, hair, and lips.

We’ve long touted the wide-ranging benefits of rosehip, avocado and, coconut oil, castor oil.

Yet castor oils long list of uses have been left out of the beauty oil buzz.

Well, we folks at NC are just about to change all that.

Hydrogenated Castor Oil

What is castor oil?

The oil is extracted from the castor plant’s tough, thorny shrub; the seeds are cold-pressed, producing this lovely, thick oil that has a lot of shine.

It is compatible with beeswax, which is why you will see it often used in lipsticks and balms, combined, they work to keep the oil on your lips and prevent them from feathering into fine lines.

It has a low molecular weight, so it penetrates the skin easily; it acts as a softening oil and is nourishing.

It has a fascinating fatty acid profile, containing around 6% oleic acid, 4% linoleic acid, and 90% ricinoleic acid.

Ricinoleic acid: This is an unusual fatty acid that balances transepidermal water loss in the skin tissues, making it an important humectant. Ricinoleic acid is considered an analgesic and anti-bacterial. There are indications it may act as an anti-fungal. For these reasons, it is sometimes used to treat various skin conditions, including eczema, acne, and psoriasis.
Phytosterols: Castor oil contains phytosterols in the form of ß-sitosterol, campesterol, and stigmasterol, which is where it gets its anti-inflammatory and anti-itch properties, helping to end the cyclical nature of itching and irritation.
Acanthotic: If all of that isn’t enough, castor is unusual because it has ‘acanthotic activity’, meaning it can help increase the thickness of your skin.

We include castor in our Miracle cleanse designed to protect as it cleanses, offering healing, and regenerative nourishment to dry sensitive skin.

Castor doesn’t have the best slippage on the skin and can be quite tacky to touch, which can put people off. Castor oil is referred to as a thick oil in the cosmetic industry due to its viscosity of around 293. Compare this to olive oil, which has a viscosity of 47, and you can see why it’s so thick.

The beautifying benefits of castor oil

We think castor oil is underestimated; look at some of its awesome skin benefits:

Anti-viral and anti-bacterial properties: The triglycerides found in castor can help to fight skin infections.

Anti-inflammatory: The oil is well-known for its healing properties against eczema, dermatitis, rosacea, and psoriasis. It is the perfect antidote if you have irritated, inflamed skin. Its anti-inflammatory properties help to calm and soothe your sensitive skin.

Anti-microbial: Hydrogenated castor plays a protective role on your skin, keeping invading pathogenic bacteria at bay.

Anti-Acne: One of the main benefits of castor oil is that it retards the growth of harmful microbes; this is due to ricinoleic acid; a potent fatty acid that helps to protect your skin against invading viruses and bacteria. It inhibits the growth of P Acnes bacteria that lead to acne breakouts. The antimicrobial and anti-inflammatory properties of castor oil also make it useful in reducing acne.

Anti comedogenic: That, coupled with the fact that it is low comedogenic, makes it an interesting oil when treating acne.

The fact that it is low on the comedogenic scale means it won’t congest or annoy skin suffering from pimples, pustules, and papules, which often have inflammation.

Anti-ageing: Castor oil is a penetration enhancer. It penetrates deep and helps to boost the body’s production of collagen.

Our collagen reserves deplete with age—especially in delicate areas where the skin is thinner on the face, such as around the eyes and mouth, where expression lines tend to appear first. To help prevent this, pour a small amount onto a cotton pad and apply it to your skin at night before sleeping.

Cleansing: The triglycerides found naturally in castor oil help remove dirt from your skin.

Dispersant: Another interesting fact about castor oil is that when it has been hydrogenated, it forms the base of a common dispersant in water, making it a great carrier for essential oils in bath oil.

Hydrating: As discussed above, because of humectant-rich ricinoleic acid, Castor oil works as a natural humectant, pulling moisture from the air and trapping it close to your skin’s tissues.

Improves Texture: Castor is rich in oleic and linoleic acid. These wonderful fatty acids are perfect for softening and soothing dry, parched skin.

Moisturising: The triglycerides present in hydrogenated castor oil for skin help to restore the skin’s natural moisture balance, making it a perfect ingredient if you have dry skin conditions.

We could hardly overlook this potent ingredient with a list of benefits like this.

As you can see, the benefits of castor oil in skincare are vast.

However, there has been limited research into topically applying castor oil’s dermatological benefits. Therefore, we recommend implementing oil alongside your other skincare products when treating specific skin conditions.

Sadly it is worth mentioning, as, with most things in nature, castor oil is subject to refining, which robs the oil of its important properties.

Ideally, the only castor oil you should use in your skincare should be the cold-processed variety, which retains many nutrients and doesn’t lose its important skincare properties or medicinal value.

I have been using organic cold pressed castor oil on my melasma for 6 months now and it has almost completely removed the dark patches on my face. I rubbed it into my skin, especially on affected areas every night before bed.


This is a really interesting case study, any further information that could help my readers or if you would like to include a paragraph I could add to my article that would be really welcome. Samantha

Mrs. Samantha Miller
Frankly, thanks to your text, you evidently contribute to the great value of Castor Oil.

Hi Jean

Thank you so much, because of my love for Castor oil I think it’s important to make this information readily available for my readers, I appreciate your comments thank you.

Kind Regard


As I’ve been getting older I’ve noticed that the outer parts of my eyebrows have started thinning (a lot). I read that using castor oil could help the hair grow back. I started rubbing a little into my eyebrows at bedtime every night and I honestly see a difference. It’s not a tonne yet but it’s coming. I also noticed that it’s making my eyebrows a bit darker. I will continue to use it because I’m very happy with the results. After reading this I think I’m also going to try it for washing my face. I’ve used sweet almond oil with a few drops of lavender and 1 drop of frankincense for a while now but I’m still finding parts of my face are slightly dry. Maybe this will be what I need. Thanks for the information.

Hi Kim.
I would love to know the long term results in the future. Thinning eyebrows in the outer parts can indicate a thyroid problem not sure if you are aware of that. Thanks for reaching out..kind regards Samantha

Wow!! Castor oil really makes me feel good on my face… All my acne on my face vanished and my skin looks healthy now. This is really a wonderful product that work to treat many skin problems naturally.

Harvey, I don’t acceptspam sorry so have removed the link. However I will keep your comment because there are some wonderful properties in castor oil that should not be ignored, not sure if treating acne is one of the benefits, but I will take your word for it.Samantha

Love your detailed information on Castor Oil. It’s the only thing I use for makeup removal and for moisturizing my skin from scalp to toes (including hair).

I’m not sure why others claim it’s ‘drying’ to skin, but that’s certainly not the case for me and I’ve found that when I massage it into my skin, it does actually absorb after some time, leaving skin feeling baby soft.

Your blog posts are wonderful! I am a passionate skincare advocate making the turn to a holistic, all natural approach to beauty after years in the prestige beauty industry. I am hungry for education on the topic and a have found your site to be one of the best! I recently started a cleansing regimen with Castor Oil. I haven’t used a traditional soap or facial cleanser on my face in a month. My skin looks great! Pore less, calm, plump.

Thank you for the education … I look forward to reading more posts!

Rachel thankyou so much for the inspiring message and taking the time to write. Knowledge is what essentially life is all about and its great for me to have a medium to do it through. I am so glad you have come across the many benefits of castor oil, its funny how it goes largely unnoticed by the skincare industry! Another friend of mine just uses pure aloe out of the plant for everything skin and hair and her skin looks fantastic ..inspires me to write a post called the one ingredient love for the future.Samantha x

I was really happy to come across your website, so useful..It would be great to chat ot you more about skincare, such a fascinating subject.

with best regards

I was happy to find you as I too share your passion. I have skin care products, one kind of which are bath oils that are to be water-dispersant. Does it have to be 100% castor oil for my bath oil products are do I dilute it in carrier oils such as Grapeseed or a combination of other oils???

One more question about my castor oil I bought almost a year ago….I don’t know if it smells rancid or not since I’m not sure what castor oil is supposed to smell like especially as this is “red turkey” castor oil. Do you know?

Thanks a lot,
