Castor or Castrol?

I remember one customer I had last year who, upon hearing the ingredients of my soap, stopped, and was aghast. He asked in a concerned voice, “why the heck would you put castor oil in soap? Don’t you know it’s for cars?”

After explaining the benefits of castor oil, he went on his way. It was only then that I realized that he was probably thinking of Castrol oil, not Castor oil. :-D

So, no, Castor oil is not motor oil. That stuff has no use in soap.

Castor oil is a vegetable oil. A colorless liquid pressed from Castor beans.

Castor oil is well known as a source of ricinoleic acid, a monounsaturated, 18-carbon fatty acid. It is a very unique fatty acid, that is more polar than most fats.

It has the advantageous ability to control the amount of bubbles that are produced in the soap, which I find very cool indeed.

Because the oil is so silky smooth, and its molecular structure is such that it can react with other materials to produce many chemical compounds that have numerous applications, it can be turned into a specialized lubricant for jet engines and racing cars, and this is probably where the confusion lies. Castrol took its name from Castor oil.

Another thing that some people may remember is Castor oil used to be used a lot as a laxative, or a medicine before surgery, or even as a form of punishment. So, it kind of got a bad name over the years.

However, I’m happy to share with you the following amazing benefits of Castor oil in my soap…

• Moisturizing Properties:

  Castor oil is rich in fatty acids, especially ricinoleic acid, which acts as a natural emollient. It helps to lock in moisture, leaving the skin hydrated and supple.

• Anti-inflammatory Effects:

  The compounds in castor oil can reduce inflammation, making it beneficial for sensitive or acne-prone skin. It can soothe redness and irritation, and provide relief from conditions like eczema and psoriasis.

• Antimicrobial Properties:

  Castor oil contains undecylenic acid, which has antimicrobial activity against various strains of bacteria and fungi. This makes castor oil soap effective in removing dirt, bacteria, and impurities from the skin.

• Enhanced Lather:

  Castor oil can improve the lather of soap, giving it a luxurious texture and helping to lift dirt and impurities more effectively.

• Anti-aging Benefits:

  It promotes the production of elastin and collagen, which may help to delay the appearance of wrinkles and fine lines.

• Acne Control:

  Its antimicrobial and anti-inflammatory properties can help in the battle against acne, clearing out impurities and reducing inflammation.

• Hair Nourishment:

  When used in shampoo bars, castor oil can nourish the scalp and hair follicles, encouraging healthy hair growth.

• Dandruff Control:

  Its anti-fungal properties make it effective against dandruff, providing relief from itching and flakiness.
