Black Castor Oil is produced from the same plant as standard Castor oil. However, as the seeds are roasted before extraction, the oil has a dark burnt orange/reddish-brown colour with a stronger, more nutty aroma.
The slight ash content of the oil is said to offer additional benefits for hair - especially for those with thicker or more curly hair types.
Castor oil is actually soluble in alcohol and creates a unique solubility with beeswax, which is why it is used so much in balms and deodorants. It has a low molecular weight and so penetrates the skin easily, and acts as a softening agent. It is a greasy feeling oil with a lot of shine, but can feel sticky which is why it is used in lipsticks – the added gloss enhances the appearance of the finish and its stickiness helps to keep the oil on your lips without feathering into fine lines. It is low comedogenic (1 out of 5) and non-irritating. It has an acanthotic activity, meaning it can help increase skin thickness.
Ricinoleic acid is soluble in alcohol (but not water) and oil. It acts as a humectant and helps make Castor a 'dry' oil as well as increasing its viscosity.
As this is a cold-pressed oil, no solvents such as hexane were used in the extraction process.
