  • Cottonseed Oil

  • Latin Name
    Gossypium barbadense ( plus various species)
    family; Malvaceae
  • Etymology
    From the latin gossypinus, gossypium-like, cotton-like
  • The plant and its Environment
  • Originally grown in India for the cotton fibre, the plant was introduced into China and Egypt about half a millennium BC and into the USA much later in 1774. There was a species grown in Peru predating the Egyptian cotton industry and the use of cottonseed oil is mentioned in ancient Hindu writings. The plant forms a shrub growing to a height of 1.5 meters, bearing yellow flowers with a purple centre which lead to capsules containing the seeds and covered with trichomes, which are the source of cotton fibre.
  • The OIl
  • In Britain cottonseed oil used to be about 15% of the vegetable supply:; in 1956 it was less than 3%. Cottonseed oil is obtained from the seeds of Gossypium barbadense and other varieties: it is a bland, flavourless oil not liable too rancidity, being used for a great many purposes  for external applications. Some seeds are almost bald and are known commercially as 'black' whereas others have a wooly lint on the outside and are known as 'white'; the former obviously produce more oil per seed weight  (approximately 20-25%). Cottonseed oil has properties similar to Hibiscus sabdariffa (malvaceae) which is used as a substitute for crude castor oil (duke 1985)


  • Method of Extraction
    This oil is not expressed at high pressure (1500 pounds per square inch)resulting in a thick crude oil which must be refined.

  • Cosmetic Use
    Cottonseed oil is inexpensive and therefore it is used widely in soaps, creams, baby creams, nail polish and lubricants. It is not suitable for aromatherapy.
    Culinary Use
    As it is cheap it is used in salad oil and for frying fish.
    Cautionary Notes
    Cottonseed oil is known to cause allergies, but it is difficult to avoid this much used oil because it is so widely used in cosmetic preparations. The oil is cathartic, abortifacient; no part of the plant should be used internally unless prior medical advice is obtained.
