  16. 16. While plant oils such as cotton, coconut,palm, castor beans, soy, andsunflowers are also natural sources ofstearic acid,Soap making. deodorants foundationcreams, hand lotions, hair straighteningproducts, and shaving creams.
  17. 17. Biodiesel is a clean-burning fuel producedfrom plant lipids such as soybean oil and willbe a good source of feul in near future.Lubricantspalm, sunflower, soybean oils are used tomake industrial bio-lubricants. engineoil, grease and metalworking fluids.
