Palm kernel oil soap making: a good soap must contain at least 15 per cent laurate for quick lathering, while soap made for use in sea water is based on virtually 100 per cent laurate. Derivatives of palmitic acid were used in combination with naphtha during World War II to produce napalm (aluminum naphthenate and aluminum palmitate). Palm kernel oil Palm kernel oil is an edible plant oil derived from the kernel of the oil palm "Elaeis guineensis". It should not be confused with the other two edible oils derived from palm fruits: palm oil, extracted from the pulp of the oil palm
Rendering (animal products) separates the fat from the water. The solids may be used in food products, pet foods, etc., depending on the original materials. The separated fat may be used in food products, or if in surplus, may be diverted to soap making operations. Most edible rendering is done by meat packing or processing companies. One edible product is greaves, which is the unmeltable residue left after animal fat has been rendered. An alternative process cooks slaughterhouse offal to produce a thick, lumpy "stew" for the pet food industry, which uses it principally in tinned cat and dog foods. Such plants are
