Candle nut (Aleurites moluccanus) is also known as kemiri in Indonesia and kukui Hawaii. The candlenut tree (Aleurites moluccana L. Wild)—found in tropical subcontinents—belongs to the Euphorbiaceae family and is a multipurpose tree native to the Indo-Malaysia region.

The seeds are toxic when raw, but edible when dried in small quantities. Candlenut have been used as a source of oil for cosmetic. Candlenuts contain nutrients and non-nutrients such as saponins, flavonoids, polyphenols, vitamins, folate, protein, and carbohydrates. The micronutrients contained in candlenut consisted of minerals such as potassium, phosphorus, magnesium, calcium, iron, zinc, copper and selenium.

The species has been used for various purposes; for an instance, the seeds can be used as media for lighting, cooking and medicine and the stems can be used for wood. Previous research on its pharmacological use found that candlenut is also prospective medicine for ulcers, headache, fever, diarrhea and hypocholesterolaemia and many more.

Approximately 60% of the candlenut seed is oil, which is obtained using several extraction techniques. Candlenut oil has a high iodine number (≥125) and lower pour point and is primarily for cosmetics, varnishes, paints, and high-quality biofuel production.

The candlenut oil contains 15% oleic acid, 40% linoleic acid, and less than 30 % linolenic acid, it contains high unsaturated fatty acids, which is a prospective raw material for epoxidation.
