Palm oil is one of the most widely used natural vegetable oils globally, possessing stable oxidation resistance, rich saturated and unsaturated fatty acid composition, and excellent thermal stability suitable for high-temperature processing. It is largely applied in the food industry as raw material for edible cooking oil, frying oil, margarine, shortening, bakery products, instant noodles, confectionery and cream substitutes, providing good flavor stability and prolonging shelf life of processed foods. In the oleochemical industry, it serves as basic raw material for producing fatty acid, fatty alcohol, glycerin and soap base, widely used in the manufacturing of laundry soap, detergent, surfactant and cosmetic raw materials such as cream, lotion and lipstick. It is also commonly used as feed oil additive to improve animal energy intake and growth efficiency in livestock and poultry breeding. Furthermore, it can be processed into biodiesel and industrial lubricant base oil, playing an important role in new energy development and industrial auxiliary material production.

Palm oil is a natural edible oil with low acute toxicity and generally safe under normal use and edible dosage. Direct prolonged skin contact may cause mild greasiness, pore blockage or slight allergic reaction for sensitive skin groups; splashing into eyes may cause foreign body sensation, blurred vision and mild conjunctival irritation. Inhalation of heated oil fume for a long time may irritate respiratory tract mucosa and cause throat discomfort or dizziness. Overconsumption for a long period may lead to excessive calorie intake and affect blood lipid metabolism. During industrial handling, operators should wear protective gloves and splash-proof goggles, avoid inhalation of hot oil vapor, and keep working area ventilated. Store in sealed, cool, dry and dark warehouse, away from high temperature, open fire and strong oxidants to prevent oxidation rancidity. Waste palm oil shall be recycled and disposed of by professional units, and shall not be randomly discharged to avoid polluting water bodies and causing environmental oil contamination.
