them to reduce friction, heat, wear-and-tear and energy consumption. this can be accomplished by using oils, greases, gases or other fluids. grease is composed of oil and a thickening agent to maintain its consistency, while the oil is what actually lubricates. oils can be synthetic, vegetable or mineral-based...
where facilities for natural retting do not exist. either dry or green husks are soaked in cement tanks for a period varying from a few hours to three weeks and the fiber extracted manually or mechanically. in one method, the husks are first crushed through a series of corrugated iron rollers, a machine...
contributes to unhairing, as it tends to break down the hair proteins. liming unhairing agents used at this time are: sodium sulfide, sodium hydroxide, sodium hydrosulfite, calcium hydrosulfide, dimethyl amine, and sodium sulfhydrate. the majority of hair is then removed mechanically, initially with a machine...

although edible oils are secondary products derived from the processing of crops there will be some carry over of pesticide residues into the oil. some countries have specific limits for specific pesticides but in any case all pesticides may be covered by the catch-all regulation banning harmful substances...
