Grease is a thick oily substance which is commonly used as a lubricant. It consists of a petroleum-derived or synthetic oil which is held in place by the gel structure of a thickening agent. It’s typically formed of these three components, which keep it in a semi-solid state:
- Thickener – 5% to 20%
- Base oil – 80% to 95%
- Additives – 0% to 10%
