A multi-purpose lubricant is described. In accordance with one implementation, a lubricant comprises food grade based oils substantially complying with USDA H-1 specifications for incidental contact with food, wherein at least one oil is selected from the group consisting of food grade plant oil, food grade poly-alpha-olefin, polyalkylene glycol, and mixtures thereof. In accordance with another implementation, a lubricant comprises canola oil, castor oil and a poly-alpha-olefin. In accordance with yet another implementation, a lubricant comprises canola oil, castor oil and a polyalkylene glycol. In accordance with yet another implementation, a lubricant comprises an oil substantially complying with USDA H-2 specification wherein the oil is at least one item selected from the group consisting of plant oil, poly-alpha-olefin, polyalkylene glycol, and mixtures thereof. In some implementations, the multi-purpose lubricant may be applied to areas of a bicycle chain.
A lubricant comprising food grade based oils substantially complying with USDA H-1 specifications for incidental contact with food, wherein at least one oil is selected from the group consisting of food grade plant oil, food grade poly-alpha-olefin, polyalkylene glycol, and mixtures thereof, wherein the lubricant has an absolute viscosity of about 50 to 450 centipoise at about 21 degrees Celsius wherein lubricant comprises canola oil comprising about 10 weight percent to about 80 weight percent, and castor oil comprising about 10 weight percent to about 80 weight percent and the food grade poly-alpha-olefin comprises about 1 weight percent to about 10 weight percent.
A lubricant comprising canola oil, castor oil and a poly-alpha-olefin, the lubricant having an absolute viscosity ranging from about 50 centipoise to about 450 centipoise at about 21 degrees Celsius, wherein the canola oil comprises about 10 weight percent to about 80 weight percent, the castor oil comprises about 10 weight percent to about 80 weight percent and the poly-alpha-olefin comprises about 1 weight percent to about 10 weight percent.
A lubricant comprising canola oil, castor oil and a polyalkylene glycol, the canola oil comprises about 10 weight percent to about 80 weight percent, the castor oil comprises about 10 weight percent to about 80 weight percent and the polyalklene glycol comprises about 1 weight percent to about 20 weight percent—the lubricant having an absolute viscosity ranging from about 50 centipoise to about 450 centipoise at about 21 degrees Celsius.
