Abstract
Household lubricant compositions containing medium chain triglycerides are non-toxic and biodegradable. The lubricant compositions are made using vegetable oil components and stabilized using alcohol, an antioxidant, and a metal chelator. The lubricant compositions offer safe and environmentally friendly alternatives to petroleum-based lubricants, yet have similar lubricity and are more stable than naturally sourced vegetable oils. The compositions also can be used to clean and coat surfaces, including food preparation surfaces, and to prevent corrosion. Still further uses include sterilization and sanitation of surfaces and as a skin conditioner and lubricant.
Claims25
A chemically stabilized household lubricant and coating composition comprising:
- (i) a medium chain triglyceride (MCT) oil at a concentration of from about 20 weight percent to about 80 weight percent;
- (ii) anhydrous alcohol at a concentration of from about 20 weight percent to about 80 weight percent, wherein the anhydrous alcohol is selected from the group consisting of ethanol, n-propanol, and isopropanol;
- (iii) an antioxidant at a concentration of from about 50 to about 500 ppm;
- and
- (iv) a metal chelating agent at a concentration of from about 20 to about 200 ppm;
- wherein the melting point of the composition is below 0° C.;
- wherein the kinematic viscosity of the composition is less than about 20 centiStokes (cSt) at 40° C. or less than about 40 cSt at 20° C.;
- and
- wherein the composition forms a single homogeneous phase at ambient temperature.
