Abstract
A method of lubricating conveyor tracks or belts is herein described wherein the lubricant composition contains a polyalkylene glycol polymer, a fatty acid, and an anionic surfactant; also described is a lubricant composition with reduced sensitivity to low pHs. The composition may also comprise additional functional ingredients and be composed of ingredients that can be safely administered to humans and mammals.
Claims31
A method of lubricating a moving surface for conveying food or beverage, the method comprising:
- a) providing a moving surface;
- b) providing an acidic beverage;
- c) providing a lubricant composition comprising:
- i) a fatty acid;
- ii) a polyalkylene glycol polymer;
- iii) an anionic surfactant selected from the group consisting of sulfates, sulfonates, sulfosuccinates, sulfosuccinamates, sulfonated ester, sulfonated amides, and mixtures thereof, and
- iv) a solvent, and
- d) applying the lubricant composition to the moving surface.
A method of lubricating a moving surface for conveying food or beverage, the method comprising:
- a) providing a moving surface;
- b) providing an acidic beverage;
- c) providing a diluted lubricant composition comprising:
- i) from about 0.0001 to about 50 wt. % of a C8–C20 fatty acid;
- ii) from about 0.001 to about 50 wt. % of a polyalkylene glycol polymer;
- iii) from about 0.0005 to about 25 wt. % of an anionic surfactant selected from the group consisting of sulfates, sulfonates, sulfosuccinates, sulfosuccinamates, sulfonated ester, sulfonated amides, and mixtures thereof;
- and
- iv) a solvent, wherein the diluted lubricant composition maintains lubricity in the presence of the acidic beverage;
- and
- d) applying the lubricant composition to the moving surface.
A method of lubricating comprising:
- (1) mixing a lubricant for application on to a moving surface for conveying food or beverage comprising:
- a) providing
- i) a fatty acid;
- ii) a polyalkylene glycol polymer;
- and
- iii) an anionic surfactant selected from the group consisting of sulfates, sulfonates, sulfosuccinates, sulfosuccinamates, sulfonated ester, sulfonated amides, and mixtures thereof;
- and
- b) combining the fatty acid, the polyalkylene glycol polymer, and the anionic surfactant to form a lubricant concentrate at the location where the lubricant is to be used,
- wherein the lubricant concentrate maintains lubricity in the presence of an acidic beverage;
- and
- (2) applying the lubricant concentrate to a moving surface.
