Abstract
A lubricant composition is provided for use in lubricating a conveyor track for bottles, cans, kegs and other containers for beverages and foodstuffs. The composition comprises a phosphate ester of the formula R1—(OCH2CH2)n—O—P(O)(OH)2 where n is in the range of from 0 to 10, and R1 is a C9 to C20 saturated or unsaturated alkyl group or a mixture of such alkyl groups; and water. The composition has a pH of from about 1 to about 3.5. The composition optionally further comprises a biocidal agent, an acid, and a synthetic surfactant. Also disclosed is a method for lubricating a conveyor track by applying an effective amount of such a lubricating composition.
Claims25
A lubricant composition for use in lubricating a conveyor track, said composition comprising:
- (a) from about 1% to about 50% by weight of a phosphate ester of the formula
- R1—(OCH2CH2)n—O—P(O)(OH)2
- wherein n is from 0 to about 10, and R1 is a C9 to C20 saturated or unsaturated alkyl group or a mixture of such alkyl groups;
- and
- (b) water;
- said composition having a pH of from about 1 to about 3.5.
A composition according to 1 having a pH of from about 1 to about 3.
A composition according to clam 11 comprising from about 1% to about 5% of a biocidal agent.
A lubricant composition for use in lubricating a conveyor track, said composition comprising:
- (a) from about 5% to about 30% by weight of a phosphate ester of the formula
- R1—(OCH2CH2)n—O—P(O)(OH)2
- wherein n is from 0 to about 10, and R1 is a C9 to C20 saturated or unsaturated alkyl group or a mixture of such alkyl groups;

- (e) from about 1% to about 5% of a biocidal agent.
- said composition having a pH of from about 1 to about 2.5.
A method for lubricating a conveyor track by applying to the track an effective amount of a lubricating composition comprising:
- (a) from 0.01% to about 50% by weight of a phosphate ester of the formula
- R1—(OCH2CH2)n—O—P(O)(OH)2
- wherein n is from 0 to about 10, and R1 is a C9 to C20 saturated or unsaturated alkyl group or a mixture of such alkyl groups;
- and
- (b) water;
- said composition having a pH of from about 1 to about 4.
