A lubricant composition comprising:
- 65 wt % to 95 wt % water;
- 1 wt % to 25 wt % of at least one amphoteric surfactant, wherein the at least one amphoteric surfactant is β-alanine, N-(2-carboxyethyl)N-(2-ethylhexyl) monosodium salt;
- 1 wt % to 10 wt % of at least one anionic surfactant;
- and
- 0.5 wt % to 10 wt % of at least one non-ionic surfactant.
A method of lubricating a conveyor belt, the method comprising applying a lubricant composition to the conveyor belt wherein recycled water with anions is in contact with the conveyor belt, wherein the lubricant composition has a coefficient of friction of less than 0.3 when lubricating the conveyor belt and wherein the lubricant composition comprises:
- 65 wt % to 95 wt % water;
- 2 wt % to 5 wt % N-coco, 1,3-diaminopropane;
- 0.5 wt % to 10 wt % N-lauroyl sarcosinic acid sodium salt;
- 0.5 wt % to 5 wt % of at least one non-ionic surfactant;
- 0.5 wt % to 5 wt % of a buffer;
- and
- 0.5 wt % to 3 wt % of a phosphate ester.
A lubricant composition comprising:
- 65 wt % to 95 wt % water;
- 1 wt % to 25 wt % of at least one amphoteric surfactant;
- 2 wt % to 5 wt % N-coco, 1,3-diaminopropane;
- 1 wt % to 5 wt % of at least one buffer;
- and
- 0.2 wt % to 5 wt % of at least one additive.
A lubricant composition comprising:
- 65 wt % to 95 wt % water;
- 0.5 wt % to 15 wt % of at least one cationic surfactant, wherein the at least one cationic surfactant is a diamine;
- 2 wt % to 5 wt % of at least one non-ionic surfactant, wherein the at least one non-ionic surfactant is alcohol (C13) ethoxylate (12EO);
- 1 wt % to 5 wt % of at least one buffer;
- and
- 0.2 wt % to 5 wt % of at least one additive.
