Abstract
The present invention provides stable water-in-oil emulsions suitable for use as fire-resistant aerosol multipurpose lubricants. The water-in-oil emulsion comprises a synthetic ester base oil, compatible invert emulsifier, water, and a preservative. The aerosol apparatus employs a larger than standard stem orifice to produce a non-flammable aerosol.
Claims28
A method of making an invert emulsion lubricating composition, the method comprising:
- (A) adding an ester base oil and a water-in-oil emulsifier into a reaction vessel;
- (B) homogenizing the ester base oil and the water-in-oil emulsifier;
- (C) adding water into the reaction vessel;
- and
- (D) homogenizing the mixture in the reaction vessel until all the water is emulsified and no residual water is left at the bottom of the reaction vessel,
- wherein the invert emulsion lubricating composition comprises the ester base oil at about 25% to 55% by weight, the water-in-oil emulsifier at about 2% to 14% by weight, and water at about 35% to 65% by weight.
