Abstract
A biobased penetrating oil for use to reduce friction between fittings. The penetrating oil composition preferably contains one or more long-chain, low-volatile esters specifically derived from a natural plant-based oil, such as a combination of methyl esters derived from soybean oil, and an unsulfurized terpene, such a pine oil or limonene and various orange terpenes as a solvent. The penetrating oil can be an aerosolized product and included a carbon dioxide propellant.
Claims20
A penetrating oil composition comprising:
- a) greater than 50 weight percent of a long-chain, low-volatile ester or combination of esters derived from a natural plant-based oil;
- b) 20 to 40 weight percent of an unsulfurized terpene;
- c) 1 to 10 weight percent of a rust preventative, and
- d) 1 to 10 weight percent of a propellant.
A penetrating oil composition comprising:
- a) a combination of long-chain, low-volatile esters derived from a natural plant-based oil, said combination being greater than 50 weight percent, said combination being
- 5 to 9 weight percent hexadecanoic acid methyl ester,
- 2 to 4 weight percent octadecanoic acid methyl ester,
- 12 to 20 weight percent 9-octadecenoic acid (Z) methyl ester,
- 25 to 45 weight percent 9,12-octadecadienoic acid (Z,Z) methyl ester, and
- 3 to 6 weight percent 9,12,15-octadecatrienoic acid (Z,Z,Z) methyl ester,
- b) 20 to 40 weight percent of at least one terpene, and
- c) 1 to 10 weight percent of a rust preventative.
A penetrating oil composition comprising 60 to 80 weight percent of soybean methyl ester, 18 to 22 weight percent of unsulfurized orange terpene, 2 to 5 weight percent of a rust preventative and less than 5 weight percent of propellant.
