Abstract
A cleaning composition is disclosed comprising a method of cleaning a substrate to remove a residue from the substrate by using a cleaning composition comprising (a) a decarboxylated rosin acid (DCR), and (b) optionally a diluent. The residue is selected from soil, dirt, sand, food, oil, grease, paint, ink, glue, adhesive, sealant, wax, tar, graffiti, asphalt, buffing compounds, cutting fluids, and mixtures thereof. At least 0.3 wt.% of the residue is removed from the substrate per cleaning cycle, based on total weight of the residue present on the substrate. The cleaning composition is stable and is effective in removing the residue from hard or soft substrates.
Claims20
A method of cleaning a substrate to at least partially remove a residue from the substrate, comprising:
- contacting at least a portion of the residue on the substrate with a cleaning composition, wherein the cleaning composition comprises:
- (a) a decarboxylated rosin acid (DCR) having a density of 0.9 to 1.0 g/cm3, a flash point of 135 to 175° C., an acid value of <50 mg KOH/g, measured according to ASTM D465, and a viscosity of 15 to 60 cSt at 40° C., measured according to ASTM D-445;
- and
- (b) optionally a diluent;
- removing at least a portion of the cleaning composition along with at least a portion of the residue from the substrate;
- wherein the residue is selected from the group consisting of soil, dirt, sand, food, oil, grease, paint, ink, glue, adhesive, sealant, wax, tar, graffiti, asphalt, buffing compounds, cutting fluids, fat, sludge, and mixtures thereof;
- wherein at least 0.3 wt.% of the residue is removed from the substrate per cleaning cycle, based on total weight of the residue present on the substrate, measured as described in a Scrub Test.
