Abstract
A composition that optimizes the performance and maintenance of halogenated dry cleaning solvents is disclosed. One embodiment of a detergent composition for use with halogenated dry cleaning solvents includes water, a surfactant, a solubilizer, a coupling agent, an acid-accepting stabilizer, and a halogenated solvent. Optionally, the composition can include an oil-based fragrance and/or an optical brightener. When used in a dry cleaning process, the detergent composition replenishes the acid-accepting stabilizer depleted from the dry cleaning solvent and the halogenated solvent suppresses the flash point of the acid-accepting stabilizer.
Claims18
A detergent composition for use with halogenated dry cleaning solvents, comprising:
- water;
- a surfactant;
- a solubilizer comprising an alcohol selected from the group consisting of methanol, ethanol, isopropanol, n-propanol, and mixtures thereof;
- a coupling agent comprising an alkylene glycol;
- an acid-accepting stabilizer comprising an epoxide;
- and
- a halogenated solvent.
A detergent composition for use with halogenated dry cleaning solvents, comprising:
- about 10 wt. % to about 90 wt. % water;
- about 1 wt. % to about 60 wt. % of a cationic surfactant or a blend thereof,
- about 0.1 wt. % to about 5 wt. % of an alcohol solubilizer selected from the group consisting of methanol, ethanol, isopropanol, n-propanol, and mixtures thereof;
- about 1 wt. % to about 20 wt. % of an alkylene glycol coupling agent;
- about 1 wt. % to about 10 wt. % of an acid-accepting epoxide stabilizer selected from the group consisting of 1,2-epoxybutane, pentylene oxide, hexylene oxide, and mixtures thereof, and,
- about 1 wt. % to about 30 wt. % of n-propyl bromide;
- wherein the weight percentages are expressed relative to the weight of the detergent composition.
A detergent composition for use with halogenated dry cleaning solvents, comprising:
- about 34 wt. % water;
