Definitions

• the present invention relates to cleaning agents, and more particularly to a chemical composition for use as a cleaning, wetting agent and solvent and in other suitable applications.
• solvents are used in textile industry and act as wetting agents in a process designed to remove sizing from cloth before the fabric is dyed or printed.
• Electronic circuit printboards have to be regularly cleaned to prevent disfunction of the electronic device due to accumulation of dust or other foreign material on the surface.
• the present invention contemplates provision of a cleaning, wetting solvent agent which is non-toxic, non-flammable and economical, which does not deplete the ozone layer.
• Still a further object of the invention is to provide a dispersant which maintains a buoyancy effect on dispersed hydrocarbons, making collection and disposal of contaminants easier and more cost-effective.
• composition of matter which comprises dodecylbenzenesulfonic acid, ethoxylated nonyl phenol, lauric acid diethanolamide, diethanolamine and propylene glycol mixed in a water base.
• the composition of matter provides for a mixture in water of between about 0.17% and 1.36% by total weight of ethoxylated nonyl phenol, mixed with dodecylbenzenesulfonic acid in an amount between about 2 and 2.5 times the concentration of ethoxylated nonyl phenol, lauric acid diethanolamide in amount between about 1.5 and 2 times the concentration of the dodecylbenzenesulfonic acid, and diethanolamine and propylene glycol in equal amounts of between about 2 and 2.5 times the concentration of lauric acid diethanolamide.
• composition of matter provides for the use of 3% by total weight of dodecylbenzenesulfonic acid, 0.3% by total weight of ethoxylated nonyl phenol, 5.66% by total weight of lauric acid diethanolamide and equal amounts of 2.46% by total weight of diethanolamine and propylene glycol all mixed in a water base.

• EXAMPLE 3 25.07% of water was deposited in a vat. In a separate vat 12% by weight of dodecylbenzenesulfonic acid was premixed with 1.36% by weight of ethoxylated nonyl phenol. The mixture was thoroughly blended and then deposited into the first vat containing water. While continuously stirring the following ingredients were added to the first vat: 22.64% of lauric acid diethanolamide, 9.84% by weight of diethanolamine and 9.84% by weight of propylene glycol. Finally, 19.25% by weight of water was added to the mixture which was stirred for an additional 15 minutes.
