Heavy Duty Laundry Liquid

Start the LAS-99 addition. Add only 50% of the Sulfonic Acid. 4 Add the Caloxylate N-9 to aid in fluidizing the neutralization 

Carbopol ETD 2691 is to provide product phase stabilization in this high alkalinity industrial strength cleaner. 

Use a Lightnin Mixer or similar variable speed unit and an impeller suitable for general mixing and blending operations. Screen the Carbopol resin into the vortex of the rapidly agitating water (BOO rpm). Allow to mix until homogeneous and free of polymer lumps. 

With slow mixing, add in the alcohol ethoxylate and alkylbenzene sulfonate surfactants. 

Add in the pyrophosphate with minimal agitation to avoid air entrapment.

Heavy-Duty Liquids, Heavy-duty laundry liquids have gained much importance and much interest in the literature over the last few years. Products in the industry today include both built and nonbuilt heavy-duty liquids. Built heavy-duty liquids are those which contain a builder such as tetrapotassium pyrophosphate (TKPP) or sodium citrate in order to sequester calcium and magnesium hardness ions. Nonbuilt heavy-duty liquids contain no builders and make up for that shortage by considerably increased active contents in order to maintain performance(8-14). Built heavy-duty liquids can have either of the following types of formulations ... 

Enzymes are highly susceptible to degradation in heavy-duty laundry liquids. With the increasing emphasis on the use of enzymes as cleaning agents, it becomes all...

Nonionic surfactants are increasingly popular active ingredients for liquid heavy duty laundry detergent formulations. The majority of nonionic surfactants are polyoxyethylene or polyoxypropylene derivatives of alkyl-phenol, fatty acids, alcohols, and amides. It has been estimated that approximately one ethylene oxide unit is required to solubilize each methylene unit. Thus, by changing the ratio of ethylene oxide to fatty acid, the nature of the surfactant can be modified from an... 

Sodium tripolyphosphate is the major builder ingredient in heavy duty laundry detergents, automatic dishwashing compounds, and industrial and institutional cleaners. In liquid consumer laundry detergents, sodium citrate has displaced tetrapotassium pyrophosphate (K4P2O7—TKPP), but TKPP use in industrial and institutional liquids is preferred because of its superior solubility and sequestration characteristics.

Again, the optimum nonionic of choice for this application will depend upon the type of soil to be removed in the laundry process. For example, Figure 3 shows the optimum nonionic for removing typical sebum soil (body oil) in a nonbuilt heavy duty liquid. This figure shows that the optimum lies in the circle between and C., alcohol at an ethylene oxide level of 60 to oO percent. The peak of this optimum would be in the vicinity of a alcohol with 70 percent EO. This is considerably higher in EO content than the ethylene oxide optimum found for powdered laundry detergents. 

Citric acid is used in soft drinks, candies, wines, desserts, jellies, jams, as an antioxidant in frozen fruits and vegetables, and as an emulsifier in cheese. As the most versatile food acidulant, citric acid accounts for about 70 percent of the total food acidulant market. It provides effervescence by combining the citric acid with a biocarbonate/carbonate source to form carbon dioxide. Citric acid and its salts are also used in blood anticoagulants to chelate calcium, block blood clotting, and buffer the blood. Citric acid is contained in various cosmetic products such as hair shampoos, rinses, lotions, creams, and toothpastes. More recently, citric acid has been used for metal cleaning, substituted for phosphate in detergents, for secondary oil recovery, and as a buffer/absorber in stack gas desulfurization. The use of sodium citrate in heavy-duty liquid laundry detergent formulations has resulted in a rapid increase in the use of citric acid.
