Degreasing agents

To rinse, wash the surface in clear, continuous running water to remove all traces of degreasing agent from the surface. Two/three dips at room temperature are sufficient. 

Chemical compounds manufactured at petrochemical plants include methanol, formaldehyde, and halogenated hydrocarbons. Formaldehyde is used in the manufacture of plastic resins, including phenolic, urea, and melamine resins. Halogenated hydrocarbons are used in the manufacture of silicone, solvents, refrigerants, and degreasing agents. 

Entfettungsmittel, n. scouring agent, degreasing agent Med.) remedy for obesity. Entfeuchter, m. desiccator, entfilzen, t.t. unfelt. 

Cresylic acid is mainly used as degreasing agent and as a disinfectant of a stabilized emulsion in a soap solution. Cresols are used as flotation agents and as wire enamel solvents. Tricresyl phosphates are produced from a mixture of cresols and phosphorous oxychloride. The esters are plasticizers for vinyl chloride polymers. They are also gasoline additives for reducing carbon deposits in the combustion chamber. 

Perchlor and trichlor are used as metal degreasing agents and as solvents in dry cleaning. Perchlor is also used as a cleaning and drying agent for electronic equipment and as a fumigant. 

Other uses of ethylene dichloride include its formulation with tetraethyl and tetramethyl lead solutions as a lead scavenger, as a degreasing agent, and as an intermediate in the synthesis of many ethylene derivatives.

NPE was previously used extensively as nonionic surfactants and emulsifiers in both the textile and the leather industry but has now been replaced by alternative surfactants in Europe. The main alternatives in the leather industry are linear alcohol ethoxylates with different chain lengths and ethoxylation degrees. These compounds are much easier than NPE degraded to non-toxic compounds. The efficiency of linear alcohol ethoxylates as degreasing agents is comparable to that of NPE. 

Carbon tetrachloride and trichlorethylenc (found in degreasing agents and dry cleaning fluids). 

Non-ionic, e.g. certain esters made from oil (used as degreasing agents in industry). 

From the anionic surfactants (Table 1.1) the most relevant is LAS with an annual global production volume of more than 3 X 1061 in 2001. LAS has a wide application because of its excellent detersive properties and cost-performance ratio. Commercial LAS is applied mainly in the formulation of powder and liquid laundry detergents. The calcium salts are used as an emulsifier in pesticide formulations their amine salts are used in dry cleaning and as degreasing agents in the metal industry [14]. 

Uses Preparation of 3,4-dichloroaniline solvent for a wide variety of organic compounds and for oxides of nonferrous metals solvent carrier in products of toluene diisocyanate intermediate for dyes fumigant insecticide for termites degreasing hides and wool metal polishes degreasing agent for metals, wood, and leather industrial air control disinfectant heat transfer medium. 

Chlorinated ethanes and ethylenes comprise ethyl chloride, ethylene dichloride (1,2 dichloroethane), vinyl chloride, trichloroethylene (TCE), perchloroethylene (RCE), and several CFCs. Some of the major uses of these compounds are as degreasing agents, dry-cleaning solvents, building blocks for manufacturing of polymers (e.g., RVC, ethyl cellulose), and raw material for the production of tetraethyl lead and CECs. We discuss ethylene dichloride, trichloroethylene, and perchloroethylene as examples of this group. 

Methyl ethyl ketone Common solvent used in the manufacture of coatings, solvents, degreasing agents, lacquers, resins and smokeless powders. 

The toxic pollutants present in raw wastewaters from tire and inner tube manufacturing operations are volatile organic pollutants that are used as degreasing agents in tire production. These toxic pollutants (methylene chloride, toluene, trichloroethylene) were found to be reduced to insignihcant levels across sedimentation ponds. 

Workers in a ball-bearing manufacturing plant in Taiwan had severe dermatitis as a result of exposure to kerosene that was used as a degreasing agent. Eczema and erythema were also prevalent among the workers (Jee et al. 1985). 

According to Product Services Company, treatment will be most efficient at temperatures between 40 and 120°E. Pesticides, degreasing agents, and heavy metals may have an adverse impact on the microbial action. The pH should be between 4.5 and 9.5, with an optimum of 7.0. Moisture content should be maintained at 30% throughout the remediation. 

In this section we will present considerations that can be used to evaluate the environmental compatibility of solvents. The considerations are based on the Aberdeen/Green Seal Standard for Certification of Cleaning/Degreasing Agents for Steel and Alnmi-num, which was promulgated in the spring of 1999. While the standard is applicable to the cleaning industry, it rivets our attention to appropriate areas in which to evalnate solvents and solvent use.
