Ethylene Propylene (EP, EPDM) is an o-ring rubber compound that is compatible with most water-based chemicals. It is good with caustic soda, detergents, water treatment chemicals, steam, and wastewater and with food processes like milk, beer, and soups. EP rubber compound is petroleum based and for this reason it should never come into contact with petroleum based chemicals. 

In this section, chemical resistance will be divided into three parts, viz. acid, alkali (including detergents) and water (including atmosphere). Normally an enamel is formulated to withstand one of the corrosive agents more specifically than another, although vitreous enamel as a general finish has good all round resistance, with a few exceptions such as hydrofluoric acid and fused or hot concentrated solutions of caustic soda or potash. 

The removal of organics by industrial detergent cleaners. These products employ several mechanisms, depending on the formulation, but tend to include dissolution (using nonaqueous solvents such as kerosene, petroleum spirits, and naphtha, saponification, by caustic, or emulsification by nonionic detergents. 

Usually, any two of these materials are combined to provide the required degree of causticity, general detergency, and de-oiling abaility a nonionic wetting agent and perhaps an antifoam may be added. 

One of the most important contracts in caustic soda is the contract for the alumina industry in Australia. This is just over one million tons out of world production of about 44 million. Some have questioned why this contract should have an influence on the markets elsewhere. Although the Australian demand is a fraction of world demand the alumina price there is adopted elsewhere, notably in the USA in the pulp sector and detergent sector. Thus a considerable part of the user industry is indirectly following events in Australia. In the past Australia has bought caustic soda from... 

Nonionic surfactants, as mentioned previously, have been widely adopted due to their characteristics and properties and, in particular, because they do not require the presence of undesirable phosphate or caustic builders in detergent formulation. However, the relatively lesser degree of biodegradability is an important disadvantage of the nonionic surfactants compared to the ionic ones. Adsorption on activated carbon and various types of clay particles is, therefore, one of the processes that has been effective in removing heterodisperse nonionic... 

Thus -alkanes (C10-C14) separated from the kerosene fraction of petroleum (by urea complexation or absorption with molecular sieves) are now used as one source of the alkyl group. Chlorination takes place anywhere along the chain at any secondary carbon. Friedel-Crafts alkylation followed by sulfonation and caustic treatment gives a more linear alkylbenzenesulfonate (LAS) which is soft or biodegradable. The chlorination process is now the source of about 40% of the alkyl group used for the manufacture of LAS detergent. 

Sodium hydroxide is the most widely used strong base in the chemical industry. It exists as a white, odorless, crystalline solid at room temperature. Sodium hydroxide is a highly corrosive and toxic substance and is called caustic soda or lye. Sodium hydroxide is used as an alkali in the production of numerous products including detergents, paper, synthetic fabrics, cosmetics, and pharmaceuticals. It is the ingredient in many common cleaners, degreasers, drain cleaners, and personal care products. 

Pollutants from point sources domestic sewage (detergents), industrial effluents (synthetic organics, metal cyanides, metals, caustic chemicals), landfill waste disposal (metallic ions, chloride, nitrate, nitrite, sulfate, and synthetic organics).
