To make a test of the new salt water soap developed for the Army say Louise Feldman left, and Frances Montgomery, chemists in the DuPont Technical Laboratory at Deepwater Point, New Jersey. Miss Montgomery, using the new soap khaki colored for camouflage, got the heavy fuel oil off her hand quicker and more easily that Miss Feldman who used ordinary soap. Secret of the new soap's success is a special synthetic detergent, know n only as MP-646, developed by DuPont chemists. Both the laboratory basins contain salt water, often the only kid available to soldiers for bathing and laundry in some theaters of war.
Viton' fluoroelastomer, DuPont's new fluorine-based elastomer is milled into sheets, the final step in its manufacture at the Deepwater Point, New Jersey plant. At this stage, it is a translucent, light colored gum which rubber companies compound with other ingredients to fabricate end products. 'Viton' has a super resistance to oils, fuels and solvents at high temperatures.
Synthetic detergent, left, produces billowy suds in hard water, while soap, right, forms insoluble curds. DuPont introduced the synthetics in America in 1933. Now the Organic Chemicals Department produces a number of synthetic detergents and other surface-action agents which find wide application in the textile industry.
The growing variety of handy aerosol bombs is displayed by an operator at the DuPont Company's Chambers Works in Deepwater Point, New Jersey. This man helps to make the Freon fluorinated hydrocarbons that propel various sprays. The bug bomb was acclaimed as one of the most useful new weapons of the last war. Using as a propellant the same fluid that keeps refrigerators cold, the hand bombs efficiently sprayed insect killing chemicals. Now the bombs are used to spray shampoo, shoe polish, paint and a host of other things in a veritable spray gun revolution.
Interview with Robert A. Shinn about the history of the Chambers Works property. Shinn describes the changes in the area that took place during World War I, when DuPont's workforce expanded. Also discussed are female factory workers, the beginning of the dyeworks, the relationship with General Motors, World War II, the Manhattan Project, company picnics, the Deepwater Plant, the plant hospital, Thomas Carney's ghost, employee benefits, the trolley line,
For the most part, textile fibers-natural and man made- have wide varying physical and chemical properties. The differences are apparent in the types of dye which adhere to the fibers. By mixing or blending fibers with different dyeing characteristics in the same fabric, the result is cross dyeing, each fiber picking up its particular dye in the bath or chamber and disregarding the others.
A Launderometer, a machine which tests the fastness of dyes in chemicals used in commercial laundries. Pieces of the dyed fabric are place din the jars with the chemicals and some stainless steel balls. The whole battery of jars is then revolved for the duration of the test.

Within the last few years, the chemist has developed a new kind of soap. Starting with ordinary vegetable and animal oils, the chemist now makes fatty alcohols which, in combination with sulfuric acid and other chemicals gives a new class of compounds known fatty alcohol sulfates. Although chemically quite different from ordinary soap certain of the fatty alcohol sulfates are the best detergents know. That is, they are similar to ordinary soap in cleansing properties but are better in that they work just as well in hard water as in soft water. Even with briny ocean water they form billows of foaming suds. Nor do they injure the most delicate fabric or tender skin. Because of their compatibility with hard water, these new soapless soaps are now finding wide application. This photographs shows a scene of what is known as a Gardinol flaker at the Deepwater Point New Jersey plant of E.I. du Pont Nemours & Company. The final step in manufacturing this synthetic detergent is processing through flaker rolls such as these.

Among its chief chemical products are dyes and intermediates, textiles and rubber chemicals, tetraethyl lead antiknock compound, petroleum chemicals, 'Freon' fluorinated hydrocarbons and organic isocyanates.
Chambers Works of DuPont's Organic Chemicals Department, one of the largest chemical and dyestuffs plant in the Western Hemisphere. Manufacturing facilities, together with three related research laboratories, occupy an area of about 600 acres at Deepwater Point, New Jersey. Plant employs approximately 6,000 people and manufactures dyestuffs, tetraethyl lead, fluorine compounds and other organic chemicals for the petroleum, textile, paper, refrigeration and other industries.
