  • the cleaning composition has soil loading capacity of at least 15 weignt percent at 60°C.
  • This soil loading capacity is the weight percent of soil , i.e. grease or oii, wmcn when present in the cleaning composition causes the cleaning performance of the formuiation to decrease below 90 percent.
  • Aprocedure foUowec to measure soil loading capacity is to soil a series of 2" x 1/2" x 1/16" 1010 steel coupons with grease or oil (soil) . The oil is applied by dipping the coupons in the oil, and then allowing the excess oil drip off before weighing the coupons. These coupons are placed in 1 -ounce bottles containing solutions of the ⁇ eaner containing various weight percentages of grease or oil, i. e. soil loading.

  • the ability to separate from water is determined bymixing, at room temperature, thirty ml of the cleaning composition and 70 mi of deionize ⁇ water in a graduated cylinder. Location of the initial meniscus is noted and the cylinder is inverted several times to insure mixing The cylinder's left undisturbed for a set period of time then the appearance of each layer and the location of the meniscus are noted. The same tests are repeated at 6C°C.

  • the 1010 steel coupons were greased as described in Example 1 with Prestige 74' Lithium Grease and placed in 1-ounce flint bottles containing 15 ml of an emulsion made by mixing 4.5 ml of the formulation with 10.5 mi deionized water (30/70 ratio).
  • Each formulation contained dipropylene glycol n-butyl ether (DPnB), a C,. _.. linear hydrocarbon and the various surfactants shown in the amounts listed in Table 2
  • the bottles were placed in an Eberpach snakerand shaken at 180 oscillations per minute. The shaker was stopped every 1 minute so that the coupons could be visually inspected for cleanliness. The test was discontinued when grease could no longer be seen on the coupon.
  • Each formulation was tested in tripilcate and the results averaged.
  • Example 3 The procedure in Example 3 was followed with the exception that the test composition was varied as shown in Table 3 below
  • the coupons were greased as described previously with each of the commercial greases and placed in 1-ounce flint bottles containing 20 ml of an emulsion made by mixing 6 ml of heat solvent or formulation with 14 ml delonized water (30/70 ratio)
