SURFACE TENSION EFFECTS
There are several methods for determining the surface tension effects of wetting agents. We have included the more common ones: DuNuoy Tensiometer and Draves Method.
- DU NUOY TENSIOMETER

STABILITY TO METALLIC IONS

-
Many industrial applications involve the use of soluble metallic salts, and it is important that a wetting agent be stable to them, i.e., retain wetting action without forming insoluble salts or form ing complexes with surface tension reducing properties. In certain other operations, it is desirable that an insoluble salt be formed.

APPLICATIONS
EMBALMING
0.5$ Areskap 50 added to concentrated embalming fluids makes It possible for these solutions to permeate the body completely. By reducing the surface tension of the embalming liquids, they readily flow into even the smallest capillaries. So effective is the dis persion of color through the use of "Areskap 50," that a healthier glow than enjoyed in life is attained.
Embalming fluids are generally formulated with alcohol, glycerine and formaldehyde as the chief constituents. The following typifies such a product to which is added Areskap 50, as follows:

Summer oil sprays
An oil emulsion prepared at the New Jersey Experiment Station, Mew Brunswick, New Jersey, 3ald to be as good as can be prepared with any other emulsifier, consists of the following:
' Summer oil
Water Aresklene 400
66%
33.5% 0*5%
The dry Aresklene is dissolved in water. While this is circulated with a pump, the oil is added slowly with constant agitation with pumping. After all the oil has been added, the pumping is contin ued for about 10 to 15 minutes, then passed through a colloid mill
The customary oil emulsions, as manufactured by Government formula, consist of 2 gallons of oil, one gallon of water and one pound of
40% potash fish oil soap, the latter as an emulsifier. This gives an emulsiflable oil, containing 66% active unsulfonated oil. Re cently the Standard Oil Company of Indiana have begun to market an oil containing practically no water, 96% unsulfonated oil and 5% of oil-soluble emulsifying agent. These oils are diluted -at the point of application to yield a concentration of approximately 2% oil in a water emulsion. This latter being applied as a spray to trees.
For dormant or winter sprays, an oil having a viscosity of 150-200 Saybolt Seconds is employed; whereas, for summer sprays, an oil having a viscosity of 75-100 Saybolt Seconds is employed. The winter
oil sells for 25^ per gallon and the summer oil for 50^ per gallon.
Home-made Oil Emulsions for Summer Spraying in Apple Orchards
Joseph M. Ginsburgh, New Jersey Agricultural Experiment Station, New Brunswick, New Jersey, states that based on experiments conducted for
several years with various petroleum oil distillates, and with dif ferent emulsifying agents, a formula has been developed by which the
farmer can readily prepare a stable home-made oil emulsion for summer spraying in apple orchards, resulting in a large financial saving, A semi-refined paraffin distillate of the following specifications
proved equally as safe as the highly refined oil heretofore used and is, of course, considerably cheaper:
Bolling Range--Initial Pinal
A.P.I. Gr. Viscosity--Saybolt U./100 V.I. U.S.R.
570-590P 750-750P 31 or higher
65-75 90-100 or higher 82-84%
Of the many emulsifiers tested, sodium lauryl sulfate was found very effective. It produces a stable emulsion, compatible practically
with all kinds 'of water available on the farm for spraying purposes.
The stock emulsion consists of 70% oil, 29% water, and about 0.5 to 1.0% emulsifier.
-6- 016660?
TOWOLDMONOQ24557
The following procedure was found satisfactory with the ordinary
power sprayer. The emulsifier is first added to 10-20 gallons of water and transferred to the spray tank, containing the rest of the water. With the agitators and pump running at a pressure of 50 lbs. or higher, the oil is slowly run in. After all the oil has been added, mixing is continued for about 30 minutes or until the emulsion becomes thick, creamy and homogeneous, showing no free oil on the
surface. The finished emulsion is pumped into clean drums for stor ing. If foaming becomes excessive, reaching top of tank, about 1 to
4 pints of defoamer (3 lbs. of wool grease in one gallon of kerosene) may be added.
For spraying,the home-made emulsion is diluted with water to the
desired oil concentration in the same way as the commercial oil emul sion.
Pea Aphids
Rapid strides have been made during the past in solving the problem of the control of pea aphids. Canners and growers have a choice of several controls, embodying the use of derrl3 and cube in spray and dust form, nicotine in vaporized and dust applications,, and quite possibly combinations of these methods. It is a question now of a
choice of method rather than a search for suitable insecticide. '
One point stands out as being vitally Important in both dust and spray applications and that is the necessity, economy and advantage of using a satisfactory wetting and spreading agent.
An excellent material for this purpose is Dry Aresket 300 and the
solution form of this product, Aresket 240.
In dust applications containing derris, cube or nicotine, from 3 to 5 pounds of Dry Aresket 300 is used. This provides satisfactory sticking properties to the dust application and at the same time o r breaking down the surface tension of the moisture, promotes wider and more even spread of the insecticide.
In spray applications a pint of Aresket 240 to 100 gallons of spray
is generally used. This addition to the spray greatly increases the
effectiveness of the insecticide and makes the treatment more econom
ical.
Aresket is variously mentioned throughout the literature as Diphenyl Butyl Bodlua Sulfonate, Sulfonated Phenylphenol, Sulfonated Alkylated Diphenyl, and' others. It can be used in any kind of water and there is no record of its ever causing Injury to plants.
According to the JOURNAL OF ECONOMIC ENTOMOLOGY 28, P. 224, J. M. Olnsburg of the New Jersey Agricultural Experiment Station, New
Brunswick, New Jersey, outlines the use of wetting agents for oil insecticides

Ant Control
The University of Idaho, Department of Entomology, recommends a stock solution to be diluted as follows:
Carbon Bisulfide Crude Naphthalene Aresklene 400 Water
li gallons 56 ounces l ounces 2 quarts
-8-
TOWOLDMONOQ24559
Preparation of stock material: Dissolve the crude naphthalene in the carbon bisulfide. All lumps
must be broken up and the material completely dissolved. The mix ing can be done with electrically driven equipment or a small cream churn.
Place ther water and Aresklene together and agitate in the mixing apparatus until it has the appearance of very foamy soapsuds. Slowly add the carbon bisulfide - crude naphthalene solution to the water - Aresklene, agitating vigorously while adding. Continue the agitation for several minutes after all the materials are com bined. This completes preparation of the stock material.
Use of the material: The stock emulsion, prepared as described above, is diluted 1 part to 80 parts of water
(l/2 pt. emulsion to 5 gals, of water). The ant colony is prepared for treatment by building a dike of dirt about 2 Inches high around the outside, The area enclosed by the dike can then be filled once or twice with the diluted emulsion until enough is added to soak thoroughly through the colony. The amount of diluted material will vary between 5 and 10 gallons, depending upon the size of the colony. All stages of the ants are killed. The best time to treat is at dusk when the ants have all returned to the colony.
Wire Pickling
Using 0,75# Areskap 100 in a 15# HC1 bath (not 15# of l8Be Muria tic) based on the diluted weight of bath. Contact time of 9 seconds in a 20-ft. tank with very good results. Without Areskap it does not work.
Areskap 50 in Muriatic Acid pickling bath for wire has the following advantages:
1. Reduces the loss of Muriatic Acid through dragout,
2. Reduces the formation of dross in their galvanizing pot. Under their present process any iron salts which adhere to the work are carried into the gal vanizing pot and combine with zinc to form dross. . Better drainage of the work should aid in eliminat ing this.
3. Secure better pickling thru quicker penetration of the acid to the center of the colls.
