Introduction .
''
.
Solubility
The unique Aroclor*1 plasticizers are among the most versatile chemi cally produced materials available. One outstanding characteristic -- . inertness -- makes Aroclor useful in malty was* tor many different applications. The major benefits offered by Aroc >r include:
' Chemical Resistance -
Fire Retardance
. Compatibility v. illt most resins
Nonaxidation
Adhesivity
.
Low Cost
Monsanto's Aroclor plasticizers comprise a ser-s of chlorinated bi phenyls and chlorinated polyphenyls. They v;.-y from mobile, oily liquids to white crystals and hard, transparent rosins.
Twelve of the Aroclor plasticizers, each of which represents a series,
are discussed in this bulletin. An understanding of the system for
designation of each Aroclor should prove useful m the evaluation of the property gradations among them. The last two digits indicate the approximate weight frcrcentage of chlorine in the product, and the first
two digits indicate the type of material, as follows: .
12 -- chlorinated biphenyls
'
25 -- blend of cn'orinated biphenyls and . hlorinated triphcnyls (75:25)
44 -- blend of chlorinated biphenyls and ' hlorinated triphenyls
' (60:40)
54 -- chlorinated triphenyis
For nearly every Aroclor nv-ui ioned. a darker, icss-pure grade exists,'
with about"the su.,".r j,h.% steal ..r.d cl.envcai cha, acteristias, but lower
in ppce.
.
The Aroclor liquids and resins are readily soli hie in most common organic solvents and drying oils. Although all A"ocior plasticizers are - insoluble in water, ibara. Tystaiiine muter is are generally less soluble than the liquids and softer resins. Solub; ities of some Aroclor plasticizers arc shown in Table 1.

It is concluded that the vaporization rates of Aroclor plasticizers -- especially the most widely used 1254 and 1260 -- compare most favorably with the similar constants of other plasticizers selected specifically for these tests because of their low vaporization rates.

The viscosities of the Aroclor plasticizers vary according to whether the bo.se materia! is a biphenyl or a polyphenyl and on the degree of chlorination. In general the low-chlorinated biphenyls have the lowest viscosities (Figure 3).

TOWOLDMON0036004
forfeit/ Ar.j Safe Handling
hhththn
At ordinary temperatures the Aroclor chlorinated polyphenyls have not presented industrial toxicological problems. The hazard of potential toxic exposure varies with their volatility: the lower-chlorinated, more.volatile ones present more of a potential problem from the standpoint of both inhalation and skin contact. When Aroclor plasticizers are used at elevated temperatures, engineering controls must be applied, either by the use of closed systems or by affective local-exhaust ventilation together with general workroom exhaust.
Vapor of the liquid Aroclor plasticizers at room temperature should not bo breathed in a confined space, and no vapor of any Aroclor evolved at elevated temperatures should be allowed to be dispersed into the general workroom.
Inhalation teats on animals indicate that the maximum safe concen tration of vapor is in the range of from 0.5 to 1.0 milligram of the lower-chlorinated Aroclor piaaticizers per cubic meter of air. The threshold limit values (maximum allowable concentration for an 8hour working day) set by the American Conference of Government Hygienists are 1.0 milligram of the lower-chlorinated Aroclor com pounds per cubic meter of air and 0.5 milligram of the more-highlychlorinatcd compounds, such as Aroclor 1254, per cubic meter of air.
Skin Confect
''
Schwartz patch tests on 200 volunteers showed that Aroclor 1254 was neither a primary skin irritant or a sensitizer.
Prolonged or repeated skin contact with the Aroclor plasticizers must be avoided by the use of gloves and protective garments, because of the possible occurrence of a condition called chioracne. Although re ports of this condition caused by Aroclor are rare, it can be produced by excessive skin contact. If any Aroclor is spilled on the 3kin the skin should be-washed in the usual manner with a soap solution.
A burn caused by contact with a hot Aroclor should be treated like any ordinary burr. Aroclor plasticizer achering to the burned area need not be removed immediately, unless treatment of the bum demands it, in which case either soap and water or repeated washings with a vegetable oil are recommended.

[nvimmntal Hands
Aroclor 1232, Aroclor 1242, Aroclor 1248, Aroclor 1254, Aroclor 1260, Aroclor 1262, Arodor 1268, Arodor 4465, and Montar 1 all contain polychlorinated biphenyls (PCB) of various types and in varying amounts. PCB residues in small amounts have been found in the environment and some studies have indicated that they may be harmful to certain forms of animal life. Extreme care should therefore be taken by all users of PCB-containing products to prevent any entry into the environment through spills, leakage, use, disposal, vaporization or otherwise. Further,..the products in which PCB materials are used, or which are formulated using PCB materials as a component, should be given careful study to eliminate the possibility -that PCB might reach the environment as a result of use in a given application.
Some specific applications where the use of PCB should definitely be avoided arc in paints and sealants for swimming pools, paints and waterproofing agents in siios and other buildings where food products for humans or animals are stored, and as a component of any container or wrapping used in the packaging of food products.
