Seven chemistries were selected for testing. In addition to the chemistries, Acetone was used to give a baseline level to compare the alternatives to. The chemistries selected were:
Company
Tradename
Concentration
Brulin & Company
Compliance Blend

AW Chesterton
803
100%, 50%
MacDermid
ND-17

Easter Color
Eccobrite Cleaner AK

Terpene Technology
HTF 85B

The cleaners were applied to the sample using a saturated paper towel. The time and effort required to clean the contaminant were observed and noted. These two factors were then used to construct a table of cleaning effectiveness.

From the results obtained in the previous trial and from this trial, there were five possible alternatives for acetone. These cleaners were: Loctite 7360, Brulin Compliance 100%, Terpene Technology HTF 85B, Eastern Color & Chemical Company Eccobrite Cleaner AK and Isopropyl Alcohol. A table with more information on each cleaner was constructed to aid in the selection process.
It should also be noted that Isopropyl alcohol is flammable. In using IPA as a replacement, the current hazard may be eliminated; However, a different hazard comes into existence.
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Conclusion:
After trying several chemicals, five cleaners showed excellent removal of the contaminant. Additional information on these chemistries were provided to help aid the client in the selection of an appropriate substitution for Acetone.
