An upper limit of oil content is limited to about ______________ percent for achieving efficient and satisfactory level of wax sweating?
Correct answer: C. 40
- A. 5
- B. 15
- C. 40
- D. 60
Explanation
Wax sweating works best when the oil content is not excessive, because retained oil interferes with separation during controlled heating. An oil content of about 40 percent is the stated upper limit for efficient sweating.
