Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
98 words
A paste-like polishing composition for stainless steels and the like consisting essentially of water, alumina powder, an aliphatic monohydric alcohol having from 12 to 20 carbon atoms and a waxy condensation product of ethylene oxide and of an aliphatic monohydric alcohol having from 12 to 20 carbon atoms; said alumina powder constituting from about 40 to 50 parts, said aliphatic alcohol constituting from about 7 to 20 parts, said polyoxyethylated alcohol constituting from about 7 to 10 parts, and said water constituting from 27 to 30 parts, all by volume per 100 parts by volume of said composition.
Claim 2
Dependent Claim
