• the particle size of the abrasive is less than 0.5 mm. and in general, the maximum particle size of substantially all of the abrasive is about 0.15 mm. Normally the abrasive employed will have a particle size such that at least about 85% and preferably 99% by Weight thereof passes through a sieve having 0.074

• alkyl aromatic sulfonate detergents are the propylated naphthalene sulfonates, the mixed butyl naphthalene sulfonates, tetrahydronaphthalene sulfonates, the various butylated diphenyl sulfonates and phenyl-phenol sulfonates.
