Oil-absorbent composition, particulate oil absorber, oil-absorbent material, and oil-absorbent pack

A method for producing an absorbent, which comprises:

• mixing and dispersing 50 to 95 parts by weight of (1) an oil-absorbent, cross-linked polymer formed from 96-99.999% by weight of (A) a monomer having a polymerizable unsaturated group in the molecule, said monomer (A) containing mainly a monomer having a solubility parameter of not more than 9, and 4-0.001% by weight of (B) a cross-linking monomer having at least two polymerizable unsaturated groups in the molecule, provided the sum of monomer (A) and cross-linking monomer (B) is 100%, with 50 to 5 parts by weight of (IV) at least one compound selected from the group consisting of a multivalent salt of a fatty acid of 6-30 carbon atoms, said multivalent metal salt having a dissolving degree of not more than 1 gram per 100 grams at 20.degree. C. provided the sum of oil-absorbent, cross-linked polymer (I) and compound (IV) is 100 parts by weight in an aqueous medium;
• and then
• aggregating and granulating the resultant mixture to form a granular powder having an average particle diameter of 0.01-20 mm.
