Abstract: (A) A clad powdery or granular preparation of a medicinally active ingredient and (B) a powdery or granular ion exchanger such as a cation exchange resin are blended to prepare a solid preparation. The active ingredient includes .beta.-lactam antibiotics having a basic group. The clad powdery or granular preparation includes not only coated preparation wherein the active ingredient or preparation is coated but also a variety of preparations in which the contact of the active ingredient with the ion exchanger is suppressed or inhibited. Polymers such as a water-soluble polymer, an enteric polymer and so on can be used as the coating agent for the coated preparation. The using amount of the ion exchanger is about 10 to 5,000 parts by weight per 100 parts by weight of the active ingredient. Said solid preparation can remarkably decrease the unpleasant taste and odor of the active ingredient such as bitterness, being excellent in dissolution property and absorbability of the active ingredient.

Abstract: Alumina hydrate particles have a high surface area and low dispersity and may have a low soluble soda content. They may be made by milling a liquid suspension of alumina hydrate, subjecting the milled suspension to classification into coarse and fine fractions, recycling the coarse fraction to the mill and recycling the fine fraction to the classification stage. A narrow particle size distribution is obtained.

Abstract: A smooth, greaseless skin ointment especially prepared for irritated skin, which protects, adheres and simultaneously is easily washable without causing skin damage. The ointment base is a blend of polyethylene glycols. It is combined with a bioadhesive which works synergistically to allow the blended ointment base to adhere to wet and moist areas, while not being so adhesive as to cause damage when removed in washing. Specifically a blend of polyethylene glycol polymers is prepared to provide good skin feel and drag, a polyvinyl ether anhydride salt bioadhesive is added and a polyvinylpyrrolidone is also used as a dispersant, and feces and urine toxicant binder. Optionally minor amounts of dimethicone can be added.

Abstract: Process for preparing anion exchange resins comprising polymerizing a vinyl aromatic compound having at least one alkyl group containing about 1 to 3 carbon atoms, alone or mixed with a copolymerizable monomer, optionally in the presence of a mineral support, followed by brominating the alkyl groups of the resulting polymer by means of an N-bromoamide or an N-bromoimide, and then aminating the brominated product obtained. The resulting anion exchange resins are useful in the chemical, pharamaceutical, food, and metallurgical industries.
