Document Type and Number:
Japanese Patent JP3070696
Kind Code:
B2
Abstract:
PURPOSE:To provide the subject composition exhibiting a sufficient antibacterial action without causing the deterioration of the quality and the lowering of the physical properties by the absorption of moisture by compounding a slightly water-soluble antibacterial agent, a hydroxy compound and a surfactant. CONSTITUTION:A hydrocolloid impression composition for dentistry is characterized by compounding a slightly water-soluble antibacterial agent such as cocoyl alginate or 2,4,4'-trichloro-2'-hydroxy-diphenyl ether, a hydroxy compound such as polyethylene glycol, glycerol or hydroxypropyl cellulose preferably in an amount of >=0.5wt.% and further a surfactant (either of anionic, cationic, amphoteric and nonionic surfactants) preferably in an amount of approximately 0.005-5.0wt.%. The composition can be uniformly coated on the surface of an impression material without relating to the shape of the slightly water-soluble antibacterial agent, such as a powdery or oily shape, and gives the impression material having a smooth surface without absorbing moisture and a sufficient antibacterial property. The composition does not substantially generate dust and is readily handled.
