ABSTRACT:
To provide a dental alginate impression material composition capable of solving a problem that the permeation rate of water with respect to the whole powder of an alginate impression material is slow at the time of use so that a kneading time is long and a sufficient operational time cannot be secured, and a problem that a kneaded material drops into a throat due to aging of the material at the time of taking an impression, the dental alginate impression material composition comprises 0.001 to 1% by weight of one or more kinds selected from oils mainly consisting of a fatty acid and an ester of alcohol, waxes mainly consisting of a fatty acid and an ester of glycerin, and a fatty acid ester; 0.01 to 10% by weight of a surfactant; and 0.01 to 10% by weight of one or more kinds of specific polysaccharides.
