PROBLEM TO BE SOLVED: To provide an aqueous dispersion composition which prevents the decreased water resistance of a formed coating caused by adding a dispersion stabilizer, such as a surfactant, and is excellent in dispersibility and dispersion stability to provide cosmetics, coatings, and inks containing the same and particularly when using the aqueous dispersion composition for cosmetics, to provide cosmetics excellent in water retention ability, adhesiveness, antiviral activity, anti-oxidant action, a feel, and a feeling of use.SOLUTION: An aqueous dispersion composition contains (a) Aphanothece sacrum polysaccharide derived from Aphanothece sacrum which is freshwater cyanobacteria, and (b) pigment powders. Objective cosmetics, coatings, and inks are obtained by compounding the aqueous dispersion composition.SELECTED DRAWING: NoneCOPYRIGHT: (C)2016,JPO&INPIT【課題】界面活性剤などの分散安定剤の添加によって引き起こされる形成皮膜の耐水性の低下を防ぎ、かつ、分散性、分散安定性に優れた水性分散体組成物及びそれを含有する化粧料、塗料、インクを提供することを目的とし、特に該水性分散体組成物を化粧料に用いる場合は、水分保持能、密着性、抗ウイルス活性、抗酸化作用、感触、使用感に優れる化粧料を提供する。【解決手段】水性分散体組成物は、(a)淡水性藍藻類であるスイゼンジノリを由来とするスイゼンジノリ多糖体及び(b)顔料粉体を含有してなるものとする。該水性分散体組成物を配合することで目的とする化粧料、塗料、インクを得る。【選択図】なし
