Abstract
Water-soluble polymer comes to be used for O/W type cosmetics from a viewpoint of skin irritation, feeling and long-lasting effect. A development of a polymer emulsifier also came to be performed in recent years. The emulsion stabilizing ability of polymer is derived from not only interfacial stabilization but also the structure modification of continuous phase. Therefore, rheological measurements of aqueous solutions of polymer and emulsions were performed, and the emulsification mechanisms were considered. Rheological properties of an emulsion using polymer thickener are dominated by properties of aqueous solution of the polymer. Polymers forming solid state at static state are preferable for the forma-tion of O/W type emulsions.
期刊介绍：
For the communication among the members, the journal of the Society of Rheology Japan, NIHON REOROJI GAKKAISHI (5 issues per year), was established in 1973 and it is the oldest journal on rheology in Asia. The journal contains original and review articles on rheology and related topics, information for all SRJ events, and reports of domestic/overseas meetings. Articles in Japanese as well as in English are considered for publication, not only from the members but also from the researchers outside. Papers from new emerging areas of the field are particularly welcome. The electronic version of the articles is available via the internet with an open access policy.
