Abstract

<p>Cationic surfactants are generally used as softening agents in textile industry, hair conditioning agents in hair conditioner, antistatic agents, and antifungal agents. In addition, it is well known that cationic surfactants are used for organically denaturing clays such as montmorillonite and enhance the cooling effect by menthol. However, they are not safe for human skin so much in general and that limits the range of application. Accordingly, we focused on distearyl dimethyl ammonium chloride (DSAC) which is one of cationic surfactants and is thought to have relatively high safety. And we expected that the practical use of them is widely extended if we can obtain fine emulsions emulsified with DSAC. As a result, we have succeeded in obtaining fine emulsions (d. ~30 nm) by using polyoxyethylene/polyoxypropylene dimethyl ether (EPDME) as an auxiliary emulsifying agent.</p>
