Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>To improve the alkali and heat resistances of Cl+Me‐isothiazolinone (MCI/MI), a calcium alginate (CA) hydrogel sphere was used as the carrier for MCI/MI, and an MCI/MI/CA hydrogel sphere was prepared. Then, the release properties, alkali‐resistance and heat‐resistance properties, long‐term antibacterial performance, and cytotoxicity of this novel hydrogel sphere were investigated. The results show that the CA hydrogel sphere released MCI/MI in a sustained manner with long‐term antibacterial activity. Moreover, the CA hydrogel sphere improved the alkali and heat resistances of the MCI/MI. More importantly, this hydrogel sphere showed a slight cytotoxicity, which suggested that the MCI/MI/CA hydrogel sphere would be an easily added antibacterial hydrogel sphere for a wide range of products. © 2013 Wiley Periodicals, Inc.
