And when the pH of α-CB solution approaches to pI, the system presents the lower surface tension and cmc than other forms. Some applied performance of α-CB are examined and the experimental results suggest that α-CB exhibits good foaming performance, excellent lime soap dispersing ability and hard water-resistance capability. This study indicates that α-CB is a candidate for the efficient lime soap dispersant.
