云母钛珠光颜料在洗发水体系中悬浮稳定性的研究

Study of suspension stability of mica titanium dioxide pearl pigment in hair shampoo system

为了提高云母钛珠光颜料在洗发水体系中的悬浮稳定性,采用5种表面改性剂对云母钛珠光颜料进行表面改性。实验结果表明,云母钛珠光颜料经正十八醇表面改性后其在基础洗发水体系中的悬浮分散稳定性得到有效改善。在适宜的改性条件下,改性后云母钛珠光颜料在基础洗发水体系中的初始沉降时间由改性前的0.2 h延长到2.2 h,完全沉降时间由6.0 h延长到46.5 h。

In order to improve the suspension stability of mica titanium dioxide pearl pigment in hair shampoo system ,five kinds of surface modifiers were used for the surface modification of mica titanium dioxide pearl pigment. Experimental results showed that octadecanol can effectively improve the suspension stability of mica titanium dioxide pearl pigment in hair shampoo base. In appropriate modification conditions, the initial settling time increased from 0.2 to 2.2 h, fully settling time increased from 6.0 to 46.5 h.
