  • Antiperspirant material and compositions containing it
    Patent number: 6245324
    Abstract: A particulate antiperspirant active material which has been surface treated with an alkanolamine is described. After surface treatment, the surface treatment agent is in intimate contact with the surface or outer layer of the substrate material, that is, the antiperspirant material may be either deposited on the surface or at least a fraction of the agent may be absorbed within the outer layer of the substrate. The resultant particulate material shows a reduced tendency to separate from a liquid carrier phase containing a polyglycol ether and a suspending agent.
