Abstract: An antiperspirant composition containing an astringent compound, a volatile carrier, and a suspending agent for the astringent compound. The improvement relates to incorporating into the composition as the suspending agent a hydrophobic macroporous highly crosslinked polymer. The hydrophobic macroporous polymer is free of "in situ" entrapped active ingredients. The preferred antiperspirant product is a roll-on formulation.

Abstract: An antiperspirant stick product containing as components at least one material such as astringent antiperspirant compounds, a volatile silicone, a waxy material, emollients, perfumes, coloring agents, and other ingredients normally used in making stick products. The improvement is directed to incorporating into the stick product as one component a macroporous highly crosslinked polymer. The macroporous polymer is free of "in situ" entrapped active ingredients.

Abstract: A composition which is includes discrete particles of a highly cross-linked macroporous hydrophobic polymer. The particles are of a first predetermined average diameter, and the polymer particles have entrapped therein and dispersed uniformly throughout an active ingredient. The composition also includes a coacervating agent mixed with the polymer particles in an amount sufficient to cause the polymer particles to collect forming dense clusters of coacervated particles of a second predetermined average diameter, the second predetermined average diameter being substantially in excess of the first predetermined average diameter.
