An antiperspirant composition comprising

• (a) about 25% to about 55% cyclopentasiloxane;
• (b) about 5 to about 35% of non-volatile liquid emollients selected from octyl isononanoate, PEG-8 distearate, PPG-14 butyl ether, and phenyltrimethicone;
• (c) about 0.5% to about 15% of isostearyl behenate;
• (d) about 5% to about 20% of a mixture of hydrogenated castor oil and stearyl alcohol;

• (a) from about 25% to about 55% of a volatile material;
• (b) from about 5% to about 35% of non-volatile liquid emollient(s);
• (c) from about 0.5% to about 15% of non-liquid organic ester emollient(s) having melting point(s) between about 25° C. to about 60° C.;
• (d) from about 5% to about 20% of organic wax base(s) having low melting point(s) or high melting point(s) or mixtures thereof;
• (e) from about 0.05% to about 5% of low molecular weight polyethylene homo- or co-polymer;
• and
• (f) from about 15% to about 30% of a particulate antiperspirant active agent;
• comprising
• mixing, in any order, components (a) through (e) to form a mixture;
• heating said mixture until all of said components (a) through (e) are in liquid form;
• adding component (f) to said mixture in liquid form;
• allowing the mixture to cool and filling the mixture into containers.
