A process for forming a free standing antiperspirant or deodorant solid stick product using particulate and fluid materials that are combined by means of amalgamation, homogenization, compaction and extrusion at a temperature below the melting temperature of said product and extruded by mechanically working the particulate and fluid materials.

Extruded stick product and method for making same

A low residue antiperspirant and/or deodorant composition in the form of an anhydrous, surfactant-free and antiseptic alcohol-free suspension exhibiting a syneresis of less than 8% which is made by combining selected amounts of: (a) a cyclomethicone (and) dimethicone crosspolymer made with an &#x2261;Si&#x2014;H containing polysiloxane and an alpha, omega-diene of formula CH&#x2550;CH(CH)CH&#x2550;CHwhich crosspolymer has a viscosity in the range of 50,000&#x2013;3,000,000 centipoise, preferably with a nonvolatiles content of 10&#x2013;14% in cyclomethicone; (b) polyethylene beads having a density in the range of 0.91&#x2013;0.98 grams/cmand a particle size in the range of 5&#x2013;40 microns; (c) a volatile silicone; (d) an emollient (or a mixture of two or more emollients) which may include a non-volatile silicone and an additional amount of a volatile silicone; and (e) an effective amount of an antiperspirant active material in an amount sufficient to have an antiperspirant and/or a deodorant effect.

Effective soft solid personal care product

A low residue antiperspirant and/or deodorant composition in the form of an anhydrous, surfactant-free and antiseptic alcohol-free suspension exhibiting a syneresis of less than 8% is disclosed which comprises: (a) a dimethicone/vinyldimethicone crosspolymer composition made by reacting a polymethylhydrogensiloxane with an alpha, omega-divinylpolydimethyl siloxane for which the dimethicone/vinyldimethicone crosspolymer composition is used at a concentration of 0.5&#x2013;10% in cyclomethicone; (b) polyethylene beads having a density in the range of 0.91&#x2013;0.98 grams/cmand a particle size in the range of 5&#x2013;40 microns, wherein the polyethylene beads are used in an amount of at least 2% by weight based on the total weight of the composition; (c) a volatile silicone; (d) an emollient or mixture of two or more emollients; and (e) an effective amount of an antiperspirant active material.

Stable and efficacious soft solid product
