Abstract: Disclosed are topical leave-on compositions such as antiperspirant and deodorant compositions comprising (b) from about 0.01% to about 10% by weight of selected pantothenic acid derivatives, (b) from about 10% to about 99.89% by weight of a liquid carrier, wherein the composition has a pH of from about 2.0 to about 5.0, or otherwise comprises an acidic skin active agent or other similar material such as an aluminum-containing antiperspirant active. The selected pantothenic acid derivatives remain stable within the antiperspirant or acidic compositions and provide improved skin feel and cosmetics benefits.

Abstract: Disclosed are anhydrous antiperspirant and deodorant compositions comprising from about 0.1% to about 30% by weight of an underarm active (antiperspirant and/or deodorant active); from about 0.01% to about 10% by weight of a solid, encapsulated, water-soluble, d-pantothenate salt such as calcium pantothenate; from about 0.1% to about 40% by weight of a suspending agent; and from about 10% to about 99% by weight of an anhydrous carrier liquid. Also disclosed are methods of controlling perspiration wetness and/or odor through the topical application to the underarm, especially shaven underarms, of an underarm active and a solid pantothenate salt. The anhydrous compositions are mild to the skin and can help sooth or heal skin irritated or damaged underarm skin, especially when such irritation and damage is the result of occasional or routine shaving of the underarmn.

Abstract: Disclosed are pressurized antiperspirant compositions comprising (a) a polyol solvent having at least 4 carbon atoms and a hydroxyl group on each of the &agr; and &bgr; carbon atoms of the polyol solvent; (b) solubilized antiperspirant active; (c) dimethylether; (d) a low polarity liquid having a solubility parameter of less than about 8.0, wherein the weight ratio of the dimethylether to low polarity solvent is from about 0.1 to about 2.8. It has been found that these compositions are especially useful in formulating clear or single-phase pressurized antiperspirant compositions that remain stable over prolonged periods and that can be formulated without ethanol or aqueous solvents.

Abstract: An applicator assembly for applying liquid product to the hair. The applicator assembly has an applicator that further base and multiple tines extending from the base. Opposite the tines, the base has a liquid distribution cavity. At least some of the tines have a tip at the end opposite the base, and may also have an enlarged fin section adjacent to the base. The enlarged fin sections extends to a shoulder portion located less than half way upward between the base and the tip of the tine. The tines may also have an aperature that allows fluid to be distributed from the cavity directly to the hair. The tip of the tine may be relatively flexible, while its enlarged fin section provides a more rigid lower portion.

Abstract: A method for controlling an amount of material delivered during a material transfer. This method includes the steps of inputting a target amount for a material to be delivered from a source location to a target location, updating the target amount during the delivery of the material using a predictive model-based algorithm, and updating the predictive model-based algorithm based on process performance data using a recursive least-squares procedure. An adaptive selection algorithm which is used to determine whether at least one previous predictive model-based algorithm parameter should be replaced with at least one new predictive model-based algorithm parameter in order to adapt the predictive model-based algorithm in response to a process change. A method for overlapping a delivery of at least one independently measured material with a delivery of a main material during a material transfer process.

Abstract: The present invention provides an applicator for applying and distributing a substance onto a target surface. The applicator comprises a substantially planar sheet of compressible, conformable material having opposed first and second surfaces and an interior region between said first and second surfaces. The applicator further includes at least one discrete reservoir underneath the first surface which is at least partially filled with a substance and at least one discrete aperture formed in the first surface which is in fluid communication with the reservoir. Compression of the applicator via an externally-applied force substantially normal to said first surface expresses product from the aperture and translational motion of the first surface relative to a target surface applies, and distributes said product onto the target surface. In one embodiment, an applicator provides a removable cover sheet which aids in the containment of the substance.

Abstract: A delivery system comprising a first container (24) in which a first material is to be held; a second container (66) in which a second material is to be held, the second container being capable of being put into fluid communication with the first container to enable the second material to be added to the first material to form a flowable composition in the first container, and user-actuable means (72) for mechanically generating a pressure differential to allow all of the flowable composition which is discharged to be discharged from the first container (24) at any orientation.

Abstract: An applicator for applying and distributing a substance onto a target surface. The applicator comprises a substantially planar sheet of compressible, conformable material having opposed first and second surfaces and an interior region between the first and second surfaces. The sheet of material has a thickness between the first and second surfaces which decreases when the sheet of material is subjected to an externally-applied force in a direction substantially normal to the first surface. The applicator further includes at least one discrete reservoir extending inwardly of the first surface into the interior of the sheet of material which is at least partially filled with a substance and at least one discrete aperture formed in the first surface which is in fluid communication with the reservoir.

Abstract: A disposable catridge for use with an electrostatic charging device. The disposable cartridge can have a reservoir configured to contain a supply of product suitable for electrostatic spraying, a nozzle configured and disposed to disperse the electrostatically charged product, and an electrode disposed to electrostatically charge the product prior to its dispersal. The disposable cartridge can also have an insulator for insulating the supply of product from electrostatic charge.
