Abstract: The invention comprises a liquid composition which provides a drier feel and reduced leakage when used with certain types of applicators, especially an applicator having a porous surface, which composition is made by combining an active phase and a silicone phase. The active phase is made by combining: (a) 10-70% of a selected glycol; (b) 0.1-10% of a nonionic emulsifier having an HLB greater than 8; (c) 0.01-30% of a cosmetically active ingredient; and (d) 0-20% of ethanol and/or isopropanol. The silicone phase is made by combining: (a) from 0.1-10% of a selected emulsifier; (b) 0-30% of a non-volatile silicone; (c) 0-30% of a volatile silicone; and (d) 0-25% of an organic emollient; provided that: (a) the silicone phase contains at least 10% silicone; (b) the ratio of silicone phase to active phase is in the range of 1:1 to 1:4; and (c) the composition is processed to maintain a viscosity in the range of 2,000-200,000 centipoise ("cps").

Abstract: An invention is disclosed which comprises gelling agents which (1) contain both siloxane groups and hydrogen-bonding groups to thicken compositions containing silicone fluids (volatile and/or non-volatile silicone fluids); (2) are non-flowable solids at room temperature; and (3) dissolve in a fluid which contains silicone at a temperature of 25-250 degrees C to form a translucent or clear solution at a temperature in this range. Cosmetic compositions may be made by adding at least one active ingredient such as an antiperspirant.

Abstract: Disclosed are antiperspirant stick compositions that exhibit substantially no visible residue (whitening) upon application to the skin or after drying. The compositions include both emollients that are silicone materials and emollients that are not silicone materials, these materials having a refractive index of at least 1.4460, in addition to including a vehicle (for example, cyclomethicone), a gelling agent (for example, stearyl alcohol and hydrogenated castor oil) and the active antiperspirant material (for example, particulate antiperspirant metal salts). These compositions reduce the necessity of using expensive silicone materials, while still achieving antiperspirant compositions with substantially no visible residue.

Abstract: Described is a fragrancing composition having fragrancing components that are not activated until, e.g., application to the skin of a human. The composition is alkaline or (if anhydrous) capable of producing an alkaline pH when in contact with water, prior to application, and includes (1) a vehicle such that when the composition is in contact with water, prior to application, the composition is at an alkaline pH; and (2) at least one potential fragrance that is at least one compound having little or no odor in the alkaline composition but which, e.g., is hydrolyzed in a lower pH environment to produce compounds having a relatively strong aroma. Upon application of the alkaline composition to the skin surface, the strong buffering capacity of the skin (the surface of which has a normal pH of 5.5-7.0) neutralizes alkalinity of the composition (lowers pH) so as to restore normal skin surface pH; the potential fragrance is then hydrolyzed at the lower pH to release the compound having relatively strong aroma.

Size exclusion high performance liquid chromatography chromatograms of the disclosed basic aluminum materials have a peak 4 relative area of at least 25%, a peak 3 relative area of less than 60%, the sum of the peaks 3 and 4 being at least 50%; and less than 10% of the chromatographic peaks eluting at peaks 1 and 2. The disclosed basic aluminum materials have less than 25% of the aluminum in the form of Al.sup.b polyhydroxyaquoaluminum, and have a .sup.27 Al NMR spectrum in which the area of the 71.5-73.5 ppm resonance line includes more than 50% of the combined areas of the 62.5-63.5 ppm and 71.5-73.

Abstract: Disclosed is a gel or stick composition for reduction of body malodor, containing active deodorant and/or antiperspirant ingredients, a polyamide gelling agent and a solvent system for the polyamide gelling agent. The polyamide gelling agent has good stability, even in the presence of acidic antiperspirant metal salts, and can provide a clear deodorant or antiperspirant gel or stick. The composition has good pay-off characteristics and application properties, and good structural integrity. Moreover, the composition can be formulated so as not to leave any undesirable residue, such as a white residue left after applying conventional antiperspirant sticks.

Abstract: Disclosed is a clear, crystal-free, soap-gelled cosmetic stick composition. The composition includes a soap gelling agent (e.g., sodium stearate); at least two aliphatic polyhydric alcohols that are solvents for the soap gelling agent and that have a relatively small molecular weight and a relatively large molecular weight (e.g., propylene glycol and dipropylene glycol), respectively; a propoxylated ether that is a further solvent for the soap gelling agent, such as a propoxylated butyl ether (e.g., PPG-14 butyl ether); water; and a clarifying agent. The clarifying agent is a mixture of (a) a propoxylated fatty alcohol, such as a propoxylated myristyl ether (e.g., PPG-3 myristyl ether), and (b) a water-soluble, N-substituted aliphatic fatty acid amide surfactant (e.g., a combination of cocamide DEA and cocoyl sarcosine). The stick composition has improved surface aesthetics and improved payout, and has less pullaway from the container.

Abstract: Disclosed is a fragrance composition having enhanced efficacy for masking malodor for extended periods of time, to be used in deodorant compositions. The fragrance composition includes materials providing fruity, aldehydic and green notes, in an olfactory effective amount, and also includes at least 10% (e.g., 10%-28%) by weight, of the total weight of the fragrance composition, of acetyl hexamethyl tetralin. The fragrance composition can be incorporated in a body deodorant (for example, a deodorant for axillary regions, such as a deodorant stick) to mask body malodor arising in, e.g., axillary regions.
