An anhydrous skin treatment composition is provided which includes a crosslinked siloxane elastomer gel of specific yield point, a skin conditioning agent and a volatile siloxane. Inclusions of the select elastomers provide improved uniform distribution of the pigments.

Anhydrous cosmetic compositions

An apparatus is described for the coating of a human body with a tanning composition, such as a sunless tanning composition, wherein an arm with a plurality of nozzles thereon traverses within a booth to spray coat a body in the booth. The spray nozzles are oriented to avoid opposing air flows and excessive air flows which cause inefficient and uneven, dripping or streaking in the deposition of tanning composition on the skin. In another aspect, the apparatus provides for a foot rinser to rinse the feet of a user while the apparatus applies a sunless tanning composition to the user to avoid overly darkening the user's feet. In yet another aspect, the apparatus provides for a sanitation system to wash-down the spray booth between successive uses.

Apparatus for automatic application of compositions to the skin

Gel compositions are disclosed containing a silicone polyether elastomer from the reaction of an organohydrogensiloxane having at least two SiH containing cyclosiloxane rings in its molecule, a compound or mixture of compounds having at least two aliphatic unsaturated groups in its molecule, and a hydrosilylation catalyst The silicone polyether elastomer reaction product may itself be a gelled composition, or optionally may be contained in a carrier fluid to form a gel The gel compositions may further contain a personal or healthcare active

Silicone polyether elastomer gels

A non-volatile lubricious coating composition is provided for use with medical devices, such as hypodermic needles, catheters, and the like. The coating composition includes a first siloxane polymer having a very low viscosity less than about 50 centistokes, a second siloxane polymer having a high viscosity greater than about 1,000 centistokes, a reactive silicone polymer which is capable of crosslinking upon exposure to radiation, such as a UV curable silicone acrylate, and a photoinitiator to accelerate cross-linking of the reactive silicone polymer. The coating composition may further include an aminofunctional siloxane polymer to promote adhesion to metal surfaces when used with needles. The coating composition provides flowability without the need for any volatile organic solvent, and is capable of curing to provide adhesion and lubricity.

Non-volatile lubricant system for medical devices

Gel compositions containing a silicone elastomer from the reaction of an organohydrogensiloxane having at least two SiH containing cyclosiloxane rings in its molecule, a compound having at least two aliphatic unsaturated hydrocarbon groups in its molecule, and a hydrosilylation catalyst. The silicone elastomer reaction product may itself be a gelled composition, or optionally may be contained in a carrier fluid to form a gel. The gel compositions may further contain a personal or healthcare active. The actives may be incorporated into the gel via either a pre or post load method.

Silicone elastomer gels

A composition comprising the hydrosilylation addition product of a linear alkenyl functionalized polyorganosiloxane and an M H Q resin and a low molecular weight silicone when subjected to a new particle size reduction process that includes flow induced shearing provides for components in personal care formulations that have improved spreadability and substance as a consequence of a unique multiple particle size distribution.

Elastomer dispersion having a unique particle size distribution

A composition comprising the hydrosilylation addition product of a linear alkenyl functionalized polyorganosiloxane and an MH Q resin and a low molecular weight silicone when subjected to a new particle size reduction process that includes flow induced shearing provides for components in personal care formulations that have improved spreadability and substance as a consequence of a unique particle size distribution.

Processing of an elastomer dispersion

A composition comprising the hydrosilylation addition product of a linear alkenyl functionalized polyorganosiloxane and an MHQ resin and a low molecular weight silicone when subjected to a new particle size reduction process that includes flow induced shearing provides for components in personal care formulations that have improved spreadability and substance as a consequence of a unique particle size distribution.

A silicone elastomer dispersion

PROBLEM TO BE SOLVED: To reduce the average particle size of an elastomer, by repeating a process for applying pressure to a specific dispersion, passing the dispersion through an orifice to drop pressure and making the dispersion have a specific particle size distribution. SOLUTION: A process in which an elastomer having an initial average particle diameter and a particle size distribution is dispersed into a solvent to give a dispersion, which is pressurized, passed through an orifice to drop pressure and the initial average particle size is lowered, is repeated to make the dispersion have a maximum of about 21-26 μm, a maximum of about 33-38 μm and a maximum of about 50-60 μm. To be concrete, the composition of actualization form is obtained, for example, by applying shear force to affect the electric particle size distribution to the mixture of a linear alkenyl terminated polyorganosiloxane, a hydrosilylated addition product and a silicone and the distribution has unique properties.
