  • Patent number: 8053517
    Abstract: This invention pertains to neutralized silicone elastomer dispersions and methods for making neutralized silicone elastomer dispersions. This invention also pertains to compositions comprising the neutralized silicone elastomer and an acid reactive compound. The silicone elastomer dispersion are neutralized typically by blending the silicone elastomer dispersion with a base such as sodium bicarbonate or by adding a basic neutralizing agent to one or more of the raw materials used to make the silicone elastomer dispersion and removing the basic neutralizing agent by filtration or any other suitable means.

  • Patent number: 7914645
    Abstract: A silicone adhesive composition used for adhering a device or a substance to a wet surface contains (i) a silicone resin that is cohydrolysis product of a trialkyl hydrolyzable silane and an alkyl silicate in which the cohydrolysis product contains a plurality of silicon-bonded hydroxy groups; (ii) a linear organopolysiloxane fluid containing terminal silicon-bonded hydroxy groups having a viscosity above 200,000 mm2/s at 25° C.; (iii) a trialkylsiloxy terminated polyorganosiloxane fluid having a viscosity of 100,000-600,000 mm2/s at 25° C.

  • Publication number: 20100202986
    Abstract: A composition comprises a mixture of a silicone and a solvent. The composition further comprises a drug selected from the group of retinoids, retinyls, vitamin A esters, vitamin D analogues, and combinations thereof. The composition further comprises a salt of a dialkyl sulfosuccinate, such as dioctyl sodium sulfosuccinate (DOSS). The composition yet further comprises and a solubilizer. The salt of a dialkyl sulfosuccinate solubilizes the drug. The solubilizer solubilizes the salt of a dialkyl sulfosuccinate. The composition can be topically applied to a substrate, such as skin, for delivering the drug. Drugs with a wide solubility range are soluble and compatible in the composition without separation or crystallization of the drugs occurring.

  • Publication number: 20100184714
    Abstract: A composition comprises a mixture of a silicone and a first solvent, a drug, such as a hydrophilic or lipophilic pharmaceutical agent, a salt of a dialkyl sulfosuccinate, such as dioctyl sodium sulfosuccinate (DOSS), and a second solvent, such as an alcohol. The salt of a dialkyl sulfosuccinate solubilizes the drug. The composition can be topically applied to a substrate, such as skin, for delivering the drug. Drugs with a wide solubility range are soluble and compatible in the composition without separation or crystallization of the drugs occurring.

  • Patent number: 6337086
    Abstract: A transdermal drug delivery device for the controlled transdermal delivery of an active pharmaceutical agent. The device comprises a drug delivery device comprising an active pharmaceutical agent and a means for its controlled delivery through the skin; and (B) a silicone pressure sensitive adhesive for maintaining contact between the device and the skin of a wearer. The silicone pressure sensitive adhesive comprises silicone resin copolymer and a polydiorganosiloxane and has a silanol concentration in the range of between about 8000 and about 13,000 ppm. The present invention also relates to methods for producing the above silicone pressure sensitive adhesive compositions.

  • Patent number: 5989579
    Abstract: A flexible ocular insert device adapted for the controlled sustained release of an ophthalmic drug into the eye. In one embodiment, the device includes an elongated body of a polymeric material in the form of a rod or tube containing a pharmaceutically active ingredient and with at least two anchoring protrusions extending radially outwardly from the body. The device has a length of at least 8 mm and the diameter of its body portion including the protrusions does not exceed 1.9 mm. The sustained release mechanism may, for example, be by diffusion or by osmosis or bioerosion. The insert device is advantageously inserted into the upper or lower fornix of the eye so as to be independent of movement of the eye by virtue of the fornix anatomy. The protrusions may be of various shapes such as, for example, ribs, screw threads, dimples or bumps, truncated cone-shaped segments or winding braid segments.
