A method of delivering an active compound includes providing a delivery device having a first portion. The first portion defines a first outer surface of the device. An active compound is provided in the first portion. The first outer surface exhibits a first tack after providing the active compound and a second tack of at least 25 percent the first tack after delivering the active compound to the first outer surface.

Solvent-swollen crosslinked silicone gels containing covalently bonded cyclodextrin groups are prepared by hydrosilylation. The swollen gels are storage stable, compatible with water and polar solvents, and display a significant water break effect.

An aqueous dispersion along with methods for producing and uses for the same. Where the aqueous dispersion includes crosslinkable reactive silicone organic copolymers of ethylenically unsaturated monomers and of ethylenically functionalized silicone polymers and is obtainable by means of radically initiated miniemulsion polymerization in an aqueous medium.

Organopolysiloxane gels containing a hydrocarbon diluent and non-chemically bonded natural oils are prepared by the hydrosilylative gelling of a mixture of an aliphatically unsaturated organopolysiloxane, an Si&#x2014;H-functional organopolysiloxane, and a long chain &#x3b1;-olefin, in the presence of a hydrocarbon diluent and at least one natural oil. Stable creamy gels are produced by shearing the gel product, and contain only a minor amount of crosslinked organopolysiloxane elastomeric component.

Silicone elastomer gels incorporating natural oils

Defoamer compositions contain a) a two-stage hydrosilylation product of one or more MQ or MTstarting materials with a hydrosilylatable composition containing &#x3b1;-methylstyrene, and then with a linear or branched organopolysiloxane bearing at least two hydrosilylatable groups; b) a silicone resin; and c) silica. The defoamers are particularly useful in machine laundering and dishwashing compositions.

Silicone defoamer compositions

Water-in-oil invert emulsions containing no surfactant are formed by simple mixing of water with organopolysiloxanes containing all of aralkyl, long chain alkyl, and hydrophilic groups. The surfactant-free water-in-oil invert emulsions have a wide variety of uses, for example in compositions for surface care, antifog coating compositions, cosmetic compositions, and hair care compositions.

Surfactant-free organopolysiloxane invert emulsions

Branched organopolysiloxanes of low molecular weight contain bonded arylalkyl groups. Si&#x2014;C bonded surfactant groups, preferably polyoxyalkylene polyether groups, and long chain alkyl groups, exhibit a high refractive index, are completely or partially self-emulsifying, and are compatible with a variety of cosmetically acceptable oils and solvents.
