An emulsion is disclosed which comprises a non-aqueous phase comprising a solid silicone resin and a siloxane carrier vehicle having an average of at least one silicon-bonded functional group per molecule and capable of carrying the solid silicone resin, an aqueous phase comprising water, and a surfactant, wherein the emulsion is substantially free from organic solvents. Various methods relating to the emulsion and end uses thereof are also disclosed. A composition comprising the emulsion and an organic binder, as well as related methods, are further disclosed.

Emulsion, composition comprising same, film formed therewith, and related methods

A process for increasing the hydrophobicity of a porous product by treating the product, or a composition providing for the product, with a water repellent material, characterized in that the porous product or a composition providing the product, is treated with an aqueous suspension of microcapsules where the microcapsules comprise a water repellent organosilicon core material selected from an organosilane, a partially condensed organosilane and a branched siloxane resin, and a shell of a silicon-based network polymer comprising silica units.

Water repellent organosilicon materials

A process for preparing silicate shell microcapsules comprises adding a water reactive silicon compound to an oil in water emulsion, thereby condensing and polymerizing the water reactive silicon compound to form silicate shell microcapsules having a core comprising the oil phase of the said emulsion. The water reactive silicon compound comprises a tetraalkoxysilane and an alkoxysilane having an amino or quaternary ammonium substituted alkyl group.

Process for preparing silicate shell microcapsules

A fabric, fiber, hair or skin conditioning additive for use in a liquid cleaning product is encapsulated within a shell comprising a silicon-containing polymer network.

Fabric and fibre conditioning additives

The present invention relates to a controlled release carrier system that can be incorporated into rinse-off application products containing at least one surfactant such as heavy duty liquids (HDL), Rinse Cycle Fabric Softeners (RCFS), Shampoos, Hair Conditioners, Shower Gels, cleansing products, and that enhance deposition of lipophilic active materials like fragrance, fine perfumes, flavors and other volatile compounds onto a surface. The fragrance composition is encapsulated within a shell comprising a silicon-containing material and the shell has a mean diameter size which is lower than 30 micrometer. The surfactant composition containing the fragrance composition is washed off and the fragrance is progressively released.

Deposition of lipophilic active material in surfactant containing compositions

Aqueous suspensions of silicate shell microcapsules are disclosed wherein a first portion of the silicate shell micro-capsules contain an organopolysiloxane having at least two alkenyl groups and a hydrosilylation catalyst as Part A of a curable siloxane composition, and a second portion of the silicate shell microcapsules contain an organohydrogensiloxane as Part B of the curable siloxane composition.

Microcapsules containing curable siloxanes

A process is disclosed for preparing microcapsules having a shell thickness of at least 18 nanometers by polymerizing a tetraalkoxysilane at the oil/water interface of an emulsion containing 0.1 to 0.3 weight percent of a cationic surfactant. The microcapsules are useful to prepare encapsulated sunscreens having sufficient robustness to prevent leakage of the encapsulated sunscreen in a formulated composition.
