  • Patent number: 9801806
    Abstract: Provided in various embodiments are compositions for topical application to the skin of a mammal, methods for their preparation, and their uses in skin care compositions to reduce adhesion of unwanted particles to the skin. When a hydrophobic non-volatile solvent and a hydrophobic non-volatile high melting point material with a melting point in the range of 60° C. and 100° C. are combined with a hydrophobic volatile solvent which compatibilizes the hydrophobic non-volatile solvent and the hydrophobic non-volatile high melting point material and the hydrophobic non-volatile high melting point material is selected to be at least partially incompatible with the hydrophobic non-volatile solvent in the absence of the hydrophobic volatile solvent, the resulting composition may be applied to skin to reduce adhesion of unwanted particles to the skin.

  • Publication number: 20070290387
    Abstract: A lithography method includes the steps of: A) filling a mold having a patterned surface with a phase change composition at a temperature above the phase change temperature of the phase change composition; B) hardening the phase change composition to form a patterned feature; C) separating the mold and the patterned feature; optionally D) etching the patterned feature; optionally E) cleaning the mold; and optionally F) repeating steps A) to D) reusing the mold. The PCC may include an organofunctional silicone wax.

  • Patent number: 5017216
    Abstract: There is disclosed a herbicide composition in which a postemergent herbicide is activated by the inclusion of a silicone glycol adjuvant consisting essentially of (i) a silicone glycol having an average of 4 or 5 ethylene oxide units in its glycol chain and (ii) a silicone glycol dispersant compound for component (i). The composition provides enhanced phytotoxicity in the control of weeds, particularly velvetleaf plants, and shows an improved degree of rainfastness relative to prior art compositions.
