  • Patent number: 9005584
    Abstract: Spray compositions are formulated with powders (e.g. corn starch) which improve skin feel, and also have a hydrophobically modified oxide additive (e.g. modified silica) to reduce the incidence of can/bottle clogging and sedimentation caused by the powder. The oxide is a mixed hydrophobic/hydrophilic oxide such as hydrophobicly modified fumed silica (e.g. silica dimethyl silylate). In one embodiment DEET can be delivered by such formulations.

  • Patent number: 7980486
    Abstract: Disclosed are dispensers for volatile materials. There is a container in the form of a well having an internal cavity, a volatile chemical positioned in the cavity, and a multi-layer covering enclosing the cavity. The covering has a lower section that is gas permeable, and an upper section removably bound to the lower section that is not. Embodiments include when (a) the lower section has a top layer that is a blend of high density polyethylene and low density polyethylene; the upper section has a bottom layer that has a mixture of polypropylene and a propylene/ethylene copolymer; and/or the lower section has an upper layer that has low density polyethylene but the lower section does not contain ultra low density polyethylene. These features help prevent premature leakage at the bond between the upper section and lower section.

  • Patent number: 7416766
    Abstract: Bottles made of metallocene polypropylene (mPP) for storage and dispensing reservoirs for fragrance compositions, in particular fragrance oils, are described. The mPP bottles can be used in warmer units for slow release dispensing of the fragrance therein. The metallocene polypropylene bottles can be produced by extrusion or injection blow molding, injection molding, injection stretch blow molding (single or two stage), or other suitable molding process. The mPP bottles may optionally have at least one barrier coating layer and/or adhering layer. The mPP bottles may optionally be fluorinated. The mPP bottles have good clarity and possess the required physical properties needed when the bottles are filled on a production line.

  • Patent number: 7281811
    Abstract: The present invention is directed toward apparatuses, devices, methods, kits, programs, and combinations to disperse and/or project light. For example, in one embodiment of the present invention where a light effect of glowing, diffuse, and projected light is desired, one lens is provided that diffuses light in one section of the lens and is substantially clear in another section to allow substantially all the light to pass through the lens. In other embodiments to obtain the same effect, one or more lenses diffuse light while one or more other lenses are clear to allow substantially all the light to pass through the lens.

  • Patent number: 5100961
    Abstract: Copolymer-containing compositions are prepared by the reaction of an epoxytriazine-capped polyphenylene ether with another polymer containing amine end groups, especially a polyamide, under intimate blending conditions. The compositions have excellent properties and find utility as molding compositions and as compatibilizers for blends of similar polymers. Suitable epoxytriazine-capped polyphenylene ethers may be prepared by reaction of a polyphenylene ether with an epoxychlorotriazine such as diglycidyl chlorocyanurate, n-butyl glycidyl chlorocyanurate or mesityl glycidyl chlorocyanurate.
