Methods, systems, and apparatuses for nanomaterial-enhanced platelet binding and hemostatic medical devices are provided. Hemostatic materials and structures are provided that induce platelet binding, including platelet binding and the coagulation of blood at a wound / opening caused by trauma, a surgical procedure, ulceration, or other cause. Example embodiments include platelet binding devices, hemostatic bandages, hemostatic plugs, and hemostatic formulations. The hemostatic materials and structures may incorporate nanostructures and / or further hemostatic elements such as polymers, silicon nanofibers, silicon dioxide nanofibers, and / or glass beads into a highly absorbent, gelling scaffold. The hemostatic materials and structures may be resorbable.

The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, cleaning or fabric care compositions, such particles increase the efficiency of benefit agent delivery, there by allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed.

Described herein are organoaminosilane precursors which can be used to deposit silicon containing films which contain silicon and methods for making these precursors. Also disclosed herein are deposition methods for making silicon-containing films or silicon containing films using the organoaminosilane precursors described herein. Also disclosed herein are the vessels that comprise the organoaminosilane precursors or a composition thereof that can be used, for example, to deliver the precursor to a reactor in order to deposit a silicon-containing film.

The present application relates to encapsulated benefit agents, compositions comprising such encapsulated benefit agents and processes for making and using compositions comprising such encapsulated benefit agents. Such encapsulated benefit agents eliminate or minimize one or more of the drawbacks of current encapsulated benefit agents and thus provide formulators with additional perfume delivery opportunities.

The invention is directed to a structured liquid fabric treatment composition comprising as added components one or more silicone-based cationic fabric care ingredients preferably selected from the group consisting of cationic silicone polymers comprising one or more polysiloxane units and one or more quaternary nitrogen units; a structuring system comprising a structuring agent, a nonionic emulsifier and an anionic emulsifier; a cationic scavenging agent for the anionic emulsifier and a liquid carrier.

A coating composition for fabrics includes wetted microspheres containing a phase change material dispersed throughout a polymer binder, a surfactant, a dispersant, an antifoam agent and a thickener. Preferred phase change materials include paraffinic hydrocarbons. The microspheres may be microencapsulated. To prepare the coating composition, microspheres containing phase change material are wetted and dispersed in a dispersion in a water solution containing a surfactant, a dispersant, an antifoam agent and a polymer mixture. The coating is then applied to a fabric. In an alternative embodiment, an extensible fabric is coated with an extensible binder containing microencapsulated phase change material to form an extensible, coated fabric. The coated fabric is optionally flocked. The coated fabrics are manufactured using transfer techniques.

In an aspect of the invention, a fluoropolymer dispersion, preferably a PTFE dispersion, is provided that comprises fluoropolymer particles having an average particle size of 10 to 400 nm dispersed in water whereby the dispersion has an amount of solids between 35 and 70% by weight. The dispersion is free of fluorinated surfactant having a molecular weight of less than 1000 g / mol (hereinafter called low molecular weight fluorinated surfactant) or contains the low molecular weight fluorinated surfactant in an amount of not more than 0.05% by weight based on the total weight solids of the dispersion. The dispersion further comprises a non-ionic non-fluorinated surfactant or mixture of non-ionic non-fluorinated surfactants and one or more non-fluorinated anionic surfactants. Through the use of a non-fluorinated anionic surfactant, a dispersion is obtained that has a low viscosity at room temperature (20° C.). The dispersion is further free of aromatic group containing non-ionic surfactants and is accordingly environmentally more friendly and can yield coatings that are less susceptible of discoloration. The amount and nature of the non-ionic non-fluorinated surfactant or mixture of non-ionic non-fluorinated surfactants is selected such that the Viscosity Transition Temperature (VTT) (measured as set forth in the examples) of the fluoropolymer dispersion is at least 26, preferably at least 28° C. In a further aspect of the invention, a method is provided to obtain the aforementioned dispersion.

Compounds and compositions comprising specific metal salts of hexahydrophthalic acid (HHPA) in order to provide highly desirable properties within thermoplastic articles are provided. The inventive HHPA derivatives are useful as nucleating and / or clarifying agents for such thermoplastics, are practical and easy to handle. Such compounds provide excellent crystallization temperatures, stiffness, and acid scavenger compatibility within target polyolefins. Also, such compounds exhibit very low hygroscopicity and therefore excellent shelf stability as powdered or granular formulations. Thermoplastic additive compositions and methods of producing polymers with such compounds are also contemplated within this invention.
