Abstract:
The disclosure relates to methods of reducing static on hair or a cloth material, reducing hair frizz and/or increasing shine on hair by wiping the hair or cloth material with a dry wipe product. The dry wipe product comprises a flexible substrate having a first side and a second side; and either an anhydrous composition, or an aqueous composition, disposed over the first and/or second side(s) of the flexible substrate. When hair or cloth material is wiped with a side of the dry wipe product having the anhydrous composition or the aqueous composition disposed thereon, the anhydrous composition or aqueous composition is transferred from the flexible substrate of the dry wipe product to the hair or cloth material. The anhydrous compositions and aqueous compositions of the instant disclosure reduce static on hair and/or cloth, reduce hair frizz and/or increase shine on hair. The dry wipe products of the instant disclosure are particularly beneficial for hair care because they are dry, portable, disposable, may be biodegradable, and comprise compositions that are safe for personal use.
Abstract:
The invention relates to methods of forming coated metal oxide particles, suspensions of such coated particles, particles comprising functionalised surface coatings and to fortification of food crops with coated metal oxide particles. Embodiments disclosed include a method of fortifying a food crop with a trace element, the method comprising growing the food crop in a growth medium comprising the trace element in the form of metal oxide particles coated with an organic compound, and a food crop fortified with a trace element in the form of metal oxide particles. Also disclosed is a method of forming coated particles, the method comprising: providing a first quantity of metal oxide particles; providing a second quantity of a coating material comprising an organic compound; and mechanically mixing the metal oxide particles with the coating material in a dry mixing process to provide a mixture comprising the metal oxide particles coated with the organic compound.
Abstract:
A stent with at least one severable supporting device and methods of coating using the same are disclosed. The severable supporting device can be an end tube or a tab attached to some portion of the stent by at least one “gate” or attachment. The end tube or tab may be part of the design of the stent when it is originally manufactured, or it may be attached to the stent in a secondary process by a biocompatible glue or solder. The end tube or tab can be used to support a stent during a coating process eliminating the need for a mandrel which would otherwise contact the stent during the coating process.
Abstract:
Disclosed is a coating composition and coated film having the coating composition adhered thereto in which the coating composition comprises particulate filler; binder composition comprising acrylic polymer and ethylene acrylic acid copolymers; non-cross-linking adhesion promoter; and optionally urethane polymer, styrene-acrylic copolymer, or a combination thereof; and wherein cross-linker(s) are substantially absent from the composition; and wherein the coated film has a 45° Gloss (ASTM D2457) of less than 30 or 25 or 20 or 15. The coated film is useful for pressure sensitive labels for thermal transfer ribbon printing labels.
