Abstract:
The present invention relates to a method for producing polymer-encapsulated nanoparticles comprising the steps of: pumping supercritical fluid into a pressurised vessel, at a predetermined pressure; spraying a solution comprising a compound to be encapsulated, a polymer and an organic solvent into the vessel; collecting precipitated particles on a filter; and washing the particles with the supercritical fluid to remove residual solvent; characterised in that: the difference between the melting point of the polymer and the melting point of the compound to be encapsulated is not more than 10° C.
Abstract:
Corrosion control in reinforced concrete is generally disclosed. Some example embodiments may include concrete including aggregate, cement, and/or microcapsules distributed within the cement, where the individual microcapsules may include a high pH salt substantially contained within an acid-soluble shell. If the pH of the concrete decreases, the acid soluble shell may swell and/or dissolve, such as below a pH of about 11, which may release the high pH salt. The high pH salt may locally increase the pH of the concrete. By increasing the pH above about pH 11, corrosion of steel rebar may be prevented and/or reduced.
Abstract:
Disclosed is a two-component fluid loss control system comprising a core substrate and a polymeric shell cooperating with each other to form a microcomposite, wherein the core substrate and the polymeric shell are formed from different materials. The system can demonstrate switchable behavior. The core substrate and the polymeric shell can be further modified, where modifications cooperate with each other to form the microcomposite. Also disclosed are formulations for fluid loss control and methods for controlling fluid loss in a well.
Abstract:
A method of preparing nano-dispersed high-all-trans-carotenoid microcapsules is provided, comprising: preparing 10-20% carotenoid suspension by milling the high-all trans-carotenoid crystals with dichloromethane until the particle size thereof is in the range of 2-5 μm, then supplying the suspension together with preheated dichloromethane of another pass into a dissolving tank to obtain a solution of 0.5-2%; delivering the solution together with ethanol or isopropanol into a crystallization device having high gravity rotating packed bed simultaneously and continuously, and then into a wiped-film evaporator for desolvation until the solid content is 10-20%, then a transparent alcohol dispersion of carotenoid is obtained; mashing the alcohol dispersion together with an aqueous solution containing an antioxidant and protective colloid and spray drying to obtain nano-dispersed high-all-trans-carotenoid microcapsules. As the crystals are nano-dispersed and the content of trans-isomer is more than 90%, the carotenoid microcapsules of present inventions exhibit high bioavailability.
Abstract:
Agents for lightening and/or bleaching keratin-containing fibers, particularly human hair, comprising coated bleaching and/or alkalizing agents. The agent provides uniform lightening regardless of which strands are treated first or last with the hair-bleaching agent. The present invention further relates to a method for producing lightening and/or hair-bleaching agents for keratinic fibers containing coated particles.
Abstract:
A composition includes a first component containing phospholipids and a second component encapsulating the first component. The composition includes between about 10% and about 80% by weight phospholipids. The composition may be used in chewing gum to provide a gum cud that does not adhere to concrete and does not dissolve in the mouth while chewing.
Abstract:
Perfuming or flavoring microcapsules that include a fireproofing agent in addition to a perfuming or flavoring ingredient and a carrier material, so that the microcapsules can reduce the occurrence or an explosion of reduced violence when suspended in hot air during their preparation. Also, methods of making these microcapsules and their use in perfumed, food, beverage or pharmaceutical products.
Abstract:
Multimicrocapsules that include encapsulated components of at least one nutritionally, pharmacologically, or medically active functional substance, wherein, within an encapsulation of one or more layers of a first encapsulating material around a common capsule matrix, there are provided a first active functional component in an amount sufficient to provide functional benefits after being ingested by a subject and a component preserving or function enhancing substance present in an amount to preserve and enhance the functional benefits of the active functional component. The encapsulation delays release of the active functional component when the microcapsules are ingested by the subject and provides a synchronous or tuned release of the active functional component and component preserving or function enhancing substance in the intestine of the subject. Also, a process and apparatus for forming such microcapsules.
