20150219505 | Thermochromic Indicators - A thermochromic indicator includes a coating on the substrate. The coating comprising a solid crystalline particles having a melting point of 0-130° C. At temperatures below the melting point, the coating is opaque. At temperatures above the melting point, the coating becomes translucent. The change in opacity can be reversible or irreversible. | 08-06-2015 |
20140262262 | Compositions and Methods for the Controlled Release of Active Ingredients - This invention discloses articles, in the form of particles to small granules to macro sized objects, capable of the controlled release of active ingredients (AI) from a mixture as a solid solution, a matrix or an encapsulated system containing AI and one or more of polymers, additives and/or carriers. The invention also covers additional surface coatings on those articles to further reduce the rate of release of AI. Finally, methods for producing these articles and treating the oil field well and other segments of the oil industry, for example piping, storage tank, and refinery locations, are introduced. The claimed articles can be used as is or mixed with other oil filed components or system, for example proppant fluid, in oil field applications. | 09-18-2014 |
20130243839 | Controlled, Sustained Release Particles for Treating Seeds and Plants and Methods for Making the Particles - The invention relates to active particles, including core-shell particles, having low burst, controllable, sustained release which are useful for coating seeds. The active particles can also be used in sprayable and dry formulations for treating soil or plants. The particulate coating can also contain inert organic or inorganic material. The invention also relates to methods for preparing the active particles. The methods include: adding additional material to core particles to form a shell, removing active ingredient from a core surface to create an active-depleted shell, and crosslinking the outer layers of a core to form a shell. | 09-19-2013 |

The active particles can also be used in sprayable and dry formulations for treating soil or plants. The particulate coating can also contain inert organic or inorganic material. The invention also relates to methods for preparing the active particles. The methods include: adding additional material to core particles to form a shell, removing active ingredient from a core surface to create an active-depleted shell, and crosslinking the outer layers of a core to form a shell. | 08-22-2013 |
20130195775 | IONIC/IONOGENIC COMB COPOLYMER COMPOSITIONS AND PERSONAL CARE PRODUCTS CONTAINING THE SAME - Ionic and ionogenic comb copolymers are disclosed along with personal care products that employ them as a modifier that results in increased sensory attributes and increased effectiveness in the deposition of actives and can also act as a thickening agent. The copolymer includes one or more repeating units derived from olefinically unsaturated anionic or anionogenic or zwitterionic comonomers, and one or more repeating units having the formula | 08-01-2013 |
20120142581 | Polymer Formulations for Delivery of Bioactive Materials - PLGA, PLA and PGA polymers which have crystallinity resulting from the presence of long chain alkyl groups in terminal units. The polymers are particularly useful for drug delivery. | 06-07-2012 |
20120088659 | Compositions and Methods for Delivery of Materials - Compositions for the controlled delivery of active ingredients, for example, drugs, cosmetic materials, and agricultural materials. The compositions include a multiplicity of particles, each of the particles comprising (1) a microstructure comprising a semicrystalline polymer which has a peak melting temperature, Tp, of at least 20° C., and (2) the active ingredient. The microstructure comprises

20120082709 | COMPOSITIONS AND METHODS FOR DELIVERY OF MATERIALS - Compositions for delivering release materials, for example drugs, agricultural materials, other bioactive materials, cosmetic materials, organic or inorganic compounds which take part in or catalyse a chemical reaction, a fragrance-emitting material for a vaporizer, or a lubricating material. The release material is associated with a crystalline carrier. The carrier may be a crystalline polymer containing a plurality of crystalline groups or a crystalline monomer which contains a single crystalline group, the crystalline group preferably comprising a straight chain polymethylene radical containing at least 16 carbon atoms. Some of the carriers are obtained by modifying hyaluronic acid, collagen, gelatin, a polysaccharide, a carbohydrate or cyclodextran. The release material may contain a similar crystalline group, for example may be an active compound which has been modified to introduce a crystalline group. | 04-05-2012 |
