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 |

20110009571 | SYSTEMS AND METHODS FOR DELIVERY OF MATERIALS - Systems and methods for delivering release materials, for example drugs and other bioactive materials. Crystalline polymeric systems, referred to as CYC carriers, are associated with the release materials, through chemical bonding or through physical association. The crystallinity of the CYC carriers results from the presence of crystallizable side chains, for example long chain n-alkyl moieties, which results in relatively low and sharp melting temperatures. One class of CYC carriers, referred to as CYSC polymers, have a majority of the crystallizable side chains pendant from the polymer backbone. Another class of CYC carriers referred to as ECC polymers, have a majority of the crystallizable side chains attached to terminal units of the polymer backbone. The ECC polymers can for example be obtained by modification of PLGA polymers. The CYC carriers in another class of non-polymeric. Some CYC carriers, referred to as CYC assemblies, have enhanced crystallinity as a result of the physical association of crystallizable moieties which are present in different types of molecule, for example between a polymer containing crystallizable moieties and a monomer containing crystallizable moieties. For some uses, particularly the delivery of drugs, a bioerodable CYC carrier is preferably used. | 01-13-2011 |

20140093471 | AIR AND FABRIC FRESHENER - The present invention relates to a stable, aqueous freshener composition for the reduction or elimination of malodors in air and on fabrics. The composition comprises from about 0.1% to about 3.0% by weight, hydrogen peroxide as a malodor oxidant; an effective level of undecylenic acid (and/or derivative thereof) as a malodor absorber preblended with a fragrance; a surfactant to solubilize the fragrance/malodor absorber blend; an acid based stabilizer in a range from about 0.008% to about 0.60% by weight; an optional pH buffer; and an aqueous carrier. The composition can be delivered via a spray dispenser for treatment of indoor air and fabrics. The composition has a pH of less than about 6 and does not contain ingredients known to soil, stain or damage fabrics. When applied as a fine mist, the composition delivers effective control of a broad range of malodors, while remaining imperceptible on surfaces when dry. | 04-03-2014 |
