  • Patent number: 8632832
    Abstract: The present disclosure describes a method for the continuous dissolution of e.g. crystalline astaxanthin or canthaxanthin suspension in oil, by applying heat for a predetermined period using an in-line or optionally batch wise-process, followed by cooling the heated solution with an oil phase or heat exchanger. The resulting oil solution may be used as such or added directly to feed components which are turned into feed compositions by extrusion, compaction or granulation. Alternatively the oil solution is spray coated or directly loaded to extruded or compacted pellets and granulates. The disclosure avoids using formulated carotenoids prepared by known multi-step production methods requiring solvents, solvent removal, cooling and emulsification with an aqueous phase or precipitation and recovery steps.

  • Publication number: 20080131499
    Abstract: Compositions for forming molecular associates with lipophilic compounds and an improved method of loading lipophilic biologically active compounds into previously formed, aqueous suspensions of lipid particles. A preferred embodiment for injection purposes comprise lipid particles having sizes below 1000 nm in diameter, in a vial or other suitable container are described. The method involves mixing a lipophilic compound either in solution or as an amorphous, preferably lyophilised powder in a first container with an aqueous suspension of lipid particles contained in a second container to form molecular associates. Only minimum agitation is required. The entire procedure may be carried out instantly in situ, in sealed sterile units just prior to use in the hospital ward or by the bedside.

  • Publication number: 20060286169
    Abstract: There is described dry compositions comprising lipophilic compounds associated with low viscosity grades of water insoluble polymer and optionally hydrophilic agent/s associated either as monomolecular or amorphous complexes. There is also described a method of preparing said lipophilic polymer complexes from a solution or homogeneous dispersion employing either water miscible or immiscible organic solvents. The lipophilic polymer complex is precipitated from the solution comprising a water miscible solvent by dilution with water, separating out the precipitated complex, washing, drying and conversion to oral and topical dosage forms. The lipophilic polymer complex may also be prepared by solvent removal involving spray drying or vacuum drying under elevated temperatures using either water miscible or water immiscible solvents. The compositions are characterised by improved dissolution and solubility of the associated compound in aqueous medium.

  • Publication number: 20060233846
    Abstract: The invention describes homogeneous microdispersions comprising at least one hydrogenated or partially hydrogenated membrane lipid with or without enzyme hydrolysis, dispersed in substantially non aqueous, non volatile hydrophilic medium with boiling point above 40° C. More preferably the compositions comprise a mixture of hydrogenated monoacyl and hydrogenated diacyl-lipids and at least one oil. The phospholipid mixture is obtained by controlled enzyme hydrolysis of lecithin or a specific phospholipid, followed by hydrogenation. The compositions have improved rheology, physical and chemical properties, functionality and industrial applicability. The microdispersions are used as such in all types of applications and as functional components with active compounds in products, particularly for improving skin function and facilitating skin repair due to UV damage and aging, in cosmetics and other topical products.

  • Publication number: 20060128665
    Abstract: There is described marine phospholipids (MPL) compositions suitable for human, aquaculture applications comprising a dry composition comprising nutritional components selected from the group consisting of marine phospholipids, marine proteins and amino acid blends obtainable by fluid extraction of a dried marine raw material. The compositions have low amounts of neutral lipids and particularly low amounts of cholesterol and cholesterol esters. They may be used either as such in powder form and for preparing purified MPL compositions by ethanol extraction. Both forms may be used as nutritional supplements, ingredients for functional foods and to optimise the delivery and containment of nutritional components in multicomponent fish feed compositions. There is further described a blend of the purified, ethanol extracted MPL compositions mixed with marine, vegetable, microbial or MCT oils to form liquid preparations for hard or soft gel encapsulation.

    Abstract: Compositions that are sprayable or that are in the form of discrete particles and that contain a lipid and a biologically active compound in the form of a micronized powder combine a high initial entrapment of the active compound in the membrane lipid with sustained release at the site of application as indicated by in-vitro and in-vivo tests. In a first form pro-liposomes are prepared by spraying under pressure through a nozzle a single composition comprising at least one volatile liquid propellant, at least one membrane lipid that is at least partly dissolved or dispersed in the propellant and at least one biologically active compound that is present in dispersion in the propellant and/or the lipid, the composition being free from other solvent for the lipid. In a second form the membrane lipid and the biologically active compound are minor components of micronized solid particles whose major component is a physiologically acceptable solid carrier.
