  • Patent number: 6103770
    Abstract: The present invention relates to the use of ethoxylated fatty acid esters self-emulsifiable compounds particularly useful for the preparation of phytosanitary treatment products or as drugs for veterinary or human use. According to the invention, said fatty acid esters comprise a total number of ethylene oxide molecules such that the HLB value (hydrophilic-lipophilic balance) of said compounds is comprised between about 4 and about 10, preferably between about 5 and about 9. Said ethoxylated fatty acid esters form in an original way self-emulsifiable components without requiring any other surfactant, and they are biodegradable and capable of dissolving active principles which are little or non water-soluble.

  • Patent number: 5424067
    Abstract: The present invention relates to injectable multi-phase solutions of W/O/W type, usable as vaccines or as vehicles of active substances in human and veterinary medicine, which are pharmaceutically acceptable in each one of their constituents, stable for at least 12 months in storage at 4.degree. C., of viscosity less than 300 mPas and comprise at least the following constituents:an oily adjuvant composed of:a water-immiscible oily phase representing between 20 and 70% of the formula,an emulsifying system selected so that the inversion point of the resulting emulsion ranges between 25.degree. and 45.degree. and represents between 2 and 10% of the formula,an aqueous phase containing the antigens or the active substances and representing between 20 and 78% of the formula and obtained in a single mixing operation.

  • Patent number: 5422109
    Abstract: The present invention relates to an injectable emulsion, usable as a vaccine or active principle vehicle, which has an oily continuous phase with a good tolerance under normal conditions of injection into a human or an animal, said emulsion being characterized by a viscosity of less than 800 mPas at 20.degree. C. and consisting of at least20 to 90% of an oily adjuvant which is liquid at 4.degree. C. and contains at leastone or more appropriate and pharmaceutically acceptable emulsifiers anda mixture, in any proportions, of one or more metabolizable oils with one or more non-metabolizable oils, and10 to 80% of a hydrophilic phase containing the active principles or antigens.

  • Patent number: 5393333
    Abstract: The present invention relates to a film-forming product for coating solid forms, to a process for the manufacture of this film-forming product and to products coated with this film-forming product. According to the invention, this film-forming product takes the form of homogeneous granular particles which can easily be dispersed in an aqueous or organic solvent and which make it possible to obtain a uniform non-matt film, and its dry matter comprises:at least one ingestible, non-toxic film-forming substance in an amount of between 30 and 95% by weight;at least one colored pigment in an amount of between 5 and 50% by weight; andif appropriate, at least one edible plasticizer in an amount less than or equal to 30% by weight.

  • Patent number: 5164014
    Abstract: The present invention relates to a process for the preparation of grains of starch, which comprises granulating a mixture obtained by spraying 1 to 20%, and preferably 2 to 6% by weight, of a starch paste obtained from native starch under mild conditions, on to 99 to 80% by weight of grains of native starch, and drying, grinding and sieving the resulting product to give aggregates (grains) having a mean particle size of between 100 and about 500 .mu.m.

  • Patent number: 5137747
    Abstract: The present invention relates to a novel desiccant powder and its use for the drying of solid substrates wetted by an aqueous or oily liquid such as, in particular, grains or seeds having undergone a coating or surface film-forming treatment.According to the invention, this desiccant powder contains at least 50% by weight of absorbents with respect to the toal weight of the said powder, being preferably available in the form of particles having a mean diameter less than about 100.mu., the said absorbents being constituted of at least one aluminosilicate, in particular mica, to at least 25% by weight with respect to the total weight of the said absorbents.This powder makes possible, in particular, the drying of colored grains or seeds.
