Abstract: The present invention provides a method of making alkali metal and alkaline earth metal salts of L-ascorbic acid 2-monophosphate comprising reacting a L-ascorbic acid 2-polyphosphate under alkaline conditions with an alkali metal or alkaline earth metal salt of L-ascorbic-acid in concentrated aqueous solution. The amount of the L-ascorbic acid salt is in molar excess of the polyphosphate and the pH value of the reaction medium is maintained in the range of from about 8 to about 11 wherein the reaction is carried out until substantially all of the polyphosphate has been consumed and only L-ascorbic acid 2-monophosphate salt is present. A further aspect of the present invention comprises spray drying the mixture obtained after completion of the reaction, cooling and dilution to a suitable viscosity.

Abstract: The invention generally provides the genes of the biotin biosynthetic operon of Bacillus subtilis, and closely related species thereof, and well as constructions useful for high level production of biotin.

Abstract: The invention is related to novel thiamacrolides, especially musk odorants, having extremely low threshold values, their use in functional perfumery such as fine perfumery, as well as to the preparation of thiamacrolide compounds.

Abstract: This invention is directed to cytochrome c.sub.551 polypeptides and polynucleotides encoding the polypeptides.

Abstract: Photostable, cosmetic light-screening composition, comprising, in a cosmetically acceptable vehicle containing at least one fatty phase, about 0.1 to about 5%, in particular about 1 to about 3% by weight, of a dibenzoylmethane type UV-A screening agent and at least about 0.5%, in particular about 0.5 to about 4.5% by weight, of a .alpha.-cyano-.beta.,.beta.-diphenyl-acrylate stabilizer, the mole ratio of the acrylate to the dibenzoylmethane derivative being less than 0.8, if the amount of the dibenzoylmethane is 1% or more, and, optionally, at least one conventional UV-B filter.

Abstract: The invention is concerned with a flowable dry particle consisting of at least one oleophilic substance as the active ingredient present in a matrix of at least one carrier material and a coating. The coating consists of calcium silicate or of a mixture of calcium silicate with one or more mixture components, with the mixture components being microcrystalline cellulose, magnesium silicate, magnesium oxide, stearic acid, calcium stearate, magnesium stearate, silicon dioxide, kaolin and/or hydrogenated vegetable oil.

Abstract: A process for the manufacture of a .gamma.-acetoxy-tiglic aldehyde by reacting a .gamma.-bromotiglic aldehyde or a .gamma.-chlorotiglic aldehyde with sodium acetate or potassium acetate in an organic solvent in the presence of a phase transfer catalyst.

Abstract: The present invention relates to the production of HPO lyase proteins in hosts via recombinant expression of said proteins. Recombinant HPO lyase proteins, DNA sequences encoding these proteins, vectors containing these DNA sequences and hosts containing these vectors are provided, along with methods for recombinantly producing such proteins, DNA sequences, vectors and hosts. Also provided are processes for producing green note compounds.

Abstract: Multiple micro-encapsulations of a high concentration oleophilic substance using heat to set the primary particle renders the composition suitable for the production of free-flowing powders or beadlets. Microencapsulation involves forming an emulsion out of the oleophilic substance and a polymer, and then use heat setting and/or cross-linking the polymer encapsulates the oleophilic composition. This process is then repeated with a second polymer or third polymer, and with or without cross-linked via the same or different mechanism to further protect the oleophilic substance.

Abstract: A process for the manufacture of polyene esters or polyene acids comprises reacting a polyene O,O-dialkylacetal of di(O,O-dialkylacetal) with a vinylketene acetal or analogue thereof in the presence of a Lewis acid, hydrolyzing the reaction mixture depending on the vinylketene acetal used, subsequently cleaving alcohol under strongly basic conditions from the polyene derivative produced at this stage and, where the desired ester or carboxy group is still not present, performing the respective conversion. Certain intermediates in this process form a further aspect of the invention. The final products are primarily carotenoids which can be used appropriately, e.g. as colorants and pigments for foodstuffs, animal products etc.
