摘要:
Process for the preparation of a spreadable edible dispersion wherein a mixture of oil and solid structuring agent particles is subjected to stirring and an aqueous phase and/or solid phase is gradually added to the mixture until a dispersion of the desired oil content is obtained, wherein the solid structuring agent particles have a microporous structure of submicron size particles.
摘要:
The present invention relates to a polymerizable composition comprising a) at least one ethylenically unsaturated monomer and b) at least one hydroxylamine of high molecular weight, preferably a long chain alkyl substituted hydroxylamine. Further aspects of the present invention are a process for polymerizing ethylenically unsaturated monomers, and the use of high molecular weight hydroxylamines for controlled polymerization.
摘要:
The invention relates to the preparation of polyamides in the presence of a phosphonate, which is already added at the beginning of the polycondensation or polyaddition process. The resulting prepolymer exhibits a high molecular weight and is almost colorless. A further aspect of the invention is the use of a phosphonate for increasing the molecular weight and modification of polyamides during polycondensation.
摘要:
Photochromic compositions are disclosed comprising a polymeric material, a photochromic dye, a hydroxyphenyl triazine UV absorber and, optionally, a further light stabilizer selected from the sterically hindered amines. These systems provide a reversible photochromic effect and show improved light stabilization and color fastness.
摘要:
The instant invention relates to new photolatent compounds of the formula I wherein R1 and R2 are each independently of the other C1-C10alkyl or C3-C8cycloalkyl, R3 is hydrogen or C1-C4alkyl, and wherein the photochemically cleaved group R4OH is selected from the group consisting of fragrances, UV absorbers, anti-microbials, anti-fogging agents and clarifiers; with the proviso that, when R1 and R2 are tert-butyl and R3 is hydrogen, R4 is not methyl or phenyl.

摘要:
Solid dosage forms containing at least one polymer binder, at least one active ingredient and, where appropriate, conventional additives, wherein a physiologically tolerated, water-swellable graft copolymer or a mixture of graft copolymers is employed as polymeric binder.
摘要:
The present invention relates to a process of preparing a polycondensate in the presence of a fluorescent whitening agent and at least one phosphonate, and/or phosphinate. Further aspects of the invention are a polyester prepared according to this process and composition comprising a polycondensate, a fluorescent whitening agent and at least one phosphonate and/or phosphinate. Yet another aspect is the use of a fluorescent whitening agent and at least one phosphonate and/or phosphinate for improving the color of a polycondensate.

摘要:
The contents of clear or lightly colored plastic containers or films are protected from ultraviolet radiation by the incorporation of certain UV absorbers of the class of reactable, durable hydroxyphenylbenzotriazoles in the container or film. The hydroxyphenylbenzotriazoles are reacted into the containers or films via condensation reaction and are thereby covalently bonded therein. Contents to be protected include foodstuffs, beverages, pharmaceuticals, cosmetics, personal care products, shampoos and the like.
