Shaped articles which are suitable as biocidal depth-type filters and consist of fibrous materials and particles, embedded therein, of crosslinked crospovidone-iodine or crospovidone-hydrogen peroxide.

Depth-type filter for killing microorganisms and inactivating viruses and its use

The invention provided relates to the use of polyvinylpyrrolidone-iodine complexes in combination with gelling agents to produce strong disinfectants which not only physically stabilize biohazardous and infectious wastes but also kill pathogens contained in the wastes. The gelling agents include polyacyrlates that are superabsorbents.

Compositions for disinfecting wastes

The present invention relates to a 1,3-bis-(N-lactamyl)propane of general formula (I), wherein radicals R , R , R , R , R and R independently stand for hydrogen, alkyl, cycloalkyl, aryl or aralkyl and at least one of said radicals does not stand for hydrogen, (NLac) and (NLac&prime;) are the same or different and stand for N-lactamyl radicals. The invention also relates to the use of said substances as a solvent in pharmaceutical and cosmetic agents. Disclosed are novel compounds of formula (I), wherein R and methyl and R -R stand for hydrogen.

1,3-bis-(N-lactamyl) propane and the pharmaceutical and cosmetic use thereof

The present invention relates to topical products intended for use as prophylactic or curative agents for bacterial skin infections, containing at least one polymeric complex substantially consisting of hydrogen peroxide, a suitable polymer for the complex formation thereof, possibly another bactericidal compound and possibly a metal salt or a metal colloid.

Topical Products as prophylactic of curative agents for bacterial skin infections

Methods for disinfecting wastes

Complexes in powder form of iodine and a crosslinked polymer based on N-vinyl compounds are obtainable by dry heating of iodine and a polymer which is obtained by polymerization of monovinyl compounds (monomers A) whose vinyl group is bonded to a nitrogen atom of a nitrogen-containing heterocycle, in the presence of from 0.5 to 10% by weight, based on the monomers (A), of a compound (B) of the formula I;

Powdery iodine complexes

A process for treating cooling lubricants to prevent attack by microorganisms using crospovidone-iodine as biocidal substance, wherein the cooling lubricant to be treated is brought into contact with a filter cake which consists essentially of particulate crospovidone-iodine as filter medium.

Process for the antimicrobial treatment of cooling lubricants

Process for purifying alkoxylated fats

Depth-type filter for killing microorganisms and inactivating viruses

Polymer complexes which comprises hydrogen peroxide, a polymer suitable for complex formation with hydrogen peroxide, and at least one metal colloid and/or metal salt are prepared as described and used in bactericidal compositions, disinfectant systems, hair cosmetic compositions and as free-radical initiators for chemical reactions.

Polymer/hydrogen peroxide complexes

Pyrrolidonyl-containing polyesters and polyamides

Direct tabletting aids

Direct tableting auxiliaries essentially consists of

Direct tableting auxiliary

Process for the preparation of solid pharmaceutical forms by mixing one or more pharmaceutical active compounds with one or more fusible, pharmacologically tolerated binders and, if required, other conventional pharmaceutical auxiliaries, at from 50.degree. to 180.degree. C., and subjecting the mixture to injection molding or extrusion and shaping, wherein the fusible binder used is a NVP polymer which contains not less than 20% by weight of NVP as copolymerized units, and, where they are present, all of whose comonomers contain nitrogen and/or oxygen.

Preparation of solid pharmaceutical forms

Polyvinylpyrrolidone having a Fikentscher K value of from 14 to 95 is prepared at from 50.degree. to 95.degree. C. in aqueous solution with hydrogen peroxide as starter, the solution being maintained at pH 7-11 by means of NaOH, KOH, their carbonates or bicarbonates.
