Disclosed are oligo- or polysiloxanes, which are characterized by containing at least 3, for example 4-3000, Si atoms in the main chain, and wherein at least one thereof is contained in a moiety of the formula (I) whose variables and attachments are described within.  The disclosed are oligo- or polysiloxane compounds are effective as antimicrobials.

Polysiloxane antimicrobials

The invention relates to cationic siloxane derivatives for use especially as fungicides and/or antiadhesives. The cationic siloxane derivatives have the formula (I), wherein R1, R2, R3, R4, R', R5 and n are as defined in the description. 

Antimicrobial compounds

A cleaning composition for hard surfaces containing a polymeric compound comprising a main backbone derived from at least the following monomeric components: (I) 20 to 99.9% by weight of at least one cationic monomer according to formula (I) wherein Rand Rare, independently of one another, hydrogen or C-Calkyl; Rand Rare, independently of one another, hydrogen or alkyl, hydroxyalkyl, carboxyl alkyl, carboxyamide alkyl or alkoxyalkyl having from 1 to 18 carbon atoms; and Y represents an anion, and (II) 0.1 to 80% by weight of a hydrophobic unsaturated nonionic monomer that polymerizes in the presence of an initiator; optionally up to 60% by weight of a water-soluble monomer (III) which is different from either monomer (I) or monomer (II); and optionally reactant (IV), a crosslinking agent in an amount between 0 to 10% by weight, gives improved soil removal properties, antimicrobial and biofilm suppression properties as well as resistance to resoiling and staining. 

Hydrophobically modified cationic polymers and their use as cleaning aids

Anti-microbial compositions comprising certain imidazolium ionic liquids and non-ionic or anionic surfactants and methods of using said compositions in the preservation of personal care and cosmetic applications are provided.

Anti-microbial compositions

The instant invention relates to oligo- and poly-carbonates terminated with silicon containing groups which are useful as reducers of surface energy for organic materials such as polycarbonates, polyesters or polyketones or their mixtures, blends or alloys. Polymers with such reduced surface energy possess self-cleaning, anti-soiling, anti-graffiti, oil resistance, solvent resistance, chemical resistance, self-lubricating, scratch resistance, low moisture absorption, dirt pickup resistance, slip properties and a hydrophobic surface; and display anti-adhesion properties against proteins and against microorganisms such as for example, bacteria, fungi and algae.

A method is provided for the antimicrobial treatment of a surface which comprises the contacting a surface with substituted 4-aminopyrimidines.

4-aminopyrimidines and their use for the antimicrobial treatment of surfaces

The use of 2,4&#x2014;bis(alkylamino)pyrimidines of formula (1) Ris C-Calkyl or C-Claryl; Ris hydrogen or C-Calkyl; or Rand Rtogether form a radical of formula (1) R' and R&#x2033; are each independently of the other hydrogen, C-Calkyl or C-Calkoxy, Rand Rare each independently of the other hydrogen or C-Calkyl; Ris C-Calkyl, unsubstituted phenyl, C-Caryl, C-Caryl-C-Calkyl, hydroxy-C-Calkyl, di-C-Calkylamino-C-Calkyl, mono-C-Calkylamino-C-Calkyl, &#x2014;(CH)2-(O&#x2014;(CH))&#x2014;OH or &#x2014;(CH)&#x2014;(O&#x2014;(CH))&#x2014;NH; Ris C-Calkyl, C-Caryl, C-Caryl-C-Calkyl, hydroxy-C-Calkyl, di-CCalkylamino-C-Calkyl, mono- C-Calkylamino-C-Calkyl, &#x2014;(CH)&#x2014;(O&#x2014;(CH))&#x2014;OH or &#x2014;(CH)&#x2014;(O&#x2014;(CH))&#x2014;NH; or Rand Rand/or Rand R, together form a pyrrolidine, piperidine, hexamethyleneimine or morpholine ring; in the antimicrobial treatment of surfaces. 

Use of substitute 2,4-bis (alkylamino) pyrimidines or quinzolines as antimicrobials

Carboxylic acid ester derivatives of zosteric acid are effective in preventing biofouling and are readily formulated into coatings or films. Coating or film compositions of the esters, and methods for their application, are provided which reduce the dissolution of the esters into water or loss to the environment. The Zosteric acid esters of the invention appear to function by preventing adhesion of an organism to a surface rather than by acute toxic activity rendering said compositions more environmentally acceptable.

Carboxylic acid esters of zosteric acid for prevention of biofouling
