A stable matrix emulsion concentrate of a biocide, e.g. 3-iodopropynyl-2-butyl carbamate (IPBC) and/or a triazole fungicide, and stable aqueous and/or organic solvent formulations thereof, i.e. dilutable in water and/or an organic solvent are provided, which are particularly useful for treating wood products to provide protection against microorganisms and insects.

Stable matrix emulsion concentrates and stable aqueous and/or organic solvent compositions containing biocides

A stable, aqueous suspension concentrate which includes a solid polymeric dispersant comprising one or more anionic polymeric dispersing agents, optionally a co-dispersant which preferably is a homopolymer and/or a copolymer of a heterocyclic vinyl lactam, preferably in a wt. ratio of 0.1:1 to 1:0.1, a UV-labile, water-insoluble biocide active, and a UV-blocker or UV-absorber to stabilize said active upon storage and/or exposure to sunlight or UV radiation.

Stable aqueous suspension concentrate for delivery of UV-labile water-insoluble biocides

What is described herein is a neutral pH, VOC-free biocidal composition of 1,2-benzisothiazolin-3-one which is stable at low temperatures for an extended period of time. The compositions are particularly advantageous in use in protecting latex, paint, coating, cosmetic and personal care formulations against microbiological spoilage.

Stable, neutral pH, VOC-free biocidal compositions of 1,2-benzisothiazolin-3-one

This invention relates to a broad spectrum antimicrobial composition, effective against gram negative and gram positive bacteria and fungi, which comprises a synergistic composition comprising iodopropynyl butyl carbamate and a bicyclic hydroxymethyl oxazolidine containing less than 0.1% of free formaldehyde.

Antimicrobial oxazolidine/iodopropynyl-butyl carbamate composition containing less than 0.1wt% free formaldehyde

Stable, neutral pH VOC-free biocidal compositions of 1,2-benzisothiazolin-3-one

Liquid compositions consisting essentially of by weight, 0.1-50% IPBC in 99.9-50% polyethylene glycol, polypropylene glycol or polypropylene glycol glyceryl ester, or mixtures thereof, which do not contribute to the VOC of paints and coatings and is stabilized effectively against discoloration even at elevated temperatures or direct sunlight.

Liquid compositions of IPBC in polyethylene glycol, polypropylene glycol or polypropylene glycol glyceryl esters

A synergistic biocidal composition comprising a mixture of a formaldehyde adduct compound and 1,2-benzisothiazolin-3-one.
