Described herein is a synergistic preservative composition used for providing broad spectrum antimicrobial activity comprising: (i) about 0.1 wt. % to about 99.9 wt. % of propylene carbonate; (ii) about 0.1 wt. % to about 99.9 wt. % of one or more organic compounds selected from the group consisting of propanediol, capryl hydroxamic acid, and isopropyl methyl phenol; and (iii) about 0.1 wt. % to 99.0 wt. % of phenoxyethanol, a preservative compound, and wherein, the composition provides synergy having Synergy Index (SI) value of the total composition from about 0.05 to about 1.0. Also described is a process for preparing said synergistic preservative composition and method of using the same.

Synergistic preservative compositions, process for preparing the same and method of use thereof

What is described herein is a stable and reduced-yellowing/non-yellowing synergistic preservative composition comprising: (i) about 0.1 wt. % to about 40 wt. % of dehydroacetic acid (DHA); and about 0.1 wt. % to about 99.9 wt. % of at least one aprotic solvent. Also described herein are aqueous and non-aqueous based preservative compositions for various end-user applications, and processes for preparing and using such compositions to reduce yellowing of DHA when added to the end-user applications.

Synergistic compositions of dehydroacetic acid and methods for reducing yellowing in various end-user compositions

Described herein are multifunctional polymers comprising a first repeating unit having at least one pseudo-cationic moiety, a second repeating unit having at least a hydrophobic moiety, and a third repeating unit, where the weight-average molecular weight is less than about 10,000 Da. In one embodiment the polymers exhibit antimicrobial activity. Also provided are compositions formulated with the multifunctional polymers, and a method of providing antimicrobial activity.

Multifunctional polymers

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 synergistic matrix composite for making a stable microemulsion in water of an active ingredient comprising a first matrix composition including by wt. (a) 5-30% of a C-CN-alkyl pyrrolidone, (b) optionally, 5-60% of a water insoluble organic solvent soluble therein, (c) 30-70% of a non-ionic emulsifier, and (d) 1-15% of an EO/PO/EO copolymer, and, (e) optionally, 1-5% of a surface active buffering agent, e.g. a branched alkyl ethoxylated phosphate ester, a second matrix composition comprising a polar polymeric material, e.g. polyethylene glycol, and/or a neutralized derivatized vegetable oil, e.g. maleated linseed oil, which composite is capable of loading a higher amount of said active than either composition alone.

Synergistic matrix composite for making stable microemulsions of active ingredients

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

A synergistic biocidal composition comprising a mixture of 2-propenal polymer (APC) and 5-chloro-2-methyl-4-isothiazoline-3-one (CIT) and 2-methyl-4-isothiazoline-3-one (MIT).

Biocidal mixture of 2-propenal-releasing polymer and isothiazolones

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.
