Abstract: A method of reducing undesirable microorganism concentration, the method comprises (a) introducing a quantity of fermentable carbohydrate to an aqueous system, (b) introducing a quantity of desirable microorganism to the aqueous system, (c) introducing a hops acid extract into the aqueous system and (d) introducing nisin into the aqueous system.

Abstract: The invention relates to an aqueous cleansing emulsion comprising a hydrophobic component H1 selected from the group consisting of the following categories: (i) aliphatic C10- or C15-terpene hydrocarbons; (ii) aliphatic C10- or C15-terpenoids; (iii) aliphatic C15-C40-hydrocarbons; and (iv) C6-C30-carboxylic acid C1-C30-alkyl esters. A hydrophobic component H2 selected from the group consisting of the following categories: (iii) aliphatic C15-C40-hydrocarbons; (iv) C6-C30-carboxylic acid C1-C30-alkyl esters; (v) aliphatic C6-C19-hydrocarbons; (vi) aromatic C10- or C15-terpenoids; (vii) aliphatic or aromatic C20-, C25-, C30- or C35-terpenoids; (viii) essential, animal or vegetable oils; and (ix) silicon oils. Furthermore, the emulsion contains an emulsifier E1 having a HLB value of 4±2; an emulsifier E2 having a HLB value of 9±2; and optionally, an emulsifier E3 having an HLB value of 16±4.

Abstract: The invention relates to novel, stable bi-molecular cationic inverse emulsion polymers (W/O) with both different molecular weights and cationic activities that are assembled via an “in situ” emulsion polymerization of a high molecular weight cationic polymer in the presence of a low molecular weight polymer in the aqueous phase. The low molecular cationic polymer is produced in a pre-polymerization in solution. The novel, stable cationic water-in-oil emulsion is easy invertible and useful as flocculant, dewatering aid and retention aid in papermaking.

Abstract: The invention relates to water-in-water polymer dispersions containing cross-linked cationic polymers, methods for their preparation and their use. The water-in-water polymer dispersions are useful inter alia as flocculants, dewatering (drainage) aids and retention aids in papermaking.

Abstract: The present invention relates to water-in-water polymer dispersions containing cross-linked anionic polymers, methods for their preparation and their use. The water-in-water polymer dispersions are useful inter alia as flocculants, dewatering (drainage) aids and retention aids in papermaking.
