The present invention refers to a process for preserving an aqueous preparation of mineral material like e.g. calcium carbonate preparations, and to the use of a composition as a preservative in an aqueous preparation of mineral materials.

Process to preserve aqueous preparations of mineral materials, preserved aqueous preparations of mineral materials and use of preservative compounds in aqueous preparations of mineral materials

The invention relates to a surface-treated calcium carbonate for binding and bioremediating hydrocarbon-containing compositions, to a method for binding and bioremediating hydrocarbon-containing compositions as well as to the use of surface-treated calcium carbonate for binding and bioremediating hydrocarbon-containing compositions and to a composite material comprising the surface-treated calcium carbonate and a hydrocarbon-containing composition.

Surface-treated calcium carbonate for binding and bioremediating hydrocarbon-containing compositions

The present invention relates to carriers for the controlled release of active agents, comprising a core, comprising surface reacted natural or synthetic calcium carbonate, and at least one active agent, wherein said at least one active agent is associated with said natural or synthetic surface-reacted calcium carbonate, and wherein said surface-reacted natural or synthetic calcium carbonate is a reaction product of natural or synthetic calcium carbonate with carbon dioxide and one or more acids, wherein the carbon dioxide is formed in situ by the acid treatment and/or is supplied from an external source, and a coating encapsulating the core. It furthermore relates to the preparation of loaded carriers, as well as their use in different applications.

Coated controlled release active agent carriers

The present invention refers to a process for bacterial stabilizing aqueous preparations like e.g. calcium carbonate slurries and a composition which can be used for the biocidal treatment of such aqueous preparations.

Composition having biocide activity for aqueous preparations

This invention discloses a process for stabilizing an aqueous mineral preparation comprising a step of adding at least one aldehyde-containing and/or aldehyde-releasing and/or phenolic and/or isothiazoline biocide to said aqueous mineral preparation.

Process for bacterial stabilizing of aqueous ground natural calcium carbonate and/or precipitated calcium carbonate and/or dolomite and/or surface-reacted calcium carbonate-comprising mineral preparations

The invention concerns a process for disinfection and/or conservation and/or reduction and/or control of microbial contamination of aqueous dispersions and/or aqueous suspensions of mineral matter, providing satisfactory stability in terms of Brookfield&#x2122; viscosity for the said aqueous dispersions and/or suspensions of mineral matter. It also concerns the said aqueous dispersions and/or suspensions thus obtained, together with their uses in the mineral, paper and paint industries. Finally it concerns the end products obtained.

Method for controlling microbial contamination, mineral suspensions obtained and uses thereof

Process for control of microbial contamination, mineral suspensions obtained and their uses

The present invention relates to a process for stabilizing aqueous preparations of minerals by adding reuterin to the aqueous preparations, to the use of reuterin for the stabilization of such aqueous mineral preparations, and the aqueous mineral preparations containing reuterin.

Stabilisation of aqueous mineral preparations by reuterin

The present invention discloses an aqueous phenolates-containing liquid formulation having a solidification point of less than or equal to &#x2212;10&#xb0; C. which is characterized by comprising the following components:

Phenolate-containing formulation with low freezing point

The present invention discloses a process for quantitative and/or qualitative determination of the microbial contamination of suspensions, emulsions or dispersions containing minerals and/or pigments and/or fillers and/or fiber materials wherein following the addition of one or more substances which can be degraded by microorganisms, mixing and optionally subsequent incubation a sample of the suspensions, emulsions or dispersions is centrifuged to separate the microorganisms from the minerals and/or fillers and/or pigments and/or fiber materials and the number and/or size and/or type of the microorganisms is determined in the aqueous supernatant phase after one or more incubations.

Method for determining microbial contamination

The present invention relates to an aqueous formulation containing phenol and/or phenol derivatives having a low freezing point and anti-microbial activity.
