  • Publication number: 20200325344
    Abstract: This disclosure describes a process for producing a surface-modified calcium carbonate, the process comprising contacting a calcium carbonate or precursor thereof with at least one amphiphilic copolymer comprising hydrophilic subunits and hydrophobic subunits, in which the hydrophilic subunits derive from at least one ethylenically-unsaturated compound comprising a carboxylic acid group or salt or derivative thereof; the hydrophobic subunits derive from at least one ethylenically-unsaturated compound comprising a hydrophobic group; and the amphiphilic copolymer has a hydrophilic-lipophilic balance ranging from about 1 to about 40. Surface-modified calcium carbonates obtained from the process are also described, as well as compositions containing the surface-modified calcium carbonates.

  • Patent number: 10399862
    Abstract: A process for treating a sulfurous fluid to form gypsum and magnesium carbonate, whereby the sulfurous fluid is scrubbed with a sequestrating agent to yield a scrubbed fluid, gypsum and magnesium sulfate. The flue gas desulfurized gypsum is isolated from the magnesium sulfate solution by filtration or centrifugation. The magnesium sulfate is reacted with a carbonate salt to produce a magnesium carbonate whereby the reaction conditions are controlled to control the properties of the magnesium carbonate produced.

  • Publication number: 20190076340
    Abstract: A cosmetic composition that fluoresces when irradiated with electromagnetic energy is disclosed. The cosmetic composition may comprise a cosmetically accept medium comprising at least one inorganic compound, wherein the inorganic compound is doped with an inorganic fluorescence activator to cause the composition to emit a fluorescent response when irradiated with light, such as UV light. Related products that include such a composition are also disclosed, including a lip stick, an eyeliner, foundation, blush, body paint, a hair gel, or nail polish. There is also a method for imparting a fluorescent response to at least once keratinous surface of a person that comprises applying to the keratinous surface an effective amount of the composition described herein.

  • Publication number: 20190077964
    Abstract: Materials comprising minerals having modified surface properties, related methods, and their use in products. Materials for use in products may comprise a mineral and a carbonate, such as a precipitated calcium carbonate. Decorating the mineral with the precipitated calcium carbonate may modify a surface property of the mineral, such as, for example, absorptivity, reactivity, or fluorescence.

  • Publication number: 20180265370
    Abstract: A process for converting gypsum into precipitated calcium carbonate including reacting a mixture comprising gypsum and a seed, a mineral acid, or both with at least one carbonate source, whereby precipitated calcium carbonate is produced in the form of calcite and/or aragonite directly without conversion from a vaterite polymorph. Also, a process for converting gypsum into precipitated calcium carbonate including providing a mixture comprising i) gypsum ii) a seed, a mineral acid, or both iii) at least one additive selected from the group consisting of ammonium sulfate, an organic acid, or an iron material, and reacting the mixture with at least one carbonate source to produce precipitated calcium carbonate in the form of vaterite. The precipitated calcium carbonates having desired and unique compositions, polymorph and crystal size characteristics formed by these processes.

  • Publication number: 20170369329
    Abstract: A process for converting natural calcium carbonate into precipitated calcium carbonate, involving treating the natural calcium carbonate with a sulfate to produce a gypsum and reacting the gypsum with at least one carbonate source to produce precipitated calcium carbonate. The crystalline polymorph, particle size, and various other characteristics of the precipitated calcium carbonate are controlled by varying conditions during the reacting. Since the natural calcium carbonate is not calcined, the process relates to a low energy method of producing precipitated calcium carbonate of controlled polymorph and particle size with limestone, marble, or chalk as the calcium source.
