The talc particles are microcrystalline talc.
The nano-talc powder provided by the invention is a novel hydrophilic talc composition.
The nano-talc powder provided by the invention is a novel hydrophilic talc composition also of the invention.
A deaerated talc product may include a micronized talc powder, and a bag containing the deaerated talc.
The invention relates to the use of talcum, or products containing talcum as additives in the manufacture of paper.
The invention provides a more economical and environmentally friendlier use of talcum, or products containing talcum.
It is also proposed to use talcum-filled Polystyrol.
Some, but not all, baby powders are talcum powder, made with talc.
Some, but not all, baby powders are talcum powders prepared with the talc.
Talc is found in talcum powder, baby powder and makeup.
A cosmetic composition includes talc or a talc substitute, mica, and iron oxide.
The present invention relates also to talc slurry.
The invention relates to the method of producing said talc slurry.
For talc is used finely divided, powdery talc or granulated talc having average grain size 5 νm at maximum.

The soaking method comprises dry milling talc powder followed by mixing with water and soaking to provide high surface area nano talc slurry.
After grinding, rough flotation is performed on minerals that float naturally, such as talc, into what is termed rough talc concentrate, which is then stored.
The use of talc as a nucleating agent is beneficial, and in the method according to the invention the talc concentration proves to be a determining factor for the mean foam-cell diameter.
The composition may further include a material such as talc.
The talc is selected from those which do not significantly reduce the electrical strength of the laminate relative to those which contain no talc particles.
More specifically, the invention relates to crop protection compositions utilizing talc and one or more additives providing for improved aqueous suspension of the talc and methods for making such compositions.
In one embodiment, the mineral filler is talc.
The present invention also discloses horticultural substrates coated with a crop protective composition utilizing talc and one or more additives providing for improved aqueous suspension of the talc.
