What is the use of talc in the preparation of camphor water? Powdered talc works as filter aid which renders the formulation clearer and also as distributing agent for the aromatic substances that ultimately increases the surface area of aromatic substances exposed to the solvent action of water. The distributing agents should be inert in nature.

In order to make talc more readily dispersible in an aqueous medium, it is contacted, in a finely divided form, with an aqueous solution of an alkali metal hydroxide or ammonium hydroxide, it is then washed with clean water, whereafter it is thermally dried to remove at least a substantial proportion of the water associated therewith. The talc thus treated can be suspended in water containing ...

In this paper, a TiO2/black talc composite photocatalyst was prepared by the sol-gel method using TBOT as titanium source and black talc as carrier. Rhodamine B was used as the targeted pollutant to study the adsorption role of carbon in black talc. The results showed that with the adsorption-degradation cycles, the illumination time can be reduced by 40%.

The effect of the addition of talc on the morphology and thermal properties of blends of thermoplastic polyurethane (TPU) and polypropylene (PP) was investigated. The blends of TPU and PP are incompatible because of large differences in polarities between the nonpolar crystalline PP and polar TPU and high interfacial tensions. The interaction between TPU and PP can be improved by using talc …

Talc is used cosmetically in talcum and baby powder as an adsorbent. Talc has been reported to be used in some food products, and is generally recognized as safe by the FDA. Natural talc contains asbestos, a substance that may lead to lung cancer. However, talcum products used in cosmetics have been free of asbestos since the 1970s.
