Delaminated transparent talc
 A delaminated talc has a plurality of high aspect ratio, smooth surface particles. The aspect ratio of the particles is determined by dividing their extent along an upper surface thereof by their thickness. The upper surface is substantially parallel to the lamellar interface direction and the thickness is measured perpendicularly to the interface direction. The upper, lower and side surfaces of the particles are smooth, lacking acute angularity and staircase effect which give rise to increased coefficient of friction and light scattering. The talc is especially suitable in cosmetic and pharmacologic preparations due to its high degree of transparency, skin adhesiveness, lubricity and spreadability.
