Talc is a platey white mineral
primarily consisting of natural magnesium silicate. The
numerous advantages of this inert mineral include high
oil and grease absorption (hydrophobic). Due to the
greasy feel, talc has been traditionally used as lubricant in
cosmetic creams and make up. The fragrance
retention capacity of talc makes it also ideal for deodorant sticks
and lotions.
