A soft mineral composed of hydrated magnesium silicate, ground into powder for use in cosmetics, baby powder, and other applications.
From Arabic 'talq' through Medieval Latin 'talcum'. The Arabic word may derive from Persian, reflecting the ancient trade routes through which this valued mineral traveled from Asia to Europe.
Talcum's journey from ancient Persian mines to modern baby bottles reflects humanity's long relationship with this uniquely soft mineral. It's the softest mineral on the Mohs scale, rating just 1 out of 10, making it literally the gentlest rock you can touch.
Talcum powder was marketed to women for intimate hygiene and baby care via gendered advertising; the association created liability when studies linked talc to ovarian cancer, disproportionately affecting women's health.
Use factually when discussing talc safety; avoid gendered marketing language that implies women 'need' it for normalcy.
Women's health advocates forced transparency on talc safety; Johnson & Johnson faced lawsuits led by women demanding accountability for undisclosed risks.
