Talc Is A Dangerous Ingredient In Condoms For Women: Have you ever opened a condom and noticed a small dust of powder come out? That powder is talc, a dangerous ingredient some manufacturers use in the production of condoms. Particles of talc powder in latex condoms can enter a girl’s body during s*x and irritate tissues, potentially causing infertility (not able to have a baby), and cancer. To reduce these risks of infertility and potential cancer, use non-latex condoms when having s*x.
