Context: Talcum powder is a popular daily use cosmetic product in India with a high urban and rural penetration. Aim: To examine the photoprotective ability of a popular brand of talcum powder. Design: Nonrandomized controlled efficacy study. Subjects and Methods: Minimal erythema dose (MED) following narrowband ultraviolet B irradiation among ten volunteers was recorded. Sun protection factor (SPF) of talcum powder was determined by standard in vivo method. Percentages of zinc oxide in the test sample and ten other commercially available brands of talcum powder were estimated by atomic absorption spectrophotometry. Statistical Analysis Used: Calculation of mean. Results: The mean MED of volunteers was 310 milli Joule (mJ) without talcum powder and 400 mJ with talcum powder. The mean SPF of talcum powder was 1.29. The percentage of zinc oxide in the test sample was estimated to be 1.5%. Conclusions: Talcum powder offers low photoprotection due to low zinc oxide content.
