What Is Body Powder? | Uses, Talc Safety And Cornstarch Alternatives

Body powder is a loose personal-care product applied to skin to absorb moisture and reduce friction, often made with talc or cornstarch.

Whether it’s called baby powder, dusting powder, or a post-shower sprinkle, body powder has one job: keeping skin dry and comfortable. The main ingredients, how they work, and the safety questions around talc all factor into choosing a product—and knowing what you’re actually buying.

How Body Powder Works

Body powder works by absorbing sweat and moisture before it can cause friction. That’s why it gets used on hot days, after workouts, or anywhere skin rubs together.

By absorbing moisture, powder reduces the friction that leads to chafing. It also can help keep skin feeling smooth. This makes it popular for areas prone to sweating and rubbing, such as the thighs, underarms, and feet.

Some powders also help prevent caking and improve the feel of a product. Per government guidance, talc in personal care products can also be used to make a product opaque.

What Is Body Powder Made Of?

Body powder comes in a few different formulas, and the ingredient list drives both performance and safety.

• Talc: A naturally occurring mineral, chemically hydrous magnesium silicate. It absorbs moisture well and has been a common ingredient for decades.
• Cornstarch: A plant-based alternative that absorbs moisture effectively. It’s widely used in powders now marketed as talc-free.
• Baking soda: Added to neutralize odor in some formulas.
• Zinc oxide: Used for its skin-soothing properties.
• Fragrance and botanical extracts: Added for scent and skin feel.

If a product contains talc, the label may list it as talc, talcum powder, or magnesium silicate. Checking the label is the only way to know which type you’re holding.

The Safety Situation With Talc

Here’s the part that gets the most attention. The FDA states that published scientific literature since the 1960s has suggested a possible association between talc use in the genital area and ovarian cancer. It’s not a definitive link, but it’s a recurring finding that has shaped both litigation and consumer habits.

Health Canada takes a firmer stance. It says loose powder products such as baby powder, body powder, and loose face powder may be harmful to lungs if inhaled, and that talc products used in the genital area may cause ovarian cancer.

If this gives you pause, the route most people take is simple: a cornstarch-based powder. Health Canada identifies cornstarch-based powder as a talc-free alternative. It absorbs moisture similarly, and it sidesteps the talc-specific concerns entirely.

An independent panel convened by the FDA has also evaluated the safety of talc in everyday products to protect public health. The regulatory picture continues to evolve, so checking current guidance makes sense if you’re a regular user.

How To Use Body Powder Safely

The main caution for any loose powder is in the air. Health Canada notes that inhaled loose powder may be harmful to lungs, so the technique matters more than most people think.

Use less than you think you need. A small sprinkle goes further than a cloud.

Apply from a distance. Keep the bottle several inches from your skin so the powder settles instead of billowing.

Don’t breathe it in. Turn your head, hold your breath briefly, and let the powder settle before moving.

Focus on dry skin. Powder works best when applied to skin that’s already dry, not damp.

For genital-area use specifically, the FDA mentions the possible association with ovarian cancer and past guidance that raised questions about talc in that region. If that’s your use case, a cornstarch-based powder is the lower-risk choice.
