Sarah is Skeptical:
I just read your post about talc causing cancer. You said it hasn`t been proven to be unsafe but I`m still not convinced. Therefore, I`m looking for products that use talc alternatives, like cornstarch. What do you think of cornstarch-based powders?

The Right Brain Gets Corny:
Cornstarch is a common ingredient in many powder-based formulations. Depending on what else is in the formula, it can be a good substitute for talc. The only problem with cornstarch is that it will absorb water much more easily than talc so products can cake and stick if they`re not formulated properly.

But the coolest thing about cornstarch is the way it changes its behavior when mixed with water. It forms a paste that flows like a liquid but if you quickly apply force to it, it acts like a solid. You have to see this to believe it, so watch this video. Some wacky students filled a swimming pool with a mix of cornstarch and water made on a concrete mixer truck. When stress is applied to the liquid it exhibits properties of a solid so they`re able to run across the top of it without sinking. But as soon as they stop running, they sink. Geeky? Yes, but very cool in a Beauty Brains kind of way!
