Know how to read labels
Have made a product
Better understand how to make product choices
What about nanoparticles in cosmetics?
Is it safe or more effective?
Or Is It Just A Marketing Strategy?
How does the consumer know it’s nano?
When are nano products better?
When do products use ‘nano’ in their labeling and marketing?
How Do We Make Informed Decisions? A new shampoo uses 'NANO' directly as its brand. Image: Courtesy imageshack.us The shampoo, claims to contain titanium dioxide (TiO 2 ) nanoparticles, which could penetrate more effectively into the hair and, thanks to its photocatalytic oxidation characteristics, oxidize the harmful residues after hair perming. Would you buy this shampoo?
