How is Nanotechnology Used in Personal Care Products?
Nanotechnology is employed in various ways to improve the performance of personal care products. Key applications include:
Sunscreens: Nanoparticles of zinc oxide and titanium dioxide are used to provide transparent UV protection without the white residue associated with larger particles. Anti-aging creams: Nanocapsules or liposomes can deliver active ingredients like retinol and peptides deeper into the skin. Hair care: Nanoparticles are used to improve the delivery of conditioning agents and to protect hair from environmental damage. Dental products: Nanoparticles of calcium phosphate or silver are used to enhance the effectiveness of toothpaste and mouthwashes.
