Question

1. Consider the following statements –
1. Nano technology can be used in cosmetic sectors
2. Nanoparticles can be used as UV filter
3. Nano particles can be used as delivery vehicles
Select the correct codes

• A. Only 1
• B. Only 2 and 3
• C. Only 1 and 3
• D. All of the above

Answer 1

The correct option is D All of the above

1. The cosmetics industry is benefited with development of nanotechnologies. The applications of nanotechnology and nanomaterial are in numerous cosmetic products including moisturizers, hair care products, make up and sunscreen.
2. Nano-materials are being used in leading cosmetic products, most commonly as chemicals used to give the protection in sunscreens. In cosmetics field, there are mainly two uses for nanotechnology. The first is the use of nanoparticles as UV filters.
3. Titanium dioxide (TiO2) and Zinc Oxide (ZnO) are the main compounds used in these applications and organic alternatives to these have also been developed. The second use is nanotechnology for delivery. Liposomes and Niosomes are used in the cosmetic industry as delivery vehicles. Newer structures such as Solid Lipid Nanoparticles (SLN) and Nanostructured Lipid Carriers (NLC) have been found to be better performers than liposomes.
