What can nanotechnology be used for?

Nanotechnology is helping to considerably improve, even revolutionize, many technology and industry sectors: information technology, homeland security, medicine, transportation, energy, food safety, and environmental science, among many others.

What are the benefits of nanoparticles in cosmetics?

Nanotechnology incorporation in cosmetic formulation is considered as the hottest and emerging technology available. Cosmetic manufacturers use nanoscale size ingredients to provide better UV protection, deeper skin penetration, long-lasting effects, increased color, finish quality, and many more.

How has nanotechnology made the product more effective?

Nanoscale materials exhibit different properties and advantages compared to the larger-scale original material. Nano ingredients make products more efficient while enhancing consumer acceptance. Nano emulsions are transparent and have unique skin feel. They stabilize the actives and improve efficacy.

Which cosmetic companies use nanotechnology?

Other companies using nanotech in their skin products as of 2005 include: Mary Kay and Clinique from Lauder; Neutrogena, from Johnson & Johnson; Avon; and the Estee Lauder brand. Hair products – using nanoemulsions to encapsulate active ingredients and carry them deeper into hair shafts.

Which cosmetics contain nanoparticles?

Nanoparticles alter properties of cosmetic products including color, transparency, solubility and chemical reactivity. It is unclear to what extent insoluble nanoparticles are used in cosmetic products. FOUND IN: deodorants, toothpastes, shampoos, lotions, foundation, anti-aging creams, and nail polish.

Are lipid nanoparticles harmful?

PLGA nanoparticles have been proven to be safe. Toxicity assays have been undertaken in Balb/C mice, which showed no altertaions in the histopathlogy or tissue damage. However, bio distribution and retention studies, following oral administration of PLGA nanoparticles showed 40% particles accumulation in liver [91].

Is nanotechnology in cosmetics safe?

In humans, they have been linked with liver damage and may even affect the immune system. In summary, nanoparticles in cosmetics & skincare appear to be very dangerous, and so consumers should educate themselves as to which products contain these particles and which do not.

What foods have nanoparticles in them?

The most common protein nanoparticles found in foods are the casein micelles found in bovine milk and other dairy products, which are small clusters of casein molecules and calcium phosphate ions.

What drugs contain lipid nanoparticles?

For example, the earliest approved liposomal drug was Doxil, a lipid nanoparticle formulation of the antitumor agent doxorubicin, which is used to treat ovarian cancer. (6) Another liposomal drug, Epaxal, is a lipid nanoparticle formulation of a protein antigen used as a hepatitis vaccine.
