Nanoparticles are being used for diverse purposes, from medical treatments, using in various branches of industry production such as solar and oxide fuel, batteries for energy storage, to wide incorporation into diverse materials of everyday use such as silver nanoparticles in cosmetics or clothes, optical devices, catalytic, bactericidal, electronic, sensor technology, biological labeling and treatment of some cancers. due to their exceptional properties including antibacterial activity, high resistance to oxidation and high thermal conductivity, nanoparticles have attracted considerable attention in recent years.
How are nanoparticles used in cosmetics?
Nanoparticles can be synthesized chemically or biologically. Metallic nanoparticles that have immense applications in industries are of different types, namely, Gold, Silver, Alloy, magnetic etc. This study aims to present an overview of nanoparticles, with special reference to their mechanism of biosynthesis and types. Metallic nanoparticles especially gold nanoparticles in cosmetics are used to either add more color and texture or to extend the durability and shelf life of various cosmetic products. If you are a cosmetics manufacturer or wholesaler looking for valuable information on this topic you can simply search of nanotechnology in cosmetics articles and use the data to expand your business.
What products have nanoparticles in them?
Acute dermal toxicity studies on silver nanoparticle (SNP) gel
formulation (S-gel) in Sprague-Dawley rats showed complete safety for topical
application. These results clearly indicate that silver nanoparticles could
provide a safer alternative to conventional antimicrobial agents in the form of
a topical antimicrobial formulation. Some special tooth creams for the neck of
sensitive teeth contain nano scale calcium phosphate (apatite) which produces a
thin layer similar to natural tooth enamel, which is thus supposed to reduce
sensitivity to pain. Tiny particles of nano meter-thin pigment can be found in
make-up, nanoparticulate gold and silver is used in certain day and night
creams to give the skin a fresher appearance. GNS Nanogistnanover TM Premium
make up range contains Nano silver, GNS NanogistnanoverTM Q10 Range contains
Nano silver. Nano silver is used in soaps, toothpastes, wet wipes, deodorants,
lip products, as well as face and body foams.
Nano silver containing
cleanser soap was claimed to have bactericidal and fungicidal properties and
was found useful in treating acne and sun damaged skin. To prevent transmission
of infectious diseases high efficacy within short exposure time, are important
parameters. Nanosilver in concentration of 15 mg per liter in hand wash was
found satisfying both parameters very effectively. Researchers have
discovered that silver nanoparticles can also be used to destroy yeasts such as
Candida glabrata and Candida albicans, which cause infections in mouth can be
killed by nano silver and therefore can be incorporated in dentifrices.
1. Use of nanotechnology in cosmetics is aimed to make fragrances last longer,
sunscreens more effective and anti-ageing creams.
2. To optimize manufacturing conditions for skin care formulation, a multi-component
system.
3. To prevent hair from turning grey and also for prevention of in treatment of hair loss
& used to preserve active ingredients, such as vitamins and anti-oxidants, and their
lightness and transparency.
4. To improve the UV protection in combination with organic sunscreens.
Biggest industrial consumers of nanoparticles
Nanoparticles have grown to become extremely important materials in various industries such as electronics, agriculture, automotive and cosmetics and most developed countries active in the mentioned sectors require nanoparticles as a major component in their production lines. To date the largest consumers of nanoparticles have been USA, China, Japan, South Korea, Germany, Canada and India but many countries are joining the trade since the products of nano technology are now being used in various other industries and countries are going to need them in larger proportions everyday.
As a result if any individual or company is looking for a dynamic and profitable trade to invest in, nanoparticles and especially those used in the cosmetics industry can be a proper candidate due to the expansion and diversity of the market in the years to come.
