What are
Nanoparticles

Nanoparticles are small lipid vesicles in the range of nanometers (10^-9m). A nanometer is one billionth
of a meter,the width of six hydrogen atoms, or about 100,000th the size of a single grain of sand. The best way
to characterize them is to compare them with liposomes and emulsions. Liposomes and nanoparticles are
of comparable size. Both occur in the range from 20 to 1000 nm in diameter. Whereas liposomes are composed
of one or more bilayer membranes, nanoparticles are formed by a single layered shell.

Liposomes are filled with water and therefore are typical carriers for hydrophilic substances. On the other side, nanoparticles are filled with oil and lend themselves ideally as carriers for lipophilic agents or organic agents.The core of the nanoparticles can contain a wide variety of different cosmetic oils (pueraria mirifica extract) and lipophilic agents (vitamin A palmitate, vitamin E acetate, UV filters, and fragrance). The chemical stability of these ingredients (against oxidation) can be enhanced by their encapsulation into nanoparticles.
