What are Nanoemulsions?
Nanoemulsions can be defined as oil-in-water (o/w) emulsions
with mean droplet diameters ranging from 50 to 1000 nm.
Usually, the average droplet size is between 100 and 500 nm.
The terms sub-micron emulsion (SME) and mini-emulsion are
used as synonyms. Emulsions which match this definition have
been used in parenteral nutrition for a long time. Usually, SMEs
contain 10 to 20 per cent oil stabilized with 0.5 to 2 per cent
egg or soybean lecithin
What are the Benefits of Using Nanoemulsions in Skincare
Products?
Due to their lipohilic interior, nanoemulsions are more suitable
for the transport of lipophilic compounds than liposomes.
Similar to liposomes, they support the skin penetration of
active ingredients and thus increase their concentration in the
skin. Furthermore, nanoemulsions gain increasing interest due
to their own bioactive effects. Nanoemulsions are able to favor
the transport of suitable lipids into the skin. This may reduce
the transepidermal water loss (TEWL), indicating that the
barrier function of the skin is strengthened.
