Practically all original and review papers on nano-emulsions stress their great potential for applications. However, after more
than 10 years since a growing interest in nano-emulsions was developed, reports on direct applications of nano-emulsions
are not as numerous as expected. The main limitation for developing
applications for nano-emulsions is their stability.
Although practically all papers on nano-emulsions indicate
that nano-emulsions can be stable even by years, the small
