The microencapsulation process
Microencapsulation is a process whereby a substance in an extreme
state of comminution ie ultrafine capsules or beads, is enclosed
by a protective skin, from which the substance is released by
impact, solution, heat or other mechanism.
The microencapsulation of active ingredients is a developing technology
being used for a variety of applications.
e.g.
 to protect
active ingredients from hostile environments
to provide
delayed release
The most commonplace example of the use of microencapsulation
is the 'scratch and sniff' perfume strips whereby finely dispersed
droplets of perfume are encapsulated within a protective shell
which prevents evaporation until the capsules are broken by applying
pressure.
Microencapsulation techniques.
Viesage has developed microencapsulation techniques. Such techniques
are axiomatically related to the active. Thus, the selection of
the microencapsulation system has to be individually tailored
to satisfy the chemistry of the active ingredient and the system
or process into which the product is to be applied.
Viesage encapsulation technology has been used successfully to
encapsulate:
Sunscreen actives
to enhance performance within skin care products
Fragrances
used in 'wet wipe' personal care products
Viesage offer a consultancy service to meet individual microencapsulation
requirements.
