MICROZEST 25 Gardenia Blue
Microzest 25 Gardenia Blue is one of the additions to the Lessonia’s
pallet of natural pigments made out of micronised plants. This natural
pigment is extracted from the fruit of the Gardenia. Its blue colour is
due to a natural compound found in the fruits.
To increase the colouring power of the natural plant pigments,
Lessonia uses a micronising technology based on a very high speed
airflow. This technology works at cool temperature, does not heat the
organic molecules and keep them in their original shape and structure.
Its extremely fine particles size enables a dispersion or solubilisation in
numerous formulations, bringing a deep and intense natural blue
colour to the product.

GARDENIA : THE PLANT
Gardenia florida L. (or G.jasminoides Ellis) is known as Cape
Jasmine. It is a perennial plant originated from Asia and belonging to
the Rubiaceae family. It is a fragrant flowering evergreen tropical plant
which is commonly grown in Vietnam, Southern China, Taiwan and
Japan.
Evidence of Gardenia jasminoides in cultivation in China dates to the
Song Dinasty (960-1279 AD), where both wild and double-flowered
forms have been depicted in paintings Meanwhile, was first propagated
in England in August 1757 and sold well thereafter.
BENEFITS
Gardenias are widely used as exotic ornamental flowers in corsages,
as houseplants, and in some regions, as outdoor plants. A yellow silk
dye has been made for centuries from the chemical compound
acrocetin extracted from the gardenia berry. The blue pigments are
edible and are currently being used as a blue food colorant in East
Asia. Chinese herbal medicine, however, makes the most extensive
use of the gardenia. Its Chinese name is zhi zi. Numerous traditional
medicinal actions have been attributed to gardenia.

GENEPIN MOLECULAR STRUCTURE
The blue colour of the pigment extracted from the fruit of the gardenia
is due to genipin, an aglycone discovered in 1960 which turns blue
when combined with amino acids. Molecular formula : C11H14O5.

COLOURING ACTION
Lessonia micronises products to less than 25 microns
thanks to an exlusive micronisation technology.
It produces superfine materials by autogenous
comminution. The centrifugal movement of particles in the
chamber provides effective classification to control the
homogeneity of the particles size.
Thanks to its very fine particles, Microzest 25 Gardenia
Blue has numerous applications in cosmetics products
including loose and press powders, oily gels, emulsion
and water-based gels.
Microzest 25 Gardenia Blue is designed to present
maximum stability. However, unlike synthetic dyes, they
are made up of a complex group of natural molecules
which may react differently according to the ingredients
used in the finished products, the pH and the conditions
for use (light, temperature,etc.).
