STORY TELLING
The partners of this multi-resonance physical emulsion project began this adventure during a study granted by the French Ministry of Defense (DGA) for the decontamination of RAFALE fighters. The new technologies and materials used in such modern aircraft require the use of decontaminants at low pressure and with less aggressive formulations than the Sodium Hypochlorite used at high pressure and high temperature until the end of the 20th century. .The process of decontamination with fine foam application showed during the tests on real military contaminants (Chemical and Nuclear), a surprising effectiveness compared to the quantity of material and water used.
The causes of the effectiveness of this foam decontamination were not immediately identified since scientific reasoning usually considers the activity of active ingredients as a function of temperature and concentration. The activity of the foam being itself associated with its expansion and its density for a given concentration of active product.
We discovered by chance in 2016, the ability of this system to produce mini-emulsions. Securengy has been working since its creation on the understanding and physical model of this process. Its reproducibility is now part of a know-how based on scientific bases (initial spectral analysis of single-phase compositions) and determination by calculation of the resonance modes which allows the dimensioning of the reactor and other coupling parameters.
These studies allowed us to highlight new reproducible phenomena such as the polarization of the droplets, obtained by the determination of specific parameters on the production system.
STABILITY & LIFE TIME
Our first long term stable emulsions were made in December 2017: they were made only with osmosis water and sunflower oil (massage quality).
This simple formulation of 5% sunflower oil in water was made without adjuvants or surfactants.
It remained stable in transparent glass or polyethylene vials, its stability being degraded by contact with impurities or chemicals.
The use of voltage-actives or surfactants greatly reduces the lifetime and increases the size of the droplets.
STABILITY IN TEMPERATURE
This first prototyped emulsion, stable for more than 4 years has been stored at indoor room temperature and in the refrigerator with a similar conservation. The stability limits of our mini-emulsion correspond to those defining the couplings between the different constituents: - the emulsion is destroyed by freezing which modifies the structure of the intermolecular bonds of water; - the emulsion is destroyed locally by excessively high temperatures (typically more than 70°C and in a variable manner depending on the formulations)
THEORITICAL ASPECTS
The stabilization is carried out by a physical process which achieves a balance or harmonic coupling within each droplet between the oscillatory modes of the volume and the surface of the droplet with the harmonic oscillators of the atoms, molecules and intermolecular bonds of their constituents.
These harmonic couplings are only possible for droplet sizes below 15 microns and correspond:
- to spheroidal shapes only
- at calibrated droplet sizes in determined ranges, the different droplet sizes corresponding to harmonics of the oscillators.
BIO-AVAILABILITY
Typically a skin pore is about 15 micrometers in diameter.
The droplets of our mini-emulsions have sizes that remain below this dimension. In addition, for a polarized emulsion, the penetration of the pores can be improved.
The result has multiple benefits:
- the active principle penetrating more quickly, the products require a lower % for the same result;
- no residual greasy film for concentrations below 10%
- the action of the mini-emulsion becomes close to that obtained with alcoholic solutions.
AQUOUS &OILY PHASES COMPOSITION
We carry out the study of the mini-emulsion device from the aqueous and oily phases that you provide to us. Each of the phases can contain several active principles and several flavors which will remain unchanged in the final emulsion. It is however possible to have migrations from one phase to another of certain principles. For polarized and non-micellar emulsions, it is possible to have phases which contain products which are normally incompatible because they are reactive.
CONFORMATION
The adjustments of some parameters of the production machine lead to a polarization of the drops or clusters which gives it a dynamic behavior, each drop being repelled and simultaneously attracted by its neighbors in the three dimensions. This optional conformation corresponds to the adjustment of known parameters of the production machine according to the formulation constituents . This first form (dynamic) has a milky appearance and has improved penetration characteristics. It is ideal for spraying active ingredients whose penetration is desired over a large surface. Another adjustment of the parameters of the machine makes it possible to obtain a conformation of the micelle type (aqueous phase inside and oily external layer), this second form has a translucent aspect with the same color of oil, but loses in immediate bioavailability performance. The mixing of this micro-emulsion with compatible liquid media is possible in some cases and must be studied on the basis of specifications.
PROCESSES
Stabilization is carried out by a physical multi-resonance process initiated within a reactor of specific dimensions made for your formulation.
These resonances are self-maintained over a very long period with regard to the size of the "living" cells that are the clusters or droplets. All of these resonances are coupled and the overall stability relates to a balance between the droplets through interferences of various kinds that remain to be discovered.
Such processes could be implemented for a specific machine in order to produce large quantities of stable emulsion or integrated in a motor subsystem for immediate dispersion and combustion.
