- Organic peroxides in liquid or solid form, are commonly used as polymerization initiators of ethylenically unsaturated monomers for the synthesis of various types of polymers.
- organic peroxides are most often highly unstable species because they decompose relatively easily under the action of a low input of heat, mechanical energy (friction or shock) or incompatible contaminants.
- certain organic peroxides can undergo a self-accelerated exothermic decomposition which can lead to fires and / or violent explosions.
- some of these organic peroxides can release combustible vapors capable of reacting with any source of ignition which can drastically increase or even accelerate the risk of violent explosion.
- the organic peroxides are in particular packaged in the form of aqueous emulsions comprising antifreeze.
- aqueous emulsions comprising antifreeze.
- the aqueous emulsions generally also contain an emulsifier having the advantage of lowering the interfacial tension between the aqueous phase and the organic peroxide in order to facilitate its dispersion in the form of droplets and to maintain the size of the latter over time.

These handling steps must be carried out as quickly as possible. To do this, it is important that the peroxide emulsion has a low viscosity so that the flow of the emulsion is facilitated as much as possible.

- the average droplet size is at least twice as large in the case of composition Al than in the case of compositions according to the invention B and C.
- the average droplet size and the maximum droplet size are much greater in the case of composition A2 than in the case of compositions B and C.
- the average size of the droplets and the maximum size of the droplets in the comparative composition A3 are greater than those of the compositions according to the invention B and C.
- a demixing of the emulsion A3 is observed from the 5th month while the average and maximum size of the droplets remain low in the case of the compositions according to the invention B and C.
- compositions according to the invention B and C are more stable on storage over the same period of time of six months than the comparative compositions A1, A2 and A3 because the average size as well as the maximum size of the droplets evolve much more slowly.
- the droplets of organic peroxides migrate, that is to say sediment, more towards the bottom of the aqueous phase than in the case of the compositions according to the invention B and C.
- the dispersion of the droplets of organic peroxides in the aqueous phase is more homogeneous in the case of the compositions according to the invention B and C, and the initial proportions of each of the organic peroxides are well respected.
- composition D was prepared according to the same procedure as that described in Example 1.
- composition D the weight ratio between the di-sec-butyl peroxydicarbonate and the di (2-ethylhexyl) peroxydicarbonate is 20/80.
- the average droplet size and the maximum droplet size are measured according to the protocol described in Example 1.
