Wax-based products: understand, master, innovate

At Rheonis, we support manufacturers in understanding and optimizing wax products — whether pure formulations, wax-polymer blends, or complex systems integrating fillers and additives.

The challenges of wax-based products

• Anticipate thermal behaviors : know precisely the temperatures and profiles of melting, crystallization and solidification.
• Optimize texture and stability : adjust hardness, plasticity, firmness for homogeneous cosmetic or pharmaceutical products.
• Improve processability : understand the rheology of molten waxes for molding, extrusion, coating.
• Reduce production defects : limit problems of flowability, cracks, incompatibilities or appearance defects.
• Accelerate development more durable and differentiating solid formulations.

 A wide variety of waxes and applications

We process all types of waxes and wax formulations:

• Wax types : natural (beeswax, carnauba, candelilla), mineral (paraffins, microcrystalline), synthetic (Fischer-Tropsch, polyolefins, esters, silicones, etc.)
• Forms and formulations : sticks, balms, pastes, gels, dispersions, oily, resinous or solvent systems
• Finished products :
  • Cosmetics : lipsticks, balms, mascaras, deodorants…
  • Agri-food : fruit coatings, chocolates, waxed packaging
  • Pharmaceuticals : suppositories, medical sticks
  • Industry & materials : solid lubricants, release waxes, protective agents, surface films

Industrial processes concerned

Wax-based products are used in many processes:

• Molding, extrusion and injection (cosmetics, packaging, composites).
• Coating and coating (food, pharmaceutical, paper-cardboard).
• Granulation and compaction (solid formulations, tablets, lozenges).
• Mixing and stirring (complex wax formulations, wax-oil emulsions).

Measurements and analyses adapted to waxes

Rheonis provides a range of multi-physical measurements to characterize and understand wax-based products:

• State change measurements : fusion, crystallization, polymorphism, solid-liquid transition.
• Rheological measurements : melt viscosity, viscoelastic behavior, yield threshold.
• Mechanical measurements : hardness, compression, creep, mechanical strength.
• Structural measures : crystallinity, internal organization, possible porosity.
• Tribological measurements : friction, sliding and sensory properties on contact.
• Texture measurements : textural profile, firmness, plasticity.
