Wax and 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

Our services for wax and waxy products

Characterization of the physical and thermal properties of wax and waxy products

Melting point, melt viscosity, rheological behavior, crystallization.

Interaction analysis

with solvents, polymers, oils and other additives.

Study of transitions and transformations

Melting, solidification, mixing, emulsification.

Optimization of formulations

combining waxes and complex matrices (cosmetics, candles, coatings, polymers).

Industrial support

Adaptation of mixing, molding, extrusion or deposition processes.

Advice and training for waxing

for an in-depth understanding of the physicochemical mechanisms specific to waxes.

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.
