Roquette excipients for liquid solutions

Roquette offers a large range of plant-based excipients for the formulation of liquid forms: syrups, solutions, ampoules, dispersions, etc.

Bulk sweeteners

Polyols are sugarless bulk sweeteners that can be used as total substitutes for sucrose and meet organoleptic and dietetic requirements (sweetening power, sugar-free, low-calorie, do not induce dental caries, may be advised for diabetics).

Roquette’s vast range of liquid polyols include liquid sorbitols and maltitols with varying sweetness and viscosity profiles:
  • NEOSORB® liquid sorbitol
  • LYCASIN® liquid maltitol

Roquette also offers conventional glucose syrups sweeteners for liquid forms.


Buffers are used to stabilize the pH of liquid formulations. Roquette has developed natural, physiological buffering agents based on sodium gluconate.

Suspensions agents

TABULOSE® SC is a co-processed product composed of Microcrystalline Cellulose (MCC) and Sodium Carboxymethylcellulose (CMC), which makes a thixotropic suspension used as a secondary stabilizer and suspension agent in semi-solid formulas such as suspensions, emulsions, aerosols, creams, lotions and gels.

Syrup formulation - How can ROQUETTE assist you in your product developments?

Formulating a syrup is not always straightforward. Many parameters have to be managed in combination with the active ingredients including pH, colour stability, precipitation, suspension and separation, crystallization and cap-locking. With the support of our application laboratories, the Roquette Pharma team is ready to assist with the development or optimization of your syrup formulations.
