Excipients for liquid forms

Syrups, Solutions, Liquid ampoules, Dispersions, Semi-solids, Softgels
Sweeteners
Polyols are sugarless bulk sweeteners that can be used as total substitutes for sucrose and meet organoleptic (sweetening power) and dietetic requirements (sugar-free, low-calorie, do not induce dental caries, may be advised for diabetics). 
Roquette’s range of liquid polyols include the most wide-ranging NEOSORB® liquid sorbitol solutions and LYCASIN® liquid maltitol solutions with varying sweetness and viscosity profiles.
Roquette also proposes conventional glucose syrups sweeteners for liquid forms.
 
Buffering
Buffers are used to stabilize the pH of liquid formulations. Roquette has developed natural, physiological buffering agents based on sodium gluconate.

Encapsulation
The formation of molecular inclusion complexes with cyclodextrins has become an accepted formulation strategy to improve the solubility or stability of active ingredients and can also be used to improve the taste of bitter or unpleasant drugs. 

ROQUETTE has pioneered the development of betacyclodextrin technology leading to a full range of KLEPTOSE® betacyclodextrins, with different powder properties, chemical substitution or solubility profile to suit modern formulation needs:
