Excipients For Liquid Forms

Bulk sweeteners, anti-oxidants and organic buffers.

Bulk sweeteners

Polyols are sugarless 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 syrups with varying sweetness and viscosity profiles.

Roquette also proposes conventional glucose syrups sweeteners for liquid forms.

Anti-oxidants

In liquid preparations oxidation might result in the development of undesirable flavors and discoloration. The addition of a water-soluble anti-oxidant such as Roquette’s Sodium Erythorbate avoids these side reactions. Sodium Erythorbate has the same anti-oxidant properties as sodium ascorbate but has no vitamin activity.

Organic buffers

Buffers are used to stabilise the pH of liquid formulations. Roquette has developed a range of natural, physiological buffers based on gluconic acid (lactone), sodium gluconate.
