Sorbitol and hypromellose formulations
Otrivin Moisturising Adult and Otrivin Moisturising Paediatric nasal solutions are formulated with sorbitol and Hypromellose
Sorbitol and hypromellose, when combined with other active ingredients in a nasal spray or drops, soothe and moisturise dry and irritated nasal passageways.1,2
Sorbitol and hypromellose complement the action of decongestants
The addition of sorbitol and hypromellose to Otrivin Moisturising nasal drops provides a supportive effect to the active decongestant ingredient by:
- Restoring moisture to the nasal mucosa1
Sorbitol and hypromellose counteract dryness from topical vasoconstrictors6
Unlike alternative nasal decongestants, formulations that contain hypromellose and sorbitol are found to have a higher water-retaining capability, significant moisturising properties and the ability to counteract dryness.6

Sorbitol is a humectant with potent hygroscopic properties1
Sorbitol is a naturally occurring alcohol, but may also be synthesized from glucose.3 It possesses humectant properties with the ability to moisturise the nasal mucosa, and may also be used as a topical emulsion in low concentrations.1
Hypromellose is an inert viscoelastic polymer that can be used as an emulsifying agent, bio-adhesive, and thickening agent1,4
Hypromellose is widely used as a suspending and thickening agent for topical formulations in pharmaceuticals.1 Its ability to absorb moisture from the atmosphere also allows it to function as a humectant.1 As the surface properties of hypromellose provide reduced surface tension and increased viscosity,4 it may offer some barrier protection to the nasal mucosa.4,5
