Applications：
As an expectorant, it is suitable for patients with viscous sputum that is difficult to cough up, as it can reduce the surface tension of sputum and lower its viscosity. It can also be used as a pharmaceutical excipient, functioning as a solubilizer and bacteriostatic agent, and is applied in contact lens and orthokeratology (OK) lens care solutions, eye drops, ear drops, etc. It is suitable for pharmaceutical preparations such as tobramycin eye drops, tobramycin and dexamethasone eye drops, and cyclosporine eye drops.
