Viscosity	You should know the knowledge about viscosity ratio of the formulation and the planning design. Remember if your formulation is composed of higher viscosity agents or the percentage, it can affect the atomizing effects of the spray. The material can be difficult to spray or move forward if it is more viscous. Moreover, if the size of the droplet is bigger and the spray plume is shorter, it directly impacts the nasal spray delivery. Hence your formulation viscosity percentage should be optimized to allow an easy facilitation of the formulation whenever you require to administer it inside your nostril.
Surface tension	If your formulation is with lesser surface tension, then it becomes easier for you to spray and atomize the product. It means that if the size of the droplet of oxymetazoline hydrochloride nasal spray is smaller, it allows the easier flow with expanded spray pressure. You need to remember that your droplet size should not be higher than 10 µm. For that, various solvents and co-solvents are used but you need to monitor the balance ratio among density and viscosity.
Density	The density which is defined as mass per unit volume, also has a similar effect to viscosity and surface tension. If the density of the formulation or the product you are designing is higher it will make your preparation difficult to move out or it affects the atomizing effect of the spray. So, it should be less so that effects on the spray and their circulation inside the body would be better.
Particles	The particle size also has a direct relationship with the atomizing property of the oxymetazoline hydrochloride nasal spray. Therefore, every manufacturer must be keeping account that the particle size of the solution must be smaller. For this purpose, further milling and micronization of the ingredients must be carried out.
