Rhinoial® works because while sodium chloride creates a slightly osmotic environment that attracts water, therefore thinning the mucus and facilitating its elimination, aloe leaf juice polysaccharides create a hydrated, humectant and emollient film that soothes the irritated mucosa. Moreover, sodium hyaluronate, a hydrating substance, creates a mucoprotective, hydrating film on the damaged mucosa. This film persists on the mucosa due to the natural mucoadhesiveness of hydrated high-molecular-weight hyaluronate, which has been further enhanced by adding glycerophosphocholine to give a really long-lasting hydrating and protective effect.
