Microemulsions gelled

The above mentioned effects suggest the possible use of S. sclarea oil in the stomatological field to treat infective conditions which are often accompanied by inflammation. Since anti-inflammatory and analgesic effects require some drug absorption, some research [56-57] has been done recently to evaluate the capacity of the essential oil components to permeate the oral mucous in various mucoadhesive formulations of the oil (microemulsions, hydrogels and gelled microemulsions), useful in local treatments of stomatological ailments. The permeation properties of the...

Clear antiperspirants have become popular because they leave no visible residue.They are not always formulated through a microemulsion route. Clear sticks can be based on dibenzylidene sorbitol acetal (DBSA) gelling agent and zirconium or glycine-complexed aluminum chlorhydrate antiperspirant actives that are soluble in propylene glycol without water. An alternative route is to closely match the refractive indices of the oil and water phases so a clear product (not a microemulsion) results for an antiperspirant gel [20,23]. Clear deodorant sticks with the active ingredient triclosan can be solidified with sodium stearate, which is incompatible with antiperspirant active ingredients (aluminium chlorhydrates).
