collodion

; flexible collodion BP occlusive topical paint acting as a vehicle for an active ingredient (e.g. ichthammol or 12% salicylic acid); see Table 1
Table 1: Vehicles used to carry active ingredients for topical use in skin conditions
Vehicle typeComment
ApplicationsViscous solutions, emulsions or suspensions for application to the skin or nails
CollodionsClear paints carrying an active ingredient applied to the skin and left to dry to a flexible film (e.g. ichthammol in collodion)
CreamsEmulsions of oil and water generally well absorbed into the skin surface; creams are less greasy and easier to apply than ointments
GelsActive ingredients within a suitable hydrophilic or hydrophobic base; they have a high water content
LotionsA cooling preparation for external application, to the skin, formed as a liquid suspension often in an industrial methylated spirit or alcohol base
A shake lotion contains an insoluble powder in a liquid that must be shaken before use to disperse the powder evenly throughout the liquid medium, e.g. calamine lotion
OintmentsGreasy preparations that are usually insoluble in water; a salve or unguent; a semisolid preparation containing a medicinal agent in a fatty or waxy base, intended for topical application; the greasy base of an ointment (usually formulated from soft paraffin, or a combination of soft and hard paraffin) acts as an occlusive medium and makes it especially suitable for use on dry or anhydrous skin
Water-soluble ointments are based on macrogols and can be washed off
PastesStiff preparations containing a high proportion of fine solids, such as zinc oxide and starch; they are less occlusive than ointments and can be used to protect lichenified, inflamed or excoriated skin (e.g. in eczema)
Dusting powdersFine powders, e.g. talc, applied to apposing skin surfaces; they should not be used on moist or weeping surfaces
