Anybody know why it's good for poison ivy? Relationship to zinc oxide?

"Calamine is a mixture of zinc oxide (ZnO) with about 0.5% iron(III) oxide (Fe2O3)."

[edit] pink

What gives Calamine Lotion that characteristic pink color?-69.87.203.67 00:53, 27 April 2007 (UTC)

The iron (rust) seems to be included just to give the pinkish hue. Why is it there? Who first put iron in? When? Which ingredients, if any, actually have anti-itch characteristics? When was this discovered?-69.87.204.36 12:41, 27 April 2007 (UTC)

[edit] Bentonite magma

"...calamine lotion, are suspensions for external use only. Magmas and milks are thick, viscous, aqueous suspensions of insoluble inorganic compounds; the particle size is usually larger than in gels. Bentonite magma, for example, is produced by hydration of bentonite, a colloidal hydrated aluminum silicate, and is used as a suspending agent, as, for example, in calamine lotion. Milk (cream) of..." [1]

"Calamine Lotion: Experimenting with a New Suspending Agent
The use of a new suspending agent is investigated. Calamine lotion, USP contains bentonite magma as a suspending agent. In this study, bentonite magma was partially or completely replaced with a new suspending agent called tahini. Tahini is sesame paste composed of crushed sesame seeds in sesame oil... Overall, the use of tahini in calamine lotion has improved the physical stability of the formula." [2]

The standard lotion is labelled "shake well", and really does need shaking -- the suspension does not seem to work very well, and seems to separate out again after just a few minutes.-69.87.204.36 12:41, 27 April 2007 (UTC)
