Popular questions
What is calamine lotion used for?
Calamine lotion (zinc oxide with a little ferric oxide) is used topically to relieve itching and mild skin irritation from bites, rashes, or poison ivy; this is different from E557 hemimorphite, a zinc silicate food anticaking agent.
What does calamine lotion do?
It soothes itching and irritation and helps dry oozing skin lesions via an astringent, protective barrier effect; this is not the same substance as E557 hemimorphite (zinc silicate) used in foods.
Can you leave calamine lotion on overnight?
Yes—on intact skin it’s generally fine to leave on for several hours or overnight, rinsing off if it over-dries or irritates; note this concerns calamine lotion, not E557 hemimorphite (a food additive).
Does calamine lotion expire?
Yes; check the bottle’s expiration date, as older product can separate or become less effective—replace if expired or if odor/texture changes; E557 hemimorphite is unrelated to this topical product.
Can you put calamine lotion on a dog?
Avoid unless a veterinarian advises—dogs may lick calamine (zinc oxide), and ingestion can be harmful; E557 hemimorphite is a food additive, not a veterinary topical.
What is kaolin clay?
Kaolin clay is a naturally occurring hydrated aluminium silicate mineral (mainly kaolinite), used as the food additive E559 (aluminium silicate). It’s a fine, white, inert powder formed by the weathering of feldspar-rich rocks.
What is kaolin used for?
In foods (as E559), it’s used mainly as an anti‑caking and release agent in powdered products and as a processing aid; outside foods, it’s widely used in ceramics, paper, rubber, and cosmetics.
Where is kaolin clay found?
It occurs worldwide in deposits formed by weathering of granite/feldspar; major sources include China (Gaoling), the southeastern United States (Georgia), the UK (Cornwall), and Brazil.
How much kaolin clay per pound of soap?
A common usage rate is about 0.5–1 teaspoon per pound of oils (roughly 1–3 g per 454 g), pre-dispersed in a little water or oil; higher amounts can make soap feel draggy or more drying.
Is kaolin clay good for skin?
Cosmetic‑grade kaolin is a mild, fine clay that can absorb excess oil and add slip, so it’s commonly used in masks and powders; it’s generally well tolerated, but overuse may be drying—patch test if you have very dry or sensitive skin.
