It is considered to be safe in pregnancy. [4] Calamine is a combination of zinc oxide and 0.5% ferric oxide (Fe 2 O 3). [6] The lotion is produced with additional ingredients such as phenol and calcium hydroxide. [6] [7] The use of calamine lotion dates back as far as 1500 BC. [8] It is on the World Health Organization's List of Essential ...
Zinc oxide is an inorganic compound with the formula Zn O.It is a white powder which is insoluble in water. ZnO is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, [12] paints, sunscreens, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, semi conductors ...
Zinc has been popularly used as zinc gluconate or zinc acetate lozenges for treating the common cold, [12] and therefore the safety of usage at about 100 mg/day level is a relevant question. Unlike iron , the elimination of zinc is concentration-dependent.
Zinc oxide-based ointments are a much safer alternative. [17] Soapstone (massive talc) is often used as a marker for welding or metalworking. [18] [19] Talc is also used as food additive or in pharmaceutical products as a glidant. In medicine, talc is used as a pleurodesis agent to prevent recurrent pleural effusion or pneumothorax.
Ichthammol or ammonium bituminosulfonate (brand name Ichthyol), also known as black ointment, is a medication derived from sulfur-rich oil shale (bituminous schists). It is used (sometimes in combination with zinc oxide) as a treatment for different skin diseases, including eczema and psoriasis (see below).
Barrier creams may contain substances such as zinc oxide, talc or kaolin to layer over the skin. [5] For hand care they are designed to protect against the harm from detergents and other irritants. [6] The efficacy of barrier creams is controversial. [5] They have not been demonstrated to be useful in preventing hand eczema. [7]
Zinc oxide eugenol (ZOE) was the first agent to be used for preservation. In recent years, glutaraldehyde has been proposed as an alternative to formocresol based on: its superior fixative properties and low toxicity. A nonaldehyde chemical, ferric sulfate, has received some attention recently as a pulpotomy agent.
A 2020 study from the journal Current Dermatology Report summarized the situation as the US FDA currently approving only zinc oxide (ZnO) and titanium dioxide (TiO 2) as safe ultraviolet filters, and for those concerned with coral bleaching, they should use non-nano ZnO or TiO 2 since they have the most consistent safety data.
