There has been known incident of death from cobal chloride ingestion by a 6 year old child who died 6 years after ingesting 30 ml of Cobalt chloride (Jacobziner and Raybin, 1961). Chronic cobalt chloride ingestion causes hypothyroidism (cobalt inhibits the iodination of tyrosine). Cobalt chloride is also known to cause dermatitis.Ĭobalt Chloride has been found to be cause of Transient neutropenia occurred which occurred in a six year old child who ingested 2.5 g (Mucklow et al, 1990). Cobalt chloride is carcinogenic and has been known to cause respiratory irritation. This are called so because of its ability to change colour into pink after reacting with moisture. The problem becomes different with Silica gels coated with cobalt chloride known as indicator gels. At that time, it will need to be reactivated before it can be used again. If eaten in large quantities by children or adults with neuromuscular problems may cause choking as such people are not able to ingest. When the silica gel has absorbed its full capacity of about 40 of its weight in water, the cobalt chloride crystals will turn white because of supersaturation. Even pets show similar reaction as humans like vomiting and nausea on Silica gel consumption. How does the structure change as water molecules are added Anhydrous CoCl 2 has the same structure as cadmium. Silica gel is sometimes supplied containing some cobalt chloride, which indicates the water content blue when it is dry, pale pink when the air round it is damp. If Silica gel is consumed by your pet in large quantity or in small quantity over a period of time, may result in intestinal blockage. When you heat the gel, it loses the water so you can reuse it. It has been found its consumption causes. In 2009, there has been 38,000 reported cases of Silica gel ingestion in USA by American Association of Poison Control Centers out of which 34,000 cases are related to children below 6 years age. As a result consumption of Silica Gel is not considered as emergency. It is considered as a Generally Recognized Safe (GRAS) product by FDA (USA). ![]() When it bonds with two water molecules, (CoCl 2 2H 2 O), it turns purple. One commonly used indicator is cobalt chloride (CoCl 2). the degree of water-saturation of the desiccant. It is sold as dust or solid beads, although termed as gel. The most common desiccant is silica gel, an otherwise inert, nontoxic, water-insoluble white solid. Silica gel is not considered very dangerous as per directive of FDA (USA). ![]()
