AMMONIUM FLUOROSILICATE

Description

Ammonium fluorosilicate, also known as ammonium hexafluorosilicate, is a crystalline compound with the chemical formula (NH4)2SiF6. This inorganic salt is widely used in various industrial and dental applications due to its unique properties. In skincare and cosmetics, it functions primarily as a buffering agent and pH adjuster.

The compound is synthesized by reacting hydrofluoric acid with ammonium hydroxide and silicon dioxide. It appears as white, odorless crystals or powder, highly soluble in water. Ammonium fluorosilicate's ability to release fluoride ions in aqueous solutions makes it valuable in dental products for enamel remineralization.

In skincare formulations, it helps maintain product stability by regulating pH levels. Its buffering capacity ensures that the pH of a product remains consistent, even when exposed to external factors. This stability is crucial for preserving the efficacy of active ingredients and preventing skin irritation.

While generally considered safe in regulated concentrations, ammonium fluorosilicate can be toxic if ingested in large amounts. Its use in cosmetics is strictly controlled, with maximum allowed concentrations typically set by regulatory bodies. Formulators must exercise caution and adhere to guidelines when incorporating this ingredient into skincare products.
