Methyl p-Hydroxybenzoate (E218) – what is it?
Methyl p-Hydroxybenzoate, also known as methylparaben (E218), is an organic chemical compound from the paraben group. Its chemical formula is C8H8O3. This substance is widely used as a preservative in the pharmaceutical, cosmetic and, above all, food industries. Thanks to its antibacterial and antifungal properties, E218 effectively prolongs the shelf life of products, preventing them from spoiling.
Methylparaben is valued for its low toxicity and good tolerance by the human body, making it one of the safest preservatives available on the market. However, paraben compounds, including E218, are under investigation due to potential endocrine effects, making their safe use constantly monitored.
Properties of methyl p-Hydroxybenzoate
Methyl p-Hydroxybenzoate has a broad spectrum of antibacterial and antifungal activity. It is stable over a wide pH range, which allows it to be used in a variety of food products. In addition, E218 is readily soluble in alcohols and some organic solvents, making it easy to incorporate into product formulations.
Uses of methyl p-Hydroxybenzoate
E218 is mainly used as a preservative in food products, including beverages, sauces, fruit preparations, as well as in cosmetics and pharmaceutical products. Its presence helps prevent the growth of harmful microorganisms, which contributes to the safety and extended shelf life of products.
Where to buy methyl p-Hydroxybenzoate?
Methylparaben (E218) is available in specialty chemical stores, as well as in some pharmacies and online stores offering products for the cosmetic and pharmaceutical industries. Purchasing this preservative, however, requires knowledge of regulations regarding its use in products intended for human consumption.
Methyl p-Hydroxybenzoate and its functions in foods
As a preservative, E218 is crucial in ensuring food safety by inhibiting the growth of bacteria, yeast and mold. As a result, food products can be stored for longer periods of time without the risk of spoilage or reduced nutritional value. Methylparaben is particularly valued in food production, where product safety and shelf life is a priority, while minimizing the impact on product taste and odor.
