E586 - 4-hexylresorcinol

Origin

4-Hexylresorcinol is a synthetic organic compound. It's not naturally derived from plants or animals but is manufactured through chemical synthesis. It belongs to the class of alkylresorcinols, which are known for their antioxidant and antimicrobial properties. Its synthesis involves the alkylation of resorcinol with hexyl groups.

Usage

4-Hexylresorcinol is primarily used as an antioxidant to prevent enzymatic browning in foods, particularly in seafood and fruits. It inhibits polyphenol oxidase (PPO), the enzyme responsible for browning reactions when these foods are exposed to air. It is also used as an antimicrobial agent, extending the shelf life of food products by inhibiting the growth of bacteria, yeasts, and molds. In the cosmetic industry, it is used as a skin-lightening agent and antioxidant in topical formulations. The typical concentration used in food applications ranges from 0.01% to 0.1%, depending on the specific product and application.

Side Effects

4-Hexylresorcinol is generally considered safe for use in food and cosmetic applications within the permitted concentrations. Studies have shown low toxicity when ingested or applied topically. Some individuals may experience mild skin irritation or allergic reactions, particularly with higher concentrations in cosmetic products. No significant long-term health effects have been reported with its use as a food additive at approved levels. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated 4-hexylresorcinol and established an Acceptable Daily Intake (ADI) of 0-0.2 mg/kg body weight.

Regulatory Status

4-Hexylresorcinol is approved for use as a food additive in several countries, including the United States, Canada, and the European Union. In the EU, it is designated as E586. Regulatory bodies such as the FDA (in the US) and EFSA (in Europe) have established guidelines for its use, specifying maximum permitted levels in various food products. These regulations ensure that the additive is used safely and effectively to prevent food spoilage and maintain product quality.
