E217 - Natriumpropyl-p-hydroxybenzoat

Origin

Sodium propyl para-hydroxybenzoate, also known as propylparaben sodium, is a synthetic preservative. It is the sodium salt of propyl para-hydroxybenzoic acid (propylparaben). Propylparaben itself is derived from para-hydroxybenzoic acid, which can be found naturally in some fruits and vegetables, though the propylparaben used commercially is synthesized.

Usage

E217 is used as a preservative in a variety of products, including foods, pharmaceuticals, and cosmetics. It is effective against a wide range of microorganisms, including bacteria, yeasts, and molds. In food, it helps to prevent spoilage and extend shelf life. It is often used in combination with other preservatives to enhance its effectiveness. Specific applications include baked goods, jams, jellies, processed fruits and vegetables, and sauces. It is also used in some topical medications and cosmetic products to prevent microbial growth.

Side Effects

Parabens, including propylparaben, have been the subject of some controversy regarding potential endocrine-disrupting effects. Some studies have suggested that they can mimic estrogen and may be linked to adverse health effects, particularly with high levels of exposure. However, regulatory bodies like the EFSA and FDA have evaluated the available scientific evidence and have established acceptable daily intake (ADI) levels. The ADI for parabens (including methyl-, ethyl-, propyl-, and butylparabens) is 0-10 mg/kg body weight per day (expressed as the sum of methyl- and ethylparabens and 0.2 times the sum of propyl- and butylparabens). At levels typically used in food and cosmetic products, the risk of adverse effects is considered low. Some individuals may experience allergic reactions to parabens, although this is relatively uncommon.

Regulatory Status

Sodium propyl para-hydroxybenzoate (E217) is permitted for use as a food additive in many countries, including those in the European Union. However, its use is regulated, and maximum permitted levels are specified for different food categories. The European Food Safety Authority (EFSA) has evaluated the safety of parabens and established an ADI. The FDA also regulates the use of parabens in food and cosmetics in the United States.
