Parabens are a class of chemicals widely used as preservatives by cosmetic and pharmaceutical industries. Parabens are effective preservatives in many types of formulas. These compounds, and their salts, are used primarily for their bactericidal and fungicidal properties. They can be found in shampoos, commercial moisturizers, shaving gels, personal lubricants, topical/parenteral pharmaceuticals, spray tanning solution, makeup and toothpaste. They are also used as food additives.

This class of chemicals may include butyl paraben; ethyl paraben; heptyl paraben; methyl paraben; propyl paraben
