Why Are Parabens Used?

The salts of the parabens have bactericidal and fungicidal properties. They are used extensively because when they are added to a product, they prevent its decomposition. An additional factor is their resistance to the high temperatures used in food processing. Apart from being efficacious preservatives, they are cost-effective too. Naturally occurring preservatives are inefficacious compared to parabens.

While numerous preservatives are commercially available, the ideal preservative is inexpensive, has a long shelf life with broad antimicrobial coverage, is compatible with other chemicals, and is not irritating or toxic. Parabens meet many of these expectations and, therefore, have become one of the most commonly used preservatives in cosmetic preparations and topical therapeutics.

It is important to do a sensitivity test before you start using any cosmetic product. The test is simple. Apply the new cosmetic to a small skin patch and then observe any changes in the skin. The observation time may range between 24 and 48 hours. If no change in the skin patch is observed, you can start using the cosmetic.
