What is Methylparaben + Propylparaben?
Methylparaben and Propylparaben are chemical preservatives commonly used in cosmetics and personal care products. They are esters of p-hydroxybenzoic acid and are derived synthetically for commercial use.
These parabens are effective antimicrobials that help prevent mold, yeast, and bacteria from growing in products. While some studies suggest they may mimic estrogen in the body, the concentrations used in cosmetics are deemed safe by many regulatory bodies.
When reading labels, note that parabens may appear under various chemical names, often indicating their use as preservatives.
Commonly found in: facial creams, lotions, shampoos, conditioners, deodorants
What to watch
- Some studies suggest parabens can mimic estrogen, leading to concerns about hormonal disruption.
- Evidence is mixed regarding the potential carcinogenic effects of parabens at low concentrations.

Parabens are approved for use in cosmetics at concentrations up to 25%, but typical use levels are 0.01% to 0.3%.
