Understanding Parabens

What Are Parabens?
Parabens are synthetic preservative compounds widely used in cosmetics, personal care products, pharmaceuticals, and even some food items. Their primary function is to prevent microbial growth, such as bacteria, mold, and yeast, in water-based formulations. This helps to extend the shelf life of products, ensuring they remain safe and effective for longer periods.

Common Types of Parabens:
Some of the most frequently used parabens include:

• Methylparaben

• Propylparaben

• Butylparaben

• Ethylparaben

Parabens are often included in ingredient lists in combinations to enhance their preservative effectiveness. Despite their widespread use since the 1920s, parabens have become increasingly controversial in recent years due to concerns about their potential health and environmental effects.

At Sustai Market, we recognize the importance of addressing these concerns by evaluating products for both safety and sustainability. Our Sustai Score helps identify products that are free from potentially harmful ingredients like parabens, while our Non-Toxic Badge highlights safer alternatives.
