Product Introduction

Parabens, including Methylparaben (MP) and Propylparaben (PP), are synthetic preservatives that mimic naturally occurring compounds found in some fruits and vegetables. They are widely used to prevent microbial contamination and extend product shelf life.

They exhibit synergistic effects when used in combination — Methylparaben is more effective against bacteria, while Propylparaben is stronger against yeasts and molds. Together, they offer complete microbial protection.

Parabens are non-volatile, odorless, and stable over a wide pH range (4–8), making them ideal for both leave-on and rinse-off products.

Key Features and Benefits:

Broad-spectrum antimicrobial activity: Effective against bacteria, molds, and yeasts

Synergistic effect: Enhanced efficacy when used as a blend (e.g. MP + PP)

High stability: Resistant to heat, light, and pH variations

No odor or color: Does not affect product aesthetics

Low toxicity and well-studied: Global regulatory bodies have evaluated and approved safe use limits

Applications:

Cosmetics & Personal Care: Creams, lotions, shampoos, conditioners, deodorants, makeup

Pharmaceuticals: Oral syrups, ointments, gels, eye drops

Food Industry (in some regions): Jams, sauces, beverages (within specified limits)

Note: Usage in foods is restricted in several countries, and should be checked against local regulations (e.g. EU regulation EC No 1333/2008).
