A natural preservative is a safe and eco-friendly ingredient used in cosmetics and personal care products to prevent microbial contamination, extend shelf life, and maintain product integrity. Unlike synthetic preservatives, a natural preservative is derived from plant-based or naturally occurring substances, making it ideal for clean beauty formulations.
Mild & Skin-Friendly: Does not cause dryness or irritation like alcohol-based sanitizers.
Long-Lasting Protection: Forms a protective barrier that continuously inhibits microbial growth.
No Strong Odor: Unlike chlorine or formaldehyde-based disinfectants, PHMB is odorless.
Highly Stable: Retains its antimicrobial properties across a wide pH range and temperature conditions.
Yes, PHMB is often included in eco-conscious formulations due to its biodegradability and non-toxic residue. It reduces the need for harsh chemical preservatives while ensuring a high level of microbial protection.
