POLYAMINOPROPYL BIGUANIDE

Description

Polyaminopropyl biguanide (PHMB) is a synthetic antimicrobial agent widely used in skincare and personal care products. This water-soluble compound is known for its broad-spectrum efficacy against bacteria, fungi, and certain viruses. PHMB's molecular structure allows it to bind to microbial cell membranes, disrupting their integrity and leading to cell death.

In skincare formulations, PHMB typically serves as a preservative, extending product shelf life by inhibiting microbial growth. Its effectiveness at low concentrations (usually 0.01-0.3%) makes it an attractive option for formulators. PHMB demonstrates good compatibility with other cosmetic ingredients and maintains stability across a wide pH range.

Studies have shown PHMB to have a favorable safety profile when used at recommended levels. It exhibits low skin irritation potential and minimal risk of sensitization. The ingredient's non-volatile nature contributes to its long-lasting antimicrobial action on the skin surface.

PHMB finds applications in various skincare products, including cleansers, toners, moisturizers, and acne treatments. Its ability to combat acne-causing bacteria makes it particularly useful in formulations targeting blemish-prone skin. Additionally, PHMB's film-forming properties can provide a protective barrier on the skin, potentially enhancing its moisturizing effects.
