Activonol-5N (Pentylene glycol) is a colorless, odorless, water-soluble liquid that serves as a high-performance moisturizer, solvent, and antimicrobial booster. It is specifically designed for the “multi-hurdle” preservation approach, providing a bio-based alternative to synthetic glycols without compromising on clinical efficacy or sensorial quality.
Key Features & Technical Benefits
-
Potent Antimicrobial Efficacy: Verified by MIC data against Gram-positive/negative bacteria, yeast, and mould. It offers a good antimicrobial effect on its own and an “excellent” synergistic effect when paired with other glycols or preservatives.
-
Moisturization & Skin Feel: Described as an excellent skin moisturiser that provides a smooth, non-tacky finish.
-
Sunscreen Enhancer: Unique ability to enhance the water resistance of sunscreen formulations, a critical benefit for SPF products.
-
Superior Safety: Human skin patch tests (48 hours) at a 5% concentration in an O/W emulsion reported zero irritation.
Formulation & Use Guidelines
-
Format: Liquid; easy to incorporate into the water phase or post-emulsification.
-
Preservation Strategy: Most commonly used as part of a multi-hurdle preservation approach rather than a standalone system.
-
Applications: Suitable for high-end skincare, sun care, and natural alternative preservation systems.
