Velsan® Flex (INCI: Capryloyl/Caproyl Anhydro Methyl Glucamide, Water) is a naturally derived, multifunctional preservation booster and solubilizer. Based on innovative sugar-surfactant technology, this liquid active is derived from sustainable palm kernel oil and corn-sourced glucose. It is specifically engineered to overcome the preservation challenges of high-water-content formulations, allowing for a dramatic reduction in traditional preservative loads while enhancing the solubility of lipophilic ingredients.
Key Benefits and Performance
- The “Preservative-Halving” Effect: It acts as a powerful synergistic booster that can reduce the required concentration of conventional preservatives by up to 50%. By destabilizing microbial cell membranes, it makes the primary preservative significantly more lethal.
- Mould Gap Closure: A critical strength of Velsan® Flex is its ability to bridge specific antimicrobial gaps. When used in a 1:1 ratio with Benzoic Acid, it successfully closes the gap against Aspergillus brasiliensis (mould), providing a robust, broad-spectrum defense.
- Solubilizing Powerhouse: Unlike many preservation boosters that are difficult to incorporate, Velsan® Flex is an excellent oil solubilizer. It helps incorporate fragrances, essential oils, and other lipophilic actives into clear, water-based systems without the need for high levels of PEG-based surfactants.
- Odour Masking: In formulations utilizing Phenoxyethanol, a 1:1 blend with Velsan® Flex helps mask the sharp, chemical odour typically associated with that preservative, leading to a more premium consumer experience.
- Transparent Formulation Specialist: Because it is fully water-soluble and aids in clarity, it is the “gold standard” for difficult-to-preserve transparent products like micellar waters and toners.
Formulation Guidelines
- Application Suitability: Ideal for high-water-content products including micellar gels, facial toners, sheet masks, O/W emulsions, body washes, and wet wipes.
