Dissolvine® GL-47-S is a high-performance, biobased chelating agent derived from monosodium L-glutamate (MSG), a naturally occurring amino acid. The product is a clear, aqueous solution of GLDA-Na₄, offering superior metal ion binding capabilities across a wide pH range.
With over half of its carbon content sourced from renewable biomass, Dissolvine® GL-47-S stands out as a safer, sustainable alternative to conventional chelators such as EDTA, NTA, and phosphates.
Notably recognized by the U.S. EPA’s Safer Choice program, Dissolvine® GL-47-S provides excellent biodegradability, low toxicity, and an outstanding environmental profile. It enhances cleaning efficacy through strong chelation of hard water ions (e.g., Ca²⁺), making it a valuable ingredient in personal care, home care, and industrial cleaning formulations. The product contains less than 0.1% NTA and does not require hazardous labeling.
Applications
Dissolvine® GL-47-S is widely used across multiple sectors due to its strong chelating performance and safety profile:
- Cleaning and Detergents: home care, industrial and institutional cleaners, water softeners
- Personal Care and Cosmetics: skin cleansers, shampoos, and other rinse-off products
- Agriculture: micronutrient delivery systems
- Industrial Formulations: metal ion control in water treatment, coatings, and manufacturing
- Biocidal Formulations: booster for antimicrobial performance
Key Benefits
- Biobased Origin: derived from food-grade MSG; >50% carbon content from renewable sources
- Readily Biodegradable: recognized as food by bacteria due to its natural amino acid structure
- Superior Chelation: effectively binds di- and trivalent metal ions, including Ca²⁺ and Fe³⁺
- Safer Profile: low toxicity, low ecotoxicity, and non-sensitizing to human skin
- Non-Eutrophying: unlike phosphates, does not contribute to aquatic nutrient loading
- U.S. EPA Safer Choice Listed and accepted by multiple international safety standards
- Wide pH Range Use: fully soluble and effective across acidic, neutral, and basic conditions
- Stable Liquid Form: easy to incorporate into various aqueous systems
