Environmentally Friendly Technology – Glutamic acid diacetate (GLDA) is classified as readily biodegradable (>60% degraded within 28 days) according to the internationally recognized OECD 301D test.
Wide range of operating window – Glutamic acid diacetate (GLDA) operates across wide range of pH making it conducive to use in strongly alkaline hard surface cleaning applications that includes food processing, kitchen cleaning and automatic dishwashing products.

Formulation flexibility, compatibility and Synergy– There is an increased interest in the use of Glutamic acid diacetate (GLDA) in disinfectant formulations. Like tetrasodium ethylenediaminetetraacetic acid (EDTA), Glutamic acid diacetate (GLDA) can be used together with biocides to improve the biocidal performance of a disinfection system.

Offers unique opportunity for skin friendly personal care product development – Glutamic acid diacetate (GLDA) is also used in personal care products. GLDA is free from genetically modified raw materials and is not irritating to skin or eyes, these properties are suitable in the development of new personal care products.

Glutamic acid diacetate (GLDA) solutions for broad portfolio of industrial applications – Glutamic acid diacetate (GLDA) is instrumental in reducing the detrimental effect of metal ions in various industrial processes such as paper manufacturing, personal care formulations, food processing industry, pharmaceutical formulations, metal working area etc.

Tetrasodium Glutamate Diacetate inactivates metallic ions (charged particles) in product formulations, hence acting as is a chelating agent. Free roaming iron and copper ions in formulations can lead to rapid oxidation. Using a chelating agent helps to slow this process, allowing for the creation of products with improved stability and appearance. This also improves the effectiveness of preservative ingredients, allowing us to use a lower percentage of these, for safer shelf-stable products. Tetrasodium Glutamate Diacetate is often found in sunscreen, facial cleanser, shampoo, makeup, lotion, cleansing wipes, bar soap, and other cleaning products.


Tetrasodium Glutamate Diacetate is an organic salt synthesized from glutamic acid (an amino acid abundant in nature).
