Need for Biodegradable chelating agent
Background-Metal ion challenges across various industry:
Metal ions influence chemical processes as well as performance of many products. A wide range of problems associated with metal ions can be solved using chelating agents. Historically EDTA, NTA were the work horses of many industrial processes such as homecare, detergent, industrial cleaners, etc. However, EDTA and NTA are non- biodegradable chelating agents and are potential carcinogens. As a result, the need to develop new green chemistry arose. The new biodegradable chelant, GLDA is derived from renewable sources with better ecological and toxicological profiles.
Key unique differentiations offered by GLDA:
- Environmentally Friendly Technology – GLDA is classified as readily biodegradable (> 60% degraded within 28 days) according to the internationally recognized OECD 301D test.
- Wide range of operating window – GLDA operates across wide range of pH making it conducive to use in strongly alkaline hard surface cleaning application that includes food processing, kitchen cleaning and automatic dishwashing products.
- Formulation flexibility, compatibility and Synergy– There is an increased interest in the use of GLDA in disinfectant formulations. Like EDTA, 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 – 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.
- GLDA solutions for broad portfolio of industrial applications – GLDA is instrumental in reducing the detrimental effect of metal ions in various industrial processes such as paper manufacturing, personal care formulations, food industry, pharmaceutical formulations, metal working area etc.
