MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202641123165 A) filed by Arun Kumar Ramamoorthy; and Evy Alice Abigail Manickam on October 14, 2026, for Plant-Based Colorimetric Detection Kit And Indicator Strip For Screening Dermatological Heavy Metal Toxicity.
Inventors include Arun Kumar Ramamoorthy; Evy Alice Abigail Manickam; Dhakshayani Gnana Prakasam; Deepadharshini Vetrivel; Priyadharshini Gunasekaran; and Vaibhav Arumugam.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention discloses a plant-based colorimetric detection kit and a disposable colorimetric indicator strip for point-of-use screening and early clinical prevention of dermatological heavy metal toxicity caused by cosmetic contaminants, particularly nickel ions (Ni2+). The kit comprises a solid cellulose substrate strip bearing an immobilized, ternatin-rich Clitoria ternatea flower extract, a specialized sample-dissolving reagent for solubilizing lipidic and emulsified cosmetic matrices, and a visual reference chart. Upon contact with solubilized topical samples, reactive anthocyanins within the indicator layer undergo rapid coordination complexation with nickel ions, inducing a distinct, concentration-dependent visual color change within 60 seconds without requiring analytical instrumentation. Manufactured via a controlled stepwise drop-casting and low-temperature thermal-drying process (37°C–50°C), the eco-friendly, biodegradable test strip enables rapid, on-site dermatological risk assessment to prevent contact dermatitis, cutaneous barrier disruption, and systemic toxicant absorption in susceptible patient populations.
