Online Published on 12 January, 2024. Abstract A novel, fingerprint dusting composition, based on a commonly used food dye, tartrazine has been propounded. The proportion of the dye in the composition is 10%, the remaining being an adhesive mixture of pulverized chalk and talcum powder. The formulation gives sharp and clear fingerprints on a wide range of surfaces, absorbent and non-absorbent; white and multicolored. The wide range of applications and the low cost of preparation make it suitable for a developing country like India. Top Keywords Adhesive, Dye, Fingerprints, Powder, Tartrazine. Top |
