Formulation and evaluation of medicated polyherbal tattoo ink

Transdermal tattoos offer a potential avenue for administering drugs externally into the dermis, resulting in the creation of a lasting mark. Analyzing complex samples is crucial to assess the presence of ingredients, ensuring the safety of cosmetic products that contribute to health protection. This investigation aims to formulate and assess tattoo ink for treating allergies and inflammation. The study proposes a comprehensive analytical approach, encompassing physical appearance, homogeneity, pH, spreadability, viscosity, and antibacterial evaluation to characterize samples of henna and annatto. Standardizing herbal formulations is imperative to evaluate drug quality based on the concentration of active principles. This paper focuses on the standardization of Henna (Lawsonia inermis Linn) from the Lythraceae family and Annatto from the plant Bixa Orellana. Annatto, known for its lower toxicity and improved biodegradability, can be extracted using water or organic solvents to obtain pigment, tocotrienol, and geranylgeraniol components. These compounds exhibit antibacterial activity, inhibit certain types of cancer, and demonstrate hypocholesterolemic effects, among other properties.
