Formulation and Evaluation of Lipstick Made By Natural Colourant Bixa Orellana

The study presents the formulation and evaluation of lipstick through natural colour agents Bixa Orellana(annatto) and Beta vulgaris (beetroot). The primary objective was to create a lipstick that combines aesthetic appeal with functional benefits, using natural ingredients to ensure safety and environmental sustainability. In General the lipsticks use the colour extracted from Cochinea insects and it can be considered as animal harm and not skin friendly. The formulation process involved the careful selection of waxes, oils, and pigments to achieve the desired texture, color, and stability. The resultant lipstick was subjected to a series of rigorous evaluations to ensure quality and performance. Primarily, the pH test was conducted to ensure the lipstick's compatibility with the natural pH of the skin, resulting in an optimal pH level that avoids skin irritation. The melting point test confirmed the product's stability across various temperature ranges, ensuring that it remains solid in typical environmental conditions. Solubility test with water, ethanol and methanol which helps to ensure the resistance to water based removal, and uniform dispersion of pigment and compatibility in alcohol. Perfume stability test is conducted to ensure that the fragrance remain consistent safe and pleasant. skin irritation test was conducted with human volunteers, demonstrating that the lipstick does not cause adverse skin reactions. Surface anomalies test to detect any visual or textural imperfection on lipstick surface that could affect the product quality and user experience. The colour imparting test in lipsticks evaluates how effectively the product transfers its color onto a surface essentially measuring its colour payoff and application quality. All tests yielded results within the acceptable reference ranges, validating the formulation's success. This study contributes to the development of safe, natural colouring agent which ensure safety by incorporating natural colouring agent.
