        abstract = {The formulation and development of lipstick using natural colourants is an emerging trend in cosmetic science, driven by increasing consumer demand for safer, eco-friendly alternatives to synthetic dyes and pigments. This study focuses on the preparation of lipsticks incorporating plant-based colourants, such as beetroot, papaya, annatto, hibiscus, grapes, butterfly pea and dragon fruit, as well as other natural ingredients like beeswax, shea butter, and essential oils, to create a high-quality, sustainable product. The objectives were to evaluate the stability, texture, and colour performance of the natural colourants in the lipstick matrix, ensuring the product meets aesthetic, sensory, and safety standards. Lipstick formulations were developed through careful selection and optimization of ingredients to achieve desirable properties, such as smooth application, long-lasting wear, and vibrant pigmentation. The study further investigates the impact of natural colourants on the physicochemical properties of the lipstick, including melting point, spreadability, and moisture retention. Results indicate that natural colourants can successfully be incorporated into lipstick formulations without compromising product performance, providing an environmentally friendly and skin-safe alternative to synthetic cosmetic products. This research contributes to the growing interest in natural cosmetics by presenting an effective method for the development of lipsticks with natural colourants, paving the way for healthier, eco-conscious beauty solutions.},
