Synthetic dyes were frequently utilized in the formulation of marketable lipsticks. However, the practice of synthetic dye has been associated with many health problems. Hence, natural colorant might tender a promising solution to this problem. The Anthocynin which are found in Hibiscus have drawn attention as a potential source of natural colorant to synthetic dye. However, the use of natural colorant in available is limited due to its low stability towards temperature, oxygen, pH, phyoto and colour deterioration across storage. The purpose of this study was to formulate lipsticks with Anthocynin and evaluate its feasibility as natural colorant in lipstick formulation and study its stability across one-month storage period. In this research, Anthocynin was extracted from fresh Hibiscus flowers using water by compression. The extracted anthrocynin pigment was used to prepare lipsticks with basic lipstick formula and the preapared lipsticks were store under light or dark condition for one-month storage period for stability study. The physico-chemical properties of the formulated lipstick like breaking point, surface anomalies, spreadability, skin irritation test, melting point, and perfume stability, homogeneity and colour uniformity were studied and compared with marketable lipsticks. The stability of the formuated lipstick establishes to be stable under dark condition while color loss was greater for lipstick in light condition. Although, lipstick achieved closer standard to commercial lipstick. However, due to the low pigmentation from method, Anthocynin is suggested incorporate in to lip balm application. This research study has proven that Anthocynin could be best replacement for synthetic dye in cosmetics industry for lip balm application.
