The present invention relates to a personal care composition, particularly, a stable sunscreen composition. The problem associated with a dibenzoylmethane sunscreen is its relatively unstable nature, especially in the presence of a UV-B sun-screen. There is a need for using more readily and easily available compound as a sunscreen stabilizer thereby ensuring reduced cost of such sunscreen compositions. The present inventors have worked intensively on solving this problem and found that a derivative of an active (gingerol) found in ginger i.e. zingerone, provides for such improved stability.
