  • Patent number: 7794741
    Abstract: A personal care composition is provided having a fragrance which incorporates limonene, gamma terpinene, ethylene brassylate or combinations thereof in conjunction with a quaternary ammonium salt. The salt has a structure AB, wherein A is a cationic charge component, B is an anionic charge component, and A has one quaternized nitrogen atom, at least two hydroxyl groups and a molecular weight no higher than about 250. The quaternary ammonium salt functions as a scent boosting agent to enhance volatilization of the fragrance components when the personal care composition is first applied to skin or hair of the human body.
