At Pompeii Organics we like to keep things fresh. Oils in this section are past their peak therapeutic life. When an oil is past it's recommended shelf life, it may become oxidized or a skin irritant. Oils more susceptible to oxidization are those high in monoterpenes such as citruses and conifers.
We recommend these oils for use in cleaning (counter sprays, laundry, deodorizing, etc.) We do not recommend older oils for skin application.
