In an ongoing endeavor to honor our Earth and your health we have elected to offer glass as an option to BPA-free plastic bottles in our full-sized hair, body and baby care products. Our research has shown that BPA-free PET (#1), the plastic bottle we use for Hair Care, Body Care and Baby Care, is one of the safest options over some of the other available plastics. However, all plastics demonstrate varying levels of leaching chemicals, particularly when heated. But now, we have taken the next step and shall be offering Ultraviolet Blue Glass Bottles, which protect against UV rays that can alter the ingredients. Easier to recycle, safer for your body.
