Propylene glycol is a colorless and odorless liquid which may be derived from either petroleum, natural gas, or vegetable sources. The propylene glycol in Bosmeric-SR is plant based from vegetable sources. As with all our ingredients, we source plant-based ingredients when available as an option. Propylene glycol has a long history of safe use in personal care products. It is on the FDAs list of ingredients that are Generally Recognized As Safe (GRAS). Propylene glycol in Bosmeric-SR is an excipient or inert ingredient and thus is used on the machinery that the tablets slide down onto the bottle. It is not a major or minor ingredient but an inert/excipient ingredient that is so small it can’t be measured. However, unlike most manufacturers we disclose everything the product comes in contact with since we provide our products to hospitals, university and clinical trials.
