Propylene glycol is one of the most widely used cosmetic ingredients, it is a humectant. It is a clear, colorelss, viscous liquid, slightly bitter-tasting. It is the most common moisture-carrying vehicle, other than water itself, in cosmetics. Absorbs moisture, acts as a solvent and a wetting ingredient. Use as a carrier to dissolve dry colorants and create liquid ones.
The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the EPA have not classified propylene glycol for carcinogenicity.
Uses: (1) Moisturizer in medicines, cosmetics and food products. (2) Medical/sexual lubricant. (3) Solvent for food colors and flavorings. (4) Carrier in fragrance oils and melt and soap bases. (5) Antibacterial lotions and saline solutions. (6) Food, cake mixes, salad dressings, soft drinks, popcorn, food colorings, fat-free ice cream and sour cream. (7) Preservative in toiletries and cosmetics. (8) As an ingredient in vaping liquids.
For those of you who may believe that propylene glycol means "antifreeze": antifreeze is made from ethylene glycol.
The United States Pharmacopoeia (USP) is a non-profit organization that determines safe standards for drugs as well as medical devices and diagnostics. It s our understanding that once a USP-certified container is opened and its contents repacked into various sizes, the product loses its USP certification. We purchase in large quantities and repack; thus, the certification we receive on any USP-certified product which we repack is lost the moment we take this step. This product is Kosher but we do not provide paperwork for this certification.
We have taken the liberty of copying this from Tom’s of Maine literature:
Propylene glycol is considered a safe and appropriate ingredient not just for cosmetic products, but also for ingested products like food and pharmaceuticals. It is on the US Food and Drug Administration's list of ingredients which are Generally Recognized As Safe (GRAS) and is recognized by the World Health Organization as safe for use.
There have been claims made that propylene glycol is an inappropriate ingredient for cosmetics and foods because it can also be used in products (such as antifreeze) which one would not want to consume. Such observations are well-intended but ultimately not very informative. It is ethylene glycol, for example, which is a more common ingredient in anti-freeze and which is, in fact, highly toxic. Simply because propylene glycol has many different applications does not make all the products which contain it the same. INCI: Propylene glycol.
OUT OF STOCK ISSUES: If a customer orders a large quantity of a product and all of the product is not in stock when the order is entered into our system, once the new stock arrives we will ship separately whatever quantity we may owe the customer. Most of our restocking orders arrive at our warehouse 5-7 business days after we place a restocking order, sometimes sooner. Should the distiller or vendor inform us restocking will take longer than 7 business days, we’ll promptly notify the customer.
Please note that we do not allow order cancellations for any reason and we don’t allow removal/cancellations of products which become partially or completely out of stock after the customer places an order.
Raw materials/ingredients are dispensed by weight. Many customers ask how many ounces in a pound, there are 16 ounces in one pound. These are not fluid ounces, they are ounces by weight.
EO = essential oil
FO = fragrance oil
Our containers are filled with products to where our commercial digital scales indicate the container should be filled. Some containers will be filled to the top, some will not.
HOW OILS ARE DISPENSED: All our products are dispensed by weight. EO's in 8 oz. through 2 lbs. - amber plastic pharmaceutical-grade bottle. EO's in 5 and 10 lbs. - heavy duty plastic container w/pouring spout, the oil may remain inside the container at least 2 months. EO's in sizes of 25+ lbs. - industry-standard metal or plastic can with a pouring spout, the oil may remain inside the metal can indefinitely and up to 2 months in the plastic pail. It's our decision in which type of pail we dispense the product, metal cans are not readily available. CARRIER OILS - plastic bottles/pails depending on the size ordered, do not need to be transferred to glass unless you wish to do so. FO's - in plastic containers, contents do not need to be transferred to glass unless you wish to do so.
Essential oils in sizes from ½ oz. to 4 oz. are dispensed in amber glass bottles without orifice reducers or glass droppers. If we ever run out of amber glass bottles, we reserve the right to use any other glass bottle available at that time. The only sizes of EO's dispensed with orifice reducers are 1/32, 1/16, 1/8 and 1/4 oz. sizes. If you require bottles/vials with orifice reducers or Eurodroppers, we sell those separately.
HOW TO STORE: Upon receipt, EO's dispensed in plastic bottles MUST be transferred into amber glass bottles. EO's, FO's and BUTTERS should be stored in tightly-sealed containers away from direct light and heat. Many oils could be highly flammable, keep away from open flames. Refrigerating butters could adversely affect the consistency of the butter, please join our Forum if you need to learn how to handle and store products.
