Some Carrier Oil facts:
 
There are many different kinds of oils and non-oil products that are used in soap, bath salts, scrubs and aromatherapy products.
Here is a list some of the most popular ones.
These are usually easily found, though some are quite costly.

• Pomace Olive - Popular in both gourmet food preparation and soap making. It has no odor and can be heated to a very high temp without risk of smoking or burning. Heavy texture. Light green in color, with an oily feel. Long lasting. Low cost.
• Glycerin - Made from both animal and vegetable sources, this is a popular substance that is not an oil but can be used for so many things it would be hard to imagine trying to make many of the most popular products without it. Thick, smooth texture. Very clear. Somewhat costly in smaller quantities. Lasts indefinitely.
• Grape Seed - Is at the top of many soap and aromatherapy maker’s list of favorites. Long lasting, light textured oil, usually with no oder or color. Low cost. Can't find it? Try a Greek or East Indian Deli or Market.
• Sweet Almond - Is possible the most popular of all the oils due to the medium texture, light almond fragrance. Has a slight golden color and long shelf life. Easy to find. Mid-range cost.
• Jojoba - Another  very popular product, not an oil but often referred to and sold as an oil. Jojoba is a sap and it used as oil. Many aroma therapists say it is without equal. It has a rich golden color and faint pleasant aroma that many people love. Light texture that blends well and leaves on oily residue. It will also keep for many months when stored carefully. Highest cost - fairly easy to find. Often found in health food stores. Comes from a desert plant native to Arizona and California.
  
  Some storage tips: All the products on the list above are best stored in brown glass containers. Keep in a cool, dark place. Avoid heat, sunlight, and freezing. Do not refrigerate. Always clearly label each product with name and date of purchase, plus any other information you consider to be important. For best results try to use in 6 months or sooner. Although some will last much longer, imagine the embarrassment of having a batch go bad immediately after delivery to one of your best clients.
