Silgan Plastics (Chesterfield MO) molds the oblong-shaped bottles using Eastman Chemical's (Kingsport TN) polyethylene terephthalate glycol® resin. Mary Kay purchases the bottles through distributor Berlin Packaging (Chicago IL). Opaque white is used for Mary Kay® Body Care Moisturizing Lotion and Cleansing Gels while clear bottles hold two Private Spa limited-edition promotional offerings. Mary Kay assistant manager Carol Doyle explains "The clear bottles show off our color-coded formulas and showcase the coordinating colored graphics on our labels. The opaque bottles provide a good background to complement our blue and gray label graphics. It's a way of achieving two distinctive looks from the same bottle." Doyle says the PETG material allows consumers to squeeze the bottle easily to facilitate product dispensing.
