Until recently, manufacturers who wanted to make anti-aging and wrinkle reduction claims about their cosmetic and personal care items were required to either use DuPont™ Glypure® L, which includes a 
pass-through license from TriStrata, a wholly owned subsidiary of NeoStrata Company, Inc., or to set up their own glycolic acid licensing agreement directly with TriStrata.
This all changed when the patents related to NeoStrata and TriStrata alpha hydroxyl acid anti-aging and wrinkle reduction technology expired in February 2009 for all countries except Canada and Australia and Europe for nail care.
So now, for most of the global market, you no longer need to worry about managing a licensed product. You have the freedom to introduce new anti-aging products to meet increasing consumer demand without the added concern or expense of a licensing agreement. And, if you want to sell anti-aging products into Canada and Australia and nail care products in Europe, you can still choose DuPont™ Glypure® L, which offers all the benefits of our ultra pure form of glycolic acid plus the convenience of a pass-through license.
