Transcription

1 ylasome EG10 Excellent Moisturizing Through the Delivery of Water ylasome is a registered trademark of Genzyme Corpora on. US Patents 5,143,724; 5,246,698; 5,399,351; other patent pending

2 ylasome is the tradename of ylan B gel (cross- linked hyaluronic acid) used in topical applica ons. ylamed Research, Inc. has the exclusive, global license for ylasome technology for use in the topical cosme c and skin care field. Lipo Chemicals is the exclusive worldwide distributor for ylamed Research.

4 INCI name: Sodium yaluronate Crosspolymer CAS No.: EINECS No.: Polymer, Exempt Consists of an aqueous gel of crosslinked hyaluronic acid. Polymer content: 6% by weight of polymer plus bound water

5 Chemical Structure C - N C 3 N C - C 3 S S C 3 C - C - N N C 3 Sulfonyl- bis- ethyl crosslinks and hydroxyethyl sulfonyl ethyl pendant groups

6 Crosslinking

7 Delivery of Water Unique non- equilibrium gel. Developed specifically in a non- equilibrium state with gel domains that are not completely swollen. Gel domains, which contain ghtly bound water, are surrounded by free water. The gel forms a smooth film on the skin and con nuously delivers the bound water.

9 Skin Moisturiza on Study: Confocal Raman Spectroscopy Ex vivo surgically removed skin (including stratum corneum, viable epidermis, and some dermis). ylasome EG10 vs. yaluronic Acid, both at 0.1% polymer weight in D 2 Performed at Rutgers University

10 Experimental Procedure 5 µl D 2 - based test material applied to 2x2 cm 2 surgically removed skin. eld at 55% rela ve humidity (D 2 ) and room temperature for 24 hours. Placed in milled brass sample holder and covered with glass cover slip. D 2 content in the skin measured by confocal Raman spectroscopy in the x and z axes.

Skin protein component phenylalanine (Phe), band area is used as an internal standard to correct for sca ering losses with depth. The ra o of the D 2 peak to the Phe peak indicates the moisture content at the measurement site Wavenumber (cm- 1)

16 Conclusion A er 24 hrs at 55% Rela ve umidity: ylasome EG10 treated skin contained 6x more moisture in the total sample and 5x more moisture in the stratum corneum than hyaluronic acid treated skin.
