"Soarnol®" is commonly used in barrier tube applications such as toothpaste, cosmetics, glues and caulks. In these applications "Soarnol®" serves as a barrier not only to oxygen but also for various hydrocarbons (e.g. flavors and fragrances). "Soarnol®"'s ability to prevent oxidation of the oils that are components of cosmetics, and to preserve other aromatic components, is expanding the use of "Soarnol®" as a barrier material in this application. In addition, "Soarnol®" exhibits almost no decomposition gases during extrusion, which ensures that cosmetic properties are not compromised by the presence of undesirable odors coming from decomposition of the resin itself
Decomposition gases
| Soarnol® | |
|---|---|
| Weight loss | Less than 1% |
Under nitrogen condition (250 deg C/60min)
Yellowing
Condition: 150 deg C, 5hrs
Yellowing refers to a kind of structural change, such as an increase in double bond due to thermal decomposition. "Soarnol®" has properties that prevent thermal decomposition and yellowing.
