SYNTRAN PC 5227:   Polyacrylate-15 (and) Polyacrylate-17

The Syntran PC 5227 is an acrylate grafted olefin polymer designed specifically to increase the efficacy of UV absorbers.  The use of Syntran 5227 should permit formulators of sun protection products to reduce the high cost of active SPF ingredients.

This innovative, multi-functional polymer was developed by grafting an amorphous functional acrylic polymer section onto a crystalline polyethylene backbone.  The crystalline portion provides water resistance, elasticity and tactile attributes such as lubricity and “feel”.  The amorphous portion provides film formation, adhesion, substantivity, and formulation flexibility.

In a typical film the crystalline wax tends to migrate to the surface on drying.  The amorphous graft polymer portion slows the migration so that the wax is more evenly distributed through the film which results in more uniform distribution of actives throughout the film.  Syntran PC 5227 enhances this known effect by providing a combination of cationic and anionic functionality to the polyethylene .

Formulations based on SYNTRAN PC 5227 show the following properties:

Boost the effectiveness of SPF ingredients
Reduce levels of costly active ingredients
Improves drag and feel
Reduces potential irritancy caused by UV absorbers
Provides water resistance properties and film elasticity

Typical Physical Properties

• APPEARANCE:    White emulsion

Storage

SYNTRAN PC 5227 is not freeze-thaw stable and should therefore be kept at temperature of 5° C to 35° C.

SYNTRAN PC 5227 is storable in original sealed containers and properly monitored storage tanks at ambient temperature at least one year storable.
