Product Description
StarSil™ HAS 25 is a non-ionic, organo silicone softener, which when emulsified will develop a smooth hydrophilic finish on cotton, cotton/polyester or polyester fabrics.

StarSil™ HAS 25 is exceptionally stable and is compatible with all products typically used in textile finishing. StarSil™ HAS 25 can also be used to soften terry towel material.
