POWERSOFT® UP 68 is a nonionic micro emulsion concentrate of a reactive modified aminofunctional polydimethylsiloxane for use in non-yellowing and medium hydrophilic textile finishing.


POWERSOFT® UP 68 is particularly suitable in softener formulations for the impregnation of fibers and textiles. POWERSOFT® UP 68 imparts a soft, drapable and elastic touch to woven and knitted fabrics.

In comparison to usual silicone-based, medium hydrophilic softeners POWERSOFT® UP 68 shows excellent stability in the presence of salt and resins even under high shearing conditions.

POWERSOFT® UP 68 is readily dilutable with cold water to any desired concentration. Dilutions of the product are extremely resistant to high alkaline conditions up to pH 11.

Furthermore POWERSOFT® UP 68 can be used in direct combination with many optical brighteners due to its high compatibility with such compounds. However, the compatibility should be tested on a case-by-case basis.

In contrast to many conventional silicone softeners, POWERSOFT® UP 68 does not turn cotton and other hydrophilic substrates completely hydrophobic. Cotton treated with POWERSOFT® UP 68 shows medium hydrophilicity which offers advantages if overdyeing of the fabric is required.

When applied under normal conditions as part of a softener formulation, POWERSOFT® UP 68 has no effect on the whiteness degree.
