Improving quality of fabric softeners by application of silicone derivative

  • Print

Key words:
fabric softeners, silicone derivatives, quality.

Fabric softeners are classified as household products. They are added at the final stage of
the washing process, i.e. rinsing. They are designed to give the cleaned and rinsed fabric additional features: appropriate scent, feeling of softness, lack of electrization effect, easier
ironing. The main component of the fabric softeners are cationic surfactants. Moreover,
specific compounds may also be introduced to the softeners formula in order to increase the
impression of "softness", e.g. various types of silicones.
In this work we present results of studies on the effect of addition of the silicone derivative
(PD – Polidimethylosiloxane diquat) to the fabric softener at 0.1 and 1% concentration on the
softening properties and the rewettability of the fabric. The cationic surfactant used in the
studies was Dialkyloylethyl Hydroxyethylmethylmonium Methylosulphate (DHM). Solutions
were used at concentrations of respective fluids at 0.002; 0.02; 0.2; 2 and 20%.
It was found that the partial replacement of a primary surfactant DHM with PD derivative
of silicone at 0.1% and 1% did not significantly affect fabric softening effect. On the other
hand, adding of the silicone derivative PD into formulations at concentration of 0.1% resulted
in improving the rewettability of the fabric.
