Chemical nature Fatty acid condensation product, wax
Physical form Pale yellowish, aqueous dispersion
Shelf life Basosoft ® SMS can be kept in the original sealed containers at temperatu-
res between 5 and 30 °C for at least 12 months. Partly used containers
should be kept tightly closed and used up as soon as possible.
Properties
Solubility Miscible with cold water in all proportions
Ionicity Non-ionic emulsified
Compatibility Basosoft® SMS is compatible with most finishing agents. If several pro-
ducts are to be mixed together, their compatibility should first be tested.
Product specifications Tolerances for test characteristics are given in the product specification.
Application
Fields of application Softener for all types of fibres, alone and in blends
and finishing effects
• Soft and smooth handle
• Antistatic properties
• Improves tear strength and abrasion resistance.
• Improves sewability
• When applied in resin finishing, Basosoft® SMS reduces the tendency to
creasing.
• The finishing effects are largely washfast.
Application conditions and rates Basosoft® SMS can be applied both by padding and by the exhaust
process.
Exhaust process
Basosoft® SMS can be applied in circulating-liquor machines, winch becks,
and jet machines.

Notes In the padding process the ready-to-use finishing liquor should have a pH
of approx. 5.0.
1 g/l prediluted Kieralon® JET-B Conc. should be added to all recipes.
Basosoft® SMS is low-foaming, stable to shear, and free from paraffin wax
and silicones.
Alkaline goods should be adjusted to a slightly acid pH before finishing.
The wash and rub fastness of coloured and printed goods are generally
unchanged. Only in rare instances do these properties deteriorate.
An adverse effect on the degree of whiteness is very unlikely under normal
curing conditions.
If it is used together with cationic aftertreatment agents for improving the
fastness properties, the softener should be allowed to go onto the goods
first of all.
It is advisable to carry out preliminary plant trials in view of the many effects
that pretreatment, dyeing, printing, finishing and formulating the finishing
recipe may have on the colour fastness properties, shade, degree of whi-
teness, fabric strength, odour, handle, and possible ’’white crackling’’ after
washing. This applies particularly to white- and pastel-coloured and -prin-
ted goods, where there may be an adverse effect on the degree of white-
ness or the shade.
