5.2.3 Lipophilic tensides<br />
Lipophilic tensides can be used as alternative to aminofunctional polydimethylsiloxanes<br />
used in polishes. The attractive shine and easy-cleaning surface<br />
that is obtained by using siloxanes can however not always be obtained to the<br />
same degree by using lipophilic tensides instead of siloxanes.<br />
5.2.4 Block polymers<br />
Block polymers consisting of polyethylenglycol and polypropylenglycol are a<br />
very applicable alternative to siloxanes in cleaning agents and polish products.<br />
The block polymer can be supplied with an extra alkyl chain by which the<br />
substance gets a lower surface tension that makes it possible to use the block<br />
polymer as antifoaming agent.<br />
Block polymers are some of the most used alternatives to siloxanes in cleaning<br />
and maintenance agents, but are still less widespread used than the siloxanes.<br />
Block polymers are in general more expensive than the siloxanes that can be<br />
used in this type of products.<br />
5.2.5 Summary<br />
It has been difficult to identify alternatives to siloxanes, because substitution<br />
of siloxanes has not had particular focus in the cleaning agent trade. Some<br />
alternatives have been used for several years, but have not been developed in<br />
the aim of substituting siloxanes, and it is a question to what extent they actually<br />
have similar properties. Siloxanes are mainly used as antifoaming agent<br />
and to provide shine and spreadability to polishes. The antifoaming properties<br />
can be provided by a number of alternatives at approximately the same price<br />
as the siloxanes, but often the properties of the alternatives cannot fully match<br />
the properties of the siloxanes.
