Loving the cleaning effect of brine in soap, except that some friends say that they can notice that it has less lather (which I know is a sore point for some people).

Is it possible to add decyl glucoside to soap making (perhaps in the CP lye water)? .. and would decyl glucoside be able to lather well even in sea salt brine?

If this attempt is worthwhile, what rate can I add it for starters and to what extent might I need to start lowering my cleansing factor in soapcalc (which is currently at 21)?

Is there a way to understand final product properties for non-soap surfactants or to even compare these properties easily with soapcalc ratings?
