The science of soapmaking was not understood years ago.
You perhaps are thinking the knowledge of the science part of soapmaking, amongst the general population? Yes, this may well have been correct for those who just made a crude soap for washing clothes/general soap for the household.
But the companies that made soap comercially, some did make high end soaps following very high quality standards (i.e Vinolia Co. Ltd. as one example)
