While, as pointed out above, the effective TFSA may be derived from {TAIL ~ a wide variety} of chemical reactants and may contain numerous different groups or moieties, I have found that particularly effective products are those which are described as an acylated polyether polyol having the formula: ##STR4## wherein: A is {HEAD ~ an alkylene oxide group}, Ci H2i O
