Bulletin of the Rubber Research Institute of Sri Lanka,

Zinc stearate may also produce a modified bloom. With a solubility in rubber of some 0.3% zinc stearate should inevitably bloom as it is usually present in excess of 1% but its solubility is greatly increased by complexing with amines and, as these are generally present as cure residues, it normally remains in solution. However
