Abstract
The invention is concerned with novel modified candelilla waxes which are obtained by treating natural candelilla wax with magnesium, calcium, barium, zinc or aluminium hydroxide to such an extent that the product has substantially no acid number and a saponification number of from 5 to 20 units below that of the starting wax. The modified waxes of the invention do not, in contrast to natural wax, render tranparent PVC materials turbid during their processing, while the good properties of the natural lubricant remain unchanged.
