Abstract
Described are morphology stable wax compositions comprising the (trans)esterification product of a wax-forming composition comprising: (a) a triglyceride stock, a fatty acid stock, or a mixture thereof; and (b) a glycerol-based composition comprising glycerol, polyglycerol, or a mixture thereof. Methods of making the waxes are also described. The wax compositions may be used in candles, stack waxes, jell candles, cosmetics, food coatings, adhesives, board manufacturing (e.g., particle board and oriented strand board), urethane foams or coatings, alkyd coatings, coating formulation additives, printing additives, polymer processing agents, extrusion processing aids, polymer plasticizers, mold releases, polishes, and stick markers.
Claims19
A method of making a morphology stable wax composition comprising the steps of:
- (a) providing a composition comprising a triglyceride stock, a fatty acid stock, or a mixture thereof;
- (b) providing a glycerol-based composition comprising glycerol, polyglycerol, or a mixture thereof, wherein the glycerol-based composition comprises:
- about 75 wt % or greater total of polyglycerol species comprising diglycerol, triglycerol, and tetraglycerol;
- and up to about 10 wt % or less total of polyglycerol species of hexaglycerol and greater;
- and
- (c) reacting the composition of step (a) with the glycerol-based composition of step (b) under reaction conditions sufficient to transesterify the composition of step (a) with the glycerol-based composition of step (b) to produce the morphology stable wax composition.
