Polawaxes are general purpose emulsifying waxes. They are stable in the presence of metal ions, heat (autoclavable) and over a wide pH range. Due to their versatility Polawaxes can be used in skin systems, producing emulsions with excellent texture and stability. In skin care products the formation of liquid crystals within the emulsion promotes ‘time release’ hydration, and also functions as a slow release delivery mechanism for actives. Polawax A-31 is an emulsifying wax developed for use in aerosol quick-breaking foams. Recommended topical usage levels are 1-8%.
