Sepimax Zen® Thickener

Sepimax Zen® Thickener

Availability: In stock



Sepimax Zen® is a versatile pre-neutralised polymer that can create transparent aqueous gels on its own, or can work as a thickener and stabiliser in emulsions and surfactant based systems. It can be used in many personal care formulations (eg shampoo and body wash) to create thicker product with a rich and elegant touch, leaving a velvety feel on the skin. Basically, this is a polymer for making clear gels and adding a lighter skin feel in some moisturiser formulations.

Sepimax Zen® was designed to handle up to 10% salt and produces finer and softer foams in a personal care products. It works synergistically with fatty alcohols (eg. cetyl, cetearyl, or behenyl alcohols) to increase the viscosity in emulsions quite dramatically (use it up to 1% in the oil phase).

  • Efficient use at low levels
  • High resistance to electrolytes
  • Wide pH range, even at acidic pH
  • Suspending properties
  • Exhibits synergies with other polymers or emulsifiers, as well as fatty alcohols 
  • Synergistic with salt (NaCL)
  • Elegant sensory profile
  • Ready to use - no neutralisation required
  • Can be used in hot and cold process formulations
  • No clumping
  • Excellent particle suspension power

  • Take care when mixing: Do not over mix and avoid creating and trapping air into the gel as this can put the finished product under stress, speeding up oxidation and therefore creating instability or a disturbance/change in colour.
  • Sprinkle Sepimax™ Zen over the surface of the water phase and leave without stirring for 3 to 8 hours (or overnight) to hydrate.
  • If you have a mixer with RPM shown, you can sprinkle Sepimax™Zen over the surface of the water phase and blend using the lowest speed - approximately 500rpm initially and then slowly increase the speed to 1500rpm as you add the electrolytes (ie Salt), for approximately 10 minutes to allow it to hydrate.
  • For a creamy gel: sprinkle Sepimax Zen® into the hot or cold OIL phase. Then continue as usual, adding the oil phase to the water phase.
  • To thicken synergistically: Use 1% in the OIL phase with fatty alcohols (eg cetyl, cetearyl, or behenyl alcohols) to increase the viscosity in emulsions quite dramatically.
  • To increase foam density when formulating with surfactants: Use 2% to produce a creamy, soft, foamy lather. Used in this way you will also achieve thickening in anionic and non-ionic formulations.
  • Use at 1% to incorporate a high oil content (10 – 20% - we recommend small trial batches) into a gel when coupled with a natural polymer like xanthan gum, guar gum, agar, pectin and some cellulose
  • If you love Oliv-Emulse, but are having some stability issues, we suggest trying 0.6 – 0.8% Sepimax Zen into the water phase, hydrate as per previous instructions and proceed as usual.
