Sepimax Zen Polymer Powder


SEPIMAX ZEN™ is a next-generation thickening, stabilizing and texturizing powder polymer. It has a MAXimal resistance to electrolytes and can be used to formulate with greater creativity and peace of mind.
SEPIMAX ZEN™ is the perfect polymer for building the “chassis” of formulations and addressing the challenge of stress-inducing and difficult active ingredients. It forms transparent gels with a velvety, rich and elegant feel. It is versatile and can be used in both skin care and hygiene products.  When there are fish eyes in your gels and emulsions, try hydrating more, mix with a gentler, less forceful mixing process, and wait 8 hours for full hydration.


  • Ready-to-use: pre-neutralized powder
  • Cold or hot process
  • pH range: 2-8
  • Multifunctional: thickening, stabilizing and texturizing
  • Extreme resistance to electrolytes up to 10% salt
  • “Chassis” behaviour in the presence of electrolytes (without viscosity drop)
  • Forms clear aqueous gels
  • Excellent particle suspension power
  • Sprayable fluid to thick textures
  • Synergetic effect with SOLAGUM™ TARA
  • Compatible with ethanol and other solvents, surfactants, AHAs, salicylic acid, zinc pyrithione, sun filters and sunscreens, pigments, etc.
  • Excellent vaginal tolerance

Emulsifier-stabilizer and thickener - 0.5 - 5%

Suspending properties - from 0.15%

Appearance: White powder
pH as supplied: 4 - 5.5 (When formulated in a 1.5% aqueous gel)
Stability: Stable between pH 2 - pH 8
HLB: Not applicable (Anionic)
Country of Origin: France

When used in a lotion, it can be used as a stabilizer for up to 15% oils and 4% electrolytes at as low as 2%. Without electrolytes, it can stabilize up to 20% oils.

For cream-gels, SepiMAX ZEN should be added in the oily phase (hot or cold). Its hydration time is approximately 10 minutes, but the polymer may also be left to hydrate for a few hours without stirring; then it can be mixed rapidly by dispersant agitation to obtain an aqueous gel.

 Sepimax™ Zen can be used to make low pH gels, and can be used with up to 4% glycolic acid, 0.1% magnesium chloride, and 0.2% EDTA. See details above regarding hydrating.

It is compatible with silicons, mineral oil, emollient esters oils and butters.  It is an anionic emulsifier, so it is not compatible with cationic ingredients.

Sepimax Zen is anionic so it does not work well with cationic ingredients such as BTMS-50 or Honeyquat PF.  However, it does work very well with electrolytes and acidic pH levels.  

Key benefits:

  • Efficient use at low levels
  • High resistance to electrolytes
  • Wide pH range, even at acidic pH
  • Suspending properties
  • Synergies with other polymers or emulsifiers
  • Elegant sensory profile
  • No neutralization
  • Can be used in hot and cold process formulations
  • No clumping

INCI: Polyacrylate Crosspolymer-6
