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. It is a non-microplastic polymer.
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.
INCI: Polyacrylate Crosspolymer-6
Country of origin: France
Properties
- Ready-to-use: pre-neutralized powder
- Cold or hot process
- pH range: 2-8
- Multifunctional: thickening, stablizing and texturizing
- Extreme resistance to electrolytes up to 10% salt
- “Chassis” behavior 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
Benefits
- Clear aqueous gel
- Rich, elegant skin feel with a velvet finish
- Produces finer and softer foams in a hygiene product
Applications
- Face & body care
- Sun care
- Hair care
- Make-up
- Hygiene (shampoo, shower gel, facial cleanser, intimate hygiene, hydro-alcoholic gel…)
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.
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
- Clear aqueous gel
-
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
