Sepimax Zen

Sepimax ZEN

INCI Name: Polyacrylate Crosspolymer-6
Recommended Usage Rate: 0.2–2%
Appearance: White to off-white powder
Function: Thickener, rheology modifier, stabilizer, suspending agent, and gelling agent

Product Overview

Sepimax ZEN is a versatile, pre-neutralized polymeric thickener and rheology modifier widely used in modern cosmetic formulations. It is valued for its ability to produce smooth, elegant textures while providing excellent viscosity control and formulation stability.

Unlike traditional carbomer-based thickeners, Sepimax ZEN does not require neutralization to develop viscosity. This makes it particularly convenient for formulators and suitable for a wide variety of skincare formulations.

It can be used to create anything from lightweight serums and fluid gels to richer creams and lotions, depending on the concentration and overall formulation.

Key Benefits

• Effective Thickening

Sepimax ZEN efficiently increases the viscosity of aqueous and emulsion-based formulations, allowing formulators to achieve the desired consistency and flow properties.

• Excellent Rheology Modification

It provides desirable flow characteristics and can help create formulations that feel smooth and elegant during application.

• Gel Formation

Sepimax ZEN can be used to create clear to translucent gel systems and is suitable for facial gels, serum-gels, spot treatments and other lightweight skincare products.

• Emulsion Stabilization

It can contribute to the stability of emulsions by improving the structure and viscosity of the continuous phase, helping to reduce separation and improve the overall consistency of creams and lotions.

• Suspending Properties

Sepimax ZEN can help suspend certain insoluble particles and functional ingredients within a formulation, making it useful for products where uniform ingredient distribution is important.

• Broad Formulation Compatibility

One of its major advantages is its compatibility with a broad range of cosmetic ingredients. It can be useful in formulations containing electrolytes and various active ingredients where some conventional thickeners may lose viscosity or become unstable.

• No Neutralization Required

Sepimax ZEN is pre-neutralized, so unlike conventional carbomers, it does not require the addition of sodium hydroxide, triethanolamine or another neutralizing agent simply to develop its viscosity.

• Suitable for Cold Processing

It can be incorporated during cold processing, making it particularly useful for formulations containing heat-sensitive botanical extracts, peptides and other temperature-sensitive ingredients.

Applications in Skincare

Sepimax ZEN can be incorporated into a wide range of cosmetic products, including:

• Facial serums
• Gel serums
• Gel creams
• Moisturizers
• Facial gels
• Spot-treatment gels
• Lotions
• Creams
• Cleansing gels
• Exfoliating gels
• Facial masks
• After-sun products
• Body care products
• Products containing suspended powders or particles

Typical Usage Rate

0.2–2%

The appropriate concentration depends on the desired viscosity, product type and overall formulation.

Lower levels can be used when a lightweight viscosity or fluid gel texture is desired, while higher levels can provide a thicker and more structured consistency.

How to Use

Sepimax ZEN can generally be dispersed directly into the aqueous phase of a formulation. Sprinkle the powder gradually into the liquid while mixing to ensure good dispersion and minimize the formation of lumps.

Allow sufficient time for the polymer to fully hydrate and develop its final viscosity. It can also be incorporated using suitable pre-dispersion techniques depending on the formulation process.

Always evaluate the final viscosity, pH, compatibility and stability of the finished formulation.

Why Formulators Choose Sepimax ZEN

Sepimax ZEN is particularly useful when a formulation requires viscosity, stability and an elegant skin feel without the need for a separate neutralization step. Its versatility makes it a valuable ingredient for both simple and advanced skincare formulations.

Storage: Store tightly sealed in a cool, dry place away from direct sunlight and moisture. Keep the container properly closed when not in use.
