Identification & Functionality

Features & Benefits

Benefit Claims: Depilatory,
Excellent Tolerance,
High Functionality,
Low Viscosity,
Viscosity Boosting
Key Benefits: Ideal for highly alkaline and hard-to-thicken formulations

High viscosities at low use levels

Extremely user-friendly; can simply be added to water, neutralized and easily mixed

Can be neutralized by most commonly-used counter ions

Stable over time in the presence of heat and high pH; stable to hydrogen peroxide

Shear-thinning; formulation can be easily squeezed from an applicator, or mixed in a bowl, but will set up readily on the hair

Can also be used in one-component, pre-neutralized formulations such as hair dyes, gels and relaxers.

With just water, product will easily rinse from the hair.

Solvent tolerant

Structure 2001 and 3001 polymers can be blended to optimize the performance attributes of both (thickening + salt tolerance)

Typical usage: Aqueous gels, Hair treatment and Relaxers: 1.0% to 3.0%; Hair dye: 2.0% to 4.0%

Technical Details & Test Data

Technical Details: Viscosity

At low use levels, Structure 2001 polymer gives very high viscosity. The relationship between polymer solids and viscosity is logarithmic, not linear, meaning that small increases in solids produce large boosts in viscosity.

Stability

The Structure 2001/3001 polymer thickeners are stable over time in the presence of heat and high pH.

Salt Tolerance

Structure 3001 polymer shows outstanding salt tolerance and can build the viscosity of even a 2% solids sodium chloride solution.
