Features & Benefits

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%
  • Available globally

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.
