N-DurHance™ A-1000

Restore and extend the look of virgin hair

Ashland brings an enduring dimension to hair repair and conditioning with the introduction of N-DurHance™ A-1000 conditioning polymer. Based on acrylate chemistry, the all-new polymer serves to restore hair typically damaged by certain cleansing regimens, treatments and heat styling back to the look of virgin hair.

A durable conditioning polymer that provides enduring shine and manageability

Providing a conduit for in situ controlled flocculation (ISCF™), N-DurHance A-1000 conditioning polymer returns damaged hair strands with hydrophilic properties back to a state of hydrophobicity. Excess positive charges emanating from the polymer will control in situ post flocculation on hair from the arrival of surfactants and conditioning agents, lending hydrophobicity to hair in a way that is both efficient and comprehensive.

N-DurHance A-1000 conditioning polymer properties

N-DurHance A-1000 conditioning polymer is a preservative-free aqueous solution of a highly charged cationic homopolymer of (3-Acrylamidopropyl) trimethylammonium chloride. It has been developed especially for use as a substantive and durable conditioning polymer for hair. It is supplied as an easily processable, ready to use 20% aqueous solution that requires no heating or pH adjustments. It is compatible with a wide range of cationic and nonionic surfactants and some anionic surfactants.


  • Restores damaged hair surface to a hydrophobic state
  • Provides a more semi-permanent conditioning effect
  • Benefits improve over the course of 5 washes
  • Wet comb-through significantly improved over commercial benchmarks
  • Reduces or eliminates the need for silicone conditioning agents
  • No build-up
  • Deposits uniformly on all hair types

Hydrophobic hair, from root to tip

Healthy virgin hair has a hydrophobic surface and is most often described as smooth, shiny and silky. Restoring hydrophilic damaged hair from dull-looking back to same hydrophobicity as virgin hair will significantly help to renew the hair look and feel.

In tests with various silicone-free (non-conditioning) shampoo, conditioner formulations containing 1% N-DurHance A-1000 conditioning polymer, improved the hydrophobicity of bleached hair to levels virtually the same as virgin hair.


Enduring performance with or without silicone

N-DurHance A-1000 conditioning polymer is enduring in both form and function. When used in rinse-off conditioning formulations with or without silicone conditioning technology, wet comb performance is outstanding. Wet comb energy tests on bleached hair demonstrate how the polymer chemistry contributes to both the look and behavior of hydrophobic virgin hair.


Manufacturers of rinse-off and leave-on conditioner systems now have new choices - enduring choices - to help consumers revitalize and restore their hair to the look and feel of virgin hair. N-DurHance A-1000 conditioning polymer offers consumer-perceivable hair repair and conditioning effects that last longer and perform better than silicone alone. In formulations containing silicone (or other conditioning ingredients), the polymer works by in situ controlled flocculation (ISCF) to post entrap the conditioning ingredients from any shampoo used.


Moreover, N-DurHance A-1000 conditioning polymer may be used on its own to achieve hair repair and conditioning effects in ways that is not possible with commercially available silicone compounds.

The polymer technology with optimized charge characteristics may be used in a range of formulation types to achieve nearly the same hydrophobic properties as healthy virgin hair, without build-up.

Find out how N-DurHance A-1000 conditioning polymer may be used in a variety of ways to achieve durable repair and conditioning effects never before possible with silicone compounds. Supplied as a ready-to-use 20% aqueous solution, N-DurHance A-1000 conditioning polymer requires no heating or pH adjustments. Compatible with cationic, non-cationic and select anionic surfactants, the polymer technology may be included in most rinse-off systems. Recommended dosage levels of 1.0 - 5.0% and packaged in 200L (50gal) polydrums. Contact your ChemPoint representative for technical information, product samples, and formulation concepts.



  1. Phase A: Disperse the Natrosol 250 HHR PC in the cold water first and heat up to 75°C while adding the rest of the ingredients.
  2. Phase B: Add the ingredients to Phase A, homogenize at 75°C and cool to 45°C.
  3. Phase C: Add in order, adjust the pH and cool further to below 30°C.
