CETYLDIMETHYLAMINE HYDROLYZED HEMPSEEDATE.

Valuable CAS - / HAIR CONDITIONING, SKIN CONDITIONING

A sophisticated cationic lipid complex that bridges the gap between deep hydration and surface refinement. This hemp-derived conditioning agent binds specifically to damaged areas of the skin and hair, providing a silky after-feel without the occlusive weight of traditional botanical oils.

Science

This molecule operates via ionic attraction; its cationic (positively charged) headpiece anchors to the naturally negative charge of the skin's keratin surface. Once attached, its hemp-derived 'tail'—rich in linoleic and alpha-linolenic fatty acids—integrates into the lipid barrier to reduce friction, enhance elasticity, and prevent moisture loss.

Key findings

  1. 01 Demonstrated significant improvements in skin tactile smoothness and 'after-feel' when utilized in structured surfactant systems at levels up to 5%.
  2. 02 Targeted deposition trials show the ingredient preferentially adheres to damaged fibers and compromised skin barriers to restore hydration without heavy build-up.

Because it contains the trendy 'Hemp' nomenclature, brands often include it at negligible levels (below 0.1%) for marketing claims. To achieve the functional conditioning and barrier-repair benefits identified in research, concentrations should ideally exceed 0.5%.

Stability

Possesses unique amphiphilic properties; it is water-dispersible but maintains lipophilic characteristics. It is most stable and effective in slightly acidic environments.

Synergies

  • Structured surfactant systems
  • Non-ionic emulsifiers
  • Glycerin

Conflicts

  • High concentrations of anionic surfactants
  • Carbomer (requires specific neutralization sequencing)
  • Highly alkaline environments (pH > 7.0)

Safety
