NanoBase™ Cortex

Formulation Class: Haircar: Triple nanodomain delivery base for hair treatment

Primary Function: Ready water-phase + nano-structuring base that transports actives through the cuticle toward the cortex, while remaining easy to finish with rheology, conditioning polymers, and fragrance.

Developed for in-shower or leave-on hair treatments that require uniform spread, controlled penetration, and clean rinse sensorials. Cortex pairs nanoscale stability, adaptable to thin serums, rich masks, thermo-gels, or co-wash textures depending on modifier modules added.

Technical Foundation

NanoBase Cortex maintains a nanoscale droplet/vesicle distribution inside a cream-capable base and ships "ready for actives and texture," so formulators can plug in cysteamine, peptides/proteins, cationics, and rheology without rebuilding the base. Engineered to facilitate cuticle traversal and active availability near the cortex, using three integrated nanodomains—nanoemulsion, nanoliposomal, and nanomicellar—to stabilize diverse actives and enhance their mobility and performance at the fiber level.

  • Nanoemulsion domain: outer hydrophilic shell + lipophilic middle for even wetting and slip across the fiber surface

  • Nanoliposomal domain: hydrogenated lecithin + phytosterol vesicles for alkaline‑robust delivery of hydrophilic actives toward the cortex

  • Nanomicellar domain: dynamic micelle/solubilization capacity for mid‑polarity actives and fragrance

Formulation Performance Observations

  • Supports multiple textures: thin serums, rich creams, thermo-gels (thin-in-bottle, thick-on-hair), or co-wash fluids depending on finishing modules

  • Delivers consistent spread through roots and dense textures; supports even, cumulative outcomes

  • Clean-rinse sensorial with strong wet-combing when paired with cationic polymers

  • Maintains nano-structure under pH shift and common hair-treatment add‑ons (reducers, cationics, odor-control modules)

Formulation Compatibility

  • Stable under high shear/ultrasonication in manufacture; robust to post‑add mixing

  • pH stability range (as base): ships ~5.9; validated post‑build to 8.5 (stress to 9.0) for mild‑alkaline treatments

  • Compatible with: cysteamine HCl (mild reducers), polyquaterniums/cationic guar, poloxamers (thermo‑gel), peptides/proteins, amino acids, humectants, silicones or silicone alternatives, zinc ricinoleate + cyclodextrin odor control, alkaline‑stable fragrance

  • Not recommended with: high ethanol loads; strong anionic surfactant systems as the primary cleansing base (use Cortex Cleanse variant for co‑wash)

Use Case Examples

  • Texture softeners (mild‑alkaline, cysteamine-based; thermo-gel or cream-gel)

  • Bond‑repair and strengthening masks (acidic/neutral; peptides/dimaleates/amino acids)

  • Smoothing/conditioning treatments and rich rinse‑out conditioners (with cationics; optional silicones)

  • Deep‑moisture masks and leave‑ins (HA/PCA/panthenol + proteins)

  • Scalp serums and post‑service rebalancing rinses (Cortex Cleanse variant)

  • Shampoo & Conditioners

Notes on Customization

NanoBase™ Cortex can be modified into sibling variants to support: Fluid (serum‑light), Creme (richer mask), Cleanse (co‑wash/wash‑off), and Texture (mild‑alkaline focus), so brands can plug in actives and texture modules while retaining Cortex's three‑domain delivery and ready water phase.
