NanoBase™ vs HLB Emulsion Systems
The Hydrophile-Lipophile Balance system was proposed by William Griffin in 1949 to keep an emulsion together in a jar for a year. Most skincare emulsifier systems today are still designed to that logic. NanoBase™ is an electrostatic tri-domain Architecture built on TDA Logic, the successor design logic to HLB, and engineered for nanoscale structure, not only for shelf storage.
The old way. The engineered way.
HLB Emulsion Systems
- Engineered in 1949 for jar stability, not for nanoscale structure
- Balance a numeric HLB value against an oil-blend requirement
- Droplets 1-10 micrometres, broad distribution
- Can be sensitive to active load, dilution or downstream chemistry
- Requires a matched surfactant system for every new oil phase
- Ships as separate ingredients, not as a finished raw material
- No designed home for each ingredient class
NanoBase™ Electrostatic Architecture
- Engineered for nanoscale structure, not only shelf storage
- Designed to a strongly negative electrostatic specification, not an HLB target
- ~185 nm design target, engineered to spec
- Designed to tolerate active loads, dilutions and downstream chemistry
- Trimodal by design: nanocolloidal, nanoliposomal, nanomicellar
- Ships as a finished raw material to any CM worldwide
- The finished formula built on it is the delivery system

What HLB actually is (and what it is not)
William C. Griffin published his Hydrophile-Lipophile Balance framework at a 1949 SCC meeting and formalised it in the Journal of the Society of Cosmetic Chemists shortly after. The framework assigns every surfactant a number from 0 to 20 based on its hydrophilic-to-lipophilic ratio, and every oil-phase requirement a matching number, and the formulator picks surfactants that add up to the target. It is a bookkeeping system for keeping an oil-and-water mixture from separating on a shelf. It is not a delivery framework, and it was never claimed to be one. Most skincare emulsifier systems in use today are still designed with Griffin HLB.
Why HLB stops at shelf stability
A 1-to-10 micrometre droplet distribution is set by the process, not designed. HLB emulsions can also become less stable when the shelf-storage assumption changes: introduce an active with a different polarity, dilute the emulsion at application, or swing the temperature, and the HLB balance can drift, the surfactants can re-partition and the emulsion can coalesce. The framework was designed for shelf stability, not for those conditions.
What an electrostatic Architecture does instead
NanoBase™ does not balance hydrophile against lipophile. It is designed to be held apart by electrostatic repulsion. The droplets in the architecture are designed to a strongly negative electrostatic specification, so like charges repel and the droplets are kept apart rather than coalescing. The design intent is a stabilisation mechanism that depends less on which active you add, the polarity of your oil phase, dilution at application or temperature. The Architecture is designed to stay intact under stress conditions that can destabilise HLB emulsions (design specification, not a tested comparison).
Three domains, not one phase
HLB treats an emulsion as one continuous phase with dispersed droplets. NanoBase™ is trimodal by design. The nanocolloidal domain carries lipophilic actives. The nanoliposomal domain carries peptides and amphiphilic actives. The nanomicellar domain carries water-soluble actives. Every ingredient the downstream formulator adds self-partitions into the domain built to carry it, rather than sitting stranded in the wrong phase, so the Architecture gives each active a domain designed for it.
Modularity, and any contract manufacturer
An HLB formula is a set of raw materials the CM has to combine correctly, hot-processed, with the exact surfactant blend the formulator specified. Change the CM and the process risk transfers with the formula. NanoBase™ ships as a finished raw material. The downstream cream, serum, mask, or treatment is built on top with gentle room-temperature mixing, at any contract manufacturer worldwide, with no specialised nano equipment on their side. Fully modular by design.
The verdict
HLB solved a real problem in 1949. TDA Logic is the successor design logic for nanoscale formulation. Where a finished product needs to hold under real-world stress and carry high active loads, NanoBase™ offers an engineered electrostatic Architecture, designed for nanoscale structure from the first design decision on; the finished formula built on it is the delivery system.
