NanoBase™ and Colloid Science Glossary

This glossary defines the vocabulary used across nanobaselabs.com, written the way a skeptical professional formulator would want it: precise, unhyped, and consistent from page to page. NanoBase™ by Pensive Beauty® is a tri-domain nano-colloidal architecture, and the entire architecture is formulated to align with the Clean at Sephora standard. Where a term already has a settled meaning in colloid science, we give that meaning first and then note how NanoBase™ uses it, so the definitions below hold up whether you arrived from a textbook question or a spec sheet.

NanoBase™ Logic

NanoBase™ Logic is the design doctrine behind the Architecture. Instead of balancing a single emulsifier number to keep one phase from separating, it engineers three distinct nano-domains to coexist on purpose inside one pourable system, each matched to a different class of active. It is framed as the emerging successor to HLB logic, migration in progress rather than an established standard, and the full doctrine is set out on the NanoBase™ Logic page.

Tri-domain nano-colloidal architecture

Tri-domain nano-colloidal architecture is the term for the NanoBase™ system itself: a pourable aqueous system that is itself the continuous phase, stabilized electrostatically by design rather than nursed against separation. Inside it, a nanoemulsion domain, a nanoliposomal domain, and a micellar domain coexist as separate, purpose-built compartments rather than being blended into one average. The system word is architecture, not emulsion; see the full breakdown on the NanoBase™ Architecture page.

Nanoemulsion domain

The nanoemulsion domain is one of the three domains inside the architecture: a population of oil-core nanodroplets engineered to carry lipophilic actives, botanical oils, and oil-soluble vitamins. It is a domain within NanoBase™, not the whole of it; the architecture as a whole is a tri-domain system, never just a nanoemulsion.

Nanoliposomal domain

The nanoliposomal domain is the bilayer-vesicle population inside the architecture, built to carry amphiphilic actives and peptides that need both a water-friendly and an oil-friendly environment at once. Its bilayer is lecithin-based, discussed further under lecithin below.

Micellar domain

The micellar domain is the surfactant-micelle population inside the architecture, sized and charged to carry hydrophilic and surface-active actives that would not partition well into either of the other two domains. Together, the three domains let a formulator route an active to the compartment matched to its chemistry rather than compromise across a single carrier.

Continuous phase (sol)

In colloid science, the continuous phase is the medium everything else is dispersed in. In NanoBase™, that medium is an aqueous phase that already carries the three domains within it, rather than being added around them afterward. Colloid chemists also call a stable dispersion of this kind a sol, a particle-in-liquid system that pours and flows like a liquid instead of separating into layers.

DLVO theory and the electrostatic wall

DLVO theory (Derjaguin, Landau, Verwey, Overbeek) is the classical account of colloidal stability: as two particles approach, an attractive force pulls them together while electrostatic repulsion pushes them apart, and the balance between the two decides whether a dispersion holds or collapses. NanoBase™ reasons about the coexistence of its three domains through this framework, engineering interfacial charge so repulsion dominates and raises an energy barrier, an electrostatic wall, that keeps the domains from merging into one. That wall is a design principle we build toward, not a measured assay result or a published zeta potential; the full mechanism is set out on the architecture page.

Dynamic light scattering (DLS)

Dynamic light scattering, DLS, is the workhorse method for sizing sub-micron colloids: it watches how particles scatter light as they diffuse through a liquid and reconstructs a size distribution from that motion. It is the one characterization assay run on every batch of NanoBase™. DLS reports hydrodynamic size, not structure or morphology, and the full validation picture, including what DLS does not tell us, is on the research and evidence page.

Multimodal size signature

A multimodal size signature is what DLS resolves when more than one distinct population is present in a sample: more than one peak in the size distribution rather than a single narrow mode. For a genuinely tri-domain system, that breadth is the design doing its job, since a single narrow mode would mean the domains had merged rather than that the system had improved. We do not publish a numeric polydispersity index or describe the architecture as monodisperse, because a single tidy number would misrepresent a system built to be multimodal.

HLB (Hydrophilic-Lipophilic Balance)

HLB is a system William Griffin introduced in 1949 that assigns each surfactant a single number describing how hydrophilic or lipophilic it is. Matching the blended HLB of an emulsifier system to the required HLB of an oil phase is what keeps a classic emulsion from separating in the jar, and it remains a genuinely useful, widely used method three quarters of a century later. NanoBase™ Logic gives HLB full credit for that job and then asks a different question, detailed on the NanoBase™ vs HLB page.

Deposition

Deposition is the vocabulary NanoBase™ uses for how a payload behaves at the skin surface: landing, spreading, and remaining available on intact skin rather than travelling into or through it. We say deposition, not penetration or transdermal delivery, because NanoBase™ is a leave-on cosmetic raw material for intact skin, and we make no claim about what happens below the skin surface. Any statement about improved deposition traces back to third-party published literature on nano-scaled carriers, never to an in-house measurement.

Bioavailability

Bioavailability, as used in the literature we cite, describes how much of an active becomes available to act once delivered. A substantial body of independent, peer-reviewed research reports improved deposition and bioavailability from sub-200 nanometer carriers relative to their coarse counterparts, and where this site references that uplift, it is the published finding of other laboratories, attributed to them, never a NanoBase™ measured result and never a head-to-head test against an HLB-built system. NanoBase™ itself carries no actives, so it is not clinically tested; what a loaded formula achieves is the brand’s to substantiate.

Nanomaterial

Nanomaterial is a regulatory and scientific term, not a marketing one, and many standards and regulatory definitions cap it at particles roughly 1 to 100 nanometers in at least one dimension. NanoBase™’s three domains are engineered and DLS-characterized in the sub-200 nanometer range, which is nano-scaled in the ordinary sense but sits above that stricter 100 nanometer ceiling for at least part of the distribution. We describe the architecture as nano-colloidal and nano-scaled, and reserve nanomaterial for that narrower, size-capped meaning rather than applying it loosely to the whole system.

Empty chassis

Empty chassis describes NanoBase™ as it ships: a finished cosmetic raw material with its own INCI listing, deliberately carrying no actives until a brand adds them. It is a leave-on aqueous architecture for intact skin, not a finished product in its own right, which is why it is not itself clinically tested and makes no claim about what happens once actives are loaded. A brand or its contract manufacturer builds the marketable product on top of this chassis.

Cold-process

Cold-process, on this site, refers to how a brand’s finished formula behaves once it is built on top of NanoBase™, not to how the architecture itself is made. Pensive Beauty® manufactures the architecture; brands and contract manufacturers do not make or run NanoBase™ itself, they load their own actives into it by gentle, room-temperature mixing. That downstream finished formula is cold-processable at any qualified contract manufacturer on standard equipment, with no high-shear homogenizer or heat-and-hold step required.

Kinetic vs thermodynamic stability

Kinetic stability means a system resists change because of an energy barrier, not because it has reached the lowest-energy state; thermodynamic stability means a system already sits at that lowest-energy state and has nowhere lower to go. Classic nanoemulsions are kinetically stable, not thermodynamically stable: they are metastable systems whose longevity comes from an engineered barrier rather than from reaching equilibrium, a framework associated with McClements’ work on nanoemulsions. NanoBase™ lives inside that same paradigm, using its DLVO electrostatic barrier as the energy barrier that keeps the architecture kinetically stable, not a claim to have reached some new thermodynamic endpoint.

Lecithin

Lecithin is the INCI name for the phospholipid material that forms the bilayer of the nanoliposomal domain, specifically non-hydrogenated soy phosphatidylcholine, chosen for its fluid, room-temperature bilayer rather than a rigid, high-melting lipid. NanoBase™’s chassis is lecithin-based for this reason: a fluid bilayer pairs with the electrostatic wall for stability, rather than relying on lipid rigidity the way some legacy liposome systems do.
