Nanoemulsion (Nano CBD)
Also known as: Nano CBD, Nanoemulsified CBD, Water-soluble CBD
A nanoemulsion is CBD oil broken into droplets tens to a few hundred nanometers wide and held evenly in water by a surfactant, which is what most "nano CBD" and "water-soluble CBD" products are.
CBD is an oil-loving molecule, so it will not dissolve in water. Makers dissolve it in a carrier oil, then force that oil through high-pressure or ultrasonic equipment until the droplets are tiny. Published descriptions put nanoemulsion droplets roughly between 20 and 200 nanometers. A surfactant (an emulsifier, often a plant-derived one such as quillaja saponin or a synthetic one like polysorbate) coats each droplet so they stay apart. The result can look clear or slightly cloudy and mixes into water, which is why you see it in drinks (sources checked October 2026: cannabissciencetech.com and blog.sonomechanics.com).
Why brands use it: it makes CBD drinkable without a floating oil layer, and sellers often claim faster onset and better absorption. That second claim is the one to hold loosely. Smaller droplets are a reasonable idea, and the trade press describes higher bioavailability as an advantage, but the numbers a brand prints on a label are usually its own, not independent human data. What it costs: you add a surfactant to the ingredient list, you depend on the emulsion staying stable (droplets can merge and separate over time, and heat, light and storage matter), and you usually pay more per milligram. Ask for the droplet size, the emulsifier, and a batch COA that covers the finished product.
Where we sit: our drops are hemp extract in organic coconut-derived MCT carrier oil with real essential oil for flavor, taken under the tongue or in food, and our product pages describe our own process on the microemulsion page linked below. We do not market them as nano CBD and we do not print a nano-absorption number on the label. If you want CBD in a glass of water or a smoothie, a nanoemulsified product is built for that. If you take a dropper under the tongue, an MCT oil drop is the simpler, cheaper-per-milligram route. Start low, go slow, and talk to your doctor if you take medication.

- MicroemulsionA microemulsion is a stable mixture of CBD oil and water created by reducing CBD particle size to under 100 nanometers, dramatically improving absorption.
- BioavailabilityBioavailability is the percentage of a dose that actually reaches your bloodstream. CBD's bioavailability varies dramatically by delivery method.
- MCT OilMCT oil — medium-chain triglycerides, derived from coconut or palm — is the most common carrier oil for CBD tinctures because it improves absorption.
- SublingualSublingual means 'under the tongue.' CBD oil held under the tongue absorbs through the rich blood vessels there, reaching the bloodstream in 15-45 minutes.
- COA (Certificate of Analysis)A COA is a document from an accredited third-party lab certifying what is — and isn't — in a CBD product.
