Nanoemulsion
A colloidal dispersion of oil droplets in water with droplet sizes of 20–200nm. Used to improve the water solubility and bioavailability of lipophilic cannabinoids.
In Depth
Cannabinoid nanoemulsions dramatically improve oral bioavailability by increasing surface area for absorption and bypassing some first-pass metabolism. Studies show nanoemulsion CBD has 4–5x higher bioavailability than oil-based formulations and faster onset (15–30 min vs. 60–120 min). Nanoemulsions are used in water-soluble CBD products, beverages, and pharmaceutical formulations. The technology also enables more consistent dosing by reducing the food effect on absorption.

Decarboxylation
The chemical process by which a carboxyl group (COOH) is removed from a molecule, releasing CO₂. Converts inactive cannabinoid acids (THCA, CBDA) into their active forms (THC, CBD).
THCA (Tetrahydrocannabinolic Acid)
The acidic, non-psychoactive precursor to THC found in raw, unheated cannabis. Converted to THC through decarboxylation.
CBDA (Cannabidiolic Acid)
The acidic precursor to CBD found in raw cannabis. Converted to CBD through decarboxylation.
Lipophilicity
The tendency of a molecule to dissolve in fats, oils, and non-polar solvents rather than water. Cannabinoids are highly lipophilic.
Myrcene
The most abundant terpene in most cannabis strains. Produces an earthy, musky aroma. Proposed to enhance cannabinoid absorption and contribute to sedating effects.
