Vozol Neon 60k (20mg/50mg): clarifying mg vs % labelling and what to include on order forms
Nicotine labels explained: 20 mg, 50 mg, 2% and 5%
Nicotine statements on product pages sometimes mix a bare mass (mg) with a concentration shorthand (percent). Milligrams (mg) measure mass. Milligrams per millilitre (mg/mL) measure nicotine mass per unit volume. A percentage can mean mass per volume (% w/v) or mass per mass (% w/w) — the basis must be stated to convert precisely.
The retailer listing for Vozol Neon 60k displays nicotine options as “20mg / 50mg” in its specifications and as “2%,5%” in the product FAQ. Those published strings suggest strength options but do not, by themselves, state the concentration unit or the percentage basis. This note reports the seller’s wording; it does not verify a device, its contents or compliance beyond the published product text. Source: retailer listing.
Why the missing unit matters
A plain “20 mg” is incomplete as a concentration claim. If the intended meaning is 20 mg per millilitre, authors should write 20 mg/mL (or 2% w/v). If a percentage is used, the basis must be explicit: % w/v (mass per volume) or % w/w (mass per mass).
Concentration differs from total nicotine mass. Total nicotine mass = concentration × liquid volume. Neither concentration nor total mass alone tells you how much nicotine a person absorbs.
Percent to mg/mL — conversion table (mass per volume, % w/v)
For % w/v (grams per 100 mL): 1% w/v = 1 g per 100 mL = 1,000 mg per 100 mL = 10 mg/mL.
mg/mL = numerical percentage × 10
% w/v = mg/mL ÷ 10
Common equivalents (w/v basis):
0.5% = 5 mg/mL — 5 milligrams per millilitre
1% = 10 mg/mL
2% = 20 mg/mL
5% = 50 mg/mL
These are mathematical equivalents under the w/v assumption and do not confirm the product contents.
Why % w/w matters (and why density matters)
A mass‑per‑mass percentage (% w/w) reports grams per 100 grams of liquid. Converting % w/w to mg/mL requires the liquid density (g/mL):
mg/mL = numerical percentage × 10 × density (g/mL)
Therefore, 5% is not a universal synonym for 50 mg/mL unless the percentage is specified as % w/v. Where the percentage basis is missing, preserve the original seller wording and ask the supplier to confirm the convention.
What the webpage establishes (seller statements)
– Pack quantity: 10 units per box
– Warehouse: European warehouse
– Estimated delivery: 3–7 days
These are statements taken from the product page and should be treated as seller claims, not independent verification of inventory, dispatch location or regulatory status. Pack quantity and warehouse information are distinct from concentration wording and do not resolve missing concentration units. Source: retailer listing.
Spain and Italy context
Article 20(3)(b) of Directive 2014/40/EU sets a maximum nicotine concentration of 20 mg/mL for nicotine‑containing liquid within its scope. A declared concentration of 50 mg/mL would exceed that limit. A single 20 mg/mL declaration does not establish full regulatory compliance for any specific market. Consult national measures and the European Commission register for further detail. Source: EUR‑Lex (Article 20).
A translated product page or a European warehouse statement does not alone establish that every listed variant is authorised for sale in Spain or Italy. Confirm national permissions and exact product configuration with the supplier and, where required, competent authorities.
Short label‑check questions (copy to supplier)
English
Does “20 mg” on this listing mean 20 mg/mL? Is the percentage expressed as % w/v or % w/w?
Spanish
¿“20 mg” en este listado significa 20 mg/mL? ¿El porcentaje se expresa como masa/volumen (m/v) o masa/masa (m/m)?
Italian
«20 mg» su questo elenco significa 20 mg/mL? La percentuale è espressa come massa/volume (m/v) o massa/massa (m/m)?
Suggested short confirmation phrases (multi‑language) for supplier checks
English: Please confirm nicotine concentration format: “20 mg/mL (2% w/v)” or “50 mg/mL (5% w/v)”. If percentage basis is % w/w, please provide density used.
Spanish: Confirme formato de concentración de nicotina: “20 mg/mL (2% m/v)” o “50 mg/mL (5% m/v)”. Si es % m/m, indique la densidad empleada.
Italian: Confermate il formato della concentrazione di nicotina: “20 mg/mL (2% m/v)” o “50 mg/mL (5% m/v)”. Se è % m/m, fornite la densità impiegata.
Example order‑form fields (copyable template)
Use separate fields for the displayed seller text and your confirmed concentration format.
– product_name: Vozol Neon 60k
– pack_size: 10
– warehouse: European warehouse
– unit_price: 12.88 (as listed)
– listed_nicotine_label: "20mg / 50mg" (copy exact seller wording)
– listed_nicotine_percent: "2% / 5%" (copy exact seller wording)
– strength_field (confirmed): choose one per SKU, e.g. "20 mg/mL (2% w/v)" or "50 mg/mL (5% w/v)" — only use the parenthesis if the supplier confirms the % is w/v
– nicotine_basis_field: supplier confirmation required — values: "% w/v", "% w/w" or "mg/mL"
– supplier_note: free text for supplier confirmation (e.g. density if % w/w; lab test reference; batch photo)
A defensible procurement record preserves the original seller text (listed_* fields) and records your confirmed interpretation in the strength_field only after supplier confirmation.
Practical advice for buyers
– Do not auto‑convert a bare “20mg” to 20 mg/mL without supplier confirmation; that adds a denominator the original text did not state.
– Where a percentage is present but the basis is not, ask explicitly whether it is % w/v or % w/w and request density if needed.
– Request a legible photo of the physical packaging or a certificate if you must verify the label; screenshots of a webpage alone document only the page content, not the packaging.
– Keep pack_size, warehouse and delivery ETA recorded as seller statements, and confirm availability and export permissions for Spain and Italy separately.
Frequently asked questions (brief)
Does 20 mg always mean 2%? No. 20 mg as a mass is different from a concentration. The exact equivalence is 20 mg/mL = 2% w/v.
Is 5% the same as 2%? No — with the same percentage basis (w/v), 5% represents 50 mg/mL and is 2.5× the concentration of 2%.
Can a webpage screenshot verify a physical label? No. It documents what the webpage displayed; physical‑label verification requires an image of the packaging or direct inspection.
Does a warehouse statement prove availability or regulatory compliance? No. Warehouse location, current inventory, labelling accuracy and regulatory status require separate evidence.
