In the family’s tests: measured by an independent lab and compared against published safety limits.

Di(2-ethylhexyl) Phthalate (DEHP)11 ppbof 6 ppb

Over the limit — 1.8×US EPA drinking-water MCL, 40 CFR 141.61(c) — 0.006 mg/L. Applied to all foods as the TIGHTEST published DEHP number; the EU food-contact limit is looser (Reg. (EU) 10/2011 as amended by 2023/1442: SML 0.6 mg/kg, plus the 0.6 mg/kg DEHP-equivalent group limit with DBP/BBP/DIBP).

Bpf9.97 ppbof 10 ppb

Just under the limitNot on the EU Union list of substances authorised in food-contact plastics (Reg. (EU) 10/2011 Annex I), and Reg. 2024/3190 restricts hazardous bisphenols; no migration is permitted. Set at 0.01 mg/kg, the detection limit 10/2011 uses for not-detectable (ND) restrictions.

Dibutyl Phthalate13 ppbof 120 ppb

11% of the limitEU food-contact plastics, Reg. (EU) 10/2011 as amended by 2023/1442 — DBP SML 0.12 mg/kg (cut from 0.3). Also inside the 0.6 mg/kg DEHP-equivalent group limit (DBP x5).

Di (2-ethylhexyl) Terephthalate0.0353 ppmof 60 ppm

<1% of the limitEU food-contact plastics, Reg. (EU) 10/2011 — DEHT (FCM 798) SML 60 mg/kg, group restriction with DINCH. No tighter published limit exists (EFSA TDI 1 mg/kg bw/day).

Benzylbutyl PhthalateNDof 6 ppm

Not detectedEU food-contact plastics, Reg. (EU) 10/2011 as amended by 2023/1442 — BBP SML 6 mg/kg (cut from 30). Also inside the 0.6 mg/kg DEHP-equivalent group limit (BBP x0.1 = 6 mg/kg alone).

Measured in: Coke Zero Sugar Diet Soda

Bisphenol a (BPA)NDof 1 ppb

Not detectedEU Reg. (EU) 2024/3190 — BPA banned in food-contact materials from 20 Jan 2025 (old 0.05 mg/kg SML repealed); the residual exemptions require NO detectable migration at a 1 ug/kg detection limit. 1 ppb is therefore the tightest published number.

Measured in: Coke Zero Sugar Diet Soda

BPS (Bisphenol s)NDof 50 ppb

Not detectedEU food-contact plastics, Reg. (EU) 10/2011 — BPS (4,4'-sulphonyldiphenol) SML 0.05 mg/kg; BfR applies the same 0.05 mg/kg.

Not detectedDNHP (di-n-hexyl phthalate, EU Repr. 1B) is not on the EU Union list of substances authorised in food-contact plastics (Reg. (EU) 10/2011 Annex I), so no migration is permitted. Set at 0.01 mg/kg, the detection limit 10/2011 uses for not-detectable (ND) restrictions.

Diisobutyl PhthalateNDof 150 ppb

Not detectedEU food-contact plastics, Reg. (EU) 2023/1442 group restriction — DBP x5 + DIBP x4 + BBP x0.1 + DEHP <= 0.6 mg/kg DEHP-equivalents, so DIBP alone may not exceed 0.15 mg/kg. DIBP is not itself an authorised substance.

Common questions

Is Coca-Cola Zero Sugar healthy?

Coca-Cola Zero Sugar scores 0/100 on Tallow — our avoid band. That number comes from what is on the label: the ingredients, how processed it is, and what it is packaged in, plus lab results from its product family, Coca-Cola Zero Sugar (US). Per serving it carries 0g protein and 0g sugar. It is not a verdict on your diet — Tallow does not weigh calories, portion size or how often you eat it, so a high score means the ingredients are clean, not that the food is unlimited.

What is in Coca-Cola Zero Sugar?

Coca-Cola Zero Sugar lists 9 ingredients, starting with Carbonated Water, Caramel Color, Phosphoric Acid, Aspartame and Potassium Benzoate. Ingredients are listed in descending order by weight, so the first few make up most of what you are eating.

How many calories are in Coca-Cola Zero Sugar?

0 kcal per serving, or 0 kcal per 100ml. Calories are only part of the picture — Tallow scores Coca-Cola Zero Sugar on what the ingredients are, not how many calories they carry.

Does Coca-Cola Zero Sugar contain seed oils?

No. Nothing in Coca-Cola Zero Sugar’s ingredient list matches a seed oil — canola, soybean, corn, cottonseed, grapeseed, sunflower, safflower, rice bran or peanut oil, or an unspecified "vegetable oil".

How processed is Coca-Cola Zero Sugar?

Coca-Cola Zero Sugar is NOVA group 4: ultra-processed. That is the top of the scale and the classification the score penalises most heavily.

How does Coca-Cola Zero Sugar compare to other soda & soft drinks?

At 0/100 Coca-Cola Zero Sugar scores worse than most soda & soft drinks we have scored. A higher-scoring option in soda & soft drinks is Spindrift Grapeade Sparkling Water at 100/100.

Is Coca-Cola Zero Sugar organic?

Coca-Cola Zero Sugar is not certified organic in our data.

Has Coca-Cola Zero Sugar been lab tested?

Not this product itself. It shares a base recipe (US cola sweetened with aspartame and potassium benzoate, caramel color, phosphoric acid; incl. cherry/vanilla variants) with the other products in its family, Coca-Cola Zero Sugar (US), and 2 products in its family have been lab tested. This product is scored with the worst result for each contaminant across those tests. Those results are in the family's Contaminants section above; its own results may differ.

Does Coca-Cola Zero Sugar contain phthalates?

Coca-Cola Zero Sugar itself has not been tested for phthalates, but other products in its family, which share its base recipe, have: a lab detected DEHP at 11 ppb against a 6 ppb limit in Coke Zero Sugar Diet Soda and dibutyl phthalate at 13 ppb against a 120 ppb limit in Coke Zero Sugar Diet Soda. This product is scored with the worst result for each contaminant across those tests. Its own results may differ.
