Decode Label Safety Score
How we got 3.9 ShowHide
Reviewed 10 times · Methodology v3.1 (updated 8 Oct 2026) — what changed
The score is capped for a specific safety reason, set out below. This toothpaste contains Sodium Lauryl Sulfate, a known irritant for oral mucous membranes, which may not be suitable for individuals prone to canker sores or sensitive gums. While it includes beneficial ingredients like arginine and fluoride for oral health, the presence of an undisclosed 'Flavor' and the irritant surfactant are notable drawbacks.

Watch out for
Sodium Lauryl Sulfate (SLS) can irritate oral tissues and may contribute to canker sores in susceptible individuals.
The generic 'Flavor' ingredient does not disclose specific components, which can be problematic for those with sensitivities.
Limonene is a known fragrance allergen that may affect individuals with sensitive skin or fragrance allergies.
Titanium Dioxide — whitening agent — banned as food additive in EU (2022); potential genotoxin.
Sodium Saccharin — saccharin (INS 954) is a high-intensity, calorie-free sweetener, FSSAI/JECFA-approved with an established acceptable daily intake and considered safe within it. Some people prefer to limit or avoid intense sweeteners, so it is noted as a moderate, preference-level concern rather than a hazard.
Carrageenan — a natural thickener and stabilizer.

Titanium Dioxide (E171)
EFSA concluded in 2021 that titanium dioxide can no longer be considered safe as a food additive, citing genotoxicity concerns, and the EU banned its use in food from August 2022. It is still used in some cosmetics where skin absorption is the concern. Indian regulations are under review.
Regulatory & scientific authority Source: EFSA 2021; EU Regulation 2022/63
Titanium Dioxide: regulation, sources and other products →Sodium Lauryl Sulfate
SLS is an aggressive surfactant that strips skin of its natural oils, disrupts the skin barrier, and can cause contact dermatitis, canker sores, and eye irritation. People with eczema, psoriasis, or sensitive skin should avoid SLS-containing products. It is particularly harsh in oral care products where it contacts mucous membranes.
Regulatory & scientific authority Source: SCCS; American Academy of Dermatology; Herlofson & Barkvoll 1996
Sodium Lauryl Sulfate: regulation, sources and other products →Decode Label Analysis
Contains Sodium Lauryl Sulfate, a known irritant for oral mucous membranes, which may cause canker sores or irritation in sensitive individuals (EU SCCS).
The generic 'Flavor' ingredient lacks transparency, which can be a concern for individuals with specific sensitivities or allergies to undisclosed flavoring compounds.
Claim check
Front-of-pack marketing claims checked against this product's actual ingredients and nutrition. "Can't verify" means the label does not provide enough information to check the claim — it is not the same as the claim being false.
The supplied label data is insufficient to judge if the formula is advanced. No comparative information or specific criteria for 'advanced' are provided.
The supplied label data is insufficient to judge if this is a 'mega saver' product. No pricing or quantity comparison information is provided.
The label declares Sodium Monofluorophosphate, which remineralises enamel — the established mechanism behind this claim. The ingredient list supports it.
The label declares Sodium Monofluorophosphate — the recognised anti-caries active, and the agent cavity-protection claims rest on. The ingredient list supports this claim.
The ingredients list Calcium Carbonate and Arginine, supporting the claim of 'Calcium Boost with Arginine'.
In label order — normally largest quantity first. Select a row for the full write-up and sources.
Fragrance allergens are substances EU cosmetics rules require to be named on the label (such as Limonene and Linalool). Fragrant botanicals such as essential oils are grouped with them because they can naturally contain such substances, but they are not on that list. They matter mainly for people with fragrance allergies or already-sensitive skin — not a general-population safety issue. Each named allergen takes a small deduction from the ingredient score, and a high count can cap it; fragrant botanicals take none. Naming them on the label is a transparency positive.

About this analysis: Based on declared label information and available evidence. Decode Label does not independently laboratory-test products, and a score is not a regulatory determination or medical advice.
Disclaimer: Safety scores are Decode Label-generated assessments based on publicly available regulatory data (FSSAI, WHO, EFSA, IARC) and peer-reviewed research. They are not a substitute for professional medical advice, and they are not a regulatory determination, a laboratory safety certification or a medical diagnosis. Ingredient safety can vary by individual health conditions, concentration, and usage context. Decode Label is an independent information service and scores every brand by the same rules. No brand pays for or influences its score. Our founder also founded the personal-care brand Botani Bestie (see our story); its products are scored exactly like everyone else's. Data limitations: This assessment is based on the information declared on the product label and the evidence sources above — Decode Label does not independently laboratory-test this product. Ingredient concentrations, sourcing and manufacturing can vary between batches and are not always disclosed. A finding that is not shown here means it was not identified from the available label information, not that it has been ruled out.
