Decode Label Safety Score
How we got 3.5 ShowHide
Methodology v3.1 (updated 8 Oct 2026) — what changed
The score is capped for a specific safety reason, set out below. This shampoo contains Methylchloroisothiazolinone and Methylisothiazolinone (MCI/MI), potent contact sensitizers that are prohibited in EU leave-on cosmetics and restricted in rinse-off products due to their high sensitization potential. While permitted in rinse-off products at controlled concentrations, their presence is a significant concern for individuals with sensitive skin or a history of contact allergies. The formulation also includes Sodium Laureth Sulfate, a surfactant that can cause irritation, and undisclosed 'Fragrance' which is a common allergen source. Despite the presence of some conditioning agents, the primary safety concern revolves around the sensitizing preservatives and potential irritants, making it less suitable for those prone to skin reactions.

Sources cited below may be Indian (FSSAI) or international (EU, US, WHO, IARC) — an international classification or law is evidence, not an Indian regulatory finding.
Methylisothiazolinone
MI and its chlorinated partner MCI are preservatives and recognised contact sensitisers. After MI replaced parabens in many products, European dermatology clinics recorded a sharp rise in contact allergy to it. Contact allergy, once acquired, is usually long-lasting, so people already sensitised to MI are advised to avoid it. EU rules ban MI from leave-on cosmetics (since 2017) and limit it to 15 ppm in rinse-off products. Whether a particular product causes a reaction depends on the person, the concentration and the contact time, which the label alone cannot show.
Regulatory & scientific authority Source: EU Regulation 2017/1224; SCCS Opinion SCCS/1521/13; British Journal of Dermatology (MI epidemic)
Methylisothiazolinone: regulation, sources and other products →Sodium Laureth Sulfate
SLES is a cleansing agent that is milder than SLS but can still irritate very sensitive or compromised skin. Separately, because it is made by ethoxylation, it may carry a residue of 1,4-dioxane, which IARC classifies as possibly carcinogenic to humans (Group 2B). The ingredient list cannot show whether any is present or how much. The EU SCCS considers 1,4-dioxane at or below 10 ppm in a finished cosmetic to be safe, and manufacturers reduce it by vacuum stripping.
Regulatory & scientific authority Source: FDA; EU SCCS
Sodium Laureth Sulfate: regulation, sources and other products →Fragrance Allergens (EU-listed)
These are individual fragrance components that are known contact allergens. EU rules require them to be named on the label when present above 0.001% (leave-on) or 0.01% (rinse-off), because "parfum" alone would hide them. Limonene and linalool are especially common and become more allergenic as they oxidise on exposure to air. This is a risk for people who are sensitised, not a general-population hazard.
Regulatory & scientific authority Source: EU Regulation 2023/1545 (extended fragrance-allergen labelling); SCCS opinions on fragrance allergens
Fragrance Allergens (EU-listed): regulation, sources and other products →Fragrance
"Fragrance" or "parfum" is a catch-all term that can conceal a blend of hundreds of undisclosed chemicals, including known allergens, sensitisers, and potential endocrine disruptors. The EU now mandates disclosure of 82 specific fragrance allergens. People with fragrance sensitivity, asthma, or contact dermatitis should prefer fragrance-free products.
Regulatory & scientific authority Source: EU Regulation 2023/1545; IFRA
Fragrance: regulation, sources and other products →Cocamidopropyl Betaine
Cocamidopropyl betaine is the usual "gentle" co-surfactant in shampoos, face washes and baby washes. It was named Allergen of the Year by the American Contact Dermatitis Society in 2004; the reactions are attributed mainly to impurities (amidoamine, DMAPA) and are uncommon, but it is a common cause of surfactant allergy in people with eczema.
Peer-reviewed research Source: American Contact Dermatitis Society - Allergen of the Year 2004; contact-dermatitis literature
Cocamidopropyl Betaine: regulation, sources and other products →Synthetic Cosmetic Colourants (CI)
These Colour Index (CI) numbers are colourants on the EU list of permitted cosmetic colours, each with conditions on where it may be used (for example, some are allowed only in products that do not stay in contact with mucous membranes). A listed colour in a product used as directed is not a finding of harm; the colour serves only to colour the product, and this is information for anyone who prefers to avoid synthetic dyes.
Regulatory & scientific authority Source: EU Regulation 1223/2009 Annex IV (permitted colourants); SCCS opinions on colourants
Synthetic Cosmetic Colourants (CI): regulation, sources and other products →Polyethylene Glycols (PEGs)
PEG ingredients are made by ethoxylation, which can leave traces of ethylene oxide (IARC Group 1) and 1,4-dioxane (IARC Group 2B) unless removed. Good manufacturing removes them, so the ingredient itself is not a hazard, but the label cannot tell you whether it was done well. PEGs should not be applied to broken skin.
Regulatory & scientific authority Source: IARC Monographs Vol. 100F (ethylene oxide) and Vol. 71 (1,4-dioxane); Cosmetic Ingredient Review
Polyethylene Glycols (PEGs): regulation, sources and other products →Decode Label Analysis
Contains Methylchloroisothiazolinone and Methylisothiazolinone (MCI/MI), potent contact sensitizers prohibited in EU leave-on cosmetics and restricted in rinse-off products due to high sensitization potential (Authority: EU Reg. 2016/1198).
Sodium Laureth Sulfate is a surfactant that can irritate sensitive skin and may carry a 1,4-dioxane impurity (IARC Group 2B, possibly carcinogenic to humans), though the EU SCCS considers ≤10 ppm safe in finished products.
Contains undisclosed 'Fragrance', a common source of allergens. EU regulations require specific declaration of named allergens above certain thresholds.
Cocamidopropyl Betaine is a recognized contact allergen, mostly due to manufacturing impurities.
Claim check
1 claim not supported by label dataFront-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 claim of '2X Softer* & Shiny Hair' is a subjective benefit that cannot be verified from the ingredient list alone.
The claim of 'Intense Hydration' is a subjective benefit that cannot be verified from the ingredient list alone.
This nutrient figure isn’t in our database for this product yet, so we can’t check the claim against the panel — it isn’t being called false, we just don’t have the numbers on file.
Sodium Hyaluronate is listed in the ingredients.
No parabens (e.g., methylparaben, propylparaben) are listed in the ingredients.

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.
The label declares each of these as a blend and then lists what is in it. The components appear in the groups above on their own merits, so the blend itself is shown here rather than counted a second time.

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.
