Decode Label Safety Score
How we got 3.3 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 several ingredients that warrant caution, particularly for individuals with sensitive skin or known allergies. The presence of DMDM Hydantoin and Methylchloroisothiazolinone/Methylisothiazolinone, both formaldehyde-releasing and potent sensitizing preservatives, is a significant concern, even in a rinse-off product where exposure is brief. While the product is designed to be washed off, repeated exposure can still lead to sensitization. The undisclosed 'Perfume' and multiple declared fragrance allergens further increase the risk for those with fragrance sensitivities. The primary surfactant, Sodium Laureth Sulfate, can also be irritating for some. This formulation may not be suitable for individuals seeking products free from strong sensitizers or undisclosed fragrance components.

Contains sensitizing preservatives and undisclosed fragrance with allergens
The score is capped for a specific safety reason, set out below. This shampoo includes preservatives like DMDM Hydantoin and Methylchloroisothiazolinone/Methylisothiazolinone, which are known to cause skin sensitization and are restricted in some cosmetic applications. It also contains an undisclosed 'Perfume' blend along with several declared fragrance allergens, which can be problematic for people with sensitive skin or fragrance allergies. The main cleansing ingredient, Sodium Laureth Sulfate, may also cause irritation for some users.

TEA-Dodecylbenzenesulfonate — anionic surfactant and emulsifier, can be a skin irritant.
Disodium EDTA — disodium EDTA is a chelating agent that keeps a product stable and clear. It has been flagged in some studies for potential endocrine-disrupting properties; regulatory consensus is not yet established, so it is noted as a low-level concern rather than a confirmed hazard.
Ingredient Concerns safety database
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 →DMDM Hydantoin
DMDM hydantoin slowly releases formaldehyde as a preservative mechanism. Formaldehyde is a known carcinogen (IARC Group 1) and potent sensitiser. It can cause allergic contact dermatitis. The EU restricts its maximum concentration and requires labelling that it releases formaldehyde.
Regulatory & scientific authority Source: IARC; EU Cosmetics Regulation Annex V
DMDM Hydantoin: 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 →Decode Label Analysis
Contains DMDM Hydantoin, a formaldehyde-releasing preservative. Formaldehyde is classified by IARC as Group 1 (carcinogenic to humans) and is a known contact sensitizer. (Authority: EU Reg. 2022/1181)
Contains Methylchloroisothiazolinone and Methylisothiazolinone, potent contact sensitizers. These are prohibited in EU leave-on cosmetics and restricted in rinse-off products. (Authority: EU Reg. 2016/1198)
Contains 'Perfume', an undisclosed fragrance blend that can contain numerous chemicals, many of which are common allergens and sensitizers. (Authority: EU Reg. 1223/2009 Art. 19)
Contains multiple declared fragrance allergens (Linalool, Benzyl Salicylate, Citronellol, ALPHA-ISOMETHYL IONONE, Hexyl Cinnamal) which can cause sensitization in individuals with fragrance allergies or sensitive skin.
Contains Sodium Laureth Sulfate, a surfactant that can be irritating to sensitive skin. It may also carry a 1,4-dioxane impurity (IARC Group 2B, possibly carcinogenic to humans), though levels are typically controlled to be below 10 ppm in finished products. (Authority: SCCS Opinion SCCS/1570/15)
Contains Cocamidopropyl Betaine, a mild surfactant that is a recognized contact allergen, primarily due to manufacturing impurities.
Combined Effects interactions
The combination of multiple potent sensitizing preservatives (formaldehyde-releaser and isothiazolinones) increases the overall risk of contact sensitization, especially for individuals with pre-existing sensitivities or frequent exposure.
The presence of an undisclosed 'Perfume' blend alongside multiple individually declared fragrance allergens significantly increases the overall fragrance allergen load, raising the risk of allergic reactions and sensitization for susceptible individuals.

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.
