Why this score
Concern48 / 55
- Cocamidopropyl Betaine: watch if sensitive
- Fragrance: watch if sensitive
How much genuine, cited concern the ingredients carry, weighted by how much of each is likely present and whether the product stays on or rinses off.
Transparency12 / 20
- Uses an undisclosed "fragrance/parfum" blend, so its scent allergens are hidden.
Whether the full ingredient list, and any fragrance, are actually disclosed.
Formulation restraint18 / 25
- 2 known irritant or fragrance-allergen ingredients: Cocamidopropyl Betaine, Fragrance.
Needless irritant or allergen load for the product type. A clean, purposeful formula scores well without any "free-from" theater.

What’s inside
WaterGenerally safe
The base most products are built on. It carries the other ingredients and has no safety concern.
Full ingredient details →Sodium Cocoyl IsethionateGenerally safe
A coconut-derived mild surfactant best known as the main cleansing agent in syndet ("soap-free") bars and gentle body washes. It has a good tolerability record and is often chosen specifically for sensitive or eczema-prone skin.
Full ingredient details →Cocamidopropyl BetaineWatch if sensitive
A coconut-derived amphoteric surfactant used to boost foam and mildness in cleansers and shampoos. CIR has reviewed it as safe as used, but it is one of the more established contact-allergy triggers in personal care, usually traced to manufacturing impurities such as amidoamine and dimethylaminopropylamine (DMAPA) rather than the betaine itself. People with a history of eyelid or scalp dermatitis are more likely to react.
Full ingredient details →FragranceWatch if sensitive
An undisclosed scent blend that can contain dozens of components. The single most common cause of cosmetic contact allergy, and the blend is not itemized, so you cannot see what is in it.
Full ingredient details →Argan OilGenerally safe
A fatty-acid and tocopherol-rich plant oil used as a hair and skin emollient; CIR's review of plant-derived fatty acid oils found no evidence of irritation or sensitization and a long history of safe use in food and cosmetics.
Full ingredient details →Aloe VeraGenerally safe
A plant-derived water or extract used mainly as a soothing humectant filler. Evidence for dramatic skin benefits beyond mild hydration and soothing is limited, but it is well tolerated by most people.
Full ingredient details →Below the 1% line
Sodium BenzoateGenerally safe
The sodium salt of benzoic acid, used as a preservative in both foods and cosmetics. Decades of safety review support its use at typical cosmetic concentrations, with mild irritation the main reported issue in sensitive skin.
Full ingredient details →Citric AcidGenerally safe
Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.
Full ingredient details →Tetrasodium EDTACommonly feared, low concern
Tetrasodium EDTA is a chelating agent that binds trace metal ions to keep formulas stable and help preservatives work better. It has circulated online as a supposed "toxic" additive, but decades of safety review support its use at cosmetic concentrations.
Full ingredient details →Note: this product hides its scent as an undisclosed “fragrance/parfum” blend, so its specific allergens are not on the label.
