Sodium Laureth Sulfate is the primary surfactant in this formula. SLES is an ethoxylated sulfate: the ethoxylation process introduces a risk of 1,4-dioxane as a manufacturing impurity. While finished-product levels are typically low, three additional ethoxylated compounds are also present (PEG-55 Propylene Glycol Oleate, PEG-7 Glyceryl Cocoate, and Laureth-10), each carrying the same impurity pathway. SLES is also a recognised barrier disruptor with repeated use, particularly for sensitive and eczema-prone skin. Cocamide MEA is a nitrosamine precursor; the US cosmetics safety body advises formulators to verify that no nitrosating agents are present in such formulas. On the positive side, there is no synthetic fragrance, no parabens, and no artificial colour. As a rinse-off product, overall exposure is considerably lower than a leave-on formula would be.

SLES is an effective cleanser, but it sits at odds with a 'kind to skin' positioning for sensitive users. Milder alternatives such as Sodium Cocoyl Glutamate or Sodium Lauroyl Methyl Isethionate are widely used in sensitive-skin formulations and would better align with the brand's claims. Decyl Glucoside, a sugar-derived surfactant, and Cocamidopropyl Betaine, an amphoteric co-surfactant, meaningfully reduce the harshness of the SLES system. Bisabolol, derived from German Chamomile, is a well-evidenced anti-inflammatory active. Allantoin supports skin repair. Panthenol aids post-cleanse hydration. The soothing actives appear towards the lower end of the ingredient list, which suggests the concentrations are modest, though exact amounts are not publicly disclosed. Glycol Distearate creates the pearlescent texture but has no skin function.

The brand's 'no artificial perfume, no artificial colour' claims are verified from the ingredient list, which is a meaningful and genuine commitment for a mass-market cleanser. However, the 'no harsh chemicals' claim is not publicly supported: SLES is classified as a barrier disruptor in dermatology literature and is widely considered a harsh surfactant for sensitive skin. Its presence as the lead surfactant directly contradicts that claim. The full ingredient list is published on the brand website. PETA cruelty-free certification is independently verified. 'Dermatologically tested' is stated on-pack without a published report, lab name, or method.

Simple publishes the full INCI on the brand website, which is the foundational level of transparency. The 'dermatologically tested' claim is mentioned on packaging, but no study design, sample size, outcome data, or testing laboratory has been made publicly visible. No preservative efficacy test result is publicly accessible. No third-party safety assessment is linked. The brand mentions testing without providing the documentation that would verify it. This puts the evidence at a Grade C level, where the brand acknowledges testing exists but the supporting materials are not public.

Use instructions and suitability guidance for sensitive skin are clear on the product page. Frequency guidance for daily use is stated. The product page does not include explicit warnings about the barrier-disruption potential of SLES for eczema-prone users, which would improve honest guidance for the sensitive-skin audience this product is positioned for.
