What it sets out
Maximum 2.5 % as acid, rinse-off products. Packs don't print concentrations and we hold none, so no page here measures a product against it.
Lower limits apply to leave-on and oral products.
What we don't know
- Where it comes from — plant, mineral, synthetic — isn't recorded.
- How much of it is used in any particular product. We hold no concentrations at all.
