Read how we classify productsThe order is the manufacturer's own and follows concentration down to the one percent mark. Underlined names are flagged by our criteria. Names with a dotted underline open a short note on what the ingredient does in the formula. Names in bold are key ingredients. The 1% line is an estimate: the EU allows at most 1% phenoxyethanol, so the ingredients listed after it are present at about that level or less.
