European Commission · source text, with formatting normalised · CC BY 4.0CAS and EC identifiers are source references. A botanical extract, polymer or mixture may have more than one identifier; a name does not establish purity, supplier grade or sourcing.
Matched through one source CAS and a confirmed ingredient name or source alias. These facts describe the matched PubChem record; they do not describe particle form, supplier grade or finished-product performance.
Dissolves or carries other formula ingredients. A solvent can help bring different components into a usable product.
Functions describe possible roles in a formulation. They do not establish the performance of every product containing this ingredient.
Aqua, water and eau are common label-language variants. Follow the complete product label when mapping names.
Water-based and anhydrous formulas are different formats. Not every cosmetic product contains water.
Applicable Cosmetics Rules and standards need to be checked for the ingredient, product type and use. Ingredient-specific restrictions have not yet been mapped here.
CosIng records do not authorise use. Check the current Cosmetics Regulation and annexes for restrictions and conditions.
FDA guidance has a US scope. Product classification, colour additives and other ingredient conditions require separate checks.
No personalised suitability or allergy assessment is provided. A source function is separate from human efficacy and finished-product testing.
