How we scored it
Lanolin wax with added -OH groups on its existing natural fatty chains; oxidation adds no petrochemical carbon fragment → 1.0
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Hydroxylated Lanolin is natural lanolin wax from sheep's wool that has been chemically treated to add hydroxyl groups, improving its water compatibility. The treatment modifies the natural wax in place rather than adding petrochemical mass.
In plain English
A skin-conditioning, emulsifying wax made from chemically modified sheep's-wool wax, altered to mix better with water while remaining wool-derived.
CosIng definition: Lanolin, hydroxylated
