How we scored it
Aqueous steam distillate: water (n = 1) plus trace holy basil volatiles (n = 1). Natural mass 100% = 1.00.
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
Dominant route is collecting the aqueous layer from steam distillation of the whole holy basil plant. No synthetic route is relevant to this ingredient.
In plain English
Holy basil (tulsi) hydrosol, the scented water collected when Ocimum tenuiflorum is steam-distilled. It is mostly water with traces of the plant's aroma compounds and is used for light fragrance and skin conditioning in toners and mists.
CosIng definition: Ocimum Tenuiflorum Water is the aqueous solution of the steam distillates obtained from the whole plant, Ocimum tenuiflorum, Lamiaceae.
